How slow does it go and can it run there for long periods without heating up?

It will run at less than 100 rpm's indefinitely with no noticeable heat. There is also very little heat at higher speeds unlike that AC motor which got so hot you could barely hold onto it to change the belt to another pulley after a while.

I made a really small pulley for the motor. It will turn the lathe at 50rpm. I let it turn for hours while the cue cote cures. No heat what so ever!

I have my belt on the second from the smallest pulley so it's capable of going quite a bit slower if I move the belt.
I am building a very simple wooden bed lathe just for finishing and powering it with a small DC motor direct drive with variable voltage. No need this way to worry about spilling on the bed of my real lathe or tying it up. And whatever finish I use can just spill and spatter to it's heart's delight. A drill chuck on the drive end and a spring loaded live center on the other. I have ran the motor I'm using for many hours at slow speed and it also creates very little heat.

DC 1/2 motor
The 2nd motor , I have one and another one on its way its very quiet, and runs perfectly..
As said above the TSP motor mount on a large bore spindle works great.....

I never really had hands on one of those...... did not know that..............
BTW.... I love my lathe......... I do everything on it....

I do that also ..... I run it over night sometimes.... the motor is cold in the morning....

I let mine run over night often. With the old A/C motor the lathe turned to fast for the finish I use.

That squeaking was so well timed for the video . No wonder you put in the disclaimer.
When I do my next project will have to price up one of those shipped here. There was a sewing mc place selling them out here, but wanted more money than the cost of VFD and 3 phase motor .
Maybe the ebay people can ship fairly cost effective now days somehow.
Thanks for letting every one know.

My sewing machine motor swap
Some while ago I posted about installing one of these sewing machine motors on my Porper B lathe. All I really use this machine for is gun drilling and finish, and this motor works well for both.
For effortless boring a low drive ratio is best. I ended up with about 3.5:1 with a motor pulley I made myself. The motor hardly gets warm.
The same is true for turning slowly when drying epoxy. It will run dead cold all night at very slow speed.
I like it.
