After some troubles (Documented here: https://www.hobby-machinist.com/threads/my-vfd-is-having-a-stroke-pm1440gt.100760/) and some stolen inspiration from @Jake P (here: https://www.hobby-machinist.com/threads/1440gt-upgrades-and-additions.96854/)

I've decided to try out a Marathon motor. Got it for a steal brand new on fleabay.
I'll probably start working on things this weekend when I can take some measurements and fab up the motor mount needed for this hulk.


PS - Don't judge my Mill work. The mill is still a fancy drill press to me. :) - But I started cobbling together some parts for a turnbuckle to keep belt tension.


More to come.

Looking great so far! You’re going to love that motor, they are smooth as silk.
 
Do you have to modify the machine for this swap, or are you just beefing up the tensioning?

Take a look at jakes thread in my first post. Minor mods needed to the belt cover, along with fabricating a new bracket for the motor.
 
A new bracket for the motor is a good idea for any motor on the 1440GT. That factory setup is a pain do any kind of adjustment.
 
Agreed. The factory setup is certainly compact, but it's like working on a german car. Impossible.
 
Got a little done today. Cranked out some spacers for the lathe side mount, and trimmed the steel plate to size (And boy, do I need a real metal bandsaw. Portaband is handy but not cut for this kind of thing!)

I've got a bunch of 1144 roundbar I was going to make the hinges out of, but the internet says it's not really a weldable steel. I'll get some bar tomorrow from the local metal place.
