I'll bring this thread back up..
Paul, if you remember, I mentioned my old Canadian Dufferin Sneaky Pete with the stripped threads. I decided to try and fix it my self. Figured it would probably have cost me more to have it professionally repaired. Since I am a professional woodworker...
First, I needed to bore a larger hole to get rid of the worn out threads and allow for me to tap for new threads without running into any "dead air" from the old threads.

Mark the drill bit for depth.

Turn a maple plug and glue into place.

Now to the lathe to bore a new hole, smaller then the threads.

I don't have the proper lathe for this, but I was lucky and I have been doing this for many years. Time to clean it up and put it back into service.
Needs a new tip and a couple of tweaks, but I did break a rack with it and it's solid. Looking forward to putting it back in service.
