Penn State grinder guide?

Toller, I'd go with the Oneway or one of the similar designs. The extending arm plus the angle jig setup combine to get your wings and tip angles consistent whether bowl or spindle grinds.

BTW if you will take a new grinder wheel and get everything all setup for just the right grinds, then take a piece of say 1/4" plywood and imagine a COMMA (,). Take the pointed end and place in your extended arm. Take the other end and lay alongside the grinding wheel - trace the outline of the wheel on it. Then cut away the excess. Ends up looking like a half moon comet:)

Result is a template that immediately allows you to either setup another grinder when away from your shop or allows for the wear as the wheel diameter decreases. It also prevents you from being confused between bowl and spindle settings on the extending arm. You're left with marking your Oneway jig or making a couple of jigs. Only real difference at this point is the Oneway is adjustable to try other grinds and the homemades are fixed settings. YMMV

I don't remember what I paid for the Oneway but I'd pay it again. Look into it and also see if you can get a club discount. Klingspor, around here, will do that for club members.

Turning Topics: Sharpening Gouges, by Jerry Glaser, from Woodworker West, Mar./Apr. 1997, pp. 39-42. specifically, see figure 5 in this article "William Noble" wrote in message news:46c4f8c0$0$16375$ snipped-for-privacy@free.teranews.com... > and there was a diagram of the Glaser tool grinding thingie posted on this > NG a few weeks ago - that one is my favorite and very different from the > other designs.

Another option is the Tru-Grind Sharpening System from Craft Supplies USA for roughly the same price as mentioned in the first post.

Something I really need to say...

If the rig in the photo from the PS web site isn't of the Oneway grinding system, then it is of a knockoff. Knockoffs bring lower prices and for that reason may seem to be a good thing for us. On the other hand, the fact that it can be done so easily and the fact that there is a ready market for such knockoffs assures us that innovators and innovations will be fewer and farther between. Those innovators have moved the 'technology' we woodturners are using at a startling pace, considering the long history of woodturning -- the acceleration in the last 20 years or so has been remarkable. Do you want it to continue? You decide that you don't every time you buy a knockoff product.

I have a product on the market (not Stubby lathes which I also sell) which I developed because I thought it was a good idea, nobody else was making it, and I've sold a bunch --

But now I have a pretty strong indication that a large company was planning to knock it off. Patents are not cheap to get and an individual has no hope of coming out ahead against a large company in any sort of a patent suit -- even if they win it always ends up costing them lots of money. And the knockoff companies know that. I have another product ready to go -- part of it is what I think is a much better implementation of what is out there already and part of it is unique. I have another idea after that one -- the prototype is working just fine and it is yet another major improvement on what is available -- you'll like it. This is a little retirement business for me, I don't expect to make a lot of money from it, and don't really care. But, if all I'm doing is making money for the knockoff companies -- f..k it! They could buy people's ideas, usually for an amount which really wouldn't hurt their bottom line a bit. But, that would take the fun out of it for them, I'm guessing.

And, you are helping them do it to more and more innovators every time you buy from them.

I have one "invention". I put it in quotes because it was an existing product; I was just the first to think of selling it as a consumer product; thick brown felt pads. Up to then it was just thin green felt pads. Sold like crazy, eventually getting into virtually every hardware store in the country. Lasted about 12 years until everybody copied it. You know you have done good when 3M imitates you. Yeah I would have liked it to go on another 12 years; but I can't figure out why they didn't do it earlier. The marketing boost it gave us for those 12 years was incredible. It's just a crap shoot. You innovate for the edge the first mover gets; after that it is dog eat dog.

The oneway is 50% more than the PS. If I get it, I might get the Oneway because PS is typically a crappy product and I would rather pay 50% more to avoid problems. I was just torn between a JDS cyclone and a much more expensive Oneida. I went with the Oneida because of their differing reputations. I have had problems with the Oneida, but they ship out replacement parts same day. My understanding is that replacement parts aren't available for JDS (though that is hard to believe)

I remember hearing that popular Arab musicians put out many albums. The average life of selling a new album is only a few weeks. By then copies (by outright theft) have taken over.

I read an article in Fast Company about Adidas. They will be the clothing supplier for the Olympics. They have an Asian IP (intellectual property) head. Their focus is not litigation, but tipping police to retailers with knock-offs. Over 1000 raids resulted last year.

I don't like to see people stealing ideas. If you have a patent or trademark you have a right to resist those stealing your ideas, otherwise you just hope to get good sales during the window when you have something unique.

Looks like a woverine knock off, doesn't it?

I tried Darrell's shop made version and found that I just don't feel comfortable with the tool handle in the socket type grinding..

Ended up with the tru-grind for about $100 and I've been very happy with it... Sharpening has always been my weakness in turning and now I can do edges that I didn't think I was capable of.. My tools last a LOT longer now and have consistent edges.. No more "re-learning a gouge every time it's sharpened.. lol
