[QUOTE="Wishfull, post: 322738, member: 7460"] Not meaning to hijack this topic but can you expand on the acid hardening process ? I have made my own pick from a plow disc. Not that easy to find second hand anymore. Cutting the shape out even took a good while with an 8 inch angle grinder with a cutting disc. I would have made a handle and was going to out of the local Eucalyptus Porosa and very hard fine grained timber but no access to a wood lathe. So I had to source one from eBay but couldn't find any that were actually had a round crossection just oval ones. Anyway welded a slightly flattened round tubular section onto the cut out head put a heap of Gorilla glue into the tube, put the handle in thena cut to length roofing teck into the predrilled hole and did up tight. After the glue set trimmed of the excess expaned glue. Sharpened the point slowly on a grinding wheel dipping in water to cool very often and then the srapping end. Painted the head black and most of the handle with bright orange marking paint. I have been told that it is easy to loose a pick in the bush hence the paint colour. The one I made has an18 inch handle 950 grams total. I also have one for Mrs Wishfull that is 850 grams and a larger Walco pick that is 1.8 kg with a 750 mm handle which isn't something you want to lug around all day. Please excuse my changing from metric to imperial I was brought up with both but I'm mostly an imperialist. Cheers. :Y: [/QUOTE]
