David,
I saw a photo of how it was done. After the holes were milled in the cha instay, a sheet of thin steel was formed to fit the hole and inserted th rough the stay. Then some thin steel rolled into an expanding spring-lik e coil was inserted to hold the thin stock against the edges while the s heet was tacked in place. The coils were removed and then the finish bra zing was done. Pretty simple once the holes were milled in the stays.
The purpose was to add some truss to the chainstays, according to Albert o Masi.

Balsa wood?
I can imagine shaping a balsa plug to fit the inside of the tube and
then after the tube has it's holes inserting it and then cleaning out the
exposed wood, sealing and painting.... But looking at the shape of the tubes I'd
expect that it would have been pretty hard to get them in there. And
looking more closely I can't see any tubing edge...
Maybe the goal wasn't weight loss, but strength. Those could be sections
of tube that have been squashed and brazed into the holes....
I'll stop guessing now!
