You guys delivered on this video! Great production quality, and the parts turned out great too. Keep up the excellent work. We've enjoyed following you guys.
This video autostarted for me, and half way in I was thinking "I haven't watched DarkAero for a while, they might have something new" I'll watch them next, and here you were, in the comments.
Your videos are so good and professional. I could watch them all day. I have been following this build with interest. Seems like the complicated video you made. Thank you.
Thanks Carl. It’s the most content we’ve put into a ‘series’ so far and the physical scale of the component made for more work too! It’s always more interesting for us when it’s a real project, not just a demo, because real projects always throw up challenges that you would just avoid for a simple demonstration. Hopefully Alex and the team will get to have their adventure later this year which will complete the story!
@@easycompositestv first time doing tubes and going to try a few techniques. Wanted to order from you guys but due to the brexit i'm gonna wait till there is a definit agreement on transfers across europe.

I mentioned before that I’m wanting to make a Fiat 500 carbon fiber hood identical to yours made a while back. Covid has hit my family he’s and sadly my plans have come to a stop. I’m trying to source an affordable vacuum pump here and some good quality carbon chips to skin a carbon diffuser that was cracked by a hit and run idiot in a parking lot last spring. Skinning it with forged fibers and vacuum bagging it would surely make it look amazing. It’s cracked along tope edge and is all consmetic. I used a baking soda a cyanoacralte mixture when it happened to keep the crack from spreading. Eventually, I’ll remove, fill and skin and possibly tint the coating. The part is so much lighter and it was almost $1000.00 new, I’d hate to trash it. In the mean time please keep up the great work and since the forged look is in, can you do a video showing a cosmetic skinning or epoxy tuning to influence a color difference? Thank you and please keep the vids coming, the education is priceless
Thanks Sean, great to hear from you and learn what your working on. For sure this pandemic has put a lot of plans on hold, including some of ours. We’ll certainly do some tutorials working with chopped carbon but, as you might expect, ours may be a little bit of a different take compared to what’s out there already. All the best with your projects.
Hello, still very greatfull for your very informative video's, been enjoying them very much. I have a question.. I would like to duplicate som rather small vintage polyester RC Airplane landing gear. They were very nicely made and very becoming to the plane due to there shape and finish. However they were too weak by design. I would like to duplcate them in Carbon fibre but due to the LG being very thin blades (like miniature limbs of a bow and arrow) I am having trouble to come up with a plausible way of making the mould. So... I thought, maybe I can make a 2 part siliconerubber mould and combine it with infusion.. Would that work or would the mould collapse under the vacuum ?
Amazing video, I just had one question that what are the specifications of that vaccum pump and if I had to buy the similar one, where can I get it. Thanks for everything, the video has helped me a lot to start my journey from upgrading from Hand Moulding to Resin Infusion.
We're using our EC4 Vacuum Pump; full details and specification can be found by following the link: www.easycomposites.co.uk/ec4-composites-vacuum-pump
Great video! I am trying to make my own moulds via vacuum infusion, using vinilester gelcoat, poliester resin, and glass fiber... But I am having issues from lack of adherence from resin to gelcoat... Could you give me any advice? Thank you!
Not all vinylester gelcoats are compatible with polyester resins unless they have been specifically designed to be. You may be better off using a vinylester resin on the back of the gelcoat layer and then follow that up with polyester. We have a uni-mould tooling system specifically developed for such applications.
Hi, i work with infusions myself, bigger parts tho, and we are having some trouble, i have a question for you, is siphoning of the resin not an issue for you, as your source is above your inlets? we want to move the source above the inlets, because our infusiion is going to slow, but the engineers are afraid of siphoning
Absolutely awesome job once again. I live in a more rural part of Florida in the US and have ordered from you guys on several occasions now and each time have received the products within 48 hours. Absolutely unreal!!! Keep it up!
Brilliant. Watching these videos over the past few months has really sparked my imagination. Can't wait to get one of those starter kits and build something!
Thanks, we definitely will, it’s already being set up with the various authorities. We should be all ready to go by the end of Feb. In the meantime you absolutely still can purchase from us, there is just a small extra cost. Remember, there’s no import duty on carbon anyway so the only extra cost compared to pre-Brexit is currently around 13 euros or 2.5% 👍.
@@easycompositestv i just want to have it "easy". btw this is stiffest and lightest ak buttstock iv ever had. made with ec materials and tutorials i.imgur.com/aQCUDtb.jpg :)
I'm pleased and amazed for what you have done. I'm into 3d printing and this is so usefull. I'd be delighted if you could make a video where it can be added some threaded inserts. I think that they must be placed and fixed before, laying up or infusing it. Thanks for share tour knowledge. Because of your videos I'm so interested in composites and its fabrication.
