I understand that powder coating aluminum parts can severly reduce their strength (depending on the alloy and temperature used) due to the heating process. I don't have any references at hand but I would study this before coating strength critical aluminum parts.

I was told that cracks would not show by some but the APIA I used said it was alright. A year ago I had oil on the floor below my gear. I pulled the gear and with no trouble found the gear cracked at the top. Cleaned it off welded it and had the gear powder coated again. --- On Wed, 1/19/11, Mark <markweg...@charter.net> wrote:
