Yup, to some degree or another. The avatar be Stitch from the disney movie 'Lilo and Stitch'. He's an indestructible space alien...I guess. Looks more like a koala than a donkey...don't you think?

The only way to get as good a fit with a cylindrical ferrule as can be had with a conical one is to heat it up and allow it to shrink down in place. That is too risky, especially with a thin wall of ebony, which is notorious for being sensitive to heat.
Couldn't you make a form or a mandrel to heat-shrink tubing on?

What good would it do on a mandrel?

And then...? And then...?

I'm not sure, but wouldn't there be a problem removing the heat-shrunk ferrule from a metal mandrel once it had cooled? I suspect this is why it is cold-rolled instead.

To protect and support the mandrel, of course! :roll:

Mr. Quinn, do you have a ball-park figure/idea what percentage of contemporary pipe makers use hand rolled tubing as opposed to pre-rolled tubing. I realize to nail down an exact percentage is a tricky thing, but in you experience, what would you say?

I really can't answer this. I am only sure about the few makers that have already been mentioned in this string.

My guess is only a handful. Some pipemakers learn to do it since they all seem to attempt vintage repairs at some point but, when it comes to normal production, tubing is usually the way.
