Sharpening metal lathe bits
Sharpening metal lathe bits
Anyone have any advice? I currently have been sharpening my bits with stones rather than on my grinder(the grinder scares me for the wee bits my Taig uses) and I'm still not sure I'm doing it properly. From time to time I get a bit of gouging of the stock which can cause considerable problems if it gouges too deep. This happens on a simple pass across the material I'm turning and I'm careful to not be aggressive when I'm turning. I seem to recall waaaaaay back when reading about "breaking the point" on these kinds of cutting tools but I'm not sure if that's the issue. Any thoughts?
Some issues of South Bend's "How to Run a Lathe" have good info on cutting tool geometry. Here's a file from the Yahoo SB group that specifically refers to Taig bits, maybe there's something you can use.

Hmm, it worked once, now doesn't. I went to the Yahoo SB site:

Which is where the article was found, "Stantoogrinding.txt"

Well Jack, you did it again. Sent me off on a bloody internet snipe hunt. Well, this time I actually managed to bag a snipe!
Since I stink at grinding tool bits, I decided to check out a couple of how-to's on the subject. Hot on the trail of a snipe, I followed various links around the internet getting further and further from the original subject. I eventually cornered the little bugger at this site: http://www.radialarmsawrecall.com/
To my joy, I realized that I probably qualify for a free new blade guard, since I have that exact saw! I'll know tonight when I get home from tending THE BOSS's mind numbingly boring store and check my model number.
Hopefully I can expect a snipe in the mail, trussed and stuffed, ready to mount. (I mean, mount on the saw, not me mount it, you rude buggers). The irony is, my current blade guard is jerry rigged holding it in place, but I was damned if I was going to pay $50+ for a new one.

I just got this:

It's a great little sharpener. The wheel turns at very low rpms, and there's a water reservoir under the wheel to keep it cool and lubed.
It won't turn your tools blue. The bits are cool to the touch immediately after sharpening.
