@Stuart Munro 1 - I thought those "Stanley 20-800 Adjustable Angle Clamping Mitre Box" do look interesting. But can they cut steel? At a quick look, I thought that they were only for wood, no? IF they can cut steel then they DO look useful but they won't allow me to cut sheets of material (plust they are a fraction bulky... and won't be able to cut very thin stuff...) Been doing some research. My saw is a Nobex bought 25 years ago for picture framing. It has not changed but is rather pricey. The Stanley is much better price. Mine takes a 630mm blade, the other Nobex size is 565mm.
