All 4 of these bowls were made from the same pattern. The differences were the thickness of the wood and the size of the pattern.
The first bowl ( top left )
This Bowl was cut from 1/2 inch thick BB. Sealed with Tung Oil and then top coated with satin lacquer. The pattern was full size.
The second bowl ( top right )
This bowl was cut from this blank that is 5/8 in. thick. The pattern was full size. Sealed with tung oil and then top coated with satin lacquer.
The third bowl ( bottom left )
This bowl was cut from 1/4 in. 3 pile ply. The pattern was full size. I did not use all of the rings. Sealed with tung oil and top coated with satin lacquer.
The fourth bowl ( bottom right )
This bowl was cut from 1/4" bb however the pattern was only 5 inches in diameter. Sealed with tung oil and top coated with satin lacquer.
The two on the top were full size but had different wood thickness. The striped one was 5/8 in and the other 1/2 inch.
The other two were 1/4 inch but of different size ( diameter ) patterns. All the bowls were sealed with tung oil and then top coated with satin lacquer. As you can see there can be a wide variance in making a bowl with a pattern.