You guys make some pretty awesome projects. I work building parts for the rv industry and really wished we had demand for some of the higher end composites. It would be nice to have the challenge.
Wonderful video! Super informative. About 12 years ago I started learning composites manufacturing. This would have been such an amazing resource to have.
I just noticed that the Alex in this video is the same Alex whose lifeboat conversion videos I've been watching lately! The sleds turned out really nice looking. I hope to see more of them from his end. :)
Thanks for your videos! I took a lot of information about laminating and vacuum infusion from them! I even started my youtube channel about composites!) And it's really great to see this process again after trying it. Now I can see so much more interesting details. And special thanks for information about cutting kevlar, I had some issues with edges, now I will try to fix them.
Hey Paul. This tutorial is amazing. Thanks for sharing this with us! I have a quick question. What if there is a place where the resin didn't reach? Not because of leakage but for example because of a wrong setting of the resin hoses or so. Is there a way to fix that and save the part? Thanks man!
Hi Paulo, yes, you can often recover a situation like that or at least make it a bit better. It’s a bit of a messy process but you can ‘graft’ a new resin inlet and vacuum line, in situ. It’s difficult to explain but maybe I could do a short demo at some point.
I learned some crucial info in this, especially the existence of that sticky spray and two of those cloths. But I think that its a lot of work to go to to save a quart of epoxy over just rolling on. Finally, admit it- those are just bath tubs. You can only fool some of us!
That's awesome explained will you make another indepth video with vacuum infusion but on a kayak covering deck and hull joint and seam doing that will be super
All you videos are fn awesome, but this one is both a perfect segue and so detailed in what to do too not screw projects up. It’s real good to be able to follow and have someone who you can trust... mistakes are pricey in this field ha! 🇦🇺🤜🏼🤛🏼😎🍀🍀🍀🤓
If you make it 6ft long it can double as an emergency shelter. If that adds extra material then make up for it by making it skinnier. If you line it with millimeter-thin insulation, you now have a windproof, coldproof shelter 😊
What kind of temporary adhesive can I use in laminating fiber glass over wood? In certain awkward shapes I find very difficult to maintain the fiber in position while I'm applying resin.
Thanks, yes, agreed. It's actually quite limiting how much you can learn from just seeing the last stage of an infusion without understanding any of the 'why'. Glad you enjoyed the video.
Nice to see this technique demonstrated and beautifull part. Excellent video quality too. But I am a bit shocked by the immense amount of waste that is produced by this technique. All that plastic and breather material and epoxy that does NOT end up in the product but in the bin. Not suitable for recycling either because it is contaminated with epoxy. In comparison, it seems to me a more low-tech manual lay-up and wetting with a brush and roller would be much more efficient.
It's true to say that composites production isn't the lightest on plastics, but often release film and vacuum bags can be part or totally salvaged for another use. Also, infusion is pretty light on resin compared with wet lay or normal vacuum, as with the latter you'll end up squeezing and rolling plenty of excess resin from the edges which is wasted, or into a breather layer. It's also true that the fact peel ply is saturated with resin and thereafter has to be binned is galling, but it's hard to avoid. You can also look longer term - perhaps a composite part might perform for years and years with nearly no maintenance. A comparable wooden/metal part might need regular repainting or protection from the elements. Hypothetical, but you get the point.
Isn't that pink stuff pored in the cup that slime from Ghostbusters 2? Do not play music while the gel coat is drying. Also, do not yell curse words while the gel coat is drying.
Man oh man, resin infusion looks so complicated. So many small steps require attention. There is got to be a way to make it suitable for the industry tooling - machines, robots (yet for small scale projects)
In large scale production the resin transfer moulding process is used more commonly but it requires specialist, expensive tooling and equipment beyond what is reasonable for the DIY or small business user. Hence the infusion process works very well. Its not that complicated broken down into steps. The key with infusion (and many composite processes) is to follow the order systematically and adhere to it. Do not move to the next step until you have completed the one before. Especially the case when vacuum bagging to not move onto the infusion until you have a good leak tested leak free bag.
Hi Robert, it was more than considered; we did a whole video about it. Please check out the video which comes before this in the series! The runners themselves are fixed on after but.... spoiler alert.... graphite didn't help in this situation.
