Found your bowls built by using the scroll saw interesting, I have never done anything like that. It jogged my memory of the process I seen in a book using a bandsaw. I| take it you just got a ringmaster and are using it now.
All projects are nicely done.
I was using the scroll saw to make bowls. I bought a Ring Master and I use that to cut, sand and apply the finish. It only makes round projects however. I will still use the scroll saw for oval bowls. I got a book by Carol B???? On making bowls on the scroll saw. The RM makes a more accurate bowl and applying the finish using their products does a great job.
