No setback here: there a Rockwell pin prick inside and outside.

I am with my 2nd Evan Williams and I do not have a clue what this post is about.

-a frequent, (and somewhat speculative) topic on this board is lug recess setback, carburizing, and hardness concerning Mauser receivers.

Other than that, richj has some of the neatest stuff you'll ever see around here

Especially when it comes to Argentines.

Did you know that thing on top of the stick is a "liberty cap*"?

Same here

I learn something new every day. I always thought of it as a used condom...

I just look at that from a machinists point of view and the tooling they had to work with back in the day.
Some very clean precise work for all manual machine operations. Even with jigs an fixturing. Very nice work

One of the things I always have respected most about the Mauser and 1903. The number of machining operations, jigs, fixtures, and SKILL that went into making them. All without a CNC.

Well it just goes to show you it's not the machine but the machinist that makes the beautiful parts

Considering that Mauser made 5000 to 6000 rifles a day during some contracts there was probably not much skill involved after a machine was set up. Each machine was probably left set up and the same old cut was made over and over and over until the cutter got dull.

I was on the USS North Carolina last year and they had an in-house machine shop (as I'm sure they all do) and it was awesome to think of those guys building parts off of rolled up blueprints and slide rules and what not.

I would have to respectfully disagree. If you are ever in Ohio you can stop by our facility. If I can sneak you in, I will show you our production lines. While those positions do not take the skill of one of the tool room machinists, it is still a difficult job having to account for a number of factors and variances .

Now, our products are arguably much more complex than the mauser and we produce in the neighborhood of 10,000 a day. However... we are 100 years more advanced That is not to say that we all could not learn a great deal from those folks.

Kcstott... have you ever run a completely pathetic worn out POS? I started making the argument it does not matter how good of machinist you are...

To jump in&out of the conversation- years ago I knew an old German (of course) man who got good production out of several worn-out machines in a shop I worked in. When he retired the management finally wised up and bought new machinery as no one else could coax a decent part out of the old ones. IOW the equipment was junk; the man's skill is what produced the parts.

A good machinist quickly learns to either adjust his shop practices to accomodate a worn-out machine or else to rebuild the machine to be within workable tolerances. I've done both approaches at various times, depending. It ain't THAT hard but you gotta be on your toes at least a little bit.....

A POS machine will not stymie a good machinist for long, and a brand-new top-of-the-line CNC setup won't make a klutz good enough to do a craftsman's work.

Boots Obermeyer told me that he has over 80 machines in his shop, with almost every one set up to do one specific job and hardly ever reset for anything else. He said he loves to buy & rebuild old machines, he called it an addiction to cast iron.(grin)

Ha... try telling that to management. You'll get the same response I do every day. (insert beating head against table smilie face here)

Can you make good parts on it? Sure, as long as you do not need to ream a hole and have an entire day to do a 2hr job!

I definitely have old iron disease... wish I had room for 80 machines!

For you machinists: How many separate setups would be needed on manual machines to reproduce the Mauser action? What would it cost today?
