Well been getting some good cutting going (enough to require maintenance duty on the machine beyond normal clean up after a days work) and looking to do some upgrade work on the Wee Beastie.

Looking for input on the best method for upgrading to Ballscrews and also raising the Z axis while keeping the rigidity up (if not increasing it). I am looking at either Alli' plate or extrusions and would like input there on the Y/Z axis unit (going to raising to 100-125 mm travel to allow the addition of an A-axis to the unit [already have the unit]).

On the Ballscrew front what I am interested in information wise is input on how best to convert the unit I have (a Merchant Dice TR model) to Ballscrews. I have been looking at Zap and a few others and would like in put on the best method for setting up the bearings for the ballscrews and if it would be wise/possible to upgrade to 20mm ballscrew from the 16mm trapezoid screw that is currently there (this is on the X axis, on the Y and Z I plan to upgrade to increase rigidity a bit).

Still cutting and business is improving so things going well. Hope everyone else is having a great day and take care.
