Well I finally got a hold of somebody at Rockford Ball Screw that could help me out, I hope. I talked to Ryan T., and he told me that they could make me some custom rolled ball screws.
I would need to send him my original lead screws so that they can duplicate them, or send him a drawing. I think that I need disassemble my table to see if I can take some measurements. Then I'll e-mail it to Ryan to see what they can do.
He gave me a ball park figure of about $800 for a complete assembly including the yoke.
This is a lot cheaper than Elrod Machine's $1525 for a X&Y axis kit, though I do realize that Elrod's kit has .0005 per foot precision ball screws. I am not sure if Elrod's kit includes a yoke though. I e-mailed them some questions, but never got a reply.
It seems that alot of these companies want nothing to do with hobbyists, or "one-offers". Too bad, I bet that they lose a lot of potential revenue that way.
Anywho, I priced some raw (unmachined) rolled ball screw stock and single pre-loaded ball nuts and flanges through Nook Inustries, and recieved a quote for $520. That does not include a yoke, and would require me to machine the ends.
Now all I need to do is to figure out how to take this thing apart! Anybody got any suggestions?  |
