...and also, Ken, how much would you charge for a set of custom jaws for stummel work?

Some of those big ones run on deisel engines and some are HEAVY DUTY electric with serious transmissions.
THe one my dad ran before he retired was not quite that big. I think it had a a 72" swing and 28 feet between centers. It ran on a deisel engine. He made a lot of large things like 2 foot diameter hoist pulley shafts that they used to lift heavy equipment up and down the mine shafts with.
THat big lathe still only ran about .0005 out on the spindle.
They had a heavy duty hoist rigged up above it that they used to lift stock into the chuck with.
Dad often took cuts 1" wide and 3/8 deep in one pass with it. I can only imagine what the one in the picture would do. At that point it is very important to be able to grind chip brakers on your lathe cutters. A ribbon of steel 3/8 thick and 1" wide and turning purple as it peels off the bar would be a little hard to handle.

Now that sounds scary.Ray Cover wrote: Dad often took cuts 1" wide and 3/8 deep in one pass with it. I can only imagine what the one in the picture would do.

And fun.
More fun than scary though.....

I see you also had fun checking out that practicalmachinist forum. There's a wealth of useful machining info there. My brain is still roiling trying to remember much of it for future reference.
One of the forum posts convinced me it's worth the cost to get these belts for my shop machines: http://www.grizzly.com/products/h9816
I'm expecting them in by the end of the week.
