Although you will get different advise from everyone, my advice would
be to get the widest COMBINATION rolling mill Durston makes, with
both grooves and flat rollers, and make sure your mill has removable
side rollers for making half-round stock, if you desire. With this
machine, you will be able to make all your own stock, as well as
modify all existing wire and sheet stock (wider, narrower, thinner,
longer, etc.) It’s the most versatile and practical machine you can
own for metalsmithing. An exclusively flat rolling mill is severely
limited to just thinning out sheet stock, and it does nothing else. I
would definately go for the combination mill, unquestionably.
Concerning the hydraulic press, you will get a lot of other advice
about this piece of equipment as well, but I believe you will use
that press about 1/20th as often as you will use your rolling mill.
Sure, I’m a make- it- yourself type guy, but our 2 rolling mills in
our UCSD studio get a lot of use daily, but our hydraulic press gets
used about once or twice a week.
