So the next step from the design was to setup a datum and gig.
$100 of
one inch extruded aluminum profile and hardware and then the hard part,
centering cones. Well that was actual a deal. I found a place that sells
plastic balls for fire works shells. The shell has a center hole I
drilled to 1/4th inch and then I made a plywood circle base some Crazy
Glue and washer and these haves make fantastic centering cones.
