Thanks, guys. It's been fun. I'm quite fond of the Dore Westbury, even though it's a bit of an old crock and the round column (which goes down through a hole in the benchtop) causes problems. First, to raise/lower the head, you have to unclamp the column at the bottom, and jack the column up on its screw thread using the round nut with tommy bar holes in it. This leaves the head free to swing in an arc, so all registration is lost. Changing from a long drill to a short milling cutter sometimes ends with a lot of resetting. I think this applies to most round column machines. Secondly, you can't be too ambitious with cuts, because lack of rigidity in the column (which is a thick-walled tube) can cause problems if the head is particularly high. I've read that filling hollow columns with epoxy and granite chips can help. Or maybe I could stiffen it up by cramming it full of the blue pills the inhabitants of my spam box are so anxious I should buy.... Andy |

Very nice retrofit of an old mill. Almost looks like it belongs on there. Bernd |
