Having been let down twice (no names) I urgently need someone to machine some 80mm dia spindle clamps in either alloy or HDPE to replace the 70mm dia, 18mm HDPE ones on this http://www.zenbotcnc.com/mounts/bosch-colt-mount & reposition them on the backplate to put the spindle at the correct height. Sadly there isn't enough material on the existing ones to open them out to 80mm dia. I don't have any drawings, but I'm sure there are some suitable somewhere on the site. Alternatively procure a ready-made mount and modify the backplate to suit, though this might be a little heavy.

I'll happily pay for materials/time/postage. PM me...
