Last spring, I used a 3D printing service to make register top and
bottom guides 1 mm thick. Since they charge by volume, box guides would
have been out of budget. I had to make three trys to get the holes
right, because the system wasn't that accurate.

I put one set of samples in the boat spinet and they work. I will use
the others in a carbon fiber ultralight virginal using the same
keyboard, but 3 semitones shorter, so I can toss it in the back seat of
a rental car. I don't know what it will sound like, but it will be loud,
from the behavior of the sheet stock.

When the portable is complete, I will report my impressions, and perhaps
Dong Sok will try it and report his, if he feels like it.

I am many years retired, and will never make another instrument for a
paying client, so this is entirely academic.
