Being minimalistic but modern, you would only need a hand saw, knife, drill and a screw driver. Although a knife, small hatchet and a hand drill would also suffice. For bending wood you would need a fire. You don’t really need a steaming device, just the heat. It is pretty convenient to attach a pipe to your teapot and build a steambox though. It also makes for a more consistent result without so much guesswork. A hand held electric saw for ripping wood will come in handy. A cheap one will do the job.
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)
