Large vertical lathe

[Frank S]

With my obvious fondness for large machines, I found the ultimate vertical lathe. What I'd give to have been one of the ones millwrighting that thing onto its mounting

better get to work making those T-nuts...

I like how it can make three vehicles at once...

I think about the probably even larger machines needed to make that very large vertical lathe. I wonder what is the expected run out on that table

[mdhatter3]

Will that fit into my basement?

Appears to be dual-tabled. The smaller table would run higher RPM, to reach proper surface speeds.

A comparably large vertical lathe at Long Beach Shipyard, a Betts of 19'. 50hp, .32-12.8 RPM @ feed rates .004-1.5 inch per minute. Maximum table load was 165 tons at 0.75 RPM. Most VBL's of this size are D.C. generator drives to regulate 'infinitely variable' speeds. Most frequent use, boring of propeller hub tapers, max swing was 20'.

the one I posted sure beats the old 6ft dimeter twin post Bullard I used to have when I was making or reworking oilfield draw-works brake drums for National machine works. I could do that now though on my pencil sharpener without having to remove the brake drums from the winches. Had a young man stop by yesterday for me to do some maching for him. He said he would love to learn to run the pencil sharpener.

...and three different models.

...and three different models.

Just need tooling and fixtures.
Sort of.
