- NEW BRAKE CALIPER VIDEO - SHORTER AND MORE CONCISE! • How To Powdercoat Brak...
Another rather lengthy video, but I cover the powder coating process and give some cool tips as well as the rebuilding of different types of brake calipers. I also explain the differences between types of calipers and how they work.
Music: www.bensound.c...
Some thing you might try is plugging the holes when you’re putting on the powder and then pull the plugs out before you put it in the oven. I promise you I’m not telling you how to do things but the powder lays good without leaving a edge
I've done it that way as well. These days, I rarely mask any of it. I just use carefully applied air to blow out the holes or carefully wipe with my finger.
Yes would like to see a run down and parts list you used to build your over. Great videos keep them up.
Vetterunner25 thanks! I will be doing a complete overhaul of the shed next month, so I'll make a separate, in depth video about just the oven.
I would definitely love to see how you did your powdercoating oven as well. Please share and great work!
Yep... Def need an oven build vid
👍
That powder coating oven 😍 do you have a video of how to make ? Save me a lot of time for projects
I did not do any video when I made it, but a few people have asked about it, so I will do a video rundown of how I built it. I don't know when, but it should be soon. Thanks for checking it out!!
I lightly put the bleeder valve in and carefully take it out once I coat them. You can just wipe the powder off the bleeder valves with a rag. I don’t use plugs either. I use the bolts about a turn in. It’s easier to just take out.
That is a great tip! I've done that in the past, but I found that removing the silicone plugs disturbs the part less than the removal of nuts and bolts. Either way is better than getting powder in the threads though, unless you plan to tap them anyway (like I did in the video)
Tiny Garage Fabrication I have never used plugs. I use the bolt or bleeder valve. Carefully remove it and cook away!
I just started using my hyper smooth today for the first time. I'm getting pretty significant leaking out of the attached Hopper. The one like you have. There is a note in the instructions it says I'm a leak may have to glue it up. Did you have the same issue? I don't yet have a booth and it seemed like just as much powder came out of the bottom is out of the front of the gun!
I can't remember if it was on the cup gun or the 'jug' hoppers that came with the unit, but I definitely had to glue something. A standard hot glue gun is all I used. Trust me though, the cup gun attachment is significantly better than the 'jug'. I don't know if you've seen it yet, but I have a booth build video that may give you some ideas to adopt for your own.
Excellent powder coating tips, thank you.
Thanks for watching! I have a whole Playlist called "Powder 101" where I give more tips and powercoat other types of items also.
Add another heating element to that oven , it will help ramp up temp so much faster ..also those threaded holes , if u getting blocked by plugs use foil paper in them 😀
I've got some calipers I need to coat. My process is pretty good at this point, except for knowing what I should and shouldn't coat. The calipers themselves are the calipers and brackets from the SN95 Mustang Cobras for my kit car. I know the bores have to be protected (or vacuumed out), and I should mask off the pin bosses, bleeders, and banjo bolt areas on the calipers themselves. However, what about on the caliper brackets? I know the bolt holes need to be plugged, but what about the machined mounting areas around the bracket bolt holes? How about the pin mounts and pad contact areas on the brackets? :(
Thanks...
So, you pointed out a lot of areas of concern, and great job noticing beforehand! While I'm not the foremost expert in the field, I firmly believe that machined areas on calipers, brackets, and wheels should not be coated, in any circumstances. A lot of shops will coat everything, and a lot of people will never see the issues. To me, I see the potential for the coating or paint to crack and fall out, thus making your bolts loose and now you're a danger to public safety. I mask all mating surfaces so that I can accurately torque things down and they will stay that way. That's how I recommend you do it, even though it may lead to some corrosion or discoloration where not coated. This is where some oil/grease/spray paint after assembly can go a long way.
Just use your best discretion as to what to coat and not to coat, based on the info you have and the outcome you desire. But remember to make a safe product in the end, because nobody deserves to die over shiny calipers.
Yeah, that's generally how I feel about it, but a lot of folks temm me I'm going overboard. The entire bore face and opposite face inside these calipers are machined, too. So are the caliper clip spots where the pads slide.
It's just a pain... Outgas, mask, blast, remove mask, clean again, plug or mask again, shoot, then remove plugs and mask if you can and bake, then remove what's left after. For calipers it's a ton of work. 🙁
can you make a video of how you made the huge oven I am really interested in making one of those for the same thing....I been doing it at a small scale but really could use one of those.
