Assuming Bob sees the email, or has a good assistant, he'll send it free of charge. It would be silly not to.
I can't believe this. How much would an inch of pin stock cost him? I'm disappointed.
make the pins! If you are looking for a project. Just go to a hobby store for airplanes or model trains, buy the little lengths of tubing, and then go get some of that clothing dye from wherever that stuff is these days and dye the epoxy black! It's one inch, you wont need any fancy technique to get the glue down in there, just glob it on the interior pins, and fill it with your finger.
