OK, this is the latest HF, yes a Work In Progress (WIP).

Notice how deep I went this time round with the captured hollowing rig
About 25 cm ( 10") and I have to say, that the last cuts were fine cuts, or the whole rig would vibrate something awful, still, it worked well.
I've finished it with sanding sealer and two thinned coats of cellulose lacquer.
I'll let it sit for a while and harden, then sand it some and such.
I'm not sure I'm going to put a cap, or collar on this one, but I've not made up my mind yet.
So, how do I turn off the bottom?
I'm thinking to take it out of the chuck, swap ends, and make a jam chuck for it. The one thing I worry about is the bark inclusion is really weak, I fear that if I put any pressure onto the neck, or spout of the HF, it will crack, so, what I was thinking was to put a LONG jam chuck into the HF so the chuck jams against the inside of the bottom of the HF, if that makes sense.
