Just a quick note. I sandblasted the heck out of most of the parts shown in my posts. The trick to not warping the part is to slow down the air speed. I did alot of experimenting with sand blasting due to the huge amount of posts claiming total destruction of panels from heat. It is not the heat! The speed at which the sand hits the metal has to be slowed to a point that ti does not "peen" it. Sand being thrown at metal at a high rate of speed has the same effect as a whole bunch of little dudes beating on the panel with little dude hammers! I saw first hand what happens with high velocity sand blasting on metal. It warps from the "hammer effect" not heat.Food for thought.
