Cut away form for hollowing

[Jim Silva]

Hey all,
I saw a turning dvd in the not so distant past that had the turner cutting away part of a vessel he was hollowing to allow the camera to see what the tool was doing inside where it wouldn't normally be viewable. We're doing a hollowing demo/discussion at our local club and I was wondering if we could use that approach in the demo. However, my trusty brain has let me down yet again and I'm unable to remember who it was or how much of the vessel was cut away to allow for viewing WHILE turning. I'm not talking about something cut in half after the fact to show wall profiles.


I know that Tim Yoder did something to that effect a while ago but it's not he I'm thinking of. Does anyone know the video in question? Or have a link to the video Tim did? How about a photo of said cutaway that may eliminate some rather disastrous experimentation on my part while I try to figure out what I can get away with?



Thanx in advance
Jim

Jim,

Mike Mahoney and Richard Raffan, both have videos using that technique for teaching hollowing.

I think David Ellsworth has something like that in one of his videos.

David said today, use your hollowing tools on a bowl for practice, see what you are doing and see what happens when you turn your tool different ways

Jim This may not be it but I did the cutaway vessel thing when demonstrating the Hunter tools.

John,
That's what I was looking for. Not the one I remembered but just fine. I was trying to remember how the vessel was cut away to allow the camera to "see through" to the inside. Now I've got something to work with. I think your version is better than the one I saw with only 1/3rd of the piece cut away if I remember correctly.

Any other cut away design ideas would be welcome but this gets me on the right track.

Thanx again

Jim

Jim,
I didn't look at the videos posted, but a technique that I've seen often used was to drill fairly large holes in the wood at least an inch deep. Make sure you drill in a "checkerboard" pattern -- not all in rows, but alternated. With the speed of the lathe, the audience (and camera), will be able to see the motion of the tool.

(Alternatively... you could go through the side of the hollow form! That brings some cheers from the audience... and a better view!)
