Here's a little idea stemming off a pen I'm working on which is a tube casting. I want the item/items cast on the tube to also be cast on the end of the tube, so I sealed up the end of the cap and pen tube on the JR Gent II.
Using some maple, I drilled an installed a 10mm tube for the cap and a 7mm tube for the pen section. The 10mm is 1/4 deep and the 7mm is 3/4 deep.
The wood was spun on the lathe so that it was just a hair oversize of the gent tube diameter. A tennon was then cut so that it fit snuggly 1/8" into the tube.
The inside of the tubes is sanded where the tennon is glued into the tube for adhesion purposes. The tube and wood is re-mounted and spun flush. On the cap, it is parted at 1/8 beyond the tube and on the pen it is parted 5/8 beyond the tube. While on the lathe, might as well rough up the tube too for painting.
There is a tiny hole in the very end of each wood cap because the bit used inside was a brad point. No problem, fill it with some thick CA if you are using a pourous material over the end. For me, I am gluing leaves on the ends which cover the tiny hole. If the hole was left open, resin would penetrate the tube and that's no good
! The leaves are thick on the ends of my tubes, but they will be spun much thinner after the pen is cast and the ends parted off the lathe. Now back to the saw!
