I forgot to mention, we drilled the through-bolt hole for the Martini in class. The same way that I always do it, halfway from each end on the lathe. The quarter-flute deep hole drill runs straight and true and when we ran it all the way through the hole was right down the middle with no binding at all.
It came out perfectly and we counter bored it with this bench made, floating pilot counter bore.
It gets a bit tense when drilling so no one thought to get any pictures.
That was the first time we ever drilled a through-bolt hole in class and everyone as impressed. I know I always am!
