How about building an electric guitar? I made one when I was 17. It does require some special tools. Stewart Mac is a great resource for information and parts/equipment. Check out their book. https://www.stewmac.com/luthier-tools-and-supplies/supplies/...

Building a fender-style guitar first is the easiest route, especially if you use a double-truss neck rod (get it from Stewart Mac). I recommend buying a pre-cut fret board as well. Also, you can use tung oil instead of clear coating. Trying to do an opaque spray job was my biggest regret. I could have oiled my beautiful mahogany body with much better results.

Tools:

* Flexible edge (for pegboard and body profile https://shop.pacificarc.us/products/flexible-edge-curves)

* Bandsaw (body and neck shape)

* Drill Press

* Router (For the neck and body cavities)

* Thickness planer (only need this once to plane the body wood before gluing)

* Curved carving knife (Like this https://ramelson.com/product/curved-hook-carving-knife/) to profile the neck.

* Pipe clamps

Nice to have tools:

* Oscillating spindle sander

* Belt sander

* Router table

I recommend using an easy to work wood like maple for the first attempt. I found mahogany to be a lot of effort to work. Expect the project to take quite a wile. I think mine took 200 hours.
