[Hallicrafters] Powder coating experiences

Fri Jul 27 14:10:58 EDT 2007

 have a 9 cubic foot powder coating in the shop. 3' wide with double doors, 
2' high and 1.5' deep. Will go to 750 degrees, however most powder coating 
is done between 380 and 420 degrees.
When doing aluminum, I clean, bead blast if possible and treat with 
Alumaprep and alodine. Steel is cleaned similar, but etched with a Jasco 
phosphoric acid solution. Have never had any trouble with adhesion. Have 
done a bunch of aircraft parts, some car parts and a little bit of 
electronics.
One thing, powder coat isn't as tough as you think it is. Jasco Industrial 
paint stripper ($30 gallon at Home Depot) will roll the best of it right 
off.
Do I do work for other people? If they are willing to pay for the time it 
takes to clean the stuff up, yes. The material and bake in is the lesser 
part of the job. I have had people bring me stuff that they said was cleaned 
and I still clean it, as even a finger print after clean up can cause 
problems.
Cost of doing a Halli cabinet, say for a SX-101-------- $75-100 depending on 
condition, plus shipping. The shipping is the killer. Probably cheaper to 
have it done at home.
I have wrinkle in black and gray, most any other common color in both gloss 
and matt.
This is a simple but still exacting science, not for the sloppy or hurried.
