🦋 Tin-can Cello: bracing the washtub
Since I started designing the tin-can cello, I've been going back and forth about whether (and how) to add bracing material. It's a washtub! I would think, Designed to hold hundreds of pounds of water without deforming! Well, sure, but the stress from the cello strings will be in a different direction...
This morning I think I figured it out. I added two pieces of bracing wood, one on each end of the dowel. The tail end brace, pictured above, locks into the dowel's taper, and is very stable -- this corner is where just about all the stress on the bucket will be, it's where the tailpiece butts up against the bucket. The head end brace is just a square of wood tucked between the dowel and the rim of the soundboard, meant to keep the side of the bucket from buckling.
