@delpn @rlisbona any chance there is an upcoming powder coat training? If not, would the best course of action be to attend the next metal shop committee meeting? Thanks in advance!

I too am interested in a class as I have a crash bar and powder Iâd like to use. Or if someone wants to use mine as a test piece Iâm good with that too, (itâll be hidden anyway) donât want it to rust and want to get it painted soon.
Hi Jeremy. Iâll be there tonight and Iâll run you through the process with your bar. If anyone else wants to join us just show up around 7pm. We arenât having official classes until we get the oven lightâs delivered and installed. As of now they are only ordered.

Thanks @Mrholthaus for the demo and for showing the outline of the upcoming powder coating class that is still being planned as the process is being sorted out.
I think the oven would definitely benefit from oven lights that you said weâre still waiting on and also determining why the oven wouldnât hold commanded temperature. For some reason, we had to set the desired temp higher than required by the application instructions to get oven to (kinda) hold the correct baking temp.
Overall, the demo went well and Iâm happy with the end results. The Prismatic Powder used was Desert Nite Black, Item: PWS-2859 - a black wrinkle finish.

The oven should hold a very steady temperature. What kind of variations were you seeing?
The powder called for 375F, so we set oven to 375F but noticed that it was âclicking-offâ any time the temp approached 375F. Seemed to settle mid 360s. We bumped temperature up to 385F and temp hovered just below 375F. The relays kept clicking off and on without reaching commanded temperature.
Thanks for the clarification. The controllers are supposed to be PID controlled so with the proper settings they should be fairly accurate. Usually, the default configuration works reasonably well but this sounds like something is off. Wild guess is the D is too high. Anyway, definitely an issue.
What are the dimensions of the booth filter that you guys measured the other night?
Filter is 20x25x4. MERV 8 or higher. Stock one is a MERV 8.
Lights came in. They have MOLEX connectors. Not sure if @artg_dms has any connectors lying around that will fit. We need to cut holes. Iâll look into it tomorrow.

If electronics doesnât have anything, I might. Send pictures next to a ruler for scale. Do these connectors end up in hot areas? Nylon is not very temp resistant. What kind of wire insulation is used?
Those look like AMP connectors. I think there are some in the Tanners loot, if they havenât been hauled off by the raiders. I may have some, Iâll dig.
how many do you need?
We have 4 lights so 4 of them
Iâll be in tomorrow. Where are the lights so I can see if what I have fits or not?
That looks like a decent test. Iâm just curious about the âbubblingâ? It almost looks like it has water on it.
Yeah it didnât turn out. Still experimenting. Those illusion colors are a bit tricky. I was testing masking, recoat, and multiple coats
