I think this was really well done. People are commenting on the way it "looks"...I think that at this point weight reduction is about functionality rather than aesthetics. Great video, man!
I was going to comment about weight reduction. If you've already got a functional fibreglass part, adding the carbon and resin only adds weight. What's the actual goal of this? Weight or bling?
You basically told fresh lemons how to make and build its own lemonade stand all in one video. This formula of build makes perfect sense. Using cast compound to mold a cast is in my opinion the best simple builds I have ever seen on youtube because you also presented how to troubleshoot.
if you follow this guys steps and take your time it should come out. now if your finished product doesnt look smooth as glass like a carbon fiber hood thats because you have more things to do. you would need to sand it all down smooth and cosistent. then use a fine sand paper and clean it up and make it all consistent again. clean and wipe it all up with aclohol. then get a paint gun and spray a clear gel coat. then polish and finish. its not just a walk in the park for beginners unless they just have a natural talent, its rare but does exist. just be patient, and put time into your work. turn on some jams get real organized. clean as you go, and keep a real nice work space while doing this stuff. i have 10 years + doing composite work, mainly aircraft. theres a reason i get paid big money for this work.
I have to admit when i first clicked on the link i was expecting it to be a bit of a joke but that being said the end product was really cool. Obviously not the prettiest carbon tube out there but something that can be done by any guy in a shed its pretty impressive!
Some of these people commenting are pretty ignorant. This is "true carbon fiber". He's just using a base layer of fiberglass. It becomes one piece not a wrapped piece. No different than using two different weaves when laying up glass. No different than using a hybrid weave of carbon fiber. It's still real carbon fiber it's just not a 100% carbon fiber layup.
Tru that and I would rather have the rubber hose on the inside so you don't have to worry about thin spots or failure and pulling bits into your intake and engine actually brilliant having the rubber tube on the inside I think anyway but opinions are like ass holes every ones got one. Some people just have one at both ends that spew different types of shit. LOL
It’s actually more of a composite as it will retain the properties of both fiberglass and carbon. There are always a shit ton of keyboard warriors on these videos that act like they are scientists lol
True, but the quality is shit, and not a smooth finish with noticeable lines from the casting material. No doubt it is functional. I think aesthetics is also important when it comes to custom work, no doubt this part is "unique".
Everyone has their own methods but i personally like the put the resin on top of the carbon instead of before putting it on. i find it faster and gives me time to adjust the carbon how i want it. your piece turned out pretty good :)
Wow, Thanks for responding to your comments, very cool of you! Im making a mold of a steel pipe off a turbo kit that has a MAF flange on it that I'm not longer going to use(just straight pipe with an Abaco 85mm MAF) I bought all the carbon fiber and needed tools I learned from your vids. Just wanted to say thanks man! I'll send you a photo (if it comes out nice).
This is for an induction tube? How do you deal with the interior of the tube being so rough? Would this cause unwanted turbulence on the induction charge?
Keep in mind if you go to a place like Easy Composites UK (check out their cool video series too), you can get fillet wax designed to fill the seam gaps between the pieces. And yeah, they do a lot a work that looks absolutely amazing on the outside when ironically they should technically be more concerned with the inside finish, which is often difficult to get good, so people should value this idea. Easy Composites offers a full line, including release agents so your split pipe form could be wrapped directly in CF.
Hey there youngster, youtube's pulling out some oldies for its recommended. I'm not complaining. Be interesting to see how you would make this now. Would you change anything?
Dude, if you take 10 minutes to precut/fit your peel ply you wont have to spend an hour cleaning up that mess afterward. Also on more complicated pieces, you can make a foam or plaster mold covered with wax paper, soap, silicone, plastic, etcetera, to keep it from sticking. These molds can be destroyed to removed them from the inside of the cured composite. Alternatively, you can make several smaller pieces then wrap them all together when your done to form the larger and/or more complicated piece.
Derek Fricke I have not...you can get a smooth finish with the process I used. You just need to smooth the fiberglass before overlaying the carbon fiber.
Wow !!! I'm a fan of urs !!! Ur good ! And very skilled . I don't own a hot car but I do own a motorcycle . Hopefully u could come up with something on a sports bike .. But thanks for your time and demonstration
you should really sand the fiberglass part first 80 grit or less. Once fully cured and after sanding the epoxy can actually make a pretty great bond other wise it usually dosn't take much to separate them. The cool thing about that stuff on the other hand is the pin holes and deformities that will also help to make a pretty good mechanical bond. cool the way you make tubes though!
Well.. I think a few people have already pointed out ways you could improve finish with a mould, release compounds and pre cut peel ply but also you've kind of misunderstood the purpose of vacuum moulds. The vaccum is set at one side of the mould and the resin drawn in from the other end allowing it to work its way through the material evenly. To be fair you would probably have had a similar if not better result simply doing a lay up and applying resin with brush and roller then lacquer afterwards.
