I'm working out the design of my hobby/woodworking router...and I've come to the point where I really need to understand how I'm going to mount my ballscrews to the frame of the machine & to the gantry.
I read this thread:

And I really like Jeff's drawing of the bearing mount. But, I am not a machinist, and I don't own any tooling to either turn or thread the ballscrew. Nor do I have the capability to drill out an aluminum (or brass?) block, to act as the bearing plate.
So, McMaster has ballscrew end mounts -- but the darn things are $311 each for 5/8" Seems excessive...so I was wondering:
If I were to bring my 5/8" (or 3/4") ballscrews to a machine shop, how much do you think I'd pay to have the end step-turned down (like in Jeff's drawing), and then threaded for the retaining nut?
Also, what do you think they'd charge me for drilling out a couple of square blocks of aluminum, for the bearing plates?
I'm going to get in my truck and visit a couple of local shops to ask them directly, but I wanted to be armed with some guidance from anyone here who knows that business, first.
Say, anyone reading this who can do this and is near Dutchess County, NY...are you looking for a new friend? :cheers:
Thanks,
Chris
