Just put a 220v circuit in the shop and be done with it.

A transformer will not be practical. To handle the current draw of the motor it would be bigger than the motor, will loose a portion of the energy it is converting to efficiency loss and will cost way more than the saw. The transformer someone linked to on eBay was a 100va. That would be overloaded running a 100 watt light bulb. You would need at least a 3000va, probably more, to run a 12” saw which probably has a 3 or 5 hp motor in it.

Even if you have a motor that can be rewired for 120v the rest of the saw controls might have to be rewired or replaced to run on 120v.