One thing I have learned in the carbon fiber class in taking is to plug the ends if your doing tubes. This way the bag won't pop from the vacuum. Anyways good job man I did learn a thing or two.
I know this is an old video, but this was just what I was looking for to make an intake tube. For the sleeve material, how much does it expand/stretch? I've got a 4 inch OD intake tube with a couple of bends that i've 3d printed; will have to shrink it by the thickness of the CF for the mold. Should I buy the 4 inch sleeve? The only size I see below that from most manufacturers is 2.5. I'm considering using water soluble PLA to make the mold. Is the single layer of CF strong enough without doing a second layer that's in a different direction? Thanks!
Some other tips on vacuum bagging... Instead of using that black sealing tape you can use Clip-n-Seal Bag Clips available on Amazon. They are reusable and come in 40" lengths. As far as the bag on smaller parts I use the FoodSaver bag material because you can get it on a roll. you can find that on Amazon too or at Target or other stores. You can use the Clip-n-Seal Bag Clips on both ends and you have a custom length bag that is much more durable than the trash bag it looked like you used. It is often reusable too.
haha.. you cant smooth suck shit made tube with anything, only using 1kg of filler you can make it smooth making it 10x heavier than was meant to. Thats what you get when you have no skills.
great vids! with this project could you skip the cast tape part and use a release agent on the metal mold with holes drilled in the end caps to get a smoother finish?
Despite the nay Sayers - this is a fantastic method and a great method of improvisation ! To the nay Sayers who apparently are perfect in every way - why are you here ? You are all driving cars that don't need this , you have people building your cars with perfect skills- in fact you probably have you own channels right ? Why don't you trolls go somewhere else and let these gifted people share their skills ? Again I say this is a fantastic method , can it be improved ? ,yes . Is it the west I have seen ? Hell no ! I have a race car and will adapt to this method - the ground work is there ..thank you so much for sharing - Monster Cooper Al
Quick question not sure if it's been asked I'm looking into making a intake tube as well but are you able to just used an aluminum tube then use the same method you did above?
JERPERFORMACE yea you can do that. I have wrapped tubes before and then just split one side to remove it from the original. Once it has been removed you can glue the seem and re wrap.
+ben dunn not sure. I know the vac pump pulls off excess resin and allows the part to be a light as possible. I would say just give it a try and see how it turns out
would it be better to make it out of PVC piping first, You can heat up PVC and make the bends then carbon fiber tube wrap around it. Or cut the pvc in fours put mould release on it and take it out like u did with the metal tubing?
you could I guess the only problem would be that you can mandrel bend PVC. When you heat it and start to bend the diameter of the tube starts to close.
this is tight and dont look difficult.. was wondering ever done some canards?.thats what brought me to this video because i wanna do a diy carbon fiber canards on my suby..
+The Fab Forums they are kinda like a splitter but they go on the sides of the bumper and in most cases you see 2 of them.usually a small one half way up the side of the bumper and the other is a little bigger but same shape but more lower on the bumper and usually theyre more on import tuner cars and are used to help with downforce
+Ed Ruiz Gotcha. I have not personaly done any but there is a guy over on my forum that does alot of that kind of stuff. I would bet he could help you out. thefabforums.com/main/index.php?topic=1281.0
Do you have anything showing joining a tube to a flat sheet of CF? Placing threaded inserts into a part so that the CF piece can be bolted to other parts?
I would like to see the carbon fiber composite tube without the lines from the cast wrapping. Could you possibly use a wax on the disected metal tubing as the mold? Then a thin layer of resin on the tube, insert tube in carbon fiber, resin carbon fiber, wrap, and finally put in vacuum bag? That would seem to yield better quality results.
+The Fab Forums I'm new to this and sorry if this question has already been asked. Why not skip the fiberglass and just do the Carbon Fiber? It looks like it would be really easy to just use the Carbon Fiber sock over your metal 4 piece tube (that you used to make the fiberglass tube). Am I missing something?
Well I could but I wanted to show the process if a mold that can't be separated can't be used. Like a tube section that's several feet long. You would have to use a fiberglass base.
So if I would happen to use this method to create piping for a turbo setup for my car. Are these gonna melt in any case or something like that? This may be a stupid question in someones opinion but I am kind of new to cars and just today started learning so help me out haha.
I'm thinking about buying a cheapo injen intake and wrapping the tube in cf like this. Is there any benefit for have a cf intake tube? Or is only to look cool?
Very interesting. I went bigger turbo and they dont make an inlet thats budget friendly, and i dont exactly want to piece 4 silicone pipes together. May have to give this a try
Hey which diameter of carbon fiber did you use from that website? It says " will compress about 20-25% and tension about 60-65% from their base diameter." So would I need the 4" or 2.5", and when you pick quantity does it come in seperate one foot increments or continuous? Thanks.
