Hubert, Worry not your old gray head, I frequently get Al and Alan mixed up as to who sent me emails. About that sure fire Atlas method of boring headstocks. My original 10 inch model worked perfectly, but the 12 inch "raised" model is skewed a bit off centre to the extent of about .001" per inch of travel. Other owners of this 12" model have also experieiced this identical problem so I wonder if Atlas did not try to make an adapter for the 10" boring head and got an error built into it in the process. Jesse in sunny/cloudy Troy. (I don't know what it outside as the sun is not yet up here while you are probably sitting down to your noon meal right now.) Hi Jesse I was all mixed up, and attributed your comment regarding the Atlas boring device to Al Messer. Please see my reply to him! Sorry!! Cast iron dust has a delightful taste! I am trying to persuade my wife to add it to her apple pies as a seasoning! Cheers from Hubert in Sunny St Albans. MODEL ENGINEERING DISCUSSION LIST.
