A while back I was working on a pretty small (for me, that is) model that had me squinting when working on my Taig mill, even with the aid of a binocular head piece. At the time the article in HSM by Jerry Kieffer in which he showed how he used a stereo microscope on his Sherline lathe got me thinking.
Well about a year ago my brother-in-law gave me a 20x monocular microscope that had a focusing point about 3" from the lense - just perfect. A flea market find of a clamp from a heavy duty magnetic base and some Delrin? cut-offs from an auction gave me no excuse to dither any longer.
I wanted to be able to swing the microscope out of the way but not to lose the focus point when needed. Came up with this and probably went a little on the robust side. Thinking was that heft equals steadiness, and it works well. The black plastic machined like a dream and left a really nice finish. After all the discussion recently on these types of plastic, I still don't know what it is but the swarf smells like fertilizer.
The plan is to make a mounting base on my Taig lathe table as well so I can use this apparatus on both machines. Who knows, maybe also on the big lathe and mill as declining years take their toll.
