My flying gantry machine

**progomez** · 21-09-2009

Ive picked up a cheap wood lathe with 4 jaw chuck off ebay so will try and make a ridge on the delrin nuts (once I figure out how to centre the nut)

I also decided to make a smaller 400/400/200 cnc and then in time buy one of the kits off ebay (from china) which has the supported rails and make a 4'by2' cnc.

Ive also joined a cnc course at my local college. Its shows how to manually program haas machines but also in time Im hoping to be able to use these machines to mill some parts out of alu.

To centre the nut you need a dial gauge and stand which can be got off ebay relatively cheaply. basically the trick is to adjust one pair of opposing jaws until rotating the chuck 180deg produces no offset, then repeat for the other pair.

Be careful not to crush the nut tho...
