i have the Data-cut plans here , and just about to start putting it all together , but at a first glance it's certianly well thought out and the plans are quite comprensive , and their is quite some scope to modifying as you go using it as a guide if need be , if i had a critisism it would be in the y axis round rails been hung underneath the table instead of all the weight being in a downward direction onto the rails if you understand , the weight would seem to be carried on the edges of the bearings at the top of the rail , so i could see some wear occuring over time , but of course this is just my interpretation and may be totaly wrong of course .
it's fine if you have access to a mill & also can get the aluminium part's ( the drawings are supplied to send out for quotes & for them to make gcode from ) made would make for a nice machine , or you need to have someone cut them for you.
