A question for the pros:
Is there a method that one can use to expand the large end of a bottom bow to accept a slightly larger bell tail and ferrule?
The difference in diameters is about an eighth to three sixteenths of an inch, maybe too much?

Re: Expanding bottom bow joint
That's an intriguing idea, KT, but I don't have the facilities to make a ferrule that size.
It would be really cool if there were some sort of "data bank" of the measurements of different available bells - maybe there's one already in production that would "fill the bill" of what I'm looking for........?

Re: Expanding bottom bow joint
I have one of those small open-ended rolling mills. I think I could cut a long ferrule from an old bell stem that's rather thick and expand one end by thinning the material on that end. I've made ferrules larger this way but not attempted to make just one end bigger. I'll fiddle with it when I get some of the current stuff off my bench.

Re: Expanding bottom bow joint
It isn't that hard! Visualise things a bit. Something needs to be smaller and the other needs to be bigger.
Required tools - a torch and something like a Dremel.
I won't go too far now as I have been thinking and drinking but will give more detail here or by PM or email if you want more info.
