Hi everyone! For this instructable I want to show you guys how to make a plywood upright bass. This was my biggest project for my senior year in high school and was the project that I took to compete in the 2012-2013 SkillsUSA district and state conferences. The main objective was to make a functional upright bass out of any material I could find locally which where I'm from, is not a lot. In all honesty, I did not think that my bass would work but I can proudly say that it sounds perfect to me, it may not be as good as those really expensive models but it can definitely hold its own ground.
Step 1: Tools and Materials
Tools I Used:
- Mitre saw
- Band saw
- Belt and disk sander
- C clamps( I used about ten 2 inch clamps and two 4 inch clamps but the more the better)
- F clamps( I used a good 8 of them)
- Drill Press
- Drill bit set
- Table saw
- Heat gun
Materials I used:
- One 1/4 sheet of plywood(for the top and back), can be any kind you want. I believe I used maple.
- One 1/8 sheet of plywood(for the ribs), I used lauan plywood though I highly recommend you use really bendable plywood like bendyply. I tried looking everywhere in town but I couldn't find anything so I had to go with the lauan plywood.
- One 3/4 sheet of plywood(for the mould), you can use any kind you want, it doesn't really matter it could even be MDF.
- One 2 x 2 x 8(for the corner blocks)
- One 2 x 10 x 10(for the neck, can also be used for the tailpiece)
- One 2 x 6 x 10(for the neck block, end pin block, can also be used for the bass bar)
- One 1-1/4 x 4 x 33(for the fingerboard). To get this, I cut a stock of oak that my teacher gave me, unfortunately it was short by about 2 inches so I added on to it, I will make it clearer on the fingerboard step.
- One 3/4 hardwood dowel(for the soundpost, can also be used for the end pin)
- Very thick string(to connect the tailpiece to the end pin)
- A strong wood glue(when making string instruments like the violin, cello, upright bass, etc. it is essential to use hide glue to make them but I chose not to and I will explain later on in the steps)
- One 1 x 10 x 1'(for the bridge)
- Tuning gears
- Upright bass strings
