Butchering a microscope stage to give you X, Y and Z plane movement in small controllable repeatable increments is a highly worthwhile exercise and thoroughly recommended.

It's an incredible luxury to have control over both your camera and your specimen in the x, y and z planes, but one that once you've experienced it, you don't want to be without.

Parts for a Microscope Stage

Microscope Stage

Microscope Stage, with the acrylic sheets I glued on with Araldite onto the actual slide stage showing at the front.

The partner to the microscope stage is the universal stage that is shown on the top.

My microscope stage consists of a broken used child's microscope (but one which has fine focus adjustment), an extra rack and pinion with coarse adjustment that I found on eBay, two 1cm thick pieces of acrylic sheets that I cut to size and a tube of araldite.

In a nutshell, I cut the top off the broken microscope with a hacksaw, took off the existing stage, glued the extra rack and pinion in between, then used an acrylic sheet as a new base (it's clear so I can throw flash light through it).

I then rebuilt the existing stage but instead of the stage being one used to move a microscope slide around, I glued a second acrylic sheet onto its side. This gave me a 1cm thick platform to then put my universal stage on top of.

Between all the various bits, including the universal stage, it gives me x, y and z movement for the specimen, but also the full four degrees of freedom to be able to twist, rotate and point a specimen mounted on a needle in any direction I want. Invaluable, as far as I'm concerned.

Be Careful!

If you're going to butcher a microscope and take it to bits, be careful - I managed to assassinate a perfectly good field microscope by messing with the grease on the rack and pinion. These bits of kits are surprisingly delicate and it helps to have a vague clue what you're doing before you lobotomise one. Using the correct grease is a start.

Buying Microscope Parts

The business end of the microscope stage - the controls on the microscope.

The double rack and pinion gives me a lot of flexibility, as does the re purposed slide stage which has become a perspex sliding table.

The yellow strips give me a reference point where I always start focusing from.

Obviously the largest part of the investment is the microscope itself. Ask for one that has smooth movement and no slippage in the adjustment knobs.

I initially hopes that the light from underneath (the condenser) might be useful for focusing but it was too big and bulky so it was mercilessly removed.

Future Microscope Stage Plans

The microscope base is a bit big and bulky so I suspect that'll be changed in the near future in order to have a sturdy base that lets me also put my flash directly underneath the specimen. At the moment the base gets in the way and I have to slightly angle it which to my overly extreme macro OCD mind is terribly distressing =)

I bought a microscope on Ebay with the intention of doing the same but to my surprise the microscope was in too good a condition to butcher. I found they can be converted without butchery. If you look to your right hand side there is flat bar that pokes out of the mounting stage. It has to as part of the side to side adjustment. I stuck a rubber onto it with double sided sellotape and an old polarizing camera filter to the rubber. That gave me a small rotating stage with XYZ positioning to the right side of the microscope with plenty of space above to mount camera and lenses with a framework clamped to the microscopes top bar.
