Gentlemen and Trolls I am in the final stages of reassembling a vast old flat-belt drilling machine (about 7' tall) and would appreciate some advice. The socket is 3MT and it will be mostly used for 1/2"-1" with the occasional foray up to 2". What range of quill speeds should I aim for and how many horses will the motor need. I have 3 phase. The machine carries no markings but is of massive and timeless design and the threads are metric. If anyone wishes I could stick a pic on my website. regards
