Oh bum....! Have been thoroughly corrupted now having seen this set of videos http://buildyourcnc.com/blacktoe.aspx
Reckon I can do this build as it is very straightforward, also like the vee bearing rails.... Although I am somewhat shocked at the prices of the vee bearings, anyone tried bolting two bearings together and using the chamfers on the od between them as a vee?
Also, as mine will have a 48" y-axis, I am back to the idea of twin motors and leadscrews.. Sigh... Need to get on with it now...
Gonna start building next week..
