I sharpen the TC tipped CS blades at the local men's shed using one of these...
370W Circular Saw Blade Sharpener | Sharpener Forestwest
I purchased a second diamond grinding wheel for it off eBay or AliExpress and it works perfectly fine. Can't remember exactly what I paid for it, but definitely less than from Forest West.
While on the topic, does anyone else use one of those styles of blade grinders? It is an excellent unit other than the indexing stop arrangement. Has anyone made an adaption that works any better?
I recently bought one from Forestwest and I was really disappointed with it's design. Not all of the unit just the indexing and blade holding setup.
I found that the indexing was almost totally useless and imposible to adjust. The knob that clamps the blade would unscrew as you turned the blade to the next tooth.
I made a new spring loaded clamping arrangment that replaces the original pressed metal washer. Now once you tighten it, it holds the blade securely but still enables you to index to the next tooth securely. I then found that, after you set the angles correctly, the indexing pin was not required as you just learn to feel how much you are removing and it does a very good job.
So far I have sharpened about half a doz blades and I am very happy with the results.
My advice is you get what you pay for.
Thanks, Bohdan.Quote:

I'm interested in the clamping arrangement you devised for holding down the blades. Any chance of a photo?
Because I am re-sharpening the same blades at the Shed up to a dozen times before replacing them (they sure knock them around), if I just go by look and feel when I regrind then some teeth will end up being higher than others and doing all the work. So, I'm trying to find a better indexing mechanism to avoid that.
I have made one change to the indexing mechanism that has only slightly improved it. I'm hoping that someone out there might have come up with a much better design that I can adopt...:rolleyes:
