« Part 5: Project 5 - A ring box for Valentine's Part 6 of 50 for 50 - turning 50 as I turn 50 series Part 7: 99% assembly, 1% turning »

I wanted to more fully explore the diameter capacity of the Nova lathe and use the outboard turning setup for the first time. I also didn’t want to slog through a million segments, so stayed with 12 segment rings. To keep a flatter shape, I used 1/2” thick segments for the two largest rings. Glue up was a bit of a challenge, as my bowl press was built for the 12” swing of the Rikon. I found that I had some gaps between rings using this clamping approach, so will need to add a panel or something to spread the clamping force next time. Sanding dust and CA helped fill the gaps.

I really struggled with catches and chatter with carbide tools on the back side of the rim area, and thought I was going to lose the last two rings. I have a Hunter #4 tool that I have struggled with in the past. Taking a class that taught using a steel bowl gouge opened my eyes to the Hunter tool being presented to the work at different angles, not like the square shank EWT and Harrison tools I usually use. Using the shear cutting of the Hunter made all the difference on that chattery rim, and I was able to save the bowl.

18” finished diameter and a bit over 4” tall. Cherry, Shellawax finish.
