Where do you find these great old pics?

Good grief, look at the size of the counter weights they're running on the face plate! I wonder what they were turning.

I love that all-gear-drive tailstock!

But any idea what that handwheel/bevelgear is for, on the side of the apron where a threading dial would usually go?

Looks as if it turns the bottom shaft thru a bevel.
Could it be the clutch ?

this was posted on the other forum:

"from the looks of it, the lathe has a D.C. Drive motor- not uncommon in the older shops. The older DC Motors used to use a kind of drum controller- sometimes referred to as a "Trolley Car" controller. This was to give a soft start and vary the speed. The handwheel to the RH of the carriage may well be for working the drum control switch to start/stop and vary the speed of the spindle.

It's used to advance the tailstock.

Look at how small the crossfeed dial appears. Is it possible they didn't even have one? Nice picture.

From the counterweights they had to be turning some kind of ecentric. Most likely a crankshaft of some sort. And that center looks like something Wonder Woman could use http://bbs.homeshopmachinist.net//wink.gif
