Did you turn away all the resin off the Bocote leaving just the resin on the band, then put a finish on it? or did you leave the Bocote also encased in resin?
Paul - I turned it all away. Initially, I rough turned the blank so it would fit in the mold. (That also meant more space taken up by wood in the mold, so less resin necessary to cast.) Once cured, I simply turned to bushings. Wood was bare. CA finish over all. Done.
When I do it again, I will not put the tenon for the art right at the end of the barrel. I will leave a little wood at one end, I think. The end of the cast resin is prone to be difficult to work with - if it was "surrounded by wood," I would need only worry about the face.
Disclaimers...
First - I turn bocote fast - perhaps 2200-2400 rpms, and I get a very clean, polished cut. That is way too hot for the resin. Married materials have to be respected - each has its own properties. That withstanding, and with time on my side, the next will be turned slower and I will finish with paper, not a tool. I also "flat sand" a lot. Softer materials don't react the same way, and I wanted a "flat surface." That might have been one of the success points of this pen. Hold the paper down like a shoe-shine boy with no fingers touching the work and try to stay "flat."
Next - I didn't mention that I had to sand everything the way I would normally sand a wood blank. Knowing that I planned a CA finish, I then also had to grit my teeth and wet sand and polish the resin strip portion...that said, I was adding water and polishing compound to the adjoining raw wood. It seemed to work, but I don't like the idea, and I was as careful as I could be to limit exposure to the raw bocote. The upside (in this case) is that bocote is a rosewood family member, so it is oily and resisted absorbing too much of the foreign liquid. Don't try this with pine!
Most - Once you cover a polished surface with CA, it will never look any better. Make the CA finish perfect as a bride's smile, the resin below still (and only) stands on its own. "If it ain't shinin', it ain't gonna shine better later, brother." End of sermon.
Now..."What's the next major problem, boys and girls?" I wish I had one of my own projects completed, but R&D is fun!
