Thinking about my own small Astra drill and re-reading Jim Whetren's description led me to a slightly simplified version: The vice is free to slide fore and aft and is instantly clamped by the knob under the table: In my version the clamping pressure is applied by the large washer and I have adopted Rod's suggestion of knurled top hat nuts.

2805 forum posts 219 photos	Neil: Whilst not claiming eagle eyes I did,of course, notice the slip; it made no difference in my case since I had decided to go with a large washer rather than the pressure bar used by Rod. I also dispensed with his brass washer, using moly grease instead. Incidentally, the hand knob was salvaged from an old office chair.
