Another elm wing bowl in the works

I think it was Al who told me that I should try skipping the mortise.
Well I'm having a go at it with this one. Still have to turn the thing around and turn the other side.
Haven't quite got my head around how I'll do that, but Se La Vie

I may try vacuum chucking it. I had a really nice commercial grade rotating union from Deublin tossed in my lap and I'm almost ready to assemble a vacuum system. Maybe it'll wait for that.
 
Raul, I would have left a hefty tenon on the bottom, turned the inside and tops of the wings, and remounted to turn off the tenon. I would hesitate to hollow a winged bowl using a vacuum chuck. I would be concerned that tool pressure would cause the bowl to creep, causing a wing to hit the tool rest or you. Turning the top of the wings might be even more dangerous. I can envision a plywood fixture on a face plate into which the bowl could be mounted and positively secured.
 
I should add that you can reduce the risk by using the tailstock center while turning the wings and during part of the roughing out of the bowl interior.
 
thanks for the suggestions. I considered hot gluing a tenon to it. As you can see I won't do that. (edit) or maybe I shall I'd only need to turn past the BLO to get to fresh wood and that doesn't go deep.

I am will use the tail-stock and am considering a shaped butt plate, mounted to a faceplate, to turn the wing keeping it captive. From there, I have various notions about stock removal in the bowl. After turning the wing I'll have to address the post inside the bowl and I have a sneaking suspicion that there won't be any speed above 12 rpm. I do have a plan, a lunatic one, but it's a plan.
 
I have often used CA to join wet bowls to a drywood glue blocks
( learned it from Lyle about 15 years ago)
Works great for wood that will only be on the glue block less than hour.
The glue block is taken off by fracturing the glue with a chisel.
CA is about the only glue around that is not stronger than the wood.

If the wood is moving at all the wood movement will fracture the glue joint in a few hours.
