Greetings all,

Recently I've been tweaking the grinds on my bowl gouges and was wondering:

What are the advantages/disadvantages of "V" shaped flutes, and "U" shaped flutes. Is there a grind thats better suited for each one to facilitate its use?

Devon,

As I understand it, the "v" makes for a bit more rigid tool because it leaves more steel in the side walls. The "u" does a better job of clearing shavings when cutting with the wings because the "v" point will tend to clog as shavings "pile up" at the bottom of the flute. I have a Glaser b/a 3/4" gouge ("v") and several Ellsworth 1/2" gouges ("u"). I actually use David's grind on the Glaser. They each work well, although the Glaser is heavy for doing any kind of detail work.

Interesting. My experience has been different. I prefer the open V shape because it blows the shavings out a lot easier. I have turned with some U shaped bowl gouges and they always clogged up on me. Like Mark I have a Glaser gouge as well as more conventional gouges, and I agree that it is not really suited for fine work. But if I want to be knee deep in shavings within minutes, I grab the Glaser and crank up the Poolewood! It does a great job on reducing a rough blank to round in very short order.

I like the U because the shavings curl and eject, even when hogging heavily. The V sometimes folds 'em and creates a jam. I cut with the handle close to parallel to the rest, though. If you are a bigtime handle-dropper, probably doesn't make a lot of difference.
