Master modder ZapWizard has completed work on version 3 of his home built powder coating gun. Powder coat is applied using air pressure to blow negatively charged thermoplastic particles onto a grounded metal surface. The metal part is then baked to make a hard finish. ZapWizard’s gun uses an air pistol with regulator at the bottom operating at 15 PSI. The powder is held in an acrylic kitchen canister with a reinforced seal. The final element is an ionizer element placed in front of the discharge nozzle. Version 2 had a trigger operated switch for the ionizer, but that was replaced with just a simple toggle.
