View Full Version : Powder Coating and Tolerances...

10-18-2015, 10:44 AM
I'm looking to have a shroud custom machined, and if Tim is unable to do the work when the time comes, I'm going to have to go to another machinist. With that in mind, I'm faced with a slight problem. The shroud will need to fit over a powder coated saber, and will need to be powder coated on the inside to get the look I'm going for. So, how much extra inner diameter do I need to give to allow for the two layers of powder coat?

Depends on the powder coating. The translucent PC coatings tend to be thinner than the textured or matte finish ones.

Most likely matte black and brilliant bronze on the inner hilt, and trans purple on the shroud

finding someone to anodize the inside instead of doing a PC would solve your problem

That's an interesting idea. Can you powder coat over anodizing? I could just get the whole shroud anodized, then slap a clear coat on the outside for protection...

I would do one or the other if you want colors to match. You can anodize at home in a fairly clean and safe way. I just finished anodizing my most recent build.

You can powder coat over anodizing. Anodizing is pretty durable, so clear coat may not be necessary (though it won't hurt anything). Keep in mind that anodizing does increase the size of parts by a very small amount. That usually doesn't come into play unless your tolerances are *very* tight though.
