I got my kit in early July at the beginning of a month of vacation. It was all supposed to be done by now...right! I have the woodwork done, primed and painted and am starting out on the mechanical stuff. I sealed the MDF with Duratec sealer, which works great, and finished with car primer and paint. I have a HobbyCNC controller, MSC 1/2x10 2-start lead screws, DumpsterCNC delrin nuts and anti-backlash clamps. I got a lot of information from my friend John who built a Lion's Claw (prototype kit) router and learned from his experience. His is doing good work now with his machine.
My only snag so far is with the nuts, for which I did not buy the right flange. Joe's blocks will take the square flange and it was probably mentioned in one of the threads but I never took the time to check the details. So I had to put the proverbial round peg in the square hole. Thankfully, I have a lathe and was able to pop the nut blocks into the 4 jaw chuck and bore them out. It remains to drill and tap some holes. I will make the holes in the flange bigger than required so that there is some adjustment to ensure that the nut is well aligned with the feed screw. My friend John insists that it is impossible to live a normal happy healthy fulfilling life without a lathe and I have come to agree with him. They are just so handy to get you out of a jam! Even a little 7x14 chinese mini-lathes are very useful for this sort of job, or making spacings, bushings or what have you. Of course once you get one you will end up wanting a mill too - great for cutting the slots for the mounting screws on the aluminum bearing holders - no filing for me!
This week I hope to finish the Z axis including installing the acme rod, then polish up the gas pipes and install them on the X and Y and assemble the gantry. It is really coming together.
