May I suggest that you paint the OSB while it is on the sawhorse ,easier and faster than after it is on the studs, at least the first coat, it soaks up paint like a sponge.
That TS would probably run on 220v. Mine did,and what a difference, never blew a breaker during ripping after that.
My current Craftsman 12" direct drive table saw runs on 220v. too and never has blown the breaker ripping.
Forgot ,like Chuck mentioned you will want a dust collection system too that will require 220 v.
Without a ceiling too you can always run overhead with the 220 v. an drop where the machines are located.
