Harbor Freight powdercoat system

About a year ago I saw a dirt cheap powder coat system in Harbor Freight, and bought it. Finally got around to using it..... This thing is cool. Works great. I bought 16 different colors of powder off of EBay for a total of $46 including freight, and I've been coating all kinds of things that are laying around the shop. I'm using a laboratory sample drying oven that is 4'x4' to bake the parts.(cost me $25 at a industrial auction) but a regular electric range or even a pizza oven would work. so far my total investment is just over a hundred bucks. My last trip to the coater was three times that.
I found that sand or glass bead blasting the parts is essential if you want to make the coating stick. Other than that it's pretty strait forward. just follow the flow out and cure times that come with each powder. Most of the parts that I've done I could not rattle can as cheap as the powder costs.
 
OK I get it. Pictures coming in the next day or so. All I've done is car parts so far
 
Here are a few parts that I coated for '66 A/C Cobra. I'll be doing a few more this weekend
 
Pics are a bit small, Jack, but you're moving in the right direction!

BTW, thanks for the feedback. \\:D/
 
I went to Harbor freight and used their search feature. I didnt find the powder coat system. Maybe its been dropped?
 
no it's still there. I looked too. Gotta look under the paint spraying supplies. I think it was about a 100 bucks for the kit.
 
Good. I'll look again. Might be just what I need for a few parts on my bikes.
Thanks for looking past my nose
 
I wanted to revive this old thread, as I've just purchased this system. I have a decent blasting cabinet at home, but it is currently loaded with glass beads. I read somewhere that you must use sand or walnuts for prep for powder coat. Something about the glass beads making too smooth of a surface for the powder. Does anyone know about this?

Madjack, you said you were using glass beads to blast. How is the durability of the powder coating you have done so far? Can you describe your prep process and the results you have achieved?
 
I haven't been totally pleased with my hi-temp paint on engine covers results (staining and rub off occurring already). Could ya powder coat engine covers? I just realized we have a powder coating place in town. Or maybe Lee can hook me up. ;-)
 
I was thinking about powdercoating engine covers too...and the only thing that would concern me about it is loss of heat transfer due to the coating..how heavy does it coat?? If its not bad i dont think that it would harm them to coat...i dunno that id mess around with powder coating the head tho..might be a little dangerous...
 
This thread has triggered my thinking since I haven’t been able to find a suitable paint to use on engine covers – the regular automotive urethane I used is starting to chip off (it’s not high heat paint anyway). I think powder coat would be the perfect material to use since it can handle high temperatures and is chemical resistant.

My understanding is that there are two main types of powder: polyester and urethane. Urethane is more durable from a corrosion durability standpoint but beyond that, I don’t know the pros and cons of the different materials.

I’ve worked with component part suppliers that did powder coat and sandblasting is not common except when the old finish needed to be removed first. Typically the parts are dipped in a phosphate solution to clean the metal and give it some tooth for the paint to adhere to.

I’m going to look into that Harbor Freight kit. Eastwood also sells low cost powder coat guns. Should be fun.

IIRC, the Harbor Freight kit was priced at around $100...but when I checked on the site today, it was down at $49.xx, so I ordered it quick snap. Sometimes their prices for the same items seem to jump around.

Not sure about the composition of the powder they sell, though. I will report back with results.

I looked at the Craftsman gun, but it appears to be a rebadged version of the Eastman no-compressor type gun. I figured the compressor type would give better results. It would be interesting to do a side-by-side comparison.

Eastman has good products. Craftsman is more likely rebranding Eastman products than the other way around. Most likely someone makes the powder coating guns for both of them. Sears doesn't make anything. They rebrand everything they sell. If you buy a Kenmore product it is most likely made by Westinghouse, HotPoint, etc.
