My plans for a productive evening of xylophone-building thus foiled, I turned to slapping together the rest of the frame-mounting hardware.
Unfortunately, the Hollaender company turned out a couple of SpeedRail parts with nasty burrs inside that kept them from sliding onto the 2-inch aluminum tubing that we’re using for xylophone frames.
I tried grinding out the lip on both sides of the mount …
But no luck. The collar still wouldn’t slide on over the tubing …

In machining – as in lovemaking and war – if it hurts, you’re not doing it right.
I seem to keep making the same damn mistake. alienrobot did a great job of tapping most of the mounting holes in Keyboard 1 using just the little 4-inch tap handle that came with the set.
Then I got all clever, applied excessive leverage and snapped a tap off in a hole by using too much leverage. It came out with a pair of pliers … but then I did it again.
And I just did it again tonight. Here’s what it looks like from the back.
Opinions on the CrashSpace forum ranged from “A high-end machine shop will need to use EDM to burn the tap out of there” to “Yep, you’re fully fucked.”
Guess I’ll go look up a machinist. And hope I’m not fully fucked.
Random, random, random!
We flit from project to project, looking like hummingbirds on crack (one day it’s instrument construction, the next day body work), but we’re still on a headlong parallel-tracked trajectory to getting the beast ready for Maker Faire.
FORWARD! IN ALL DIRECTIONS!
We did a lot of unfinished business today, (not all of it documented here).
I cut and drilled the stringers for Keyboard 3.
@alienrobot and I bolted down the main mounting clamps for Keyboard 1. We bought a double fistful of bolts, nuts and washers for attachment of the mounting hardware for Keyboards 2 and 3.
And then we got busy installing the rug and putting the seats and doorsills back in …
