Re: Powder Coat System from Sears?!?!

Chapter #2


Ok, we last left off with the part cooking in the toaster oven. After the 20 minutes were up I shut the oven off and took the pulley out and allowed it to cool. After it cooled off I unwired it from the rack.

This is how the front (faces the fan/radiator) of the pulley looks after the powder has cured. The powder is just slighly thicker than paint, you can still see the Ford part # stamped in the pulley.

This is the rear of the pulley (faces the motor).

This is the 6 slice "family size" toaster oven I used to do this. It is slightly larger that the normal toaster ovens. A nonfood use electric stove could be used also. I had to modify the toaster oven to allow the rack to hang, and I'll get into that in the next post.

[PIC #4]
Here's the complete powder coater laying on the garage floor. In the photo in the previous post you could only see the gun close up, this is the whole thing.

It has it's control box and all the cables coming out of it. The black cable leaving the left side near the silver post is the 110v power plug. The gray cable leaving the top is the trigger. When you're spraying and you want to charge the part you press this. The part is only charged as long as you hold the button in. The thin black cable is the ground wire with alligator clip. When the pulley was hanging from the oven rack I had this clamped to the rack. This is why you need metal wire to hang the parts from the rack, you need to make the ground and continue the electric circuit. The gun is the last thing all the way to the right (pointing at the GoJak). Just to the left of where the black cable enters the gun is where you hook the air line to it. It has a trigger to control the powder output. The powder container attaches underneath. The end of the gun has a metal tip that protudes from it that charges the powder particles as they leave the gun. They in turn get attracted to the grounded part.

Above the gun and to the left of the second GoJak is a container of powder. This is how Eastwoods and others ship the powder. Different sizes are available. Prices vary depending on container sizes and colors. They do occasionally have sales on the powders.
