How about something like this, a 12" metal shear, roller and brake all in one. It would do a what you want and more. This is a Eastwood brand. They are sold under many different names and with a big price spread. Just do a web search for " 12 inch 3 in 1 Metal Fabrication Brake Shear and Slip Roll"

Re: Mill Question - should I? or shouldn't I
You need to get into investment casting of precious metals! Lost Wax casting would let you make your model in easily carved wax, then you sprue it, and invest the model. Then you take the invested model and burn out the wax, and pour in your metal of choice to fill the mold and sprue... Let it cool a bit, then wash the mold off the metal casting and finish it.?
Local friend of mine makes model train parts in stainless steel using this method, but he sends the models out to be invested, burned out, and cast. For one-off castings, you can use the original model, or you can make silicone molds to make multiple copies of the model. Here's one source of info:?? And I have both of the books from Sharr Choate:?? and more general books on lost wax casting:??&??I have both of those in digital and paper copies, too.?
Then you can be just as easily distracted as I am! ;)?
Back to shears for a moment, too!?
I have a shear similar to this one, though my local tool shop was selling them for about $30 a while back.?
For doing miniature work like you do, this one might be more appropriate:?

Re: Mill Question - should I? or shouldn't I
Hello
Tamra:
Are you
making 50 tools, or 50 slips of copper?
The
tools look like they were made by a wire EDM and would be hard
to make even one on a Unimat.
50
slips, I would cut them oversize, clamp them in a stack with
two clamps and then mill the edges including the corner
radius. This way you could control the size and they would all
match.

Re: Mill Question - should I? or shouldn't I
depending on thickness, I cut steel shimstock up to about 10 thou with normal scissors, brass too, so cant see why copper should be much different. As for holding thin stock, thats best done by stacking several sheets to a thickness you can hold and accurately work.

Recently, I did an experiment to see if my Cricut Maker3 that advertises it will cut 1/16" basswood, would cut 1/32" oak veneer.? It failed.? I'm 100% sure I can cut veneer on a dremel, preac or micro mark table saw.? (Well if I would go look for the micro mark table saw, but it is still cold to be in the basement too long.)?
I should actually try and see if the Cricut will cut basswood, all that you do is tape it to the mat, and load the pattern, turn on machine and press cut, but I can't seem to concentrate long enough to do this task... traveling to the world's largest miniature show next week!
Friend told me that I did not want to cut real sterling silver with my table saw as I would loose silver to saw kerf, but the cost of copper is not nearly the cost of sterling silver.? I will reclaim my silver, I have a kiln...
I have a couple of projects that I would love to create in enamels, like a fireplace screen in miniature, or lampshade.... and OMG,? some stained glass windows! so I'm thinking of making these palettes, myself.? (I did actually attempt to enamel a silver vase, many years ago in miniature... this clearly will require some practice) flat surface, much easier to control.

Re: Mill Question - should I? or shouldn't I
Tamra, ? Unless it has been hardened, pure copper is quite soft and sticky (like pure Aluminum).? It will snag and clog saw blades, especially powered saws.? ? If the copper sheets are thin, why don¡¯t you just cut it with sheet metal shears, or a paper cutter??? ? Just a suggestion. ? Jerry F. California ?

Subject: [Unimat] Mill Question - should I? or shouldn't I? Before I assemble my unimat as a mill, can I mill this shape qty 50 rectangles with a unimat?
1-3/8" x 7/8" and 1- 11/16" x 1"
My friend has been making jewelry maybe 4 years now, specializing in enameling and she used a disc cutter to create her enamel palette...
(which is firing the enamels on copper over white flux, plain copper, silver foil, gold foil, etc, etc. to see how the color looks before you use it.)
This is likely a CNC? operation, as clearly this is very repeatable with a CNC.? Me being me, thinks 20 gauge or 24 gauge copper is extremely thin and I don't understand why I cannot cut it with a table saw?? Clearly, I know I can cut 260 brass with a jewelry saw and my own hand.? Surely a table saw is practical and fast?
I am missing something, of course the cool tool folks have every right to sell die cutters for $144, but I got these cool tool...?!??
It is probably more of an issue of how to hold something so thin, and not messing up what is holding the not even 1 mm thickness of copper or sterling.

Re: Mill Question - should I? or shouldn't I
Kevin, I think this is a much safer solution... I have one that I use all the time at work.? I will order the copper and see if I can cut it with it;? I do have a few saw blades from my micro mark table saw.... oh, and looking this up, they do indicate you can cut brass up to 1/16".??
.
Lots of options here....
Sometimes, I wish for a real metal cutting bandsaw for steel, but so far, one has not landed in the shop.? I am not permitted to use dear husbands woodworking tools on metals... that will get me kicked out of the shop; but I can do this on my micromark table saw if the paper cutter doesn't work.

Kevin Groenke @ PersonMakeObject
Hey Tamra, I'll cut 1/8" and thicker non-ferrous metals on my tablesaw any day, but thinner stock is sketchy because there's only one tooth in the material at a time. Some time ago I had to cut some copper and recalled the paper cutter I had used a few minutes before. ??, that's like a metal shear I realized (duh!). I would think with some creative fixturing, it would be pretty easy to cut your 20-24ga copper quite accurately and efficiently with a simple guitilline style paper cutter. If you don't have one, consider this a great opportunity to pick one up and I assure you will find a myriad of uses for it. Cheers and make on!? -kevin

Re: Widening an existing hole with a drill bit: how to guarantee concentricity?
If there is already a center hole, I just use an endmill.? A drill bit will grab and go off course.? An endmill in a drill press/mill wil give you a perfect hole exactly where you tell it to be.

Re: Widening an existing hole with a drill bit: how to guarantee concentricity?
Since my last message didn't? contain John Hutnick's suggestion to trade the 12mm chuck for a 14mm chuck, I'm going to chime in on that again. Make a trade! :)

Re: Unimat 3 alignment problem?
Hello:
What are we looking at in the photos with the indicators?
Let's see if I understand what you are asking and remember exactly what I did. 8^¡ã Started with a piece steel recovered from some kitchen thing that went south, (manual juicer?) which at that time I roughed to ?~20mm. Chucked it, put a center on the far side and cut the 35mm piece on the lathe, faced it and took it down to 19.5mm before turning it around. Chucked it again checking it was properly aligned/centered with the dial, faced it and I then took 20mm of it to ?12mm.
Thanks for your input.? Best, JHM
