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.
The plate is 1/4" scrap (to me) aluminum from a 19" rack mount filler plate.
I machined the tips of 1/4"x20TPIx1-3/4" bolts to 60 degree point using a carbide threading tool.
The main brake shoe support plate
The left side steering link, and the brake pedal link (between the foot pedal rod and master cylinder).
Some parts done in a toaster oven. 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.
