At this point I realised I needed a hole in each leg to take the threaded rod that drives the Y axis. No problem, some careful meassuring and drilling and presto. But now I realise my previous tightening of the bearings in place on the Y axis had left the central hole not quite central.
I ordered some new bolts with allen key heads, and some nylon insert nuts. The idea being that I’d get more torque on my tightening, higher locking force and better resistance to coming loose.
For some time I’ve toyed with the idea of building my own cnc router, or perhaps a 3d printer. The idea, of having a tool which allows me to fabricate parts using a computer to control the process, is pretty compelling.
