There have been a few replies to your call for help, none which I
thought were really helpful.
I have given it some more thought, along the lines of, what would i
do if i was in your position and wanted to emboss metal? with a
Well, roll embossing/ coining can be done but you need the right
tool for the job which regrettably you dont have…
As you havnt mentioned
the thickness in thous
the thickness of the brass etched plate
and the size, width and length, its more difficult to give a precise
Now Ive been minting and embossing for at least 20 yrs with tool
steel dies and the right machinery so know what you need to do. When
rolling metal it tends to curve up, ie not come out straight, so a
mill isnt the best way to to do the job apart from other technical
What you need is in fact an engineering solution to what put simply
is metal bending.
This doesnt need anything like the tonnage, yes tons!! of energy to
make the metal flow like in coining.
You need to make 2 brass plates, one the negative which you have
already AND a positive of the design both the same size, at least
3/16th in thick.
Then you put your silver between the two and squeeze then together,
evenly all over,ie a 1/2in steel plate ontop and below.
The easiest way to do this s with a car repair shop hydraulic press.
Youll need to ask a local car repair shop to do it for you, your a
girl!! so smile!! and they will probably do it for free!! The press
needs to be over 10 tons of load ability.
You then takethe sandwich out of the hyd press, have a look and see
how it has come out.
It depends on all sorts of things like depth of embossing, clearance
between the etching of the 2 brass plates, there needs to be enough
space for the silver toNOT be sheared by the brass etched edges. Hope
Also how many of the silver items you plan to produce for the
product,10? 100? 1000?
this is in addition to your artistic design, pricing marketing etc in
making such a product.
Thats why Ive always advised young folk to work in a manufacturing
silversmiths workshop. Theres no substitute for learning from the
Now getting back to your mill, IF you explaind in detail what you
wanted to do and your mill supplier said it would do the job, it
obviously wont so you have a good case to return it for a refund. you
need to give that a try.
A mill could do it but it would need to be much bigger with rolls
reduced in size to have enough clearance for the 2 brass or steel
plates as well as the silver and still have the gears mesh properly.
In other words get Durston to make you another set of rolls to do
specifically what you want. They will of course be useless for
normal metal rolling.
More on powered rolling another time.
Let us know how you get on.