One small note. The casting material has a polyurethane resin. Epoxies do not bond well to poly-u's. It is just fine for what you are doing with it but I liked the idea for making a mold to make 100% carbon parts. Thanks for the vid.
Did you place the perforated release film on top of the part? I am working on a skinning part, I tried adding the peel ply and then the release film but instead of having a gloss finish like I intended it have a matte finish as it sucked out all the resin.
I've watched all of you inlet tube videos I'm really interested on making one but I had one question.. from you experience how does to tape and carbon fiber wrap around say a vacuum line connector comming from the side?
Hey bro, what you using for clear parting film? It gives a nice gloss. If I run short of peel ply I use 100% polyester dress/jacket liner, from Fabricland.
You don't. If you use this method it stays as a hybrid. You can how ever just put the carbon fiber right on the four piece steel mold and not use the fiber glass if you choose.
very cool stuff, I'm watching a number of video's you've made. I'm interested in turbo set up, I have a 65 fastback would like to run twin turbo's on a 351W. any suggestions?
so here is my overbudget66.blogspot.com/ been chipping away at it and it's looking good. let me know what you think. it's just a body now with doors, I'm looking at a rotisarie to get it on it's side so I can detail under side then install front and rear suspension. Then I will start down the path of motor trans etc. your feed back would be good as I don't share this blog really with anyone it's more of my own chronicle of progress. have a good weekend.
+stkmltS I do if I cant get a perfect seal. If you can get the bag to where it has no leaks you can just pinch the line shut and turn off the vac pump. Perfect seal can be hard to get sometimes though.
The Fab Forums is showing one of a dozen ways to do one job. There is more than one way to skin a chicken. Videos take time, money for products, etc. As for camera angle, he did not hire a skilled camera man from union scale to add to the cost. Haters, if you can do it better, then go for it. I did not find your videos when searching this topic. As a retired ASE Master tech, time is money as we fought the clock all day. At least this guy is taking the time to show you "ONE" way of doing a task, for that and all that is involved, I give him two thumbs up / subscribe. Some jobs don't pay well, but if you sit at home in your PJ"S, on grandma's couch, because that is all you can do....get out, take moms car and go see the monkeys at the zoo. Teach them the right way to throw crap as some posting below are experts at one task.
hopefully not a super stupid question but what is a good place to buy carbon fiber sheet, epoxy, and hardner? I watched the "you need this tool video" which was hilarious, but some of the links are broken.
Could you use aluminum tube to fad up a cast, then use plaster to get and inside diameter mould? Cut the tube off and lay the cf wrap over the plaster?
The Fab Forums Well, my thought was.. Smooth air flow = better power. Maybe have the inside extrude honed to smooth airflow even more. Also, the outside of the tube would be smoother. I neglected to type the part about removing the plaster after the cf is cured.
could you make a vid about making front rear and side bumpers from skratch? would like to make some spare ones, bumps break them all the time. Thanks and keep up the awesome work!
Thanks for feedback...I think bumpers are a little over my head. I do have some guy on www.thefabforums.com that are making bumpers though. They have step by step build posted right now.
Very new to fabrication in general but extremely interested. Getting somewhat reasonable at welding, and Id like to do this sort of intake tubing on my 89 Mustang GT. Right now I have my intake going from the MAF into the fender and down to the foglight hole in the bumper cover (jerry rigged a bracket to hold everything together with the absence of foglight/foglight bracket) and it works great but looks like frankenstein shit. Any suggestions on doing this with such a crazy angle? And also the best way to make your steel molds?
Gorilla Panic cool I love fox bodies. When I make molds from steel I usually just tack sections of mandrel bends together to make the mold, however you could also use some kind of foam, shape it, wrap it and then melt the foam out with acetone leaving you a perfect tube. I have not tried this my self but I have heard of this technique from a lot of others.
So I watched a lot of your videos and subscribe myself, and now I am wondering if I can use my OEM motorcycle fairings as molds (I have a GSX-R 1000 13)... It won't gonna break them? Thanks for the video, man. You are awesome... And I liked the way you deal with thw hate in the comments. Best regards from Brazil.
Really, really cool idea... something that I am going to do very soon - thanks for the ideas :). Two questions if you don't mind: 1 - How much pressure can these tubes actually take? 2 - How would you go around the additional lines that usually are in the tubes? Like vacuum lines, sensor holes and so on (if you tried those kind of pipes yet). Thanks! :)
mrN3w7 Thanks, I have some pressure testing videos on my channel ua-cam.com/users/thefabforumscom where they hold 30 psi no problem. As far as any external port, they can be plumbed after the fact pretty easily with some to part epoxy.
joshua stoffregen We have pressure tested it up to 30 psi with no issues. We actually have video of it on our channel. I have used these on cars in the past and the heat didn't seem to affect it any but not sure under boost. I am thinking of making some for the twin turbo mustang project we also have on the channel.
