Not too long ago, I bought a wooden doming block (from Magpie Gemstones, of course!) because I like the look of domed, curved metal - and to tell the truth, a new tool is always a great thing!
I had some old pennies (the pennies from 1982 and earlier are the ones to use, those minted after are only a covering of copper over a base of zinc) so I started with those. I found some information on the internet to guide me along on this journey, and got to work.
I found out soon enough that the lip along the outside of the penny is heavy and although not a seam, it is thicker at the edge - and so because my doming block is wood, it created ridges in the curves and now my curves have dents. Will definitely have to upgrade to a metal one to do more pennies.
I also experimented, using other things to pound with besides the wooden punches that come with it - they work great but I was just looking for some other tools that I could use. I found a couple of bolts with round smooth heads, one was about 12mm and the other one was about 20mm. I used the bolts on some pennies instead of the wooden punches and, as you would suspect, using the steel bolt as a punch worked oh so much faster than using the wood. So I found two 1963 pennies, domed them, drilled a hole through each one, wired up some freshwater pearls and some green stone (I got them from Magpie Gemstones - I am not sure what the stone is I got it in a multi-stone rondelle strand) and then crafted a sterling silver (with a coil of thin copper wire) earwire and, there you go............"My Two Cents"!!!!!!!!!!
