That's not a bad idea. It is a frame attachment hole. I was looking at thread inserts and to get a 3/8-16 thread inside, the outside has to be about 9/16, I think that might be pushing the limits of material around the side of the hole that already has a chip out of it. I know where it's thin where the chip is is only the top part of the hole, and further down the hole is in the meat of the case and should hold fine. If a 7/16" hole in there fails, I will still have the option of going to an insert hopefully. The frame hole probably will need drilled to 7/16" also, correct? I like this idea... thank you.
