    Fixture plate to hold parts for powder coat oven cure

    I made this plate to hold specific parts from my 1957 Chevy truck front spindle assembly.
    My oven is not tall enough to hang the parts from. I have not used this yet, but when it dries off today will give it a try.

There's the brake pedal rod, clutch pedal rod, a shock absorber mount, U-bolt spacer, and some sheet metal dust shields. I'm using gloss black from a random eBay seller. 380F@15 minutes.

    I've not done a lot of powder coating, but so far I've not had issues with oil or other surface anomalies. These are sand blasted with white silica fine sand, then just washed with spray engine starter fluid to remove the sand and rust dust.

    Here are the results of today's painting effort:

    Fixture plate to hold parts for powder coat oven cure-img_20190820_130158.jpgHere I've applied the 2nd coat of powder to the side I missed, electrostatic attraction has limited success.
    Fixture plate to hold parts for powder coat oven cure-img_20190820_145202.jpgThis was after the 3rd coating, as the second one, I thought it had cooled enough, and I left imprints in the surface, along with little hairs from the hot pad I was using. Also DO NOT USE WAX PAPER, it got stuck to the part. So I applied a very thick coat of powder, and I used Teflon plumber tape where it touches the plate, this worked well.

    Lesson learned, let things cool down to where you can handle them with bare hands.
    I also need to get some high temp tape and silicon plugs to mask off holes and such.

    Posting from my phone so no link, but there’s an Instructables entry where someone turned an old 4-drawer file cabinet into a powder coating oven. As I recall he was using it for bike frame parts and such.

    I see there is a subforum here that has several oven builds. I'd like to be able to do something as big as a large truck rim. But then I'd want to do a whole fender or hood, or auto chassis in powder coat. I think some of these are done with radiant heat.
    It's been a long time since I did any spray painting, but I recall always trying to put too much on, and dealing with runs. I'm at a stage with the truck that I need to separate spot welded body assemblies on the truck cab, as major salt rot has to be removed. Getting paint back on unpainted hidden surfaces will be something to figure out.
