Just check ebay once in a while. I've Paid ~30USD / per japan made goniometer. Take care to match nodal points.

I was just trying to be helpful, with luck you can find small ones for <$50.00

My setup (thanks Charles for the great idea). Only difference - I'm using soft ball needle instead the copper strip.. Before I tried micro stages, had a " rotatable goniometer" - small thing from the Stanley SU-100 door sensor, which holds/positions micro antenna inside the unit (was pretty comfortable).
But slide/clay/needle combination was the winner - very compact, easy to place around different diffusers, you can have n+1 ready specimens if you think, that you photo session is not fully complete yet, etc ...

:lol: It's a bit small, but yes it works! It's nickel plated so less sexy than most. It needs a square-bore tool to adjust - I made one from a brass tube. It has a better tilt range than most goniometers, but of course a short radius. The dark screw holes you can see adjust the stiffness of the slides. It's very solid.
Later a forum member sent me a base for it which gives 2 more degrees of freedom, making 5.
I believe it's designed for crystallographic measurements.

A Simple Horizontal Rig for Pinned Insects
Posted: Tue Dec 08, 2009
http://www.photomacrography.net/forum/v ... highlight=

Its pivoting “Stick Pin Sleeve”was made from a cheap kitchen cupboard spring loaded Ball Catch ,which has been drilled to accept a tube from a hypodermic needle.
This provides for both the adjusting of a “set” specimen to the horizontal plane and to rotate and tilt to the vertical. This can be done with your left hand when sitting at the bench looking through the viewfinder, it also allows ample tilting to one side so that specimens can be removed with ease and safety

The “Stick Pin Tubes” of various lengths are the next larger gauge of hypodermic needle secured by a soldered off cut of the locking screw of a camera cable release.

Pins of all sizes can be safely pushed into the wad of Bergeon Rodico that has been inserted into the open end of the tube, and when the Rodico is spent it can easily be removed with a small twist drill.

Very nice stage Chris! Looks like one fancy "CSI" bullet comparision stages?

I've purchased "classic" goniometers. 60x60 with 80mm WD and 40x40x20 with 60mm WD for 35 and 25 USD respectively. Those are amazing tools, i cant imagine how i've managed to take stacks without those now :)

I know what you mean.

When I was working crappy contract IT jobs, I learned a LOT about making stuff with PVC pipe.

First post, so apologies!

I use 2 types of stage. Very pleased with the 'EntoBall' from https://www.microscopesplus.co.uk/page143.html and the Lego Open-IMp described here https://zookeys.pensoft.net/article/4667/

The Lego was tremendous fun to build but it took over an hour to order all the parts!
