You might be able to do all this with simple hand tools, but using the right tools make the job easier. These are some of the tools I use to make my DIY drum kits. I pretty much bought the cheapest power tools I could find and they work just fine.
I have used the band saw to cut foam blocks, wood drum mounting brackets, and many other small cutting projects. The smallest band saw works fine.
A drill press is definitely needed. The drill press will keep every thing straight and inline. I tried using a hand drill and it doesn’t work. It is very hard to drill straight with a hand drill.
Makes nice quick straight square cuts. With a metal blade, I have used it to cut aluminum bars.
Table Saw I have used the table saw to cut drum shells in half. A jig saw or eve a hack saw blade will also work, but the table saw is quick and makes a nice straight cut.
Router Circle Jig
The Router circle jig works great for cutting the wood drum hoops. It will cut perfect circles.
I used this tool to make smaller drums out of the buckets.
I have also use the jig saw to cut drum shells in half. It’s hard to get a nice straight cut, but usually the rubber hose trim will fix that. I mostly use for cutting the buckets.
