I am an enameler and my metalworking abilities are limited. I can
saw pretty well, soldering basics and so on. I make my own settings.
My equipment is also limited.
For a project, I have to make a copper cylinder, 2 mm thick (a must)
and about 4.5 to 5 cm in diameter. I want to make this from sheet,
to be able to saw the intricate designs first and then solder it
closed. I know it is not going to be easy to curve such a thick sheet
into as perfect a cylinder as I can. I will have to conform to a
precise outside and inside diameter (just don’t know exactly how wide
yet, this will have to fit around a wooden box).
The length of the tube I still have to decide. I guess the longer it
is, the more difficult it will be to form it. I was estimating
between 5 and 7 cm long.
I have a ring mandrel, which of course is tapered, and a good big
boxwood hammer. The biggest measurement of my mandrel will most
likely be too small, but it may help for shaping.
I am thinking I may need a wooden dowel of a slightly smaller inner
circumference as well? the wood turner that is making the box for me
can make one to my measurements, of hard wood. Or I may find a pine
wood dowel of approximate measurements in the hardware store.
I see a lot of annealing in my near future.
I may have other problems afterwards with the solder and the enamel
and possible tension deformation, but that is for later…
Any advice would be greatly appreciated.
