I am just beginning to assemble a "Stellaphane" type tester with
some machined aluminum and brass parts ( I have spent the last week
machining these - I am not a machinist), rather than the wood mechanics.

I am using 3/4" birch plywood with a nice polyurethane finish and a
metal vernier mechanism and slide arrangement. My stage
"faceplate"  is 1/4" delrin sheet rather than 1/4 "
plywood.

Any ideas or improvements on the light source and slit arrangement or is
the published design good enough. I am trying for a more accurate design
than the basic wood design.
