Someone near me is selling a Cincinnati No. 3 vertical milling
machine.

http://igor.chudov.com/tmp/Cincinnat...ng-Machine.jpg

I am sort of famiiar with the look, as I saw similar milling machines
(probably Russian knockoffs) in Russia when I had my lathe operator
practice in high school. But that was a long time ago.

This is a large machine, say, 14,000 lbs or so. The motor is 20 HP or more.

My question is, is it totally insane to just keep it for general shop
use? I have ability to hook it up and use it.

Near here is a machine shop with somewbat larger tools. The owner/
operator says he likes to do jobs that no one else can do. That size
machine could handle Tom Gardner's ratchet wheel. I would hook it up
and keep it as long as you have room. You can always sell it later
if you run out of room.

It looks like an awesome machine, but I can't possibly think of what
you'd need a machine that big for that your other series 2 Bridgeport
couldn't do just fine.

I have a person who is our CDL Class A driver, weldor, repairman, etc
and he needs a manual milling machine, hence the question.

Well, it would keep your building from floating away... Probably use $5
in electricity every time you start the spindle... Snap 1" end mills
like toothpicks... I bet you could experiment with stir welding aluminum
with it...

It is a BEAST! If you have need for a larger mill, then it may be
quite useful. Do you have tooling for the spindle taper?
It doesn't make sense to keep if you don't have use for a machine
larger than your Series II Bridgeport (although it likely is more
rigid than the Bridgeport, just judging by the weight.) It has
no CNC, no readouts, and unless it has power feed on the knee,
**I** sure wouldn't want to crank that knee up!

One should not be learning the art of machining on a 20 Hp

Ive run them. They are a hell of a machine if you are doing a
lot...lot of metal removal from Large castings, forgings and similar
work.

Do you need a BIG mill?

Or will a Bridgeport/Gorton/Lagun do your jobs?

Its gonna cost a little money to move it, set it, wire it up and then
its gonna cost to simply turn it on.

Its more than likely 50 Taper, which can be very very cheaply had. And

If it is 20 HP, it should be about 60 amps 230, not a big deal for

I just wanted to point out that if he is learning machining, such
a powerful machine might not be the place to start. I've had a
few accidents and oopses over the years, and because I have a
fairly modest, low-powered machine, none of them were too
serious. I've had workpieces pulled out of the vise on a
number of occasions and had to dodge the flying parts. Once
it swiveled the head of my series-I Bridgeport about 45 degrees
before the motor stalled. With 20 X the HP, these could have
been bloody accidents instead of just minor repairs.

Jon

I saw the subject line and I thought "Why not?"

Reminds me of a time, when a group of us were considering going in
on a PDP-8 computer - surplus from the University. Stick it in
Threadgill's basement, and we could have our own dial up computer.
Wicked cool! The caper was that at the time, home computers were not
all that prevalent, and at the start of classes, there would be the
usual question of "Can I use my computer at home, instead of the
University's?" "What do you have?" And then the look on faces when
you say "A PDP-8. It's the one all my friends have."

Unfortunately, it didn't work out at all.

Never underestimate the power of a meager 1HP machine. Heck, I once had

Near here is a machine shop with somewbat larger tools. The owner/

Well, if in good shape, it should be very nice. Of course, all
the usual things can be wrong, like worn ways, badly worn
leadscrews, etc. When I put a readout (not digital, but optical)
on my old Bridgeport, I was amazed at the differential wear on the
X leadscrew. I didn't think it was possible for it to be worn
so much in the center without the entire thread going away.
I had very close to .050" error in the middle, then it would start
to go down after passing the center. Well, that explained why
I couldn't make any larger things where the bolt holes lined up!

A DRO might be the easiest way to make accurate parts with it.

Indeed. And a couple times a year..move the damned vise from one end
to another and spots in between.

A LOT of mills were never run that way..and have horrendous wear in
one spot.

Same with most lathes. I dont care if its a 54" lathe..there is going
to be wear within 8" of the chuck/spindle nose.

Same with CNC machines of all sorts.

4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie

Well, if in good shape, it should be very nice. Of course, all
the usual things can be wrong, like worn ways, badly worn
leadscrews, etc. When I put a readout (not digital, but optical)
on my old Bridgeport, I was amazed at the differential wear on the
X leadscrew. I didn't think it was possible for it to be worn
so much in the center without the entire thread going away.
I had very close to .050" error in the middle, then it would start
to go down after passing the center. Well, that explained why
I couldn't make any larger things where the bolt holes lined up!

A DRO might be the easiest way to make accurate parts with it.

Indeed. And a couple times a year..move the damned vise from one end
to another and spots in between.

A LOT of mills were never run that way..and have horrendous wear in
one spot.

Same with most lathes. I dont care if its a 54" lathe..there is going
to be wear within 8" of the chuck/spindle nose.

Same with CNC machines of all sorts.


I thought that with proper lubricatio n, everything rides on a film of
oil?

"proper lubrication"

If there was such a thing...machine repair guys would be out of
business.

The methodology of the left has always been:

1. Lie
2. Repeat the lie as many times as possible
3. Have as many people repeat the lie as often as possible
4. Eventually, the uninformed believe the lie
5. The lie will then be made into some form oflaw
6. Then everyone must conform to the lie
