Traditional grind gouge cutting inside a bowl

Further demonstrations with the traditional grind gouge. This segment is spliced together from several different turning sessions so there is some repetition and there are about 3 different bowls being worked on.

Hi Bob, and hi from here in the UK,

Your videos are the most instructional I have seen and a great help in learning from the master.

I have a real problem with catching, mainly when hollowing a bowl. It mostly goes OK until I get to the smoothing cuts, especially in the corner. It seems that no matter what tool I use (bowl gouge, spindle or scraper) it will catch just as I touch the wood even though I use a very light pressure. Any help would be appreciated.

@alandurant1: Hi: It is hard to say what would be causing that. It is highly likely that you are not maintaining bevel contact as you make the transition from the wall to the bottom of the bowl. If the transition is quite abrupt it is almost impossible to maintain the bevel contact unless you have a gouge with a very steep bevel grind and the heel relieved so the bevel is very short. That keeps the edge support very close to the cutting action.

With a scraper the bevel support is not the issue since the bevel is not rubbing when making a scraping cut. Catches with a scraper usually are the result of letting too much of the edge engage the wood. If you are using a round nose scraper it is very easy to inadvertently allow more of the edge to start cutting as you enter the transition area. Try turning a few open form bowls where the curve is continuous and almost spherical, eliminating the abrupt transition to see if that helps.

:)

Can anyone explain how to grind a "traditional grind gouge" I'm using tormek t7 methood and I have my bowl gouge setup to 50 degree bevel if I'm not misstaken

keep up the good work Bob and regards from Sweden..

Hi, and thanks:

In the preceding video, titled "Gouge cuts", I explain the method for grinding a traditional grind gouge.  I believe the bevel angle on mine is between 45 and 50 degrees.

Take care

Bob

Thanks Bob,

All my gouges (bought as a starter pack with my system) have a very shallow grind and don't look like the 'traditional' grind you often mention. Perhaps I should re-grind one of them as you suggest it should be? Otherwise I will keep my eyes open for one.

Regards,

Alan

Bob, I believe awhile back you described the box you have your video camera in. Can you send me an e-mail about this?
