That looks great, very classy. What was the size of the blank you used? Was it round or square? Does it seem heavier than wood or acrylic? Was it hard to sand and polish? I would love to have a pen like that and will have to try it someday. Thanks for posting it.
I purchased round 7/8 x 12" 6061 aluminum rods to make the blanks.

I'm sure you can find it a lot cheaper elsewhere, even as scrap material.
Turning it is a long and painful process. Painful because those hot metal shavings go to your arm and hands and burn you. (Long sleeves recommended
) I would go with a thinner rod next time to save time effort and tools edge. Drilling time is longer also but went straightforward with a 10.5mm drill on a drill press. I used Gorilla glue to glue the tubes because I felt they were a bit loose.
Sanding and polishing was not that hard, but turning is. It takes much longer than wood and you need really sharp tools. I added CA because someone here said that he was not happy with scratches and blemishes in one of his aluminum turnings. It may have not been necessary, but I think it won't hurt either.
Thank you for your comments.
