Anything that starts life as a piece of framing lumber qualifies as Caveman Carpentry. Here’s a double bass stand that I made. I got the idea from Jake de Villiers, who runs The Bass Spa in Vancouver, BC. He had an example posted on one of the TalkBass forums.
Since it has to live in my great room, I wanted it to look at least half decent. I used a less-than-shabby pine 2"x10"x8' for the stock. Cut it up, screw it together. Countersink and plug the screw holes. Sand, stain, seal with danish oil. Glue cork on to the contact surfaces. Caveman carpentry at it's finest!
Errors / things that needed tweaking:
1 - The board I picked out had good grain and was nice and straight, but turned out to have a slight cup That made the build-up more challenging and the end product look slightly more, umm, "rustic". Live and learn.
2 - I'm 6'0" tall, and play with about 7" of endpin out. If I had made the whole thing just 1" taller, I could just drop it right into the stand without having to stop and adjust the end pin first. Sometimes it's that extra 30 seconds of putzing around that stops me from just picking up the bass and playing for a few minutes on a whim.
Remedy: install those little elevator blocks on the bottom. Inelegant, but still not shabby.
