Hello, this is my first post to the forum I’ve been lurking on the
website for a while. I have come into possession of an older
Cavallin hand rolling mill from the estate of a jeweler. I’ve used it
but a handful of times and have been trying to figure out a gritty
feeling it has. So today I managed to open it after having a mechanic
help loosen the nuts and bolts on the outside of the handle. The
external gears were coated in a thick heavy grease the gears in the
gearbox however have only a very fine oil coating that rubs off gray.
I am having a machine shop clean these parts but I am wondering what
is the best way to clean the inside of the gearbox and what is the
best grease for the outside gears and the best oil/ grease for the
gearbox. I am assuming that it would be a great in the gearbox as it
does not have rubber seals or the place for said seals. Just a small
ball bearing like fitting for filling. Thank you for any help you
can give me.
