And Life marches in....

While working on the design for the new machine, I am having to improve the current machine do to production requirements. Sooooooo......... I have a couple of questions. The machine I am working on improving on is a Marchant Dice A3 Trapezoidal screw driven model. I am working on improving the rigidity and milling speed. I am looking at a dumpsterCNC anti-backlash nut for the 12mm X axis and would like folks opinions on that idea. Drawing up a mounting bracket in ViaCAD v8 and wondering if 6mm (or 1/4") thick alli' will be thick enough to transfer the force down to the cross brace. Main reason for going this route is that while business is picking up I really need to be a bit tight on the expenses side of things (which is why upgrading this unit has become first priority instead of second).

I will post a jpeg of the drawing in a bit and could use any input you folks want to give.

Thanks ahead of time and hope to pay it back or forward sometime soon.
