Fitting ball screws to Chester 16V

[Tom_Nelson]

Thanks for the advice,
I've ordered some chinese ballscrews on ebay and when they get here I'll figure a way to get them fitted. Closer to the time I'll cast around on this group for somebody near me with a mill. I tried looking for dimensioned drawings of the 1204 ball nuts but found 2 different sets of dimensions, so I guess it'll be better to have them in hand and measure up before going any further.

In the meantime I'm going to go ahead anyway and try making some delrin acme nuts, just to see how it works (I just enjoy trying new things). Whether they work or not won't really bother me since I've now committed to ball screws anyway.

Be careful when machining away the bed or base for clearence as it can release stress's and twist the bed/frame. Make sure you have plenty of meat left and not taking too much away.!

I had the same problem with my RF40 mill - I ended up modifying the ball screw housing with an angle grinder so that it would fit in the available space. The angle grinder was needed because the ball screw housing is hardened and I couldn't machine it with my mill.

With a modified ballscrew and a bit of machining on the mill bed - I managed to make it work !

Good day

12x4 low profile nuts shall be ok, (outer dia 24 mm). Clean the bed with acetone, and fix the nut with epoxy cast in.

Strong enough.
