exactly! I posted earlier about removing the top element altogether due to part sizes and restrictions. If you don't mind waiting an extra few minutes and a little slower recovery it's pretty safe to take it out. I'd maybe try what Fireblade says and remove the bottom but re-wire so that the top element is the service provider and then make some sort of removable tray that you can slide into the oven. (a stanchion of some sort for the larger parts to be coated and then rest upon if you will). Then again... you can always get about 6 ovens together and blow the sides out of two, tops out of two, bottoms out of 3 and weld them all together for one really big oven,lol.
..... (see the lunacy you get from me when you make fun of my widgets? lol). Hope *some* of that helped..... Russ
