I have seen it on some of the how to's that portions of a saw should be taper ground. Does anyone have any info on how this is done????? Or could you point me in the proper direction?
Hi Fred, Taper grinding is usually done these days on surface grinders. You can do it by hand, and Lui one of the members here has done just that. He has a very nice blog describing some of the details. http://handsaw-maker.blogspot.com.au/2011/05/making-saw-blade-for-new-rip-saw.html Well worth a read for those who might not have seen it. Regards Ray
Tapering the blade Thanks for the info. I was looking for a tutorial on taper grinding it. I understand the concept but what techniques and how the process is done is what I am really after. I have a surface grinder but I am curios as to how they are grinding on it.
Hi Fred, I'm travelling a similar path, I've got a surface grinder but have never ground any saw plate, I guess it's about time to give it a try. Here's japansese Nakaya saw blade grinder. http://www.nakaya-saw.com/en/machine_taper.htm I did find a picture of the surface grinder that flinn garlick use to taper grind their hand saws, but it doesn't really tell me much, other than that it's a very wide wheel? I'll let you know how the grinding goes. Regards Ray PS that picture is from facebook https://www.facebook.com/WorkshopHeaven/photos_stream
Old school grinding was on the BIG grindstones ... with the blank held in a wooden 'sabot' for want of a better word. "Disston uses large stone wheels to taper grind there saws. When the stones became worn down they were used to build bulk heads on the Delaware river." http://positiverake.com/?m=201207 There is a picture from the Hawley Collection http://www.hawleytoolcollection.com/index.php?sheffield-tool=audio-visual It is for knives ... but I'm sure I have seen the same thing happening with saws ... half an idea it was about the Disston works. The japanese are still doing it ... for knives at least ... http://www.youtube.com/watch?v=RKx4ZaRCsKc (1min) http://www.youtube.com/watch?v=aU6u80Hyw5Y (1min) http://www.youtube.com/watch?v=K0BtDfJCNL8 (9min)
and finally I came across the sort of picture I had in my head ... didn't think it was this one exactly ... <shrug> ... http://www.wkfinetools.com/huk/z-UK...leryWorks-1/1844-dayInSheffCutleryWorks-1.asp http://www.britishblades.com/forums/showthread.php?84861-Sheffield-Cutlery-Works-1844
