Let me see your Irish Grinds on your bowl gouges....:D

I'm trying to figure out if I built my jig correctly and if I ground the profile right...

I was making a nice goblet, and I had a MAJOR highsidet.... :eek::D

The goblet was down to about 3/8", and I was getting real nervous, sure enough, one wrong "thought" and poof.... toothpicks!

I'm also figuring out that my lathe is too low, I'm going to move it up a few inches.

Show me them Irish Grinds guys!

Cheers!

Stu....I had one go poof yesterday. I had finished the cup section, a small detail just below the cup and about 1/4" of sized stem below the detail. I had sized the foot and was using my spindle gouge to remove the bulk of the excess on the rest of the stem. I'm nearly deaf so I can't hear the subtle sounds other might. I first noticed a rotating black area. Then the launch. It turned out that either a rotted knot or a insect larva pocket about 5/8" x 3/4" laying in the exact center running with the grain in the center of the stem area. I've been working with some wet cherry and I've not had vibration issues. I do keep my tools sharp though. Doesn't take much....just a quick pass. Good luck! I like your first entry.

Thanks Ken.

My grinder is about 2' from my lathe, so I sharpen often.

I have a few chunks of wet wood here that I might gind time to do tomorrow, but, I also sold one of my motorbikes, and I have to get it ready for the new owner to come and get next week, so I'll be spinnig wrenches, not wood.....

Cheers!

Stu, if you have broadband go to Oneway's site and check out their video of the wolverine doing side grinds. That should give you a good look at side grinding and some thoughts about building a jig.

[Jim Becker]

Look at example E near the bottom of this page: http://www.peterchild.co.uk/info1/sflute.htm This is a little more extreme than the Ellsworth, but does illustrate what a side-grind looks like on a bowl gouge. Also, not every gouge will grind this way well...flute profile will greatly affect it, especially at the tip.

[Stu Ablett in Tokyo Japan]

Thanks Cecil, I'll take a look.

I guess I'm griding mine like example E....

[Lee DeRaud]

Look at example B near the bottom of this page: http://www.peterchild.co.uk/info1/sflute.htm This is a little more extreme than the Ellsworth, but does illustrate what a side-grind looks like on a bowl gouge.Is that a typo? The Ellsworth I saw at Woodcraft looked more like example E.

Yea...fat-fingered it. 'Doing three things at once as normal... Thanks. I corrected the original post.

[Stu Ablett in Tokyo Japan]

Good, that means I've got it somewhat correct!! :D

[Stu Ablett in Tokyo Japan]

OK, some pics of my jig, and the grind...

Well, what do you think, could you work with that?

Stu,

If I didn't know better I'd think you were McGiver! All you need is a Swiss Army knife.

Ya, I get that all the time, wish I was as good looking, or as thin :rolleyes:

I met him while he was filming at UBC (Vancouver Canada eh) Ice rink for one episode, VERY nice guy!

Oh yeah, I have a Swiss Army knife, it even has a cigar cutter! :D

Cheers

I don't have a bowl gouge. Can I show you something else?;)

:D :D :D :D

Hi Stu

It is hard to see in the picture, but it looks like the edges of your grind may be very sharp, as in knife edged. If that is so, you may find the tool extremely grabby. Mine is sharpened in such a way as to have the bevel rolled over a bit, making the angle between the outside beveled edge and the inside flute larger. It is still sharp and cuts very well, but it doesn't grab like a knife edged grind will. I will get a picture and post it in a bit.

Also, that is one of the longest bevels I have ever seen! I thought mine was long, but you have me beat. Nothing necessarily wrong with that, but it may contribute to that knife edge thing.

Hey again Stu

I just got down from the shop with a couple of pictures. They are a little fuzzy, but hey, I am a little fuzzy right about now too. But, they should illustrate what I am talking about, at least I hope.

Here is a shot of the side of my grind. It is fairly long compared to some famous turners, but I like it, and it cuts well for me.

Here is a shot on end. Hopefully you will be able to see what I mean by having the edge "rolled over" a bit to keep it from being knife edged. If not, let me know and I will try to clarify it a bit.

Bill

[Stu Ablett in Tokyo Japan]

Hey Bill, you da man!

That is what I was looking for, you are correct, I have a knife edge on mine, and it is grabby, I just thought I sucked! :D

Well, now I have to figure out how to fix that! :D

Thanks a lot!

Cheers!

:D :D :D :D

As long as it is tool related and "G" rated, sure thing! :D

[Stu Ablett in Tokyo Japan]

Setting here thinking about this, I have a gouge, I do not think it is a bowl gouge, as the distance between the two sides of the gouge is large, I'd say it is a roughing gouge?

Here is a pic of Bill's Bowl gouge...

and a lousy pic of mine...

(I'll get a better pic)

I think you can see that mine is a lot wider, so, am I wasting my time trying to get this long grind on it?

If I am, which one of these gouges should I order, the 1/4" seems small, so I guess it would be between the 3/8" or the 1/2" bowl gouges.

I've got an order in with Grizzly, and some items are back ordered, so I was hoping to order a gouge or two and have them added to the back ordered stuff.

Got to have the right tool.

Cheers!

[Stu Ablett in Tokyo Japan]

Hey Bill, your pics are great, I took a good dozen, and I have to say, it is hard to take a pic of the edge of that gouge!

Note a nice tight flute like the bowl gouge you have.

Cheers!

[John Shuk]

That looks like a spindle gouge to me.

That looks like a spindle gouge to me.

Ya, that is what I thought...:(

[Jeff Farris]

Stu, that is a spindle gouge, not a bowl gouge. The flute on a spindle gouge will be a broad "U" shape, while a bowl gouge will more of a "V". A true bowl gouge will take a nicer "wing" than a spindle gouge with a short main bevel angle. In my opinion, you have that side ground way, way, way too far back. My suggestion to my customers is to never grind a bevel longer than you intend to use. If I have a gouge ground back 5/8", that means I plan to use it to take 5/8"wide shavings -- at least some of the time. I see a lot of guys pull the grind way back, and then use the front 1/4" and wonder why the tool has a tendency to grab.

Now, take the tool you have in the picture and grind the primary bevel angle to about 35 degrees and shorten those sides down to about 1/2 an inch, and you will have a lovely detail gouge for working on the outside of your work, just don't try to go inside with it.

[Stu Ablett in Tokyo Japan]

Thanks Jeff, I'll give that a try.

Looking for recommendations for a bowl gouge.

Cheers!
