113 forum posts | Oh!!! for a decent Tool & Cutter Grinder. I looked at a few designs and ideas in ME & MEW also H Halls, all seem to have some limitations and easy of manufacture. So Graham Howe, was good enough to point me in the direction of MaryPoppinBag on the E/bay site, where they sell all sorts of goodies,One of these is the CD on tool& cutter grinders, which has the complete manuals of many industrial tool sharpeners, More importantley it also has 65 pages of drawings and instructions for the Bonnelle T&CG, the photo's show a very interesting machine that can sharpen lathe tools, drills, milling cutters, reamers etc etc. By the way I am in no way connected to the above people. The Bonnelle looks complicated, but not as much as the Quorn, so when I can get some spare time, I will look in the scrap box and harrass my local steel merchant, and see what eventuates, Maybe Harold Halls grinding tool holder could be a start , then the Bonnelle or a variation on all of them. As for sharpening by free hand, I can do it reasonable proficentley, but its a real hassle cause when my fingers get hot I know the tool is probabley way overheated and I need to start again. Which reminds me, that years ago while working on site, 30 miles away from the workshop, and trying to sharpen drills up to 30mm diameter, that we had worn, broken, or chipped, and were doing this on the side of a 9" angle grinder, or the side of the portable steel drop saw, now that was a pain in the butt, Why they chipped, was mainley because the holes that were punched in the beams or brackets were usually undersize, maybe the chap punching the holes in the workshop was useing worn imperial size punches and not the metric equivalent, who knows ??? We should have had more backups or at least a decent grinder.

1723 forum posts | Isn't the Bonnelle a Quorn without castings?? The site you mention also sells other goodies to suit us, Reliable and TRUSTWORTHY too.
