>Very nice David! This bowl has a nice full form to it and a very good curve. I am glad to hear the compression chuck is working well for you.

Keep up the good work!

>When a person says feedback welcome, I sometimes take it as a challenge, so here goes. I really like the shape and form. The inside curve seems to be of a larger radius than the outside, so I have a suspicion that there may be an increase in thickness in the transition from wall to bottom. This is not necessarily bad, actually it probably is a good thing, as the constant curve on the bottom needs the weight for the piece to sit upright. Great looking bowl...

Thanks David

>Thank you Bill.

Yep the chuck works great, I was really impressed with the idea when I first saw your webpage. I'm pleased I took the time to make one now, as I'm looking forward to fettling the bases more on my turnings now :o)

>Hi David,

Thanks for taking the challenge. Glad you like the form. Your observations about the wall thickness are correct. Since reading the Raffan book I've come round to the idea the wall thickness can be different. Previously I had been obsessed with getting constant thickness.

I think if I did another I would go slightly thinner at the base. Like you say it is quite heavy.. I think maybe just a bit too much. When I've done another slightly thinner I'll be able to decide which I like best.

Thanks again, I really appreciate your feedback.

>Great shape and it looks like you�ve got that uninterrupted curve anchored!

I understand the need for the extra weight in the bottom. Great Job.

>David:

I generally agree with you about not being obsessed about having to have constant wall thickness. Where it could make a significant difference is with turning green wood--the difference in wall thickness could lead to differential shrinkage and cracking--especially on very hard woods .

Thanks George

>Hi David,

Couldn't agree more about the green turning. I've made sure I kept even wall thickness for those. As an experiment a while back I turned a small piece in spindle orientation and put various featues in it as a test. At all the sharp changes in section it cracked or warped badly. Fortunatly all my green bowls so far have just gone a bit out of round in a nice way.. no cracks yet :o)

Cheers

>I like the shape, I think you got a winner here. How well does the bowl rest on the table? The bottom looks round.

Re: Maple Bowl, feedback welcomed

>Thanks Ron,

I just checked how it stands on a hard surface to be sure. It sits on about an inch in the middle. It does rock a bit if you touch it. However, the weight keeps it stable and there is no way it would tip over. On softer surfaces (say with a heavy table cloth it is even stabler and probably touches over 2" or so)

I like how it rocks and the next one will be lighter in the base I think to see how far I can push it.

Thanks again

David
