The Z axis looks like it could be converted by using a new top plate/bearing holder with a stepper/belt arrangement essentially strapped to the back of the column and abandon the "differential/bevelled gears" from the original?
Regarding the spindle it is the 2.2Kw W.C. I did try it at 5K but was happier with 5.5K I have my spindle set up so that it won't go down past 3.3K I cut the slot with no issues.
I suspect that all beds are different underneath so the clearance will differ. I will post when I get the x screw in place but I have to get them first. ..Clive

Excellent (starts looking at the budget for earlier purchase :) ).
I'll have to play with my WC 2.2Kw on my router also given your experience and see what can be achieved, though it will have to wait until I have my rotary axis working.

Not quite sure what you mean by that, The flanged boss I am using is to enable me to use the original end plates on the X bed by machining the stub off then boring the 40 mill hole out to 42mm then the the new boss can be fitted with the bearings offset by the 3mm I need to get the screw in.
The flange is in the centre of the bearing housing ie stub both ends.
Do you have a link to that screwed nut? ..CliveLast edited by Clive S; 13-06-2014 at 02:19 PM. Reason: add text

It's one from Zapp, if you look on the ball screw page it's down the bottom.
I presume that you're using the standard flanged ballnut like the below?
I was going to see if I could get away with one i could screw in to a 25mm (or whatever width) piece of steel that will replace the tapped existing nut.

This in the inside of the front of my mill, was thinking of opening the hole where the indicator goes through the bottom, rap it for a 1605 screwed ballnut and use a 1605 ballscrew with custom bearing ends.

Would two singles screwed into each side of the plate/bracket be ok?

Hi Jonathan
.
Can you explain in short words for an old duffer like me how a double nut works?
.
My guess is that there are "tensioned" in opposite directions against each other and therefore cancel out any play no matter which direction of rotation is used (can't quite visualise how though).
.
Cheers
