Them machine's and riggy up's would be a waste of time for some of the coin's i have had to split..i can just imagine trying to pick a 10stone 3ft round coin up and splitting it with any of them contraption's.. ..your back would be fooked at the end of the day..and them little log's that they are chopping in the vid could be done with a butter knife.. ..
I think i will stay with the bottom one of these two and use a bit of muscle power and sweat.. unless i go into the business selling log's..
