I recently spent some time powder coating some of my unicycles. Here’s my Kris Holm 26″ Mountain Unicycle with a Schlumpf geared hub, 2.3″ tire, and the KH handlebar:

I powder coated the frame translucent purple, which first required a base of mock chrome:

The pedals I also did metallic red, taking the bearings out before baking them.

The spokes are also done; I taped them to a piece of aluminum that I cut out:

and then clamped it to another piece of aluminum with a few c-clamps and wired them (at an angle) to the oven rack. This allowed me to suspend them in the air to shoot the powder onto them, and also protect the threads. Bronson gave me the idea to use some type of clamp; my original idea was to tap about 10 holes in a piece of aluminum and thread them in; however, it would have taken forever to do the tapping (plus, I don’t have the right spoke tap).

Sparkly metallic red:

I also used metallic red over the black rim, and it turned out pretty cool:

Louise’s frame looks even better; a chrome metallic base, then a candy orange on top, and finally the metallic red on top:
