I had the bright idea today to hog out the majority of a 5" diameter blank with a 2 1/4" Forstner bit. The short sighted plan involved removing more material to reduce the wall thickness in some way. After successfully boring the hole I realized I couldn't come up with a way to proceed other than to make gradual scraping cuts on the inside with a skew. That's when the tenon (Yes, that's right John, not a recessed tenon but a real one) I made to chuck on the opposite end broke off. It wasn't that big of a deal because the piece just rolled off the lathe and I was not in the line of fire. So, was the bored hole a bad idea? If not, what is the proper way to reduce the wall thickness? Here are a couple of pics of the failed attempt.

PS I plan to work on some non-glued pieces of construction lumber tomorrow as suggested by Mr. Canfield.
