    PC Powder - Follow Their Instructions?

    Got my first bag of PC Powder today. Was a little surprised at the directions on the bag.

    Only 10 minutes? What's "Part Metal Temperature"?

    The "part" is the thing being powder coated. Once IT is at 400F, start a 10 minute countdown

    (1) When the powder coat turns to the melted state...then, time it for 10 minutes. Use a verified thermometer if the convection oven is not digital.


    (2) I've learned that a full tray takes 18 - 20 minutes total. So...I'll set the timer at 20 minutes on a cold oven full-O-boolits.
    Then the second batch will go for 15 minutes as everything is pre warmed from the first batch.

    (3) Confused.?.go to step one (1), read no further...

    It is important to confirm your oven is reaching the proper temperature.

    Like OS, I used 2 oven thermometers set in the middle of the shelf I bake on and adjusted the oven temperature until the 2 thermometers read 400*. then I checked the oven setting and marked the dial on one of my ovens and marked the other oven with the proper setting to achieve 400.

    if you line the floor of your oven with a heat retaining product (I used ceramic BBQ briquettes, some use fire brick and other pieces of metal, it will return to temperature faster after the door has been opened and a new tray of bollits inserted.

    I always preheat my oven and bake for 12 min with constant good outcomes. It wouldn't hurt to go 15 min, good insurance.

    I just went through oven temp issues. I didn't have a thermometer so I had to experiment. Here is the link

    I use that brand powder, I pre-heat and cook for 14/15 minutes, have great results. Some of their powders call for 15, so keep and eye on them. Key is when to powder starts to melt. Hard to tell some times.

    I go 13-14m total time in my pre heated oven. It takes 2-3m for the powder to start melting. So far so good.

    So I put my lead thermometer in my B&D convection oven. set at 450 deg. Put it on bake. 350 is the best I get.
    Add boolits. They cook around 300. After 20 min. I quench in water. They pass the smash test just fine.
    Maybe my *** Lyman lead thermometer is off????
    Thoughts?

    Have you ever stuck that *** Lyman lead thermometer in boiling water to see what it might say ?

    I am not sure a therm that is supposed to be submerged will read air temp?? Just buy a $5 oven therm, done.

    I always follow powder manufacturer instruction for coating, if it says 10 min, I leave it for 10-12min but no more, let it air cool no quenching. A PID really helps for both casting and powder coating, can use the same PID just have two probes, preheat oven to temperature with the PID and let it run at the exact temperature throughout whole process, it will give you the best results that way. Variation in temperature and procedures will give you variations in results, which means less precision in your bullets.
