Advice on ballscrew mounts for epoxy granite rebuild

[Nealieboyee]

An alternative could be to fix thick (>25mm) blocks of ali to the ends of the raised sides and screw your BK's into the edges of these? - that way you could have some adjustment. If you already have a working machine making them square shouldn't be too difficult.

Interesting idea. Problem is the ballscrew isn't long enough to allow the bearing blocks to reach each end of the raised sides...

Could you not alter your mould to reduce the length of the raised sides relative to the base?

I could, but my linear rails run the full length of the raised sides. I'd have to shorten them and reduce my cutting area along Y axis.
