I keep reading about long flowing continuous curves make the best turned shapes so I have concentrated on this in developing shapes of bowls and vessels. Regardless of how a piece feels when mounted on the lathe things looks different when finished in your hand or on the shelf. So I have been trying to develop tests for flats and bumps. I have come up with two methods to inspect for small shape irregularities.
1) on convex surfaces I take a plastic membership card (credit card) and 'roll' it up the hill. You can feel and find the tiny-est flat spot.
2) roll a marble or ball bearing under your hand accross the surface to feel for bumps. I think it amplifys them so you can find them. This method is not a good as the card on the outside but I have myself talked into that it works on the inside of a bowl.
