Update,
I pulled the machine apart to check some measurements and found that my tables are a little shorter then the machine Jeff D. made the plans for. Not a big deal but I am glad I checked before ordering the ball screws.
As of tonight most of the parts are ordered... Ball screws, ball nuts, bearings, pulley's, belts, and a bit of aluminum that I did not have on hand.
I purchased the ball screws from linearmotion2008 on ebay and paid for the end machining for a whopping 24.00.
I am up to about 650.00 including shipping for all the parts except the servo's and controllers etc.
