I’m about to print a form 1 ftn.5 rimfire can and I’d like to go ahead and do it with PPS-CF so that I can confidently dump rounds out of a pistol without worrying about it effecting the can. I know it probably sounds like overkill for rimfire but I have friends that aren’t believers so I really want to give this it’s best shot at heat resistance. I have a Qidi Plus4 so it’s more than capable of high temp printing. My question is, I’ve never done anything annealed so how do you anneal PPS-CF? My work does powder coating so we have a spare kitchen oven laying around for small parts so I’d love to find a way to just toss it in there for a 10 hour shift but I’m worried about if that’s risky because of the radiation off the elements. Can I wrap it in tin foil to block radiation or do I need to do something like fill a pan with sand to insulate it?
Back when I used PPS-CF, sand was my go-to for annealing—so much so that I still default to it today for every annealing. But that’s a tale for another day.
