I have a nice big piece of stone art work that has a bi-metal

The bi-metal has died (too many 120°F day ?:-).

Anyone know where to obtain such a mechanism?

Surfing only produces complete units, not just the mechanism.

Ran onto a posted thread with similar need... NO, nada, none,
responses :-(

You might try searching some woodworking or crafts stores and look for
kits for thermometer, barometer, hygrometer stations.

Here's one:

You might have to buy a complete unit and pul the mechanism out, but for
$8, you might not get a mechanism much cheaper.

That's what I was thinking, as a back-up move.


The problem I see is that these units have a fixed degrees of rotation
per degree temp ratio. You may have trouble finding one that matches the
face of an existing instrument.

Already made me a cardboard template that I carry with me ;-) A
preliminary shopping tour shows that it must be a Taylor bi-metal
element. But I haven't yet found a sturdy one... everything is
plastic, without the bi-metal encased. I may have to patch-up the
existing one. Its problem is a warped housing (from the heat ;-)

...Jim Thompson

If the mechanism is still OK, find someone with a small mill and have a new
enclosure made (metal). That's what I'd do (always looking for an excuse to
make metal shavings ;-)).
