How 'Bout This

PS

Forget to mention that this is a "down-hill" only  If that's not clear, let me know and I'll try to diagram it.

Re: How 'Bout This

I am learning this cut. For years, I would roll the flutes to 90 degrees and cut with the nose. This gives a slightly higher shear angle for the cut. With this cut, you are still cutting with the nose, but on the up hill side. You have to be careful not to rotate to the 11 o'clock side of the cut. If you come off the wing bevel, you can get a very nasty catch. I mean really nasty!

Re: How 'Bout This

Richard Raffan described that cut in his 1985 book, Turning Wood. It's also been taught by JoHannes Michelson for a several decades for the interior cut in his hats.

Old News?

I didn't think I invented it, but self-discovery is sometimes the best way to learn.

Re: Old News?

I thought you wanted to know if anyone was using that cut. My mistake.

No Mistake, Dick

I should've been more clear in referring to boiz n gurls here on this board.

Re: How 'Bout This

Took a 1-day class with Mike Kehs many years ago. He was teaching a technique he was using to create thin walled vessels to pierce like Bin Pho. So basically, for this class, straight walled vases with about 3-4" openings.

I didn't quite have the skill (and probably still don't) for it. He used the same gouge presentation to go down the inside wall. Biggest problem I had was failing to turn the gouge at precisely the right instance when reaching the bottom. Worked pretty good for the walls, but that bottom turn was tricky.

On another note, Richard Raffan uses a 5/8" spindle or detail gouge to shape the outside. Even though the steel is substantially thicker, they are cheaper (or were, haven't priced of late) than the equivalent bowl gouge and subject to less vibration. I have one and like it. Think it is a Thompson. Also is pretty good when making those Sfirri multi-axis candlesticks. And with a spindle/detail grind, you get a long edge to use for shear scraping should you choose to do so. (Is Thompson still selling gouges? Don't see any ads in the AAW Journal anymore.)

Re: How 'Bout This

It looks like what I think Richard Raffan calls a back cut in one of his Youtube videos.

Re: Old News?

I sometimes use that cut.  It works like a charm when I am successful.

Am I wrong in thinking this is the "hero" cut?  I think I was told by someone that saw me doing that cut that it was the hero cut.

No Clue

Didn't "get" it from anyone, just started using it on the outside of bowls then transferred to jars.� Saves a lot on sanding.

Sanding, as in the 80 grit gouge

two comments

1) I used that cut when I was a novice and didn't know any better.  It worked, when I did it right.  I haven't done it for a long time.  ;-)

2) The result, both in terms of result, and result ;-) depends strongly on the grind -- namely, how steeply the wings are either "sharp" (highly acute) or rolled over.  When poorly/improperly cut, they can be very aggressive, but that works for this cut, when it works.  If they are more properly rolled over to be equal to the nose angle, it's a lot safer, but perhaps somewhat less effective.  

Re: Old News?

I’ve never reached the limit using the JoHannes grind. I keep thinking I’ve rolled too far, but I’ve never had a catch. 

I first heard the term"hero cut" from Don Derry many........

...years ago. It is a bevel "gliding"finish cut from rim to bottom without any bouncing or interruption, ready to sand with 320 grit!

Indeed! All or nothing!
