I decided to go a different route when cleaning up my collection. Instead of painting, I decided to try powder coating. So, here is one of my XL12s that I just finished. The process is so much faster and I really like the end result. The 2-tone was a real pain. Color is not really correct but, it's close enough for me. That light/medium metallic blue is hard to match with a stock color through my current supplier. I'm sure I could have something custom matched...I need to look into that. This is the color that I originally got to try on a couple of my c-series saws.
I used the vinyl coated decals. I tried to powder coat a clear over the vinyl coated decals and that was a HUGE mistake. I did try powder coating clear over the regular self adhesive decals on a stainless mug (as a test) and it worked fairly well. I had some curl-up on one of the decals but, I think that was my fault...too much touching on the edges. May try it again on a non-complex piece. Removing the powder coat is not fun. I reached out to Joe at Sugar Creek about getting decals in a high temp material. No response.
Thanks for the kind words. I'm pretty pleased with the end result. I learned a lot on this project. I've never powder coated anything before so, I'm still figuring things out. Initially, I had powder everywhere then I decided to build a mobile powder coating booth. The investment in equipment was not too bad. It will pay for itself in no time. I am kicking myself for not taking pictures during the process and assembly. On to the next one....decisions, decisions....
Looks super ! But if you don't mind sharing your secrets , how did you remove all the residue oils from the parts and what did you do for surface preparation ?
Sure, glad to share!
I scrubbed, cleaned and decreased the parts in simple green and any degreaser I had in my garage that would get the job done. Got in the corners with a pick to get the hard-to-reach stuff that you can't get with normal scrubbing. Same process you would use for preparing for paint. Brake cleaner works very well for a final rinse. Once the parts were 90-95% clean, I media blasted the parts, then washed them with dawn dish soap and hot water. Rinsed and allowed everything to completely dry. Then I out-gassed the parts. Put the parts in my powder coat oven at about 425-440 degrees for about 20-30 minutes or until I did not see any more oil/grease working it's way out of the metal. I out-gassed them a little higher than the cure temp specified on the powder that I was using. Some people say to out-gas for longer but, that time frame worked for me. You'd be surprised, even after thinking you got everything clean, how much more will ooze it's way out...and from areas you never thought there would be anything. The out-gassing is critical, otherwise you will get a oil/grease bubble in your finish when you go to bake/cure your powder. Once I out-gassed the part in the oven, removed it, let it cool down little bit and I cleaned it with acetone and let dry. On a couple parts, like the drive case and the started cover, I went through this process a couple times to make sure I got everything out. Once I was sure it was good to go, I shot the powder and baked/cured it.
I figured it out through a lot of reading and trial and error. Others may have a better or different way...this is the way I did it.

Wow.. That saw looks better then anything I have seen yet, Well done sir !! I too am in the process of trying powder coating. I have everything I need except the oven which I should have soon. And again I say thank you for sharing your process for cleaning and curing as this will surely help me when I begin. Did you get your powders form Prismatic ??
Homer Homelite: Thanks. Yep, I get all of my powders from Prismatic. Sometimes it's hard to determine the right color just by looking at them online. I just ordered a bunch of samples that I thought were close, then selected what I thought looked best. Sometimes it worked, sometimes not...trial and error. I don't think I'll ever go back to painting saws again. Look forward to seeing more of your saws!
Homer Homelite: Nope, no primer coat. The finish of the case material wasn't bad enough where I thought I would need a primer coat. If the finish would have been really rough or pitted, I probably would have but, I spent a lot of time on all of the surfaces to make sure everything was smooth with minimal imperfections. Just used the base powder color, then a powder clear.