You can also use nylon "peel ply" directly over the carbon fiber before you put on the breather (white layer). It will allow the excess resin to pass through the peel ply and go into the breather. This will make a stronger part. The finished part will look more matte and not glossy and will be a much better surface if you wanted to add another layer of cloth. The peel ply will not peel off as easy as the plastic though. They do make peel ply that is coated now for an easier release.
Wait, I don't understand it. If you put blue plastic tube into carbon... How do you take it out? I mean, what's the difference between this, and wraping it with M3 carbon? I don't understand, and I want to, because I tink this is so cool, I just want to know what's the point.
Ok, I know I sound like a hater, but I'm not, really. I supscribed to your chanell, because it's awesome. I just wan't to know, if you say it's fiberglassed tube, and we all know that there is no reason for her to be strong, because no one is gonna touch her but only air, explain me, please, what is point of putting carbon fiber on fiberglassed tube, and combinining them, rather then puting 3M carbon vinyl?
+JDMTurboful No problem. The carbon fiber is for strength. The idea is to use these tubes on boosted applications. Here is a video of some pressure testing I did. Fiberglass alone would never stand up to this kind of pressure. ua-cam.com/video/_oZtQ7WOQsA/v-deo.html
I have a question I have a 1994 Volkswagen Jetta 2.0 liter engine but I want to do my whole tire cold air intake system I made out a bunch of aluminum parts into a carbon fiber set up that would be awesome and I saw how you did yours but then I want to know is it possible to make one of the intake manifold because mine's a two piece intake manifold I was wondering is it possible to convert that into make a mold or something how to do it to make a cold air intake system for intake manifold I want to convert my intake to a carbon fiber or fiberglass one is it possible
christopher hoyt I could have...mainly trying to show the options with these materials. Also using one layer of each can save money compard to two layers for CF
No problem. I have put a list of companies that sell everything you need under the buying resource section in the fabrication forums on the thefabforums.com site.
does anyone know how well the expoxy and carbon hold up to heat, im doing a bottom mount turbo setup, where the intake as well as compressor output will be realitvley close to the turbo manifold. i can make some aluminum heat sheilds but those with only block so much heat haha. the pip will probaly be within 1.5 inchs of the turbo manifold
okay cool, i found some high heat resins on ebay that i think will work well. im gonna try to minimize the heat with header wrap, heat shields, and wraping the carbon in heat reflective tape. nice video too, you give a lot of nice fab ideas with your channel
No idea if this has been mentioned earlier in the comments, I really don't have the time to go through all of them, but I think you're over complicating the whole process. Instead of casting it, why not just wrap a couple of CF sleeves over it, apply the resin, and pop the tube out after it cures. You'd end up with a smoother product that required less clean up. Hell, to make it cheaper, you could use a FG sleeve and a CF sleeve over the top.
Jacob Walker Yea your absolutely correct. I have had a few other ask about the same thing. I wanted to show the whole process of casting the glass section just in case the tube parts that were being made were too big or complex to get the steel mold out. Some long runs of tube have to use the alternate method of splitting the fiberglass to get it off the steel tube form.

Great work mate-super impressed with how simple you have made this-great work.
Thanks...I never could find a simple way to do this so I created my own...
This is for an induction tube? How do you deal with the interior of the tube being so rough? Would this cause unwanted turbulence on the induction charge?
wickedkustumz The inside of the tube is actually extremely smooth. It being wrap tight against the tube creates a very smooth surface on the inside.
Even if there was some pits on the inside it would act like a golf ball where the pits hold pockets of air and the rest flows over smoothly
Keep in mind if you go to a place like Easy Composites UK (check out their cool video series too), you can get fillet wax designed to fill the seam gaps between the pieces.

Well..

The vaccum is set at one side of the mould and the resin drawn in from the other end allowing it to work its way through the material evenly.
To be fair you would probably have had a similar if not better result simply doing a lay up and applying resin with brush and roller then lacquer afterwards.
The advantage to vacuum lay up is to remove excess resin and to compress the part as it kicks....what you are talking about is called vacuum infusion.
Foam method? What’s a good base to start with material wise? Foam tube?, aluminum or PVC, In order to make the mold. Thank you
One thing I have learned in the carbon fiber class in taking is to plug the ends if your doing tubes. This way the bag won't pop from the vacuum. Anyways good job man I did learn a thing or two.
lol...yea I wish I would have plugged the ends on this one. It worked out
Yea Ive been trying to make just a straight pipe and they way you did it by cutting it into quarters is a good idea..
Brent Elliott thanks
I know this is an old video, but this was just what I was looking for to make an intake tube. For the sleeve material, how much does it expand/stretch?