Absolutely! I'm rearranging my shop, so now is a great time to do this. I'll try to knock out a video this weekend.
well 3months and no video about oven 🤷🏼♂️
He’s promised to show how he made it multiple time and never has.
Subscribed! I like your DIY water trap. I made one that I still need to finish and start using. It has a large pipe that hold desiccant at the end of it. I figured out a tip for using plugs and not getting that build up around the edge. I use a longer plug and screw it in tight, but before it goes in the oven I unscrew the plug a couple turns. It cut down on the build up a lot for me.
Thanks! The copper trap works alright, and I'll keep it with this current compressor, but I got a larger compressor and I'm going to a refrigerated air drier.
I pull the plugs when I remember to do it, but I either forgot this time or used too short of plugs. Nice catch on that one.
I'll have another PC video out soon, I just did the entire front suspension on my wife's 67 Cougar.
@@tinygaragefab My fiancee has a real dryer for her automatic screen printing press. I just can't justify the cost of one for myself right now. You definitely need to do a rundown video of your homemade oven. I have a derelict electric oven in my side yard that I plan on cannibalizing for parts to build something similar. Yours is sick!
I was thinking of using a crown vic front suspension. It will be really wide for my 1952 F1. Jag front is the right width. It's hard to find one here in southern Utah. Not many in wrecking yards. They get crushed quickly. People just don't want parts says the junk yard, hard to sell. What years do they come under. I heard you say 1985 ish...
donald gibbs they are good from the mid '70s through '86 in the XJ6 & XJ12 and through about '92 in the XJS. But I agree, it's hard to find parts and the '03+ Crown Vic is way too wide for an F-1
Thank you! A guy in Idaho sells a narrowed cross-member. Another guy sells a complete kit that is narrowed. I would rather fab something that works and is the right width. Keeping factory parts for future fixes is key to me. Thanks again!
remember to only use silicone lube on any kind of rubber because grease swells rubber and causes binding.
Good video, its easier to seat caliper piston boot by installing first (slide over piston) and then push piston in.
Thanks! Some caliper pistons don't have the lips that a seal goes into, so its hit or miss on installation technique. Either way, I'll rebuild them all.
Ive been looking everywhere on how to hook up a gema gun to a columbia controller. Was it a difficult process? Plug and play? Thanks.
This is the gun that came with the controller, so unfortunately I don't have much info for you.
@@tinygaragefab Ok. In the video you state it’s a Gema gun. That’s why I was asking.
Planning on doing anything to your wheels? These turned out great!
I left the wheels black. I sold the truck about a year ago. Go through my videos and there are a couple vids of it completed.
It's it necessary to remove the handbrake mechanism from the caliper?
It depends on the caliper, I suppose. If any of the handbrake parts can melt/distort in the oven, then absolutely remove it. If it hinders installation, you might ruin the finish taking it apart and putting it back together. Lastly, the tolerances of the cable housing or whatever attaches to it...the powder may build up thick enough to get in the way of a smooth installation.
With all that said, I sometimes leave extra assemblies in place, but I usually remove them and coat each part independently.
Did you put a clear coat on top? I did mine with no clear coat and they are hard to keep clean.
Yes, these definitely got a clear coat. I used Clear Vision from Prismatic.
Very nice calipers now!! Nice job :)
Looking awesome
Can you please do a video on your oven and how you built it. Also how you wired/mounted the heating elements and how you control them
I will be making that video soon and adding it to my Powder 101 Playlist.
Tiny Garage Fabrication awesome! Thank you👍
Just use a kitchen oven
Can you fit a whole Dyna frame in a kitchen oven, @03dynawide ? Nope. I built this oven to do motorcycle and quad frames back when I built more bikes than cars.
Have you tried wet power coating.. more effective power transfer and to can touch up larger project that need objects rewarding to it which can be removed it a gate if all ready installed
I don't think that would suit my style. It would require 100% masking, and color (powder) changes would require way more time, effort, and materials.
What size of compressor are for sand blasting? Psi and cfm? Thanks in advance!
My compressor is an 80 gallon, 5hp 220v single phase. I think it is 24cfm at 90psi. Well, that's what I use now...the compressor in thus video is smaller and would run continuously while blasting. I blast at around 90psi, which is pretty aggressive, but saves a lot of time. I have multiple stages of moisture removal as well.
Why would you do a nice powder coat job and then use a c clamp, clamped to the body. 😔
Because powdercoat really is quite durable! As long as I'm careful (which I am) it won't scratch. No worries here.
