PN Detail Gouge
Stuart Johnson
>What is the proper way to use the PN detail gouge with the secondary bevel? I didn't actually sharpen it in the photo but just touched it up lightly so it would appear in the photo. It cuts very nice but is going to take some practice. I also don't see how to sharpen it with the Tormek.

I call the area you are pointing to the main bevel and that long thing on the bottom the secondary bevel. That's probably just me. All you are worried about sharpening is that short bevel your arrow points to. I do that either by hand or with the Wolverine jig depending on which spindle gouge I have.
That second long bevel is just to get rid of metal to make it thinner so you can reach into details better, such as inbetween two beads. My secondary bevel isn't ground quite that long. I grind away enough metal to give me clearance. Then each time I go to the grinder to sharpen I hit that long bevel by hand just to keep it ground away.

>Thanks John, the long bevel being the secondary makes sense and takes care of the sharpening problem I thought I had.

>As suggested in another posted response. The long bevel is just to remove metal and allow the tool to get in tight spot better. Grind the Detail gouge with a finger nail grind like a spindle gouge. I use a 40 degree bevel. The advantage of this tool is that it reduces vibration typically associated with a spindle gouge.

>HI Stuart, Here's what I do.....put that gouge in a wolverine jig designed for sharpening the Ellsworth grind, and sharpen it the same way....the wings swept way back. I use no secondary bevel at all, no need.
The tool will have an amazing transformation! If you haven't ground that way before, find a club member for some help, or check the grind library here at WC for ideas.
So you are the Jensen Grind guy.

>I asked in a post last week what a "Jensen Grind" was. No body answered my question. But it was buried in a thread and most people know not to take me serious anyway.
Is the grind used on regular bowl gouges?
Are these grinds used on spindle gouges too?
You can probably tell I am not a spindle turner. I am hardly a turner at all.

>Yes, I am that Jensen. Woodcraft wanted a pre-ground bowl gouge to sell. They chose to put my name on it. The grind is a typical Irish or Swept Back grind for bowl gouges. I use three grinds when turning bowls. This typical Swept back grind for roughing, a 40 degree bevel grind using the Stuart Batty grinding method and a 40 degree bevel ground strait across ground (english sytle) to finish the last 1/2 of the inside of the bowl. May seem like over kill to use three gouges but I can get a tear out free cut when I do this.

>Greg,
Strongly suggest you add your grinds to the "library" you'll find at the end of the link in the upper left corner of this frame. A picture of each, especially with a bit of accompanying text, is vastly helpful.
