I am going to try the alum trick on a broken 6 32 tap in a .250 aluminum part, broken off flush and all the way to the surface on the other side, I ordered 8 ounces of it from ebay and I will give it the smoke test! I was out of spiral point 6 32's, and got in a hurry and tried a hand tap in the machine and of course it didnt work. I was wanting an excuse to try this method anyway, so we will see if it works firsthand.I may have heard of this years ago but I dont remember it?? but at my age there are a lot of things I dont remember and a lot of items that are lost and never found ha! There was a post on this a few days ago but it is now closed so I thought I would start a new thread. I will post here if all goes well, or if it doesnt go so well.

Here is a link to the Alum if anyone is interested
