As Gert hints, $340 including tailstock via Ebay

The caveat here is going to be your controller. Are you using the original 3G controls or did you upgrade to a 4G board or RBK? If using the original 3G controls, you need a motor less than 2A or you'll kill the driver. Something like this should bolt right up (check shaft sizes) and be under 2A: NEMA 23 Motor

Brady, how would the eBay item you linked to work with a 2009 PRSAlpha with 2.2hp spindle?

The old board was DOA and tech support suggested replacing it with a v4g board. I installed it about a year ago.

You'd need to adapt an Alpha motor and drive to the mechanicals...not quite as bad as it seems.

You are good to go then up to a 3A motor without additional heat sink. You'll need an accessory motor cable, extra matching Gecko drive if your Acc slot is empty and change the current set resistor to match the motor.

I found this on Amazon, but I don't se an amperage in the ad. There's others that say 3 amp, but they're 3 jaw chucks. I sent a request to the seller for more info. Where would I find a accessory motor cable? Is that a standard cable or is it propriatorey to ShopBot? I'll have to look to see if the 4th axis slot has a drive. I thought it did when I installed the board, but that's been awhile, might just be wishful thinking.

There's no tailstock included with that...Think about how you are going to mount the indexer, then decide on the hardware. I found that buying a lathe with extension bed was cheaper/better than buying one of those things off Ebay. Then choose the stepper motor you want and belt reduction to the lathe shaft. If there isn't a drive in the 5th slot, just buy another matching Gecko. Same model as the rest of them.

You can get a PRT style Acc cable from SB. It has the 4-position Wago connectors on each end - plug & play. Get an extra motor side connector.

There's a little work involved, but nothing too serious. If you just want plug & play then you have to pony up for what SB sells them for. Otherwise you have to educate yourself and then work through it.
