I'm trying to locate a spinning stage slide ringer. My use for the spinning
stage is to ring with varnish the cover slip of slide mounts of parasitic
wasps for use in a taxanomic study. The stage will make ringing much
easier, and should actually be faster and neater than trying to paint a
circle around the cover slip, especially when doing hundreds of mounts.
The one I have been told about is an oval wood platform, 8 inches by 4
inches, and 2 inches high. On one end is a round brass stage mounted
on a ball bearing so it's free-spinning. On the stage is a clip, and in the
center of the stage is an inscribed circle the width of a cover slip. There
may be other models.
As yet I've not been able to find a supplier. Will some one please pass
along the name of a supplier for the spinning stage?
