I just finished building this marimba for my younger son, who plays in his school band and competes at competitions. Very challenging project, but very fun. Back in April, this was just a pile of wood and a stack of aluminum tubes.
The keys are padauk. The base is a mixture of hardwoods. Metal unistrut rails hold the upper rails that support the keys. Rubber is used to isolate these so the metal doesn’t resonate during play. Hockey pucks are the knobs at the ends that can be loosened and tightened to change the height of the strut assembly up to 8 inches.
The resonator tubes are aluminum. These were priced great from metalsupermarkets.com but were rough as supplied. Surprisingly, they easily polished up to look like shiny chrome using 150-220-400-600 grit sandpaper followed by 00 and 0000 steel wool followed by Mother’s aluminum polish.
The mallets shown were made to use during the build to tune the keys and resonator tubes so that good mallets would not get ruined. These mallets were fast to make from superglue, a couple pieces of dowel, rubber chair leg caps, baby socks to wrap the ends, and electrical tape to hold the socks on.
