The axles with flange wheels look like they are live steam RR car wheel sets for 4 3/4" sized railroad trucks, which is around 1" to the foot scale. The 4 3/4" would be the gauge between the rails. One set appears to have the journal bearing turned on the end of the axle, the other three do...

Possibly this guy, his name is cuppajoe on youtube. Numerous videos about the upgrades he did to his "wrong fu" as he calls it. His channel; https://www.youtube.com/channel/UCIFgfhevO7S66kX1s8rd0qA

Did that; 32 x sqrt16.2 = 128.7975 but at what amps? Because remember my motor is rated 8.6v at 2 amps. So would that mean 0.1335 amps at 128.7975 volts? I'm asking this because I am willing to change both the driver and power supply, but need to know what would be both relatively safe...

I had planned on using +12v on the + rail and -12v on the - rail, done this before to get 24v. But bmac2 is correct only 1 amp on the -12v rail. Given the stepper specs this still might work. PS original usage was to build live steam parts.

I'm not using pololu drivers, I'm using the stepper driver based on the Toshiba TB6560 chip. The data sheet says voltages above 24 volt isn't recommended. The ATX would give me 24 volts across the +12 and -12 volt rails, unless I can't do that with an ATX power supply.

I have a question,would a 250 watt 12 volt ATX power supply have enough amps to power the electronics package and a nema 23 57BYGH310 stepper? ATX: Dell HP-P2507F3B 120v 6a input 5v 22a output 3.3v 18a output 12v 14a output 24.0 kg-cm (333.2 oz-in) 4 Wire NEMA 23 Stepping Motor; Step...

I know this is an old thread, but it was very helpful to me when I turned my ER32 collet chuck for my Atlas 618 lathe. I had the armstrong spanner, so I turned the OD to fit. It turned out to be 2" diameter and just over 3" tall. The resemblance to the chuck by majorstrain is intensional...
