Antique lathe still in use

Pretty sure he means flipping that flat drive belt from one spool to another. It's a royal pain in the ass.

I have only owned belt drive lathes and don't find an issue swapping the belt around it's quick and easy. Though I imagine back in the day when it was on an overhead line shaft it may have been a pain in the but.

You flat belt lathe must have a tensioner. Mine has a bunch of bolts. Yuk.....
 
I have Hendey tie bar spindle lathe from 1918. Still in working condition. not as precise as I wanted it to be, but fits almost all my needs. I will have to rebuild split nut as original (?) made out of babbit is completely worn out.

Yes it does. Seems odd that you would have a bunch of bolt to change something that would need to be changed constantly thought a days use.

It was original built to be in a factory with a big long overhead belt drive system powered by horses or a water mill or..... Each machine had their own drop. The previous owner installed an electric motor that drives the secondary pulley that would normally be driven by the overhead drive. When he installed the motor, it was bolted to a frame assembly. When the flat belt is moved, it would normally stay the same size so all that was needed was a minor tensioner. That doesn't work anymore with the motor drive system.

What do you mean by belt flipping, I am not familiar with that term. I can post some videos once its up and running. Can't say when that will be but hopefully in the next couple of months. I intend to make a graduated dial for the cross feed one day.

I am running a 1929 13" South Bend. It has a few battle scars, but don't we all? This was a water pump housing that someone let freeze, so I got it for free, tig'd the cracks back up and refaced the mating edge and o-ring groove. A quick carb clean and now I have a decent little fire pump to go with the 1000 gallons of water buried beside the house....

I am officially feeling spoiled then...
When I reassembled the Crawford, it was one adjuster for the motor to gear box, and one for gearbox to cone head...
Changing speeds takes less than 30 seconds with that big gear box.
I suppose if a fella was so inclined...enginerding some kind of back and forth arrangement to move the motor and gearbox over each of the 4 cone levels...but then it'd probably wreak havoc somewhere else...maybe that's why it's not already set up that way
It's been said numerous times...these older lathes didn't see high end speeds when built
