Andrew.....couple of quick questions......
First of the pics have clarified what you are doing.....good clear pics.
1. The linear bearings.....now I know what they are......very interesting system....I could use them in another application......how did you find them? Who would retail such bearings? I gather they are stainless steel?
2. Having an aluminium table......I gather you are not contemplating having vacuum in the future? If so are you going to cut out inlet holes into the ally deck?
Cheers