thats for the info
You are remarkable. In spite of apparent failures you just keep on plugging. Keep it up.
+Adam Pierce I dont believe in failure...
+The Fab Forums It's the only way to get good. Accept it.
+The Fab Forums It's only failure if you refuse to learn from it. Fail well/forward.
PS Love the videos.
I never fail, I just discover new ways that don't work. Great video!
A pun, and a backhanded compliment. Well done.
Excellent demonstration! Please include sanding tips/material and recommended clear coat
Thanks...I may do another video finishing it
The Fab Forums Would you consider investing in one or two more cameras to provide viewers with different angles of viewing experience?
haha.. you cant smooth suck shit made tube with anything, only using 1kg of filler you can make it smooth making it 10x heavier than was meant to. Thats what you get when you have no skills.
great vids! with this project could you skip the cast tape part and use a release agent on the metal mold with holes drilled in the end caps to get a smoother finish?
yea you could do that. I kind of tried to show the two techniques together in one video
TheFabForums.com Would you need to do a double layer of CF to ensure a good seal?
I probably would for strength and seal. It still wouldnt be very think.
Love the idea but is there a chance the casting tape is gonna deteriorate and send chunks of material into your engine?
Jon Zengotita I have never had any issues with it. Its not plaster...the casting tape is a stronger form of fiber glass.
oh ok good to know, wasn't sure what it was made of. thanks for the info, im gonna try to make some of these for my wrx

you could I guess the only problem would be that you can mandrel bend PVC. When you heat it and start to bend the diameter of the tube starts to close.
maybe if you put sand in it before you bent it so it keeps it shape
That might work. I have done that with steel before with some success.
this is tight and dont look difficult.. was wondering ever done some canards?.thats what brought me to this video because i wanna do a diy carbon fiber canards on my suby..
+Ed Ruiz Canards? What are those?
+The Fab Forums they are kinda like a splitter but they go on the sides of the bumper and in most cases you see 2 of them.usually a small one half way up the side of the bumper and the other is a little bigger but same shape but more lower on the bumper and usually theyre more on import tuner cars and are used to help with downforce
+Ed Ruiz Gotcha. I have not personaly done any but there is a guy over on my forum that does alot of that kind of stuff. I would bet he could help you out. thefabforums.com/main/index.php?topic=1281.0
+The Fab Forums oh alright tight ill check it out n thanks for the replies.you have some cool stuff on your channel
+Ed Ruiz Thanks
Do you have anything showing joining a tube to a flat sheet of CF? Placing threaded inserts into a part so that the CF piece can be bolted to other parts?
I don't....what are you trying to make?
Brake duct spindle outlet... to be bolted to a hub
hmmm...you could make the tube and flat piece together as one part. I would have to see what it is exactly to give you anymore feedback.
Very cool stuff! Why can't you just put the carbon fiber directly on the metal template and skip the casting tape?
you could that for sure....some parts are just to big or complex to use the metal form
Thanks for the information and great video. How long did it vacuum for before letting sit overnight?
This is an awesome idea I would love to make a bonnet entry snorkel for my 4wd using this method
I would like to see the carbon fiber composite tube without the lines from the cast wrapping. Could you possibly use a wax on the disected metal tubing as the mold? Then a thin layer of resin on the tube, insert tube in carbon fiber, resin carbon fiber, wrap, and finally put in vacuum bag? That would seem to yield better quality results.
yeah you could pre smooth the casting material before applying the carbon
+The Fab Forums I'm new to this and sorry if this question has already been asked. Why not skip the fiberglass and just do the Carbon Fiber?
It looks like it would be really easy to just use the Carbon Fiber sock over your metal 4 piece tube (that you used to make the fiberglass tube). Am I missing something?
Well I could but I wanted to show the process if a mold that can't be separated can't be used. Like a tube section that's several feet long. You would have to use a fiberglass base.
+The Fab Forums Ah, Ok. That's excellent, thank you!
So if I would happen to use this method to create piping for a turbo setup for my car. Are these gonna melt in any case or something like that? This may be a stupid question in someones opinion but I am kind of new to cars and just today started learning so help me out haha.
I have used them in the engine may before...not sure how they would do boosed though
@@Thefabforums allright thanks for the response! I guess I will find out haha.
I'm thinking about buying a cheapo injen intake and wrapping the tube in cf like this. Is there any benefit for have a cf intake tube? Or is only to look cool?
weight and doesnt heat soak like metal or aluminum
you deserve a hell of a lot more subs man
+Based Pony thanks
so you leave the pump on overnight as well? wouldnt that blow up the pump pretty quickly?
The pumps do well. I have not had any issues with pumps blowing up yet.
