Grinding/Sharpening Help?

Newbie

>Gents, as you know I just started turning. Well, tonight, I just started sharpening and I am all screwed up. Let me split this into two categories.

Category "A": The two gauges. One Glazer with that swept back, choked down grind. The other a Henry Taylor with the more open grind. I THINK (emphasis on ignorance) that using the wolverine jig I'm getting good profile. Aka, a hollow grind and no "facets". I'm using the 60gr Alox (grey), and the white alox wheel that came with the grinder. Now, both tools came obviously honed (bright and shiny for a mm on edge and heel). I can't for the life of me get that hone back. I just spent an hour with a little translucent arky slip going "scrubba scrubba". No love. So first question: how to get that edge truly honed? I tried, by the way, turning as is. The edge I get off the grinder is far inferior to the honed edge--and get useless much more quickly.

Category "B": The fat butt glazer roughing gouge. This is a fingernail grind, but is WAY too fat to fit in the wolverine jig. A desperate, frustrating half hour on the grinder, and the original grind is all screwed up. And, I managed to get a belly in it. Anyone care to school me on grinding this thing free hand?

Grinder questions: I have the wheel recommended by Jerry Glaser (5sg46). I can't mount it because the hole in the middle is too big. I knew this, so I got bushings. The bushings don't quite fit, so evidently I need new bushings. But bushings seem only to be sold in 1" widths, meaning the clamp plates won't clamp. Anywhere to find a good selection of bushings?

Also, as regards truing the face, I bougth one of those diamond impregnated block on a stick things. It knocked the eccentricty out of the wheel alright, but left some pretty deep tracks in the wheels. Problem or not?

Lastly, I hooked a muslin wheel to the grinder to try to do with the wheel what i couldn't do with the stones. All I did was end up putting a rounded edge on the back side making the unhoned blade just plain dull. What's the right way to use these "strops"?

However, here is a link to some folks that may be able to help with the bushings:

I would check out the AAW video on sharpening. Several different turners give different techniques for sharpening and it's excellent. John Jordan's section on grinding a swept back grind by hand is truely excellent.

>to the nearest woodturner that can offer help with your sharpening woes. I've been there and I know your frustrations; a little experienced help will show you what you're doing wrong. Jigs, and I use them, are an aid, you still need to know how to achieve the desired profile. I'm a liitle confused as to what gouge won't fit the Wloverine holder, if it's a roughing gouge you don't need the holder to grind it. Just set your rest so the bevel will be sharpened at 45 degree angle and rotate the gouge from side to side. Stop once in a while and make sure you are getting a straight across grind; it's important that the bevel is even all the way around. No high or low spots.

As others have suggested, post where you are, woodturners are giving folk and someone will get with you and help.

>Join a woodturning club and get some hands on help for sharpening. It is one of those things that you can learn in 10 minutes but would take a book to explain.

BTW Oneway sells a larger vairgrind jig for larger gouges. My 1" Glaser is a simple grind that I usualy do by hand. I like the glaser shallow gouge but I tend to use other tools for my roughing gouge (non-Glaser tools).

You have a lathe so you can MAKE any sized bushing you want out of wood (even brass, aluminum or plastic if you like).

Good Luck

Roughing gouge

Jeff Gerardot, Indianapolis IN

>If you're just using the roughing gouge for roughing, skip the fingernail profile. This is what Richard Allen was hinting at in his post -- just do a straight across grind, which only has a bevel to it, no sweep.

Good luck.

>Loose, I did as you suggested and took the tool back to the guy who sold it to me. He got me schooled in about five minutes.

His method, though counterintuitive was pretty obvious.
