Ok so yesterday I posted this

and I made up a new screw. Now today the OPPOSITE side has stripped. I have about 12-15 Lee six bangers, I've been using them for close to 30 years, so it's not like I'm abusing/overtightening them. I know how to treat aluminum molds. But what are the odds of this happening in the same mold???
So after looking things over, I think I have a defective mold. I notice that when the screws are tightened, they sit WAY below the surface of the mold bottom, much deeper than any of my other molds. The actual threaded portion for the screw is therefore a lot thinner than it is on all my other molds.
So, even though what I did yesterday was beautiful, and is working fine, it is only a matter of time before it fails again.
So, I see two options. I could make a much bigger screw, like a setscrew, that uses the full diameter of the screw entrance hole. Probably like a 1/4 or 5/16. Or, go down from the top, like my HM2 .30 caliber mold. The handle screws set under the sprue plate in the top surface.
