Rolling mill hints

Jewelry Discussion
21

I have a Durston combination mill and have found it to be money well
spent. I probably can’t afford another terribly soon so I find it
makes sense to be careful with it.

I anneal often and I take small bites. I don’t run ferrous materials
through the rollers. I use quality lubricants on the rollers and I
am careful what I roll.

One of the issues with the Durston that upset me was I read here
after someone posted photo's here of badly marked rollers that one
shouldn't roll wire through on the flat section of the mill or it
would leave marks because the rollers are not solid all the way
through, they have an outer casing over a somewhat softer core. I
had rolled many a heavy wire through the flat part of my Cavallin
with nary a hint of trouble.

My question was if anyone could comment on this alleged Durston
problem. (I already know we should stick to ferrous metals on our
mills…:-)…)

Thanks for any input.

I have owned a Cavallin mill for many years. It was a good mill.

If you want a Great quality mill than get a durston If you don’t want
to get a great quality mill, get a cheap mill. You get what you pay
for.

I personally own a Durston mill. I have found that the quality is
exceptional and the Durston mill is smoother when rolling, which
tends to give me better quality material when I am done.

Next: Ferrous are metals and alloys containing iron; non-ferrous
materials do not do not Ferrous metals include mild steel, carbon
steel, stainless steel, cast iron, and wrought iron.

No, you should Not run Ferrous metals through your mill unless you
ensureyou have protected the rolls on that mill. There are ways of
doing this.

Ferris metals usually contain iron and are not usually safe in your
mill.

One exception would be the Bonny Doon texture plates.

The Bonny doon texture plates are designed to be run through your
mill without damaging your rollers.

Otherwise you should stick to gold, silver, copper, brass or
standard jewelry metals.

I have never had an issue running jewelry metals through my mills,
Durstonor otherwise.

You can damage any too if you abuse. Stop by my workshop. I will
show youa few.

I can break or damage almost anything.

If you use your Durston mill correctly, as intended, it will perform
flawlessly. Abuse it and you will damage it.

Read about your mill and learn to use your mill correctly.
