While I have bought some stuff from McMaster Carr, its more because they
may be the only ones stocking what I need. Either way their prices are
astoundingly high. Take a nook bronze nut for 1/2" 10 tpi ACME thread,
with a 3/4" OD, 11 tpi thread (IIRC) on the outside, so you can use two and
adjust easily for very low backlash. 8 or 9 years ago when I bought them
and a stick of black oxide coated, 1/2 10 tpi acme rod, those 3 pieces were
just south of $175. And UPS bent the bolt, about 1/8" in its length. I
straightened it as best I could and used it. I should have bought a
Chinese ball screw for about that money. A longer one for the lathe was
only $138 delivered to my front deck this past summer.
They may have it, but their search engine sucks, worst in the business and
if you do manage to find it, they are 2x to 4x too proud of it in the
$/item column.
When I paid nearly $80 for two timing belt pulleys for the same Z drive, I
expected a decent finish, and got what looked like sand castings I had to
finish boring to size. Consequently, M-C has been my source of last
resort, not my first goto place.
And maybe I'm just in a bad mood, its looking more & more as if I'll have
to find about 35 large for a new knee if I want to walk well again. I can
find it if I have to, but that will about wipe us out. Then how long will
I get to use it is the next question. As a type 2 diabetic, and 79yo, I am
statistically well past my use by date already. So we wait & see. Sigh...
Cheers, Gene
