'turntable' that looks like a huge faceplate with T-slots in it. It has a
big gantry over it that mounts a tool holder. These things run to 15,
20 or more feet in diameter. Many of them are owned by the US
Navy, and kept in warehouses somewhere for occasional use to
repair battleship components. The Navy leases them out when somebody
needs one. MSU (Michigan State University) leased two of them
when building some cyclotrons a few years ago.
- Just in case you find one of these big ones, I have a Starrett inside
micrometer that'll measure to 36' (feet). It takes at least 2 people to
1510 West Glenlake Avenue

a vertical lathe of the proportions described in this thread of

repairs the rolls for paper mills has an equally long bed length.

at 60 ton.Most of the large pcs. are for hydrolic presses and turbine

- During my senior year in college (Texas A&M) I worked for a large aluminum door
& window company there (Alenco). Designed extrusion dies and various workplace
special tools. The small extrusion press had a 6ft dia ram and operated at 3000+
psi! Take a 6in. diameter billet of aluminum up to near melting temp and then
squeeze it at that pressure (432,000 psi!) and it flows like toothpaste!
Somebody had to bore that cylinder, and turn and finish that ram on some big-ass
machinery! Later, after I was gone, they got a BIG press. 9ft bore for 9 inch
Manly machinery, to be sure!
