Surprisingly reasonable results from the first attempt, especially considering the setup is far from ideal- outside, no oil/water separator on the compressor, a 3D printed tribo gun from Lithuania, powder that arrived in a package that looked like a something the police would show off boasting of it’s street value and cured with a heat gun.

The tribo guns don’t use a high voltage generator, the powder runs through some Teflon strips that create the charge. It’s supposed to require a special powder, but my eBay special stuff seems to work fine.

Now I just need to build an oven that can fit a wheel in.
