    8" Koa bowl with an ebony bow tie. First time working with Koa and doing an inlay. Had multiple coats of anchor seal on the blank but still split like crazy. Feedback welcome...

    Jason, I'm not a fan of butterflies, but they work and do keep the wood stable. It's a beautiful piece of wood and you did good on the shape.

    That piece of wood, no matter the species, is my kind of turning stock. The more cracks it has, the better I like it. Overcoming a challenge of what some people would call scrap is satisfying...... Jerry (in Tucson)

    Pretty wood and an interesting shape. I'm a big fan of bow ties, and that one looks great!

    "interesting shape" is that the same as when you are to describe somebody and you say they look nice :ponder::sarcastic:

    Not at all. I don't see a lot of straight sided forms which makes your piece more intriguing to me. Should've chosen a different adjective...

    Now if I said, 'I'll bet it has a great personality'... that would be trouble!:sarcastic:

    Nice little bowl, good job on the bowtie, those things are tricky to get a good fit....

    Great job on that patch. Not the easiest to do. Love the bowl.

    I think the technical aspects of this bowl (the surface, bowtie and finish) are excellent, but the shape leaves me feeling that something's not quite right.

    Under the rim, there's a very short curved section, then it goes more or less straight, then there is another little curved section at the base (though that's hard to judge from the camera angle, it might be an illusion).

    IMO, if you were aiming for a straight-sided bowl, then it really has to be straight, not mostly straight. If you were aiming for a very gentle curve, then there shouldn't be a sudden bend close to the rim -- it looks accidental (as opposed to designed).

    Here are a couple of "outflowing" profiles (sorry I didn't get the inflexion point in the ogee perfect, I'm still having trouble driving SketchUp).

    @duncsuss :thanx2:
    Most of my bowls are free form as I go, without much design thought in mind before I start.
    I know to continue to improve I need the technical and concise feedback you provided such as the shape/form which the others eluded too as well. Thankyou for the great post and clear explanation.

    @jasonb I think nearly all turners started out the same way: having a huge amount of fun just making shavings. Next comes a successful bowl, with a good surface and finish. When this is something that can be achieved more often than not, the question might change to: "Is this pleasing to the eye, and does it make me want to hold it? How can I fine-tune the shape to make it better?"

    I just spent the weekend at a symposium and watched several wonderful turners, one of them being David Ellsworth. He emphasized that he might start out with an idea of what he wants to make, but works in a sequence that allows him to change direction if the wood reveals features that can add beauty to the piece (such as figure, grain, embedded objects). He designs, but doesn't allow the design to overrule an opportunity to do something else.

    One of his tips was to arrange your lathe so you can walk around to the back of it and bend over, so that you can see the piece as if it were standing up. (You can do this from the front as well, but then you have to move the toolrest out of the way.) It's a much more reliable way to see what it looks like than having it lying down on the lathe bed.

    Sorry Jason -- I meant to post links to a couple of great books on this subject, both by Richard Raffan:

    Turned Bowl Design

    The Art of Turned Bowls


    I borrowed both of them from my local public library -- the turning club I belong to also has a good library collection, I don't remember if these books are in it.

    IMO, Raffan does an excellent job of explaining why a particular shape works well. I don't necessarily follow his designs, but I try to look at the pieces using those explanations. Things like "does it draw the eye into the bowl?", "does the sweep of the curve make it look like the bowl is sitting on -- or above -- or under -- the surface of the table?"

    Thanks for the reference, I'll check them out. There's a local turning club out here but I haven't joined due to work/meeting conflict.

    Maybe contact the club and ask if they'll put you on their email list, in case they organize events on different days. Our club, for example, normally meets on a Thursday evening, but in March we did a Saturday event and a couple of members who do not normally get to meetings were able to be there.
