Re: Re: making ball nuts

Chris,

I don't think the "gothic arch' is the main point of this thread. I
believe any good machinist could crank this thread form out pretty
easily, given the specs.

A single point contact reduces load carrying capacity in a BIG way!
And increases overall size dramatically. Now, balls in a std. ACME...

What if we reconsider the STANDARD ballscrew alternatives? And
compare results/expense "across the board"? I suspect we'll find
another manufactured solution to fit our price/performance needs.

The question is changed. So the answers change, too!

Ballendo (enjoying this list :-) )

P.S. Chris, As long as it's a NEW design(or fits the "cheapie
sizes"), your clipped paragraph below sez it all!
