Hi,

I have a G0704 that I just finished converting to CNC and after testing the backlash found its far from ideal at 0.02"+ with the gibs slightly loose. If I remove all slop in the ways it turns into 0.04"+ so I plan to do a few things. I need a granite surface to work the gibs into shape(may lap ect later), purchase double ballnuts and maybe try repacking them with oversized balls and if that doesnt do it go for some C3 screws.

I may also add gearing for my steppers vs direct drive as they don't sound too smooth at low feed rates and all of my cuts will be made at 5-15 IPM.

After looking everywhere I can think of I only found single 1605 nuts. I would prefer to purchase from the US but I realize this may be impossible.
