I started my build about three years ago. I haven't touched in two.I bought plans from data cut, i feel it is a real good design. I have just about all of the cast aluminum part done. I went to get a quote from a local bearing store and part number 2da-12-JOBL36 costs about $2500. Thats way more than i want to spend on the y axis. Is anyone out there building this machine? Haas anyone out there come up with a different way of completing this part of the build? Thank you in advance for all your help.
