I noticed that you've got your pulleys backwards from my vintage craftsman lathe...meaning that on mine, the motor pulley has the smallest end closest to the motor, and the lathe pulley is the opposite with the largest end closest to the headstock. Is an advantage to having it the way your lathe is set up vs. the way mine is set up? Or is it just a matter of that's how the manufacturer put it together/personal preference?
I don't think there's an advantage to having the pulleys either direction. I suppose the argument could be made that the belt drive transmits the most torque (i.e. more belt tension) at the smallest motor/largest lathe combination, therefore it's best to have the large side of the pulley against the headstock to keep it closer to the bearings which could reduce vibration and extend lathe bearing life. One second note: my motor is not original. This lathe is a very old Delta. The original motor was massive and spun in the opposite direction so it faced the lathe rather than being tucked behind the headstock. This motor was taken from a furnace fan.
thanks, but focus focus focus, we dont CARE why you set up your shop and where/when you got your pulley. Engineering details please..These videos showing us how to drill a hole or tighten a bolt. We need the engineering please. Dont mean to complain, But most of this is tangential to what you did here. (Im working on improving alternator drive with V belt, by adding a back side pulley, it works! 150 amp output with no belt squeal)
Currently dealing with this same issue your video was so helpful- thanks.
Great video mate. Given me some ideas to cure my own belt tensioning problem. Cheers.👌
From where I can buy a tensioner like that?
I have the exact same lathe. I used a DC motor from a treadmill on mine. Works great for the variable speed.
I am amazed you have the same lathe. It seems so vintage!
Very informativ video, thank you, you gave me an idea for my own lathe and new pully system.

Good video! Thanks for the tips
a tip for you: you dont want to reach over the lathe to turn it off.
Yeah, I'm not happy with the switch placement either. It's on my list of things to fix.
