That looks great. I really want to give a try at some bowles / dishes a try what angle do you have the saw set at to get those smooth sides? I looked at that poly draw thing while at a different site and lets just say that I was slightly confused.

here is a quick and dirty table .... all the angles are very close to what is needed as I used rounded measurements to do the math. This gives you a bit of wiggle room for mistakes and unforseen events. Carole Rothman has a book she got published by Fox Chapel Publishing called Wooden Bowls from the scroll saw. It is well worth getting if you have not done so. In the book she walks you thru some easy to master concepts right through some things that are amazing.

 

Ok here is a simple table you can use - Remember the table will be set LEFT side down and you will be cutting clockwise ( rotating toward the down side )

 

wood thickness ring thickness degree to set

 

1/2 inch 1/2 45 degrees

3/4 inch 1/2 34 degrees

1 inch 1/2 27 degrees

 

1/2 inch 3/8 37 degrees

3/4 inch 3/8 27 degrees

1 inch 3/8 21 degrees

 

1/2 inch 1/4 27 degrees

3/4 inch 1/4 19 degrees

1 inch 1/4 14 degrees

 

Hope this helps

I agree 100%! I really like the bowls. I'll go check out the book.

 

I was also confused when I read about (kinda still am, I'll get the book)

Think about this guys. If you start with thicker walls say 3/8 of an inch then when you sand to blend and smooth the rings together then you do not have the worry of sanding thru the side ... I have done this several times... some of the bowls the sides are so thin you can almost see thru them. The absolutely hardest part is dust control when sanding. You will be creating a ton of fine sawdust so please wear a mask. After a while you can get to the point that after the glue dries you can rough shape and blend the bowl in less than an hour most times, of course the fine hand sanding will take a bit longer. Sand and shape the inside 1st then glue the bottom on and then shape the outside. The goal here is to get a uniform wall thickness as well as shape. Your 1st bowl makes a great rainy day project
