A Rolling Mill is an excellent tool to add to any Jewelry Workshop.
For care and maintenance you need to keep your rollers protected
from rust. Some Jewelers like to use a sponge attached to the upper
part of the mill, soaked in oil, so it touches the upper roller and
leaves a coating of oil.
I prefer to use Petroleum Jelly. I use a paper towel to apply the
Petroleum jelly to one of the rollers. With the two rollers in the
closed position I roll the mill to allow the Jelly to coat both
rollers. When I am ready to use the machine I simply take a paper
towel and hold it against the rollers while I am turning the mill to
remove the excess. I then recoat after use.
My Mill is about 25 years old and I have had it in Humid as well as
Dry Climates and I have never had a problem.
If you have a machine with a reduction gear you will need to check
it at least every year or so and grease it if necessary.
As for rolling your texture onto sheet, almost any gauge sheet that
would be appropriate to do the bracelet will work ( that is 16 to 22
gauge ). Make sure that the sheet of metal that you want the design
to transfer to is annealed, pickled, cleaned and polished. Place the
watercolor paper between two sheets of metal and roll. A very simple
process that gives interesting results.