Very interesting. I went bigger turbo and they dont make an inlet thats budget friendly, and i dont exactly want to piece 4 silicone pipes together. May have to give this a try
I have a 90 cobra twin turbo project and I was wondering what do you use to make the mold for the air induction box or for even a hood or fender
cobra clone? molds are different depending on what I am making
Great job, very educational as usual, keep it up.
Thanks...appreciate the feed back
Hey which diameter of carbon fiber did you use from that website? It says " will compress about 20-25% and tension about 60-65% from their base diameter." So would I need the 4" or 2.5", and when you pick quantity does it come in seperate one foot increments or continuous? Thanks.
I ordered the 4" so the weave would be tighter on final part. it comes in continuous length.
Thanks for posting such a helpful video. Great demonstration with lightweight and easy to use materials.
+Jacob Jensen No problem...thanks for watching
One small note. The casting material has a polyurethane resin. Epoxies do not bond well to poly-u's. It is just fine for what you are doing with it but I liked the idea for making a mold to make 100% carbon parts. Thanks for the vid.
David Bohm Thanks for the feedback
Also wanted to say thanks for the awesome video and taking the time to answer everyone's questions here, great work and valuable informations!!!
tunermaxima3000 No problem...thats why I do what I do.
will a carbon fiber intake conduct heat or will it keep the inside airflow relatively cool?
+Bishop Cherry Coke does not conduct any heat...that's really a better perk then the weight compared to aluminum
Did you place the perforated release film on top of the part? I am working on a skinning part, I tried adding the peel ply and then the release film but instead of having a gloss finish like I intended it have a matte finish as it sucked out all the resin.
+Maksim Shirokov yeah. i use the release as the peel ply
thank you very helpful!! your video is fantastic I am doing the same to make a set of intake tubes for my mercedes
I've watched all of you inlet tube videos I'm really interested on making one but I had one question.. from you experience how does to tape and carbon fiber wrap around say a vacuum line connector comming from the side?
I have no experience with that
nice to see somebody who knows there shizz.. good vid man
Thanks...appreciate the feedback
Great ideas on how to make a carbon fiber part.
thanks
Well shit Kyle, woven carbon fiber tubes, I didn't know that existed but it sure makes things easier it seems!
Do you have a link to the epoxy and vacuum bags you used?
Hey bro, what you using for clear parting film? It gives a nice gloss. If I run short of peel ply I use 100% polyester dress/jacket liner, from Fabricland.
I use a perforated peal ply
Thanks for the reply! Where do you order it from if I may ask?
NM....I found a slew of em, but none in Canada, gotta import it in.
Nice, but how do you take out the blue mold? ?
You don't. If you use this method it stays as a hybrid. You can how ever just put the carbon fiber right on the four piece steel mold and not use the fiber glass if you choose.
very cool stuff, I'm watching a number of video's you've made. I'm interested in turbo set up, I have a 65 fastback would like to run twin turbo's on a 351W. any suggestions?
+Scott Herbert sweeet...I am sure I could talk for days on suggestions. The setup I am doing is a 351 base so its close to what you are looking to do.
so here is my overbudget66.blogspot.com/ been chipping away at it and it's looking good. let me know what you think. it's just a body now with doors, I'm looking at a rotisarie to get it on it's side so I can detail under side then install front and rear suspension. Then I will start down the path of motor trans etc. your feed back would be good as I don't share this blog really with anyone it's more of my own chronicle of progress. have a good weekend.
What did you use to seal the bag???
Did you leave your vacuum pump running overnight while the part cured?
+stkmltS I do if I cant get a perfect seal. If you can get the bag to where it has no leaks you can just pinch the line shut and turn off the vac pump. Perfect seal can be hard to get sometimes though.
The Fab Forums is showing one of a dozen ways to do one job. There is more than one way to skin a chicken. Videos take time, money for products, etc. As for camera angle, he did not hire a skilled camera man from union scale to add to the cost. Haters, if you can do it better, then go for it. I did not find your videos when searching this topic. As a retired ASE Master tech, time is money as we fought the clock all day. At least this guy is taking the time to show you "ONE" way of doing a task, for that and all that is involved, I give him two thumbs up / subscribe. Some jobs don't pay well, but if you sit at home in your PJ"S, on grandma's couch, because that is all you can do....get out, take moms car and go see the monkeys at the zoo. Teach them the right way to throw crap as some posting below are experts at one task.
hopefully not a super stupid question but what is a good place to buy carbon fiber sheet, epoxy, and hardner? I watched the "you need this tool video" which was hilarious, but some of the links are broken.
I will take a look at those. There are a ton of places. Just search Carbon Fiber and you will get some of the top places to buy it.
gorrila carbon works
Could you use aluminum tube to fad up a cast, then use plaster to get and inside diameter mould? Cut the tube off and lay the cf wrap over the plaster?
+Jeff Greer I guess you could but why would you want to do that?
