I like the idea inherent in Richard's idea and question. Further I would ask what drilling speed of which drill bit type is most suitable for Dilignit type blocks. Polished bits, jobber bits, high spiral, low spiral and what speeds. I have a block I have to drill when I get back on my feet and can stand at a drill press so I have more than a passing interest in this subject. I have long lusted for a mortising tool thinking it could be used for a number of things, like unbushing keys? Newton
