What I did was glue in the tube, leaving enough hanging out to build the CB onto. I tried to square the end for the CB with a parting tool, but it was never right. I ended up using the skew to get a good cut. I thought of using a hack saw, but.... NO SAWS!! I didn't think of grinding it into a mini parting tool.
So, with the cherry end square to the protruding tube, I then took a rosewood blank and squared the end using my barrel trimmer - a brass tube ran loose inside as a sleave. I then CA Gel glued the blanks together and clamped. I parted off most of the rosewood, squared it to the tube, then repeated the whole procedure using my cherry lower blank. Part it off then repeat again using the opposite side of the rosewood blank. Finally part to length. The thin band is a tad thick, I think. I expected to need several tries to get it square so I left some contigency wood - but I got it much easier second time around.
Trim my bottom blank to final length, and glue in the tube.
For the back bevel, I turned the upper blank to 1/2 inch round and chucked it up in my drill chuck (I turn on a ShopSmith). Swung the tool rest sideways and cut the bevel with with the parting tool (finally found a use for it lol).
This literally took an entire evening just to prep the blank for final turning.
My learning lists of firsts:
First time parting square to the turning axis
First time using CA on wood
First time turning on the end of a piece of wood.
First time cutting a brass tube on the lathe
By the way, the cherry came from a tree in my brother's yard - taken down about 10 years ago. It was a short board I cut into blanks on an angle. The upper and lower are not from the same blank - they are the 2 short leftover pieces from either end of the board - I though there was a reasonable chance I would ruin the piece, so I saved the good blanks.
One unresolved trouble I had was tubes I glued in with CA Gel didn't hold. The CB parts held fine, but CA glued tubes broke loose on the barrel trimmer. I guess I'll stick to epoxy for now.
Tonight I played with CA as a finish. Not happy with the results yet, but I had to stop becasue my wife wanted to go to sleep.
