I don't know if this would work. I would probably oil up a stud or bolt and then put jb weld all over it and insert it and mash it down till it was stuck in as far as I wanted it to go. clean up any extra around the hole to minimize how much I would have to file off later once it hardened.

if the oil works as it should you could then pull the bolt out and have it already threaded for you.

I might even cut a small lip inside for something the jb weld could hold on to better.

but since you know feets, I might see if he could cut it nicely and press a plug in and cut new threads.
