Hollow Form

I recently got a hollowing tool and had a chance to take it for a test drive. It was quite the experience and I can see I’ve just started on yet another steep learning curve. It’s like decorating your living room through the key hole in the front door!

This was my first attempt, it is probably more of an enclosed form than a hollow form. The wood is cedar, which is probably also not the best wood to use as I believe it is inclined to crack when turned thin. When I grabbed the blank from the pile I actually thought it was cherry. That seems to happen often, maybe I just want to turn a lot of cherry.

I was very pleased with the exterior profile. I like the shape and the curves flow nicely. It also feels really good to hold, it fits in my hands well. I was not that pleased with the interior profile. I could feel the walls weren’t a consistent thickness and the curves did not flow at all. However, for the first time using a hollowing tool it was nice not to blow it up. I finished it with a seal coat of shellac, a couple coats of danish oil and then buffed it.

I’ve just finished reading “The Art of Turned Bowls” by Richard Raffan. In it he recommends that you occasionally cut a bowl in half on the band saw. It is easier to see the profile of the turned piece that way and so you can see how you could improve. He said you should do it with some of your good pieces as well, not just your bad pieces.

Well, I figured he knew what he was talking about, so …

That was a leap of faith, but I’m glad I did it. Studying the profile of the half bowl it is easy to see how the walls got to thin at the top transition. Also the walls were to thick at the bottom of the bowl. I wouldn’t have minded them being a bit thicker, to bring some of the weight of the bowl down to the base, but this was to thick. Lastly the bottom of the bowl is not flat, it has a funny bump at the center point. All in all, I think I learned more by sawing the bowl in half and I’m sure I’ll do it again.
