Good question, and depends a lot on how you want to build it. So I'll assume hand tools, and I'm bring the set I used to build mine as well. Saws, for breaking down stock 1 cross cut 1 rip, for jointery 2 -12inch back saws 1 cross cut 1 rip, a coping saw. Hand planes, #5, #7, #4, block plane, router plane, spoke shave. Drilling, a bit brace with 1/4" auger bit, an egg beater drill with a 3/32" drill bit. Chisels, 1/4", 1/2", 1". Rasps files and a card scraper will come in handy. Marking and measuring, a ruler and tape measure, a square, a marking gauge, a mortise gauge, a marking knife, a bevel square or gauge, and a pencil. Other tools are saw benchs, bench hooks, and a shooting board. I hope I didn't forgot anything, I think Bill said he had the kitchen sink down there already. I do hope this helps and I look forward to this project.
