  1. Thanks very much to all who responded. The CLAG article, for which Michael has provided a link, was certainly the one I was thinking of, but I had not come across the Colin Binnie notes, which are both useful and amusing. I do have Olfa cutters, to which John has referred, but I want to try to achieve slightly different results, and will experiment with the angle suggested by Colin Binnie as well as the right angle specified in the CLAG article. The late John Hayes, in his excellent book on the 4mm Coal Wagon, shows the scribing tools he made from old machine hacksaw blades, and also a tool for cutting components from brass etches. I have had a go at these, but they do involve some pretty heavy duty grinding. I'm sure that George Slater's method, mentioned by Nick, also works, but I think that the cautionary note in the CLAG article about grinding off the sharp edge of the scalpel blade first makes sense for anyone as naturally prone to daft mistakes as I am. Thanks again for your help, and taking the trouble to respond. George
  2. Some time ago, I read a short article on adapting a used Swann Morton No. 11 scalpel blade to make a fine line scriber - or squawker - for plastic sheet. Of course, now that I want to try it out, I cannot find the article. Can anyone help me to locate it? It involved grinding the blade to re-shape it, with the use, I think, of a disc in a mini-drill. Many thanks. George
