Step 1: Clean Cog

You can do this with some elbow grease or you can get it media blasted. I got this done at the same time as a load of other stuff (see my V8 table Instructable), but it didnt come out great because it was so rusty.

I decided to get it acid dipped instead. This made it pitted but clean!

Step 2: Prime Cog

Step 3: Paint cog

I couldnt decide what colour to do it: black, grey or silver.

A friend suggested satin black, so I went with that and it was a good choice.

Felt the underside to stop it scratching any surfaces.

I just went to a hobby store and bought a sheet of sticky back felt.

It was as simple as cutting it out and sticking it to the bottom.

Step 5: Relax

You can use it as an ashtray, or as a coin holder; what ever you like!
