I needed to get decent images off a microscope in fairly short order. Though I was in a “rush”, it still took a full day to get to a working solution. It is still incredible to me how much time it takes to make something that doesn’t obviously suck.
This was made with aluminum bits from my scrap pile, some saved brass thumbscrews, and a Manfrotto Nano clamp. It still takes some jiggering to get the perfect position, but once it’s set, it is very solid. I will try to get some drawings up in the not-too-distance future.
These clamps cost about $35. I had one left over from another project. If I was a *real* machinist, I would have made the clamp as well, however not doing that probably saved days at my speed.
Above you can see how the clamp spacer overhangs the clamp and slides in a slot to prevent the platform from rotating even when the thumbscrew is loosened.
