Just measured mine.I've been watching this thread since the first post... What are the dimensions of the tin (major & minor axes of the oval, diameter and shape of the lens, thickness of the metal? Is the lens cover threaded?
Thinking about making one or two.
Thank you very much. I have a couple of lenses somewhere, not sure that I have a big enough piece of brass in that thickness, but that would be a good excuse to go and visit Metals R Us for the first time in years.Just measured mine.
Major axis 112mm.
Minor axis 78mm.
Depth 18mm.
The lens protrudes 5mm with a dia of 36mm.
The lens cover is a friction fit.
Metal thickness is about 0.5mm.
