Here’s one I recently put together. It works great. The panel was about $140 shipped and the motor another $120, both on ebay. I could have found a motor cheaper if I had wanted to wait or drive to buy a used one locally but with fuel costs going up I’m really getting into mail ordering everything. It’s a Baldor and in good shape so I reckon it was a good buy anyway.

The motor is 5 hp and the panel rated for 5 hp. In terms of usable 3 phase power I doubt it would be appropriate for a 5hp table saw or shaper, but for my double motor boring machine it’s fine.

Putting it together wasn’t hard at all. I already had a circuit with 10 gauge wires I was able to modify to supply the needed 30 amps at 220 volts, single phase.

After I was sure it was working I cut the idler motor shaft down to about a 1” nub.

No photo but I used to have a Roto-Phase that would run about 20 Hp simultaneously. I don’t remember the model number. It was around 20 years ago.
It was a great answer to the problem of moving from industrial to home shop without having to sell / re-power all my big tools.
It looked almost exactly like the one in your photos.

I put it on a board with rubber feet. Otherwise it creeps around
when it runs.

Loren, I think I am going to keep a look out for a 10 hp motor. Mainly because in the future I have considered adding machines up to 7.5 hp such as shapers and planers, maybe a 3 phase belt sander, etc… So I might put this all on the back burner for now until I come across the motor I need. I think I will call some local motor shops looking for an old 10 hp motor. I am not in any hurry right now. But I am looking forward to the addition of 3 phase to the shop.
