Flute Profiles of Bowl Gouges

Peter Toch
Here is another one of those questions if asked of three turners you will get at least five different answers...based mostly on conjecture rather than facts. Let's give it a go anyhow.

The three most popular flute profiles for bowl gouges that are talked about are: 1) "V" shaped, 2) "U" shaped, and 3) "Parabolic" shaped. My question is as follows, what are the performance characteristics of each shape and under what conditions and situations, and more importantly why? What are the "pros" and "cons" of each shape? Yes, I understand there are other shapes also available, so if anyone has any information on them, please let's hear from you too.

Thanks Peter Toch
