I was fortunate enough to have a piece of genuine Plexiglas brand acrylic from which to forge the coilform. Since Roam & Haas got out of the Plexiglas business in the 90’s, I don’t think you can get such acrylic sheets under that name any longer. Sure Lexan is harder, but Plexi is really easy to work with. If you want some Lexan, buy a Nalgene bottle. Using acrylic for the coilform even more strongly forces me not to use cyanoacrylate to bond the coils together. I must keep looking for an appropriate adhesive.

Here are the pics. I used a precision hole depth gauge to measure the thickness of the pieces because I don’t have a good precision (or well any) caliper.

I need some good glue, and an appropriate applicator to do the layers of the coil. I’d like something similar to the tiny applicator I used to have for model-train oil. It was like, a squeeze bottle with a long thin metal tube. Maybe a brush on thing would work too. Also I need to buy the bolts I will hold this together with, as well as the whole galvanometer frame.
