spindle,headstock,gear box.. norton??? (i know ways need way oil)
 
Lathes are not automotive engines or transmissions. The only thing that turns at anything approaching those RPMs is the spindle, which is the one thing you usually cannot lube. Just about anything is better than nothing. Use a hypoid gear oil in gearboxes and a way oil (Just buy a gallon of Mobile Vactra and it will last you for years) for the ways and leadscrews. I'm sure there is a "best" product, and you want something that won't attack seals, but don't worry to much about it!
 
For many of the Grizzly lathes they recommend Mobile DTE Light 32 weight for the headstock/spindle/and various oil can port, Mobile Vactra 2 68 weight for the carriage, ways, quick change gears, screws. Why don't you have a look at a Grizzly manual for one of their larger lathes, they are all available on their web site.
 
Cool has it right. On most any lathe you can go DTE 32 for headstock, either that or medium (68) for gear box and Medium way oil for the carriage and or way oiler. On some lathes the carriage and way oil are in same reservoir as the way oil is spread by automatic oiler living in carriage sump. If Mobil is not available, you can use turbine oil, bout the same thing. So basically a light oil (old style 10w) for headstock, 20 w for gear boxes and 20-40 w for the way oil depending on situation, loads, temps etc.

Its not japanese, its american, made by Homestead Machine Tool in Norwalk Connecticut.

I guess doubleeboy comes close to it, the lathe beeing from the 60's.
 
My Cincinnati Tray-Top lathe, a geared head lathe from 1954, uses either ISO 46 or ISO 68 viscosity hydraulic fluid for headstock, carriage and all other machine lubrication, except exposed gearing on the end of the headstock, as specified by the manual.

I suspect the DTE 32 may be a little light but that the DTE medium (ISO68) would probably be good.

John, the lathe seems very similar in size and spec to the Mori Seki or Okuma LS 450. I would look up the oils the LS 450 uses as it would appear to me to be a pretty comparable machines with similar speed range, gear box and headstock design.

I know this is and old thread but I have that same lathe. On my first job as a REAL machinist in 1971. I bored out fiberglass pipe flanges on it. Talk about an itchey job. I aquired it some years later and use it in my home machine shop. Ways had been reworked after the abuse of the fiberglass. I have the books and schmatics that came with it. If interested I will see if I can dig them out.
