I have been working on getting a few long standing projects finished, and these are two of them.

The first is maple, the blank started as 9” in diameter and 6” deep. The finished form is 8” by 5”. The hole was 3/4” until the very end when I had a catch at the bottom. To take the “ding” out where the tool hit the edge of the opening I had to widen it to 1”. It was finished with wax and buffed.

The second is ambrosia maple which started out 6” in diameter and 4” deep. The finished form is 5 1/2” by 3 1/2” with a 1 1/4” hole. It was finished with poly.

Thoughts and comments are always appreciated as it helps me in my learning process.

Thanks. I probably also should have added information about the wall thickness. They are 3/8” thick.

Nice work! I’m a nervous wreck when I do something like that, just knowing something awful is coming.

Really nice work! Would you post what kind of tools you used to do the hollowing? I would love to try this kind of hollow form, but I can’t even imagine how you worked through those tiny openings.

Thanks all, they are definitely fun, and can be a challenge at times. The biggest challenge I have had with holes this size is not “hooking” the tool on the inside as I remove it from the piece. There are times I have even stopped the lathe before taking it out as I was not 100% certain where the cutter was in relation to how I was removing it.

RoodyJ, they are just standard swan neck hollowing tools. Nothing fancy, or any of the new “specialty tools” that are available. I am headed to the shop now and will snap a picture to post later.

RoodyJ, below are the tools I use for hollowing. I primarily use the yellow one (from Gladstone Tools) as it has a longer handle than the Sorby, and is easier to control. Which shaft I use depends on what I am doing. If I recall I used the smaller one (currently attached) for the maple form, and the larger one for the ambrosia maple form.

I also have a set of micro hollowing tools from Gladstone, but I only use those for ornaments, although I have been known to use the Sorby on those if they are too large for the micro tools.
