I wonder how I’d go about fixing the other end. It has a floating bearing, it’s only held on by a sirclip, other end is designed to be fixed

Hi Malcolm, As you have probably gathered by now the Ends will need machining to fit the Fixed type bearing. However, this alone won't make a massive difference it's the screw speed that is Key.

I've seen parts available on a uk website CNC4YOU ... seems to be a lot cheaper than I've been advised here for screws and bearings. Anyone used these guys before?

You will buy the same stuff from China a lot cheaper than he sells them.! . . .Where do you think he buys them.?
China at the minute is on Holiday but when you have the design nailed down and know lengths etc then Email Fred here for a quote.
