Not to hijack this but I pretty much do it the same. I chuck up the gun drill in the headstock and start the hole with a short hole the same diameter as the gun drill, mount the stock blank against the tailstock center and push it into the the gun drill. I only go about half way, clear out the chips often and turn the stock around to finish. It never ceases to amaze me how the holes meet in the middle. The secret is in the gun drill, I make my own with a piece of drill rod. For the head of the screw, oversize, I have a 7/8" twist drill, 1/2" shank, with a pilot ground to the tip to match the gun drill.
