Hi Guys, I am slowly (very slowly) getting the Bridgeport installed. The motor is now wired up and controllable, but still very noisy. Whilst cleaning things I re-discovered that the handle that locks the vertical movement of the knee is broken. In order to prepare for a repair I thought I would unscrew the locking rod, which passes from the front of the knee to the back where the gib strip is. I have turned it a number of revolutions, but it doesn't appear to be unscrewing. Does this lock work by screwing onto a little slug (brass?) which bears on the fixed, main casting? If not how does it operate? My manual although it shows an exploded view is not a lot of use in this area. Cheers, Roger Mason, in St. Agnes. MODEL ENGINEERING DISCUSSION LIST.
