[ARCHIVED THREAD] - heat treating part

Posted: 9/16/2005 3:04:23 PM EDT

after i put my reciever in the oven for 1 hour at 600 degrees, Am i supposed to put my hot receiver in cold water to cool it down, or do i just leave it to cool down on the table?

600 degrees for heat treat? I don't think that is hot enough. When I heat treat ejectors and fcg holes, I heat them to a straw yellow color, quench, then heat to blue and allow to air cool.

Plinkereye, you are referring to the entire receiver, right? And dalesimpson, what do you use to apply the heat, and do you then treat the whole receiver? And do you do this before or after the rails are welded in? So far I've only done 100%-receiver builds--

I apply the heat with a MAPP torch, propane is too cold to do a real good job. I harden the ejector and fcg holes only, and I do it after the rails are welded in place.

Ok, so whats the easiest way to heat treat a Tapco receiver? I dont have torches and stuff. I have a propane cooker though. So a oven is not hot enough? so after bending, i weld the rails on the receiver and then heat treat?
