Cutting Sheet Copper

    My brother has just messaged me this. Presumably to do with the niece's arts and crafts:

    "I'm going to be cutting copper sheet. Usually 1mm or less thick but possibly up to 3mm occasionally. Not long cuts and usually no more than taking 6" strips off larger sheets but now and again cutting shapes out. What do you think of the Macallister MSMS500T. mini circular saw? £30 from B&Q but happy to spend more if that doesnt look good enough"

    1mm...a bfo pair of scissors surely? 3mm a jigsaw if shapes?

    Any thoughts?

    Cheers

    Copper too soft and gummy for a jigsaw.

    1mm-3mm you could use a Beverley Shear.

    1mm may be possible to use a set of tin snips.

    Nibbler as above. Lots of horrible little bits of lethal swarf in your socks for weeks though, if you’re not careful.

    The problem I find with the MM cutter linked above is the damage inflicted by the knurled wheel, I imagine it will be worse on copper.

    A Beverly knock-off would be perfect for this, I think Baileigh and WNS sell them.

    The shears are ok when set correctly for straight cuts, but you cant easily cut curves. You can get away with big external radiuses but not internal. Anything tight you would be restricted to lots of short little straight cuts then finishing the curve with a file.

    Apparently my brother has decided to take up silver smithing but wants to practice on copper.

    If he's is not intending cutting anything thick (3mm silver might get a bit costly) an EDMA hand nibbler is worth a try.

    I didn't have any copper sheet but tried my set out on some scrap 22mm copper pipe and it works a treat.
    All the cuts in the photos were carried out with the hand nibbler.
    The curve I cut in the flat copper is about as tight as you can get with out risking breaking a blade. (about 3 inch diameter)

    They are great on mild steel as well, but as said it easy to snap a blade if you get too enthusiastic.
