Crown PM Bowl Gouges

Barry N. Turner

>I was in Woodcraft today with an eye for a new bowl gouge. I looked at a couple of Crown PM's. One had the Ellsworth grind, the other a straight across grind. The sales person told me that the straight grind is much better for the inside bottoms of bowls.

He also told me the flute of this tool was more open, similar to a super flute. The Ellsworth grind gouge has more of a V-shape flute. Really there was very little apparent difference in the flutes. Except for the grinds and the slight difference in flute cross sections, the gouges were identical.

Oops, one big difference, the Ellsworth grind was a full $20 higher in price! I didn't ask if David Ellsworth ground it personally, but I couldn't believe the difference in price. Is it worth it? How about the flute profiles? Any noticeable diffeerence in performance?

The clerk suggested that I buy the cheaper and use my Vari-grind jig to convert it to an Ellsworth grind. Comments would be appreciated. Thanks.

>That is what I did was buy the Crown PM bowl gouge with the traditional grind and put the swept wing grind on myself and I love this tool. I got mine at Klingspor's a lot cheaper then the other place.

>I bought a PM before there was an Ellsworth grind, and used it with a swept back grind that I did freehand (some kind of wavy multifaceted work there), then when I took a two day class with Lyle Jaimeson he put an Ellsworth grind on it. It works great. I used it very little with the traditional straight grind before I altered it so I can't compare. All in all it is a very good gouge with good edge retention and edge sharpness. Save the money and gring your own Ellsworth on it. MP Wall

>I much prefer the U shape flute(like Sorby) over the V flute because it is easier to sharpen with side grind similar to Ellsworth but not so long on the sides. A V shaped flute doesn't have as much cutting surface exposed because it is too pointed on the tip.

>I only have one bowl gouge, a Sorby 3/8" with a side grind. So, I don't have a lot of experience on the subject. I'm just looking to branch out a bit.

>I have a Crown 3/8 gouge that I ground back with the Ellsworth jig and a P&N 1/2 gouge that I ground back . Both are excellent tools. The P&N came unhandled for $27 from Crafts Supply. I think they're even cheaper from Lee Valley. I made a nice handle out of some pecan I had laying around.

The Crown Ellsworth signature gouge is nice but I don't know that it's $60 nicer than what I already own.

I have no affiliation with any of the businesses I mentioned.

>Strange I just purchased another "Ellsworth" ground gouge from David. It has a definite "U" shape not "V". The Taylor made gouges with the so called "Ellsworth" grind use a template made by David to get his 63 dergee face and sweep.

>I started using this grind recently and like it very much. You can do so many things with it. I'd recommend watching David's video on the tool or Bill Grumbines video, which I think is one of the best I have seen. Good luck.

>I'm with Darrell here... I was confused by Barry's description of the Ellsworth gouge as "V"-shaped, as I consider it rather round-bottomed, and more like the Sorby, especially if compared to something like a Glaser bowl gouge, which has a very small radius flute.

In these descriptions, we should keep in mind that the Ellsworth signature gouge is not just a particular grind, but a particular grind geometry on a gouge with a particular flute shape. Some people get all flustered about different grinds being called "Ellsworth" or "Irish" (or "Celtic") or "O'Donnell" or "O'Neal", and yet each IS slightly different. Not all 'swept back' side grinds are the same, because the bevel angle and the flute geometry are both important to the performance, and can be slightly different between these different gouges. SO, you can put a swept-back grind on any bowl gouge, but unless the flute geometry is ths same, it won't be exactly the same as the real Ellsworth.

Many turning books recommend using a bowl gouge with a relatively short straight-across bevel to work the bottom of bowls, which does, indeed, work well. One of the benefits of the Ellsworth gouge is that you have that shorter (steeper) bevel built in, near the radius of the flute at the tip, and the bevel length and angle change as you move away from the tip, and up onto the wings.

Safe spinning,

>Barry, I compared the two gouges you refer to at Woodcraft, and had the same question. I took a piece of soft pine from their workroom, and pressed the gouges into the pine, to compare the flute geometry. To me, it was the same gouge, but the signature gouge's handle was much larger, in comparison. So was the price, as you have noticed. I bought the signature gouge for a comparison a group of turners asked me to do, but soon sold it to a student. I'll stick to my Glasers. I find their shape more than adequate to the tasks I put them to.

>Well, the cross-section looked a bit v-shaped to me. More so than the same gouge with the straight across grind.
