Lubricant for the Connecting
Rods - Charles Darley
I am currently building the 20-note organ and have not seen any reference
to the lubricant that should be used on the moving parts. Can I suggest
that the talcum powder that is used with the pipe stoppers is also used as
a lubricant as it is a natural slip surface that will bed well into wood
and coat it rather like a "Teflon" covering.
Just apply a little to the wooden surface wherever they are in contact with
the metal craft. I have tried it and found it very successful.

Improved Driving Wheel - Charles Darley
Instead of using emery cloth for the driving wheel, I have used a 3M product
"Premium Paint Removal" P80 grade, available from B&Q. This is a coarse
sandpaper-like material with a paper backing. It sticks very well to the
card drive pulley using PVA glue. The picture shows that the joint is a diagonal
one. The result is that there is less likelihood of the material lifting
than with a simple butt joint. |
