my build

Looking good, those beams look promising. I,ve got some similar ones that are also from a stair lift. Not sure I would of cut so much out of it tho.

I plan to mount the rails on the other side with the T-slots, why did you choose to mount them as you did?
It will be interesting to see how it performs, save me some R&D

Looks very good - always nice to see the machine move for the first time and do something useful!

hi
on my y axis i have been using 4 v groove bearings i bought on ebay
http://cgi.ebay.co.uk/V-Groove-CNC-R...Domain_3?hash=

i had a slight wobble at the cutter when cutting and tracked it down to the few mill play in these bearings , preloaded the bearings against the rail but could not eliminate the play, so today two 800mm supported rails and 4 bearings arrived from zapp, these are going to be a big improvement ....

who says scotsmen are mean , why buy proper rails when you can buy 4 v grooves for £26 .....
