it sure is good to know that there are still "machine shop"
class's being taught today

??? ??? I went to hi school with both sieves,? Wozniak & jobs& several
years back they totally demo's all of the shop classes , they have a
computer science class & I hear a new maker space . the auto shop,wood shop,

??? ??? electronics class metal shop & mech drawing were all shi*canned
, talk about progress, surprised they don't' have any computer game
classes to help the students advance at game playin!!!!!!!!!

??? ??? tks for the center lesson if i get done with all the snow we
got I'll head out to the shop tomorrow & give mine a try . I have a old
Craftsman with terrible bearings

Hi Bill,

Here we go.

It's not real obvious how to take these guys apart as you may have
noticed!


I drilled and tapped two 10-32 holes in the front cover plate and used
a slide hammer to pull it out, not necessary as that didn't really
help in the end and I had to make a new replacement!


Anyway, the od of the point on mine is around .740. Put a 3/4" shaft
collar on it leaving a gap between that and the body and use 2
screwdrivers/ pry bars, whatever to extract the tip.

The shank is separate, use maybe a 1/2" diameter pin to push that out.
I used my 10 ton Dake screw press, it's on a taper so when it pops,
it's out. Put a box of rags or something under it so it doesn't get
damaged.

Then flip it over and use something around 5/8" diameter to press out
the bearing along with the front cover. Easy!


It uses a double row angular contact bearing, 3202 I believe. I was
able to remove the cages intact for a good cleaning.

Old hardened grease was the problem. Looks almost new and runs like new.

Polish everything up and put it back together. I first used NLGI #2,
had to do it again, too much drag so I switched to a Lithium #1. Shell
Gadus S3 V220C1 to be exact, couple dollars at McMaster. I love that
place and they're about 2 miles from my house! Don't use white lithium
and don't over pack.


My youngest son was USAF, now he's Air National Guard and a high
school "industrial technology" teacher, AKA machine shop.


Hope this helps.


Dave

Thank you Dave & Guenther.
Dave thanks for the pics.?
For internal threading is this typically what you would use and run the lathe in FWD?
I guess this is the most intuitive way.? The only thing different from the external thread is the compound? swinging to opposite 30deg.? The lathe rotation and feed direction would be the same.

Initially when thinking about this I was reluctant to set the compound up this way because it seems odd from normal turning process I'm more used to.
But now it seems intuitive and the simplest.

To answer you're questions:
-I plan on making an external thread first and if I can use it as a test piece for my internal thread.
-I do not have thread wires
-I do have micrometers and telescoping gages for bore checking
-I will cut a relief/undercut at the base of the thread inside the bore.?
-I have a mighty mag for now with a dial indicator that I will use to monitor the depth

Thanks again for the pics and advice.

Considering the chuck is threaded on, I'm
rethinking this.Yes. As the chuck is rotating,
the cutting forces run in a
circle
(relative to the chuck) and will almost certainly
unscrew it. I know, as it happened to me, even
though I was
taking a light cut for that
reason.

If you really snug
the chuck down, and take light cuts,
MAYBE
not. But, it will be a real mess if it happens. And,
if it happens, it will be near the end of the
threading
passes, with the cutter DEEP in
the thread.

Anyway, there
is NO REASON to thread this in reverse - just
run it in the forward direction.

No Jody To the left. I would not disengage the half not if the your 1/2 nut has a lot of wear. Back up under power. I hope you have a reverse on the lathe

Ok, I like
to hear that.Thanks for putting my mind at
ease.Would your method of internal threading on
the Atlas be to run it in reverse and have the feed go from
left to right, starting inside bore.and coming
out?
Thanks for the info.-Jody

In 54 years I had never had a threaded on chuck come loose.
Don't worry if you put the chuck on properly meaning
when you get to the last 1/4 turn you give it a hard spin so
you can hear a click the chuck is on it will not come loose

Andrei,I'm actually subscribed to his channel. He
is good and goes a bit fast for me sometimes.
This is his external thread video but he also has
an internal thread video.
If I remember correctly, he starts the cutter in
the bore, runs in reverse and the feed comes out of the

from left to right.
I'm a little nervous doing it this way

?

So I'm going to be doing some internal threading
here in the next week or so hopefully.?




initially I was thinking of running in reverse and start
the
cutting from down inside the bore and come out.?
Considering the chuck is threaded on, I'm rethinking
this.?


Although on a 1 1/2" bore, will the cutting forces
really be high enough with a 3/4" moment arm (from the
spindle axis) to unwind the chuck?? Probably not.?


I'd be curious if anybody has done this in reverse.?
Now if it was on a 4" ID, it would be a definite no
for
me to do it this way because the cutting forces would be
acting 2" away from the spindle axis and have a larger
moment arm to create higher torque to
unwind the chuck.



Anyway, being this is my 1st time doing threading, I
don't want to risk it so I will be staying in forward.



Question for running in forward direction:

What compound setup do you guys like to use??

????? -29-30 deg compound with compound axis pointing
away from head stock (backwards to how you would have it
for
turning)? I saw on Youtube "Tom's Techniques"
channel do this.

????? - Or set compound on 29 - 30 deg conventional
direction and flip cutter upside down and cut the back
side
feeding compound in with each pass.?




Thanks for any pointers and help,

Jody
