That became obvious when I made a milling vise       attachment in night school for my smaller lathe. It has no carriage hold       downs in front and the rear ones are out of sight. The fix would be bolts       with two heads.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
