This is from maybe 1976, I'm older now with less hair.
Won't fit an Atlas though!

Nice pic.? What was that shaft for?
Were you measuring the OD or what?

That was kind of a "medium" size boring bar. Don't remember the dimensions but probably 8" diameter, maybe 6 or 8 feet long with a #50 taper. Can you see a series of slots? They're for the cutting tools themselves, indexable carbide inserted, made them too. We made 3 or 4 different sizes, those would have been 1" x 4", some adjustable and some fixed. The large hinged part is a support for the cutter, clamps on the bar. That one might have been for a 30" diameter hole! Biggest one I ever made was 10" diameter x something over 200" long. Boring crankshaft journals for Electromotive. Feed the bar thru, get everything aligned then a guy would get inside to put the tools in the slots climb out and bore. Safety first! I guess. Glad I don't work on big stuff anymore.

That reminds me of the largest lathe I was ever allowed to push the START button on.? It was or had been a steam locomotive driver lathe.? I don’t recall for certain what the swing was.? But greater than 48”.? Alamo Ironworks in San Antonio had it.? My Father-In-Law ran their fleet maintenance department so I had seen it.? So during the run-up to building the Alyeska Pipeline, we had them machine some test defects into 48” OD X60 line pipe.? For some reason, I want to say that it was a 60x240.? I could just about stand up inside of the steady rest ? ?

Now that sounds like a good size lathe!
Now I prefer smaller work.?
I do pretty often start with a 75lb piece and when I'm done it's reduced to maybe 12lbs!? I'm happy to have a trainee at work? to empty the chip pan though!

That looks cool. Some of the old big stuff wouldn't be so easy to reproduce today. I've been to the Illinois railway museum,? I'm in the neighborhood. They have some very cool things that make you wonder how they did it at?the time! Dave Matticks?

Thanks for the info Dave.? That looked like an interesting job.? I worked in a machine shop during before and during my college years, I actually miss working with my hands a lot.? As a airframe stress analyst, it's pretty much a computer jockey job with occassional trips to the floor to look at structure built on the line or test.?
Thanks for the pic and discussion.? Interesting stuff.?
