On Powder coating.I have done powder coating for numerous parts on my Pietenpol and Corvairengine using the Eastwood gun (about $100) and is it a good little unit.Check out the video on Eastwood.com - very informative about the wholeprocess.My experience is that a powder coat layer "mill thickness" will be the sameOR LESS than as a spray on paint layer so crack detection is more colorrelated than powder vs. liquid paint.Some tips:-It is impossible to put a "thick coat" of powder on a part in one pass.The process is very much self leveling. If you try to put too much powderon the part, the excess "blows off" the part. Multiple coats could build upthe film thickness (such as a clear coat over a color coat). Done correctlyonly a single color application is needed.-Positive ventilation / filtered airflow is desired. The powder gun onlyuses a few PSI, but the powder is so light is floats everywhere, in alldirections. -I find using two (or more) pieces of wire to attach to a part to theNEGative side is better than just one - the negative field sets better withmultiple "wire" contact points rather than just a single. Luckily mostfitting have holes at each end so this is easy to do.- Parts like a cylinder will take a lot longer to "flow out" because theyare a huge heat sink. Small items will "flow out" in about 5 minutes.- For the long tube type pieces I will use the "electric hot stove and stovepipe" oven I saw posted on this list - was that submitted by Jack Textor?- I did not want to use a "kitchen oven" due to need for 220V in my garagewhich I don't have so I purchased a HUGE toaster oven. It's a HamiltonBeach unit for about $69 at Meijer's. The rough interior dimension are 12"w x 12" d by 7" tall. I was able to bake 4 Corvair cylinders at one time.I also powder coated the engine flywheel! Of course the numerous smallmetal parts can hang from the "racks" using some safety wire. I can fit 20or so small metal fittings at one time I like this setup very much. It's a lot of fun to watch a part go from a dull grey powder finish tosuper glossy "Kentucky Chrome" as the paint "flows out". Email me off list if you want some pictures.
