Being minimalistic, you would only need a hand saw, knife, drill and a screw driver. Although a knife, smal hatchet and a drill would also suffice. For bending wood you would need a fire. you don’t really need a steaming device, just the heat.
For easier and possibly more accurate building if you’re not a craftsperson, you would also need:
- band saw
- table saw
- electric planer (elhyvel)
- plunge router (överhandsfräs)
- electric drill/screwdriver
- shallow angle hand planer (the smaller one hand version)