Thanks for the video. As always very informative. Thanks for pointing out all the details and thought-processes that come with experience. I've watched a lot of tutorials and I'm always pleased to discover more that I hadn't seen / considered! Just wishing you had few USA outlets.
is it possible to make a box out of carbon fibre without any holes? ive been looking at car parts made in carbon fbre and they all seem to be full structures with no holes to vacum form from the inside. im a bit confused
Excellent video guys, and very well explained and delivered as usual. My latest order has just arrived, and I'm sure you'll be taking much more of my money in the future 😂 Keep up the good work
Awesome explanation of the infusion process! Your videos are a great resource. I still disagree with you about clamping off the vacuum right after infusion - but its hard to argue with the outcome! There’s always room for more right answers. Your pre-feeding resin to the clamps trick is a great idea. Thank you!
Hi, thank you for your vids on here, they are really good! I’m a boat builder and have intermittent sessions of infusing components and the like. I’m always picking up little gems from both your videos and the comments below! Like the guy above, I can’t get my head round turning off the vac once the resin’s through. In a perfect world it obviously works as you’ve proved but I simply don’t trust my ability to get it perfect 😂 I have a more Heath Robinson type catch pot made from 6” waste pipe so I’m not too bothered about replacing it if I get a bit of resin through! Again, thank you for the great videos 👍🙂
another great video! in the meantime i have made a number of project with your materials and I have to say they are the best! all worked out so far excellent. please also check my channel with big number of videos showing my projects kind regards Alex
Hi Alexander, thanks very much for your comments and your continued support and custom. Your videos are great, the rudder project is fascinating and the end result is very professional. It would be great to put some pages together about your projects for the customer gallery on easycomposites.co.uk, we could like to your UA-cam and your project can inspire other customers. If you're interested, please get in touch with our Marketing Manager Becky; becky@easycomposites.co.uk
I love your videos. They are some of the best for composites. Would it be possible to use this process to make a long tube? I'm rather space constrained here. Your input is appreciated. Thanks again.
Tubes can be infused as long as the diameter is big enough to be practical to lay up. You will likely need spray tack to hold everything in place vertically. Also you will need careful planning of the infusion consumables so that the resin actually flows on all sides of the tube.
Generally-speaking, do the molds being used for resin infusion (or simply vac-bagging) need to be rigid, or can a silicon mold with a rigid mother mold be used? For instance, if I have a relatively thick silicone rubber mold in a fiberglass mother I use for hand layup, could that be used? I'm wondering if pulling vacuum could noticeably deform the part, especially if the rubber wasn't fully degassed and more than likely has air entrapment. Truth be told, I'd rather spend time on my stack-up and prep than tapping glass, especially if my final product is of better quality and less heavy.
Hi Thomas, we have not seen silicone moulds for vacuum bagging processes like infusion. The flex is likely to cause issues with inconsistent surface finish and part distortion.
By "Bondable for up to 24 hours" do you mean a successful epoxy resin infusion will be successful "up to" this amount of time? I assume if you go over that time the gc50 Gelcoat will be a solid separate sheet that won't attach the resin infused core materials?
yes the longer you leave it the lower the bond strength. So up to 24 hours you will get adequate bond strength between the materials. Over 24 hours you risk delamination.
You guys delivered on this video! Great production quality, and the parts turned out great too. Keep up the excellent work. We've enjoyed following you guys.

Very small items are hard to infuse. It may have been made in 2 parts or used a multipart mould to make things easier.

I bet those Americas Cup foiling boats are built by people just like this
Resin infusion has been used for years to make large composite components, so given their size, it's highly likely that they use this exact process.
Hi, i work with infusions myself, bigger parts tho, and we are having some trouble, i have a question for you, is siphoning of the resin not an issue for you, as your source is above your inlets? we want to move the source above the inlets, because our infusiion is going to slow, but the engineers are afraid of siphoning
Not an issue for us on this scale of work. As said, ensuring the resin pot is level or above can ensure you don’t get too many issues like that.
Did you use membrane? Thank you.
Hi Basak, no we just used standard infusion mesh
Sir, i have two part's of full carbon catamaran rc boat and i dont know how to joint them, do you have any solution???
Carbon tape over the joint will add strength.
Why would half the distance be 4 times quicker?
It's only a rough estimation but the speed of resin flow is approximately exponential, hence halving the distance will reduce the time by about 4.
The tape will stick where the easy-release is applied? No problems?
Yes, the tape uses a silicone adhesive which holds nicely even on an Easy-Lease'd surface

Please make a badminton Racket using high modulus graphite
Was mixing graphite powder into the gel-coat on the bottom and runners considered? It gives a great improvement in durability and friction reduction.
Hi Robert, it was more than considered; we did a whole video about it. Please check out the video which comes before this in the series! The runners themselves are fixed on after but.... spoiler alert.... graphite didn't help in this situation.
