FWIW Completely removing deep pits is not necessary. Penetrol treatment after polishing top surface will help prevent the rust in the pits from thriving. Then JPW(or what ever is then still available) can take over to prevent future rusting.

Good to know, thanks JPG!

You could try to get a set of the original Retractable Casters or use a different option. Mike used different casters he found and can be seen on his thread at the link below. Scroll down to his July 19th post which is on that second page the link takes you to.

After looking through all the options, i think i am going to design my own caster lift system to work with my 4x6 legs. I have a good design in my head, we will see how it works in the real world.

I still need to add casters and tighten the one Allen screw inside the main shaft. But my rebuild is looking and working great.

I've started fiddling around and getting familiar with the set of Wards gauges that came with my SS.

I turned a piece of green maple that came from a tree in my yard, i was very happy with how the ring separated but then i got greedy with a gouge and snapped the spindle as i was finishing the piece up.

But then i cut a blank from some air dried cherry i have and something magical came out for my eight year old.

More minor upgrades today

Quick release handles for the tool rest make adjustments much easier.

And finally an rpm display that i will install at the back of the motor.

I am.still looking for an autotransformer to fine tune the speed as needed.

Hi Joel,
Looks like things are coming along nicely. Can you tell me where you got the RPM display and how exactly it works/hooks up?

Joel, an autotransformer won’t change the speed of an AC induction motor, but it may well apply a voltage that will “release the magic smoke”. Which voltage could be either higher or lower than the rated voltage. Induction-motor speed is primarily a function of the AC line frequency, not the voltage.

If you want a variable-speed motor, I’d recommend replacing the single-phase motor with a 3-phase motor, and powering it from a VFD. 3-phase Frame 56 motors are readily available, and are mechanically direct replacements for the original motors. Assuming good-quality components, this is an almost bulletproof solution that is favored in industrial applications. AutomationDirect.com usually has good deals on both motors and VFD’s, as well as decent documentation.

The other option is to retrofit a DC motor. A lot of hobbiests have repurposed treadmill motors and drives successfully, but those are a lot more work to adapt to the machine. The other downside is that treadmill motors have mechanical commutators, and sooner or later the brushes, and eventually even the commutator ring, will wear out.

Hi Darren, and thanks.

I got the rpm sensor from Amazon. This one is barebones and a little tricky to hook up, but basically there is a small magnet i am going to glue to the gear on the back of the SS headstock. Then drill a hole in the headstock to mount the sensor right where that magnet will spin past it.

Then the display will need some kind of little mounting box where i can see it, and everytime the magnet passes the sensor it will display how many times per minute it is going by on the gear (rpm)

It will also need a small power adapter.

Hi Dennis, i did not want to hear this as I have already ordered an autotransformer 🤦‍♂️

Thank you for sparing me the smoke test though, i am.looking at VFDs now and will explore a 3 phase motor in the future.

I do appreciate the info.
