Sheldon CM 56 Turret Lathe

Turret lathes and cigarettes

Before I got my journeyman papers I often had to run a turret lathe. You always got the coolant on your hands and it made it hard to smoke.
 
What we have here is a different definition of what a "high precision Lathe" is.

We have bought about 1.2 million dollars worth of " high precision" Lathes in the past 4 to 5 years as part of our upgrading program. None have Turrets. They are all full class Engine Lathes.

Now, if you are talking about CNC Chucking Machines and Turning Centers, of course they have what amounts to Turrets in multiple station tool assemblies.

As for the little Turret Lathe that Nez asked about, I can say this for a fact. I know a lot of Machinist who chamber and fit barrels. I know a lot of Gunsmiths who chamber and fit barrels. And I know a lot of Hobbyist/Shooters who chamber and fit barrels. I do not know one single person who uses a little Turret Lathe like the one in the OP to chamber and fit barrels.
 
Back to your regular programming.....

Speaking of engineers, we have a first. A slide rule nerd (making a big assumption since Tillerson and I were in different engineering schools about the same time, and I was proud to carry my K&E) is now the Secretary of State. That is something I thought I will never see, not a lawyer in that position....

It was rather humorous watching those career Polititians question Secretary of State Tillerson and his qualifications.

As for the slide rule, when I took physics my senior year in high school, we had to buy a simple slide with the A,B,C, and D scales. It came with a nice "scabbard" that hung from your belt.

The Math Club had district contest where all of the "Nerds", (to me, that is not a derogatory term), would gather and see how fast they could solve various functions with their slide rules. To say I was less than adequate in that arena would be an understatement.:eek:


I have no idea what happenned to my Rule after I graduated.

What a blast from the past.

In the univeristy, Physics Dept sponsored a yearly slide rule contest, the Chinese kicked our butts......

Gents,

Save your breath in trying to have a rational conversation with TRA. Over on the "New 4473 in the Mary Jane states" thread, he was trying to tell me what I can arrest people for. Engineer, machinist, business owner, project coordinator and, apparently, a brilliant legal mind to boot!



The SR-71 was built by slide rule. Kelly Johnson...there was an engineer. If you ever find his autobiography "Kelly", grab it. It's a good read.

I still have my big one w/scabbard (copyright 1965). I also had a shirt pocket size, I haven't seen that one in many years. Last year my Son-in-law (a Scientist) was visiting & we were poking around & ran across the slide rule. I tried to show him how it worked (he'd never seen one) & I realized it's been a "long time" !! :)

Justin, It appears some think that your statement is true. Chuckle chuckle

About 10 yrs ago, or so, I stumbled upon a 'dedicated chambering machine' manufactured by who else , but Pratt & Whitney. It was a specialized turret lathe complete with provisions for a 'muzzle flush' system. It was a WW2 vintage machine, and to turn the handles and cycle the turret, it was a trip back in time. Machine tools just aren't made like that anymore. It was on the same frame as P&Ws' single spindle rifling machine was built on. I wish I'd have taken some pics. That machine probably thread & chambered thousands of Springfield and Garand barrels during the War.

Clarance "Kelly" Johnson. Now that was THE,engineer.i loved to read about him and the Lockeed
Skunk Works...SR-71, P38, F80, F104 (400+ to 50,000 feet-vertical Mach 3.5+ flat out), Electra, all innovations for tomorrow.

Want some great reading, read Ben Rich's book about Kelly. Ben Rich,was the,engineer who took Kelly's place when he retired. I met Kelly when he was on a motivational speaking tour in Vegas.

No nonsense, just do it.

Gents,

Ben Rich's book is called "Skunk Works", and Jerry is right...great read.

So, once you come in and, as you said, "muck up the thread", you want to forget about what was said.

You make rash statements about various methods and capabilities with the assumption that you are correct. For instance, "drilling a hole", "Boring with a totally unstable boring bar set-up", Reaming with a worn out out of alignment tailstock" etc, etc, etc.......

Are you assuming that anybody that does not adhere to your procedures and your ideas are idiots, and are simply "painting by the numbers" with the hope that every thing will come out OK?

I have no idea who you are. You might be a master craftsman who is at the pinnacle of the Machining Industry, or, TRA could just as well be some 30 year old with a computer living in his parents basement, trolling the Internet with a info garnered off of Wiki.

Most of us on this Forum use our real names. Many of us know each other personally. When we say something, everybody knows exactly who they are listening too, and can make assumptions based on that person's reputation through accomplishment in Real Life, as opposed to someone's reputation in "Cyber World".

Right now, all we know about you is your reputation in Cyber World. So I would ask.....Do you shoot in a Competitive Arena, whether it be Benchrest, High Power, F-Class, Prcision Rifle, or any other of the many Competitions that require not only certain skills as a shooter, but certain skills as one who knows how to assemble a winning Combination. Do you work as an Engineer, Machinist, Business Owner, Project Coorrdinator, etc.

When myself, or any other of the named contributors come on this Web Site and discuss things, We are in a sense putting our reputations as a craftsman, shooters, and people of accomplishment on the line. If I say something assinine, I have to be willing to recognize the fact that my peers will know that. TRA does not share that same degree of culpability.

So, I will ask. Are you willing to use your real name on this Web Site, so you are putting your real life reputation on the line, or are you just going to be TRA, who suffers no ramifications in the wake of his trolling?

Found it, I must have been at the range when Jackie posted the above.

Gawd, I wish I had said that.

Thanks Bro. We owe you,

I think that's why gearheads, greasemonkeys and chipsoles have those smudges around they eyes..... when I hold a smoke in my pinky I end up wiping my cheek with the other fingers....
 
I could be wrong looking at pictures but that looks to be a chucker instead of a turret lathe, turret looks to be on cross slide and there is no turret where tailstock would normally be ?????
 
NezRongero said:
OK, I give up, educate this kid. What is the fundamental difference in the intended use between a chucker and a turret..
Click to expand...

Normally, on a lathe a tool turret has 2 axis of motion, X and Z. A tailstock turret has only Z axis motion.

Unless the turret rotation were a resolute programmed axis in which this rotary motion about the Y axis would be the B axis.

A chucker has no tailstock turret.