Unbelievable quality, thanks for taking us along on this remarkable journey. I have learned so much. Thanks again!
Appreciate the comment, I'm glad you managed to learn something new :D
Thanks for the video. As always very informative. Thanks for pointing out all the details and thought-processes that come with experience. I've watched a lot of tutorials and I'm always pleased to discover more that I hadn't seen / considered! Just wishing you had few USA outlets.
Thanks for the feedback Paul, we really will be getting something good together for our US customers/followers.
is it possible to make a box out of carbon fibre without any holes? ive been looking at car parts made in carbon fbre and they all seem to be full structures with no holes to vacum form from the inside. im a bit confused
Those parts will be made in split moulds and then joined together
Excellent video guys, and very well explained and delivered as usual. My latest order has just arrived, and I'm sure you'll be taking much more of my money in the future 😂
Keep up the good work
Thank you Gary; much appreciated.

hello! I want to make a box using carbon fiber and I want the inner surface smooth. how to design the mold?
If you just want the inside smooth, you would make the mould as a male mould.
Awesome explanation of the infusion process! Your videos are a great resource.
I still disagree with you about clamping off the vacuum right after infusion - but its hard to argue with the outcome! There’s always room for more right answers.
Your pre-feeding resin to the clamps trick is a great idea. Thank you!
Personal choice which method you choose or find works best for you. Leaving the pump running is fine when you have a decent resin break.
Hi, thank you for your vids on here, they are really good! I’m a boat builder and have intermittent sessions of infusing components and the like. I’m always picking up little gems from both your videos and the comments below!
Like the guy above, I can’t get my head round turning off the vac once the resin’s through. In a perfect world it obviously works as you’ve proved but I simply don’t trust my ability to get it perfect 😂 I have a more Heath Robinson type catch pot made from 6” waste pipe so I’m not too bothered about replacing it if I get a bit of resin through!
Again, thank you for the great videos 👍🙂
bro's bee's knees
another great video! in the meantime i have made a number of project with your materials and I have to say they are the best! all worked out so far excellent. please also check my channel with big number of videos showing my projects kind regards Alex
Hi Alexander, thanks very much for your comments and your continued support and custom. Your videos are great, the rudder project is fascinating and the end result is very professional. It would be great to put some pages together about your projects for the customer gallery on easycomposites.co.uk, we could like to your UA-cam and your project can inspire other customers. If you're interested, please get in touch with our Marketing Manager Becky; becky@easycomposites.co.uk
Thanks nice explanation.
Thanks for watching and taking the time to comment.
How did you mark up the cut line. Did you mark heights at intervals and made a best fit line with the tape?
It was measured and marked prior to cutting the carbon.
off topic but does anyone know more about that dark ice project?
I love your videos. They are some of the best for composites. Would it be possible to use this process to make a long tube? I'm rather space constrained here. Your input is appreciated. Thanks again.
Tubes can be infused as long as the diameter is big enough to be practical to lay up. You will likely need spray tack to hold everything in place vertically. Also you will need careful planning of the infusion consumables so that the resin actually flows on all sides of the tube.
Generally-speaking, do the molds being used for resin infusion (or simply vac-bagging) need to be rigid, or can a silicon mold with a rigid mother mold be used?
For instance, if I have a relatively thick silicone rubber mold in a fiberglass mother I use for hand layup, could that be used? I'm wondering if pulling vacuum could noticeably deform the part, especially if the rubber wasn't fully degassed and more than likely has air entrapment.
Truth be told, I'd rather spend time on my stack-up and prep than tapping glass, especially if my final product is of better quality and less heavy.
Hi Thomas, we have not seen silicone moulds for vacuum bagging processes like infusion. The flex is likely to cause issues with inconsistent surface finish and part distortion.
By "Bondable for up to 24 hours" do you mean a successful epoxy resin infusion will be successful "up to" this amount of time? I assume if you go over that time the gc50 Gelcoat will be a solid separate sheet that won't attach the resin infused core materials?
yes the longer you leave it the lower the bond strength. So up to 24 hours you will get adequate bond strength between the materials. Over 24 hours you risk delamination.
One of my problems while infusion is, when I have more than one mould parts the screws. Most of them got full of resin and it really hard to open them
Release coat the threads with a liquid release agent or seal around them so the resin does not contact the bolts/screws directly.
Thanks for the very informative video! My masters thesis has to do with resin infusion and this gave me a really good overview of the process.
Hi Clara, I'm glad that this was useful in your research!
I'm glad that now, if I ever had to build an indestructible Arctic ice sledge, I would know how!
You never know when it might prove useful!!
