Powder Coating who's doing thier own?

[Rooster's 67]

I have been doing my own powder coating, if it fits into a standard oven. Who else has been doing their own and what kinda equipment you using?
particulars on the gun... i am using the non impressive Harbor Freight gun,
but getting my powders from Ohio Custom Coatings.
my oven is a CL special..$30

my question is who has made their own larger cure oven, i really would like to bake larger items like bumper size, maybe even a block or heads.
throw up pics of your custom oven and maybe some specs of construction.
I am playing with making a larger, taller oven, 1X4 angle frame 3X3X7tall lined inside with 18-20Ga sheet fiberglass insulation 4 inches thick, and sheet the outside in 18-20Ga a large door(one side). on casters with a rack to roll in and out. use the guts from my existing oven but use both elements instead of just one for efficient heating.