The Fab Forums Well, my thought was.. Smooth air flow = better power. Maybe have the inside extrude honed to smooth airflow even more. Also, the outside of the tube would be smoother. I neglected to type the part about removing the plaster after the cf is cured.
If I would to do this in a intake I have already it should work right??
You shouldn't have any issues
could you make a vid about making front rear and side bumpers from skratch? would like to make some spare ones, bumps break them all the time.
Thanks
and keep up the awesome work!
Thanks for feedback...I think bumpers are a little over my head. I do have some guy on www.thefabforums.com that are making bumpers though. They have step by step build posted right now.
Very new to fabrication in general but extremely interested. Getting somewhat reasonable at welding, and Id like to do this sort of intake tubing on my 89 Mustang GT. Right now I have my intake going from the MAF into the fender and down to the foglight hole in the bumper cover (jerry rigged a bracket to hold everything together with the absence of foglight/foglight bracket) and it works great but looks like frankenstein shit. Any suggestions on doing this with such a crazy angle? And also the best way to make your steel molds?
Gorilla Panic cool I love fox bodies. When I make molds from steel I usually just tack sections of mandrel bends together to make the mold, however you could also use some kind of foam, shape it, wrap it and then melt the foam out with acetone leaving you a perfect tube. I have not tried this my self but I have heard of this technique from a lot of others.
awesome video thanks got my weekend sorted now
awesome....thanks
So I watched a lot of your videos and subscribe myself, and now I am wondering if I can use my OEM motorcycle fairings as molds (I have a GSX-R 1000 13)... It won't gonna break them? Thanks for the video, man. You are awesome... And I liked the way you deal with thw hate in the comments. Best regards from Brazil.
right on. welcome to the channel. You cant use the fender it self as the mold but you can make a mold out of the fender.
Really, really cool idea... something that I am going to do very soon - thanks for the ideas :).
Two questions if you don't mind:
1 - How much pressure can these tubes actually take?
2 - How would you go around the additional lines that usually are in the tubes? Like vacuum lines, sensor holes and so on (if you tried those kind of pipes yet).
Thanks! :)
mrN3w7 Thanks,
I have some pressure testing videos on my channel ua-cam.com/users/thefabforumscom where they hold 30 psi no problem. As far as any external port, they can be plumbed after the fact pretty easily with some to part epoxy.
They can handle a lot of pressure but make sure you don't try to build a submarine like this and go visit the titanic. That's too much pressure.
Like Christmas morning!
lol...yea pretty much, thats probably why I like making stuff.
Can this be used for turbo applications? Would it hold up to the heat?
joshua stoffregen We have pressure tested it up to 30 psi with no issues. We actually have video of it on our channel. I have used these on cars in the past and the heat didn't seem to affect it any but not sure under boost. I am thinking of making some for the twin turbo mustang project we also have on the channel.
Thank you!
No problem...anytime
You can also use nylon "peel ply" directly over the carbon fiber before you put on the breather (white layer). It will allow the excess resin to pass through the peel ply and go into the breather. This will make a stronger part. The finished part will look more matte and not glossy and will be a much better surface if you wanted to add another layer of cloth. The peel ply will not peel off as easy as the plastic though. They do make peel ply that is coated now for an easier release.
Thats what I used in this video - carbon - peel ply - breather cloth - vac bag...
TheFabForums.com
Sorry my bad. I saw in another video of yours the resin going through the peel ply. I didn't notice it in this video.
No worries
Wait, I don't understand it.
If you put blue plastic tube into carbon... How do you take it out? I mean, what's the difference between this, and wraping it with M3 carbon?
I don't understand, and I want to, because I tink this is so cool, I just want to know what's the point.
What blue plastic?
Blue tube. Sorry.
Blue tube at a beginning. Do you take it out at the end, or does she stay in that carbon cover?
Its not plastic. Its fiberglass, and the two of them stay together to create a strong hybrid composite.
Ok, I know I sound like a hater, but I'm not, really. I supscribed to your chanell, because it's awesome. I just wan't to know, if you say it's fiberglassed tube, and we all know that there is no reason for her to be strong, because no one is gonna touch her but only air, explain me, please, what is point of putting carbon fiber on fiberglassed tube, and combinining them, rather then puting 3M carbon vinyl?
+JDMTurboful No problem. The carbon fiber is for strength. The idea is to use these tubes on boosted applications. Here is a video of some pressure testing I did. Fiberglass alone would never stand up to this kind of pressure. ua-cam.com/video/_oZtQ7WOQsA/v-deo.html
Is Only Benefit Weight Reduction? How Does This handle Heat As An Air Intake Hose As Opposed To Composite or Aluminum? -Thx
doesnt heat soak like aluminum does
I have a question I have a 1994 Volkswagen Jetta 2.0 liter engine but I want to do my whole tire cold air intake system I made out a bunch of aluminum parts into a carbon fiber set up that would be awesome and I saw how you did yours but then I want to know is it possible to make one of the intake manifold because mine's a two piece intake manifold I was wondering is it possible to convert that into make a mold or something how to do it to make a cold air intake system for intake manifold I want to convert my intake to a carbon fiber or fiberglass one is it possible
Yeah I have some video on this channel where I made a two piece boxed manifold.
