Hi Gordon,
I've always been a fan of VJ lube ever since I made my jar of it about 20
years ago. It would do the job for most of what you asked about. However
there are other newer more expensive options that I would be remiss if I
didn't mention. For the dowel ends to "shoe leather" if you don't have VJ
lube the Super Lube grease is an excellent choice, it has Teflon in it just
work some into the leather. In addition you could spray the end of the dowel
with McLube which has teflon & molybdenum and will adhere to wood or metal
and will not rub off. I would also use the McLube for the dowell where it
passes through the bushed hole in the keybed, it is a permanent lube like a
paint, very similar to the dag on bridges. For your hinge pins in big bushed
holes, I would spray the pins with McLube and pack the bushing with Super
Lube. For the metal to leather Super Lube and the same for your metal pins
inside the lyre base, unless you want to spray them with McLube.
The one thing you do HAVE to keep in mind is the McLube spray shouldn't be
sprayed indoors, you will need to take the trapwork outside spray the
necessary parts and give it about 5 minutes for the fumes to evaporate prior
to returning it inside and re-installing.
Plain old teflon spray will do the job as will Protek but only for a while,
what I outlined above are more permanent type fixes that should last much
longer. They will, of course take a little longer to do but if you can be
assured of not being called back in the near future for this same problem, I
believe it's worth it.
I hope this helps,
Mike
