This is Carob, square edge & off center. Within 1 mm of exactly 4" tall x 4" square. The wall thickness is 3/32" for both the bowl and the wings. Sanded to 400 and finished with walnut oil. I still have some sanding to do on the wings, but the bowl is complete.
I found that one of the most important parts is to get the diameter nearest the wings consistent on both sides before proceeding to the rest of the form. Like most other turnings, a slight gradual curve was more pleasing to the eye than having a straight side (I tried straight first). I also learned what everyone has told me about doing these...keep your fingers clear, those wings sure hurt when they hit your thumb!
I received Chris's piece today and I'm very impressed. Besides a unique and interesting design, the quality and skill are something for me to shoot for. If you've never seen something turned 3/32" thick, it's about like a potato chip and this piece is finished as smooth as glass. Thanks Chris