Really good idea with that cast rap nice thinking
thanks
Dad Dunning you Ned to get out more!
Just recently came across your channel.
Great job, loving the work
Keep it up.
Thanks...I have some stuff coming soon
Does the vacuum needed to do this ? Great vid
SMAC creations No you would have to use vacuum but it helps.
Hi,
Thank you so much for all your videos. Where can I source the fiberglass cast making material from?
Thanks, and keep up the good work.
Sea Eagle I actually get it on ebay. Just search casting tape. I like the 3M stuff. I think is called scothcast.
Thanks for watching.
@tim m. That makes it a fiberglass wrapped with carbon fiber part
Yes it does.
Good Video. To make it one step better though, perhaps some simple text at the different assembly points might be helpful.
do you take the center fiberglass mold out?
no I just mold them together. Because its not traditional fiber glass there is no worries of it flaking
Can you pls suggest me how to make a bike fender with carbon fiber
To have the original?
Do you know where I can get these sleeves in different color carbon/Kevlar?
I dont...sorry
Dude, this was pretty cool. Instant subscriber. Do you have any new updates on the turbo fox? Keep up the FYI/DIY videos.
Thanks...no major updates right now. I hope to finish the mini chopper then get back on the twin turbo fox
hi nice vid ! the tape how much temperature can take ?
Will this work over a metal or aluminum tubing?
I sure it would but putting over those would defeat the purpose
I just like the look, maybe it will help keep my charge pipes cool
can u use just the cadting tape by itself and add more layers for Construction
+Adam Crow yeah you could do that
I can's seem to find the carbon sock tube where do you get it from?
try acpsales.com....tell them thefabforums sent you.
TheFabForums.com wicked thanks mate keep up the good work
Can this be done to plastic?
since your vacuum bagging why not just go straight from the four piece plug?
christopher hoyt I could have...mainly trying to show the options with these materials. Also using one layer of each can save money compard to two layers for CF
very nice.
You can make the carbon fiber direct to the steel tube that you used to do the fiber glass tube.....just an idea....
Correct
I want show that step though because some may be making long and complex tubes that won't allow a steel mold to be removed.
+The Fab Forums True....but I got ideas for my '73 KE20 Corolla
Sweet
thank you for posting this video. where do i get all the materials
No problem. I have put a list of companies that sell everything you need under the buying resource section in the fabrication forums on the thefabforums.com site.
How would you go about doing an intake manifold ?
I have a video on here where I build one. I think it was the the first 3 videos I ever did
how did you do to get the hose out of tube?
Could you simply use the carbon fiber over the original mold? Would it not be financially feasible over using a glass substrate
you could. I wanted to show the process because not all mold are removable the way this one was.
where to buy carbon fiber in tube ? I have already searched it everywhere , but it is not to find
If you don't have a vacuum bag can you dunk it under water in a bag?
dont think it would be quite the same
does anyone know how well the expoxy and carbon hold up to heat, im doing a bottom mount turbo setup, where the intake as well as compressor output will be realitvley close to the turbo manifold. i can make some aluminum heat sheilds but those with only block so much heat haha. the pip will probaly be within 1.5 inchs of the turbo manifold
I have used them on intakes with no issues...there are high heat resins that will withstand around the 250 degree mark I think
okay cool, i found some high heat resins on ebay that i think will work well. im gonna try to minimize the heat with header wrap, heat shields, and wraping the carbon in heat reflective tape. nice video too, you give a lot of nice fab ideas with your channel
In theory, could this be done with carbon fiber sheets?
TheRabbitt23 you mean like pre cured sheets of carbon or are you just talking about carbon fabric?
Carbon fabric and resin. Would that be possible?
Yea you could probably do it. It would be difficult, time consuming, and messy though.
No idea if this has been mentioned earlier in the comments, I really don't have the time to go through all of them, but I think you're over complicating the whole process. Instead of casting it, why not just wrap a couple of CF sleeves over it, apply the resin, and pop the tube out after it cures. You'd end up with a smoother product that required less clean up. Hell, to make it cheaper, you could use a FG sleeve and a CF sleeve over the top.
Jacob Walker Yea your absolutely correct. I have had a few other ask about the same thing. I wanted to show the whole process of casting the glass section just in case the tube parts that were being made were too big or complex to get the steel mold out. Some long runs of tube have to use the alternate method of splitting the fiberglass to get it off the steel tube form.
great vid. keep up the good work.
Thanks for the feedback
