PW changed, and the order submitted.

Thanks to everybody who replied.  Spooked me a bit, they used pix of a 
3/8" long screw.

And a 25-30 day delivery too...

That means I'd have to change my PW, I have an email saying I must that 
came in yesterday.  In the meantime I am watching my bank account 
frequently.

Because of that, I was looking at places like Graingers.

Not that I've made note of.  And I do get in there several times a year.

Thanks Raymond, but I think the non-ferrous, because of its lack of 
induced magnetism from a stray screw driver is in order, and I've since 
figured out what I can to tomorrow to get going again. I bought 3 screws, 
but only two are going in at this time, so I have a ready-made spare in 
the third ball screw assembly.

John understood the human creature well. But too many do not want to 
listen to the truth.

There is one, "Hobby Stop" in Bridgeport, and I intend to hit them as the 
first 2 choices if I make the trip.  It has occurred to me that while I 
have 3 of these ball screws, the third one is not going in, at least in 
this project, so I can borrow a screw from it & baggie the rest of that 
nut for later use.

Getting slow in my dotage I guess, I didn't think of that ready made spare 
until after I had posted.  That plus I made up my mind to lose some lard 
this spring, and saw 156.6 lbs on the scales this morning.  Reducing the 
load on my worn out, used up back, it was carrying 205 12 years ago when I 
retired. Way too wide for my height. 5'8" 60 years ago, 5'2.5" now. I 
figure something around 140-145 ought to look good in the hallway mirror.

But the "Hobby Stop" was on my list & will be at some point.  My selection 
of telescoping brass tubing is getting poor & needs replenished.  And it 
looks as if I should also pick up some solid brass rod of similar size in 
case I have to make one.

But replacing the Z screw in this POS with one of those 13"ers depends on 
if I have enough down travel from where the nut holder is welded to the 
post extension, the existing screw, also my design, is half a 3 foot 10 
tpi 1/2" acme.  I adjust the backlash there by re-timing two 10 tpi nook 
nuts screwed into each end of the ball bearing supported, rotating nut 
carrier, the screw doesn't turn, and now that I have roller (ball bearing) 
feet on the head casting, it will do 1 to 2 thou backlash pretty reliably 
with no stiction.  Hiding one of these ball nuts inside that contraption 
will be fun.  Not impossible, but fun, depending on one's definition of 
"fun" ;-).

Thanks for the quick reply with a useful suggestion Greg, its appreciated.

Cheers, Gene Heskett

Dunno if Home Despot would stock screws that small, or if in a nearby

Do you have a decent hobby shop near you, Gene? They usually stock a pretty 
good selection of tiny screws as well as other useful bits.

[Emc-users] Need a 2-56 screw about 1/8" long & hate to buy 100 to get one.

[Gene Heskett]

Greetings all;

While working on my mill, putting ball screws in this sows ear, I needed 
to reduce the size of the ball nut itself because of insufficient room 
under the X table for the 19.07mm diameter nut, and anything that could 
function as a nut holder.

The clearance was about 19.17mm.  Not enough to allow a wrapper on any 
strength at all around the nut so as to allow anchoring it to the top of 
the Y drive slider.

So I stripped the nut, and used a dremel diamond disk to reduce its width 
to about 15mm, which still gave about 1.5mm of steel around the ball 
tracks in the nut.

But when I was re-assembling the nut, I managed to drop one of the 2, 2-56 
x 1/8" screws that retain the nuts ball recycling tube hold down strap.  
This screw is about the same length, but about 2 times the diameter of the 
one in the bow hinge of most glasses frames.

Dropped in about an inch of leaf & twig litter from a Maple tree in the 
neighbors yard across the back fence on the deck flooring in front of my 
shop building.  Assuming it was steel and that one of my dial indicator 
magnetic bases would pick it up I spent about 20 minutes stirring in the 
litter, sort of sweeping it into small piles I could pick up and drop in 
the trash can, but never picked up the screw that I know of.  It finally 
dawned on me that while it was white, it could be plated brass.  Dragging 
out a screwdriver that was known to be magnetized, I confirmed the other 
screw was indeed non-ferrous.

Oops.  But it makes sense as one would not want a magnetized screw to 
impede the otherwise free rolling balls.

And apparently its gone forever.  So until I can find another, also brass, 
I am dead in the water because I cannot re-load the nut with balls until 
that screw hole, which is just big enough to let a 1/16" ball leak out, is 
plugged.

To buy it out on the net will cost me at least a $20 bill (100+ship), and 
with minimum order charges, possibly as much as $50.

So I am headed out in the morning to look for a semi-local place where I 
might get lucky and find a brass screw that size, and failing that, some 
brass stock suitable for making one, but I've no clue if my single tooth 
can make one of those.  56 tpi seems like it would push the G76 canned 
code about as far as it can be pushed, although it has made some very good 
32 tpi threads.

So, if I fail on this, I'll be back in a day or so, asking folks to go 
thru their "hell boxes" to see if one can be found.

Cheers, Gene Heskett
