- Until now I have used fine pins in needle holders for moving things
around under the microscope. I even managed to put a small hook on
the point of a pin, this proved to be a very useful tool.
Inspired by a recent post I am going to try making some different
tools. I have found two problems with mounted pins, one if you are
not careful the springyness in the pin can cause parts to be
caterpulted into space, and small things tend to stick to pins, I am
talking about working on tiny dry objects here.
I had a thought this morning, could I use fine fishing line instead
of pins, so I tried it. It seems to work well for replacing strait
pins, things don't seem to stick to the line so easily, and the give
in the line means you can press and make it lay flat thus holding
parts down without too much pressure. Has anyone else tried
alternatives to micro pins?
My next challange is to make the 'Y' shaped manipulators suggested in
the earlier post. I will try both pins and fishing line and compare
That should take care of holding things down, the next chalange after
that is to pick things up, a hook could be used to move things.
Tweezers are just too big and clumsy. Are there any simple designs
out there. I thought of something like a 'Pearl Catcher'. A bunch
of two or three springy pins etc. inside a sleeve. The pins tend to
bend outwards when they protrude a long way from the end of the
sleeve, thus opening the catcher. When the pins are drawn into the
sleeve, or the sleeve is pushed forward over the pins, the tips of
the pins come together as the length protruding from the sleeve gets
shorter. I can envisage squeezing a trigger on the handle of the
tool to open and close the minute jaws.
After that there are miniature knives and scissors to think about.
