Welcome Brian, I started my wood working in a 9 x 10 garden shed in my back yard in Humble, Tx.... I had a full sized lathe, two scroll saws, a table saw, a 9" band saw, drill press, my work bench, plus my garden tools, lawnmower and what ever else I could cram in there... to use the table saw I had to move it outside into the yard, the lathe was on wheels so I could take it out, had to move the lawmower outside, if I needed to change my mind, in order to have room to do so, I had to go outside... had a lot of fun and made a lot of pens.... after moving to TN, I now have a 12 x 24 shop with all those tools plus chain saws, a 14" band saw, three work benches, a work bench mounted belt sander, a slow speed grinder to sharpen, a high speed grinder, two racks for wood storage, a compressor, dust collection is in separate closet that looks more like an outhouse attached to one end of the shop, my chop saw, planer, jointer, router table and an upside down saber saw from Rockler (I regret spending money for as I rarely use it) plus anything else I think I might use... small shops work fine, depending on how they are organized...
You are gonna have lots of fun.... as I often tell customers, wood turning is the most fun you can have with all your clothes on.
