I made up a little tripod thing for my microscope, but they ended up with a wrecked Buck adjust-tru chuck when I got my lathe. (Shame about the chuck, but the body seems to be twisted, won't hold anything straight.) So, it makes a great base for the microscope. It does take up a lot of space in the bench, though. > I wonder how much doddering around it would take to > put it right on the pan-a-vice I am using?

Cut a piece of PC board material to fit snugly around the bottom of the microscope, etc. For some of them, rings can be cut on the lathe, and then cut a ring just into the copper to make a pair of isolated concentric conductors. Power with a 12 V wall-wart, use 1K resistors to supply each LED. I use leaded LEDs, not surface mount, so I can point them at where the microscope looks. > What did that scope cost?, & URL where I might source it please, Jon. > At home, I have an old Olympus, I got it for, I think, around $130 many years ago through an eBay seller who was in the microscope business.
At work, we have a Chinese one similar to this: http://www.ebay.com/itm/7X-45X-Simul-Focal-Stereo-Lockable-Zoom-Microscope-on-Dual-Arm-Boom-Stand-/252629277518 Ours has a larger stand with longer arms, but the microscope itself is the same. They have a fluorescent ring light for these that hangs WAY below the microscope, you lose about an inch of working distance. So, I got rid of their ring light and put my own on, very happy with it. it fits around the objective lens section of the scope, so you don't lose ANY working distance. Sometimes my hands bump the LEDs and I need to re-aim them once a year or so.
