By way of introducing and welcoming our distinguished new member, Richard Coyle @racprops, I thought I would mention one of my favorite props he built for the TOS movies: the medical scanner Chekov uses to scan Klingon blood left on the transporter pad in STVI.
It looks like the original was made partly out of a hollow cylindrical body that was put on a mill in an indexer and then those lines made with a ball-nose end mill.
But what about that clear part at the end? Was it a found item of some kind?
And how did you make the conical bit at the other end? I don’t think I’ve ever seen stock plastic sold tapered like that. Was this something you machined to a taper on the lathe?
I can’t want to learn more about this one.
