The bell section forms the bottom 100mm of the shawm. This will be attached to a foot section about 135mm long, which will slide onto the upper part of the body which has been described in the previous posts.

As it was, this block was still not quite large enough, and I had to glue some more pieces on here and there.
I bored a 25mm hole down the axis, with a brace and bit, using the hollow centre as a guide. It didn't matter whether this was exactly centred but it helped. Then I drilled two sets of holes with an electric drill, one set in a ring at 61mm diameter to depth 25mm and the other set in a ring at 36mm diameter to 50mm depth. Taking the faceplate off the lathe, I chiselled out much of the unwanted wood from the inside of the bell.
Back on the lathe, I did the rough shaping of inside and outside of the bell as seen here.
The original hole I bored to start the turning was not precisely centred.
I drilled through this new centre with a small drill, providing a guide hole for the next step.
I was not game to cut this socket too vigorously in case I made it too large. Reaming it later is a safer bet for a good fit.
