re:Re: making ball nuts

Jack,

It's a "what you get for what you spend" proposition. You make some
good counter points(see below). It's also a "which would you rather
spend" situation. So, I'll go back to my initial response, "If you
can contemplate this, you can prob'ly pull it off..." Good luck, and
let us know how you do.

Ballendo

P.S. Have you considered a 2 nut "Moglice" solution?? This would be
really easy,and just may hit the "good enough, long enough" mark you
seem to be aiming for!

Like I keep saying, the trick is knowing what YOU want!

Repeat above response :-)

Prob'ly doesn't care much 'bout POSITION, tho, or repeatability

This just confirms my initial reaction. YOU could do this! Again, let
us know whatcha learn.
