Spindle Micrometer Stop

To make a set of 10 pushrods for the Edwards Radial 5, I needed to turn ball ends on both ends of the material, to a set length. This was the driver to make a spindle stop. There are plenty of designs for spindle stops out there, such as this one from Ron, but most are designed to be set to an existing known length, rather than set the first length as well.

For this reason I designed a micrometer head into my spindle stop.

The 7x mini lathe has a 20mm spindle bore, and I wanted a metric micrometer.
