I was wondering about making a coax indicator. But a dial gauge mount
that can be used while tools are in place seemed a useful bit of kit to be going on with.
I marked the shape of the spindle clamp out on bit of ali a few years ago, but I have other plans
for the bit of metal so kept putting this off, Finally thought it would save a lot of messing about
so I cobbled one together with bit's of scrap.
