"Seems" is the operative word there. Given a choice between making one by hand and programming a 5-axis trunion milling machine with robotic loader, and I'd pick making it manually. Holy cow, that is some impressive work they did in that video (and a staggering amount of programming and setup).

Hardly related to "old machine tools" but, cool nonetheless.

I started out looking for old machine tools and that where I wound up. Hopefully some of the machinists here will have some stories about their own "Turner's Cubes". I used the wrong name for them in my prior post.

I could post pages and pages. Here's just what I saw when I glanced through my pictures folder:



















We have cabinets, chests, and drawers full of other tools.

I like the machines we have that have the "War Effort" labels on them. they have feeling. something. that makes you think "who ran this? what did they make? who where they?" and ya know? they might be fickle, cantankerous, and dirty. but get the touch. the feel of what they can do. thats a good feeling. master something that someone else used 60, 70,80 years ago?
and yes the last place I worked had a 1914 Lucas horizontal mill. "War effort" but another older war...

and it's funny. i'm the kid in the shop. these guys all have 20-30 years on me in the trade. and they laugh when I take pics. to me it still means something more than a check. pride in workmanship etc...they've lost that. so sad. and you can tell who's lost it. you can tell who turned what.
maybe thats why I connect with the hands that used these old big bastards when the were Brand spankin new. they had a goal, a mission and were proud of what they did. it was more than a check.
Great words. Great thread.

awesome that you still use all that like it was meant to be.

my first attempt at video a while back. the Springfield is mothballed now.

if i remember right it was a 5000lb old sand cast iron rod from a press. there were two of them and the they had a six in core down the middle with chunks floating around and huge sand pits full of glass. notice how out of balance it was.



if this works

This shop's been in constant operation.

The chuck on that large lathe was made in the same factory in Germany as K98's. Different twist on the war effort, I suppose.

In the last shop I worked in, we sharpened small perp dies on a Property of the War Board surface grinder. It came off a Navy ship.
I didn't like running it, though it was smooth enough. The head would drop every now and again, about .03", and of course, blow up the wheel, fling workpieces, generally make a big clatter. And keep right on slapping back and forth

When I was at Boeing Wichita in the early '80's, I saw what must be the world's largest roll
At least this side of anything the Rooskies might have had. The rollers were 60' long, and all three were at least 36" diameter. Used for contouring B29 wing skins I was told.

70's Lucas. just like every other lucas.
boring H-13 pillow blocks. yeay.

I admire your shop and the equipment you run. At the age of 59 I have seen the transition from machinists to machine operators to a depressing decline in American manufacturing. One stronghold of machining skill is the repair machine shop that repairs or duplicates parts that are either out of production or available only with long lead times, from very distant vendors, or both. I take it that you are in that kind of environment.

A real machinist is to be admired and that person will never starve and will always bring value to his company and this country.

On a different note — something to consider. Some of us have had conversations over the years that go something like this. What if all of it disappeared and all we had was our knowledge as we were placed upon the land. No tools, no nothing. Starting from the environment; a rock and a stick. I will give you the knowledge. How would you start and what steps would be necessary to get back to what is now possible? How long would it take?

Also, is there one machine tool that could replicate itself? How do you make bigger machine tools? I have looked at very large machine tools and wondered, how was this made? How do you machine ways on a lathe longer than any presently existing machine is capable of doing?

How many still know how to hand scrape ways?

These are things for you to ponder.

I have a set of several, leather bound books that belonged to my grandfather. They are dated 1904, I believe, and cover industrial and manufacturing processes including machining. It is of interest to note that virtually all of the processes available today were in existence at that time. The differences being the tooling being used, and certain elements of machine contruction. Today we have ball screws, ball bushings, features that work with CNC and enhance repeatability and accuracy. The processes were there. Some of the machine tools were quite large.

Elsewhere in this thread is comment about a big set of forming rolls used by an aircraft manufacturer. Big stuff is neat. I would love to see plate formed in a ship yard.

I don't know you, but admire your skill, your spirit, and your interests.

America needs to manufacture to be great again.

Good job.
