It's time for an update on this project.
After breaking my first attempt I got started with another one and tried to get it caught up to about where I was at with the first. The second attempt was not a complete failure and will end up in my collection eventually. I had a heck of a time getting a good fit on the tenon, and after modifying it several times I ended up with a loose fit on a ridiculously long Delrin tenon.
That just wasn't good enough for me so I decided it was time to move on to attempt #3
The third attempt has been more cooperative with me and I've managed to get it a bit further along in the process. I got this one up to about the point where I was at when I broke the first. I managed to get a good fitting integral tenon on the stem this time. I even ended up with an almost perfect alignment of the chamber and the airway.
So now I'm finally able to work on some rough shaping of the bottom of the bowl and the transition to the shank. Before I do that I like to use some masking tape to protect my smooth surfaces and to give me a guide to keep me from taking too much wood off.
I used a 6" disc sander to knock off all the corners and give some shape to the lower half of the bowl.
And this is where I'm at now. I've got the tape off and the stem attached. Now I can get a better idea of what the shape of the stem needs to be. From here there will be a lot of filing and sanding to refine the shape and prepare it for finishing.
Thanks for looking!
