I really need to buy one but that will have to wait until I move so was wondering if anyone had a lathe and could modify a few small components for me for a fee/cutting tools/beer/etc?

Just 5 small shafts that need turning down from 8 to 5mm at each end for bearings and 6 pulleys which need drilling out to 8mm for a large 3D printer.

You could try these guys if no luck. Really small manual machine shop. http://www.yell.com/biz/bristol-light-engineering-co-bristol-41475/