Good work. Please advise where you got the oven and your powder and coating equipment. I am interested your powder coating work. Thanks.
I built the oven basically from scratch. I'll make a video shortly that goes over the whole thing. The powder gun is a Hyper Smooth from Columbia Coatings. And I get all my powders from Prismatic Powders.
I'll be shooting a "Do's and Don'ts" video on powdercoating soon as well. A LOT of youtubers are giving horrible advice and steering DIYers in the wrong direction. (Cameron Niemela and his brother, for example)
Add pvc pipe sleeve that slides on the support tube of your rack.
Thanks for the comment, though I'm not sure what you are suggesting. PVC going into the oven doesn't seem like an idea I'd fall in love with.
You should have use a small tubing and vacuumed out the powder from the holes
Since this video, I've designed and 3d printed different attachments for my vacuum to do just that. With different holes, I can add and remove suction as required.
Nice vid bud, im in a conundrum on weather to powder coat or paint (ultra high temp) my calipers for my next project.
I've seen that there is powders that are specifically for high temps or is it not necessary, whats your advice? Nice videos and channel, keep it up.
Renitent Entity I don't think that ultra high temps are an issue, provided you aren't building a full-on track car that could see extended extreme brake temps. Powders flow out (turn semi-liquid) around 250-300°. However, high brake temps affect rotors, but how much of that heat soaks through the pads and into the caliper body??
Many manufacturers (Wilwood, Brembo, etc) offer powdercoated calipers, so if the aftermarket supports it with their R&D money, it's good enough for me! Lol
Yeah I really like the idea of powder coating too because the finish comes out really nice. The brakes will take some substantial abuse to be honest, gonna get a bit toasty.
I'm leaning toward powder but will let you know how I get on, thanks for the advice.
I was wondering if some time you could detail the fluidized hopper? I have one I picked up with another GEMA unit and it is missing some parts and would love to see what some of the parts I am missing might look like.
Heck yeah! I'm tearing apart my Celica now and will be powdercoating a ton of stuff, so I'll sneak that in there and hit you up when I drop that video.
@@tinygaragefab Very much appreciated!!
How much does that oven run
How is that skat cabinet? I’m looking at buying a new one and there’s is one I’m looking at. It says 10-15cfm @80 and my compressor is 15.8@90psi. So will that work with this cabinet? How is the compressor work
So...its not bad, but definitely not great. With 10-15 cfm, your compressor will run non-stop. My 24.5cfm runs almost non stop at 80-90psi. The blast pattern is maybe dime to nickel size, so it's not a super fast system. And the media sticks to the "funnel" so a vibrating apparatus is HIGHLY recommended. I could make a whole video on the good/bad of mine...
Tiny Garage Fabrication i would be interested in watching it lol. I’m about 3 weeks away from a purchase so i would love to see a vid on it. But do u think my compressor Compressor
15.8cfm @ 90
16.4cfm @ 40
Would be able to do 4 rims with ease? What’s yr opinion? I’m just a back yard shop that powder coats but my biggest projects are 4 rims in a day.
I ran a 60 gallon Kobalt compressor from Lowes for a few years. It was rated about where yours is. It ran non-stop, but it got the job done.
Personally, I would not do 4 wheels in a day like this. It CAN be done, but it's not worth the frustration. Especially if you live somewhere humid. The compressor will send that humidity into the cabinet as water, which clogs the media and can flash rust steel that is being blasted.
Also, the vacuum that comes with these cabinets should not be used without a Dustopper or Dust Deputy at a minimum. The filter will completely clog in a matter of an hour or two, then you have no dust extraction, which compounds the frustration.
There is waaaaay too much gear needed for a "perfect" blasting setup.
Tiny Garage Fabrication any suggestions on what i need to do to make it better? Or a cabinet i should buy instead to work better for what i need with compressor i have?
@@bjputvain I have to say that overall, I am happy with my Skat Blast cabinet. I added an LED light to the top inside the cabinet, a small air vibrator to get the media moving, and a Dustopper between the cabinet and the vacuum. It works pretty damn good, but it is a little slow because it just doesn't have a large blast pattern.
It is an amazing upgrade from my old heavily modified Harbor Freight blast cabinet.
How did you build your powder coat oven
I've got a full oven build video coming soon, so stay tuned to my channel!
This is great
Thank you! This video is a bit long, but I didn't want to leave anything out of the process. I will be doing more powdercoat videos soon, and they will cover smaller sections and be a lot shorter, so stay tuned and drop comments on anything in particular you may have questions about!
