![]() There is one "uncouth" thing on the SAG 12 and SAG 14. Yet it is a most beautifully made piece of machinery, hardened and ground parts everywhere, when you take it apart it seems built at cost-no-object. (And the toolmaking trade school I attended had a SAG 12). For example, my SAG 12 manual says the lathe is aimed particularly at vocational schools. I don't think they were particularly expensive lathes, but I have no figures to back that up. Because of their unique double-height vee-ways, they can swing massive sizes in their natural gap, this doesn't make them a heavy duty lathe however.Īs for cost-no-object - I am not so sure about that. I would not describe Graziano lathes as heavy duty, they are not great lumps of cast iron, sort of medium duty I would guess. The carriage itself is cast iron, maybe steel on cast iron is an acceptable slideway combination, I am a little dubious. I just assumed it was cast iron (despite being rectangular and machined-all-over) because of its wearing properties. Steel would be much stronger than cast iron, and it needs strength because the compound slide assembly is clamped to external vee-ways/dovetails on the edges of the cross slide. ![]() I'm curious about that - on a cost-is-no-object lathe like the SAG, why would they not use cast iron for the saddle? Is the machine so massive they didn't think they needed the vibration damping of cast iron?I am not sure what material the cross slide is on a SAG 14, it could be steel, but I would need to check closer. ![]() John, I shot you an email earlier today: on Doc's thread on PracticalMachinist, a SAG 210 owner mentioned that the saddle is steel, which is unique, AFAIK. ![]()
