Hi everyone, I've been working on getting a 1941 hardinge TM up and running. It's all original, including the original drawbar. My question is: how was the drawbar designed to be tightened? It looks like a handwheel, but I don't think I can get it tight enough by hand. I can get a large spanner...
In the first picture, that is either the wrong TS for the DH, or a model i never saw.
It looks like the 4" TS for an indexer. The DH is 3-5/8" and you can see through the DH TS casting.
Also curious about the thumbscrews? on each side at the base of the arm that carries the index plunger?
I believe that "blocky" style design dividing head is the "first variant" style. I have no idea where the photo/illustration came from. Agree on the tailstock and those thumbscrews, have never seen those before. Perhaps its a pre-production illustration? Perhaps @L Vanice knows more?
I've got one of the "blocky" DH's along with a couple "Egg" cases.
But have only seen the "see through" TS's for them. Some of the early ones (TS's) seem to have had black crackle paint, but all mine (7 at one point) were/are smooth grey/green like most of Hardinge's stock products.
