Unfortunately most of the high schools around here (Illinois) have closed their shops and most community colleges don't offer any machining classes either. Unless you can find an old machinist to take you under
his wing, YouTube is about your only option.
Where my son teaches there are two campuses,? East and West Leyden high schools.
He's primarily at East but is chairman of the department at both.
This includes machine shop, wood shop, auto shop and construction!
East has had a machine shop forever,? they just opened a brand new one at West a couple years ago. Very nice!
Manual and CNC. Turning, milling, a little surface grinding and while not really an official part of the curriculum, welding.?
He's got a pretty solid background, used to work with me part time while in HS and full time prior to the air force.?
Now he's an "aircraft metal technician" in the air national guard.?
Classes are pretty full and he comes up with a lot of cool projects to keep up the interest!?
He works with a lot of local shops that will hire a kid tomorrow with his recommendation.?
It's all good.?

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
