Recently found a great deal on a Swiss made Fisso flexible arm( think Noga on steroids ) indicator stand on eBay. It had suction cup base on it, so it went in the drawer for other things, and set to making a proper base for it.

Squared up a leftover chunk of Dura-Bar that was just about the right size. Since the Fisso arm is metric, the base was done to metric dimensions as well. 100mm x 70mm x 25mm.

Then added scallops in the sides, to make it easier to hold on to.

Drilled & tapped the top for the M8-1.25 stud on the flex arm, and drilled reamed four 3/8" holes in the bottom for carbide feet( the only non-metric components ) Before pressing in the carbide feet, I used the rear to holes to act as a pivot guide to round the corners on the belt grinder. Will leave the front surface flat/square, as I may eventually add a radiused projection, so it can pull double duty as a squareness comparator. Used Oxpho-Blue to cold blue the base, and pressed in the feet. Still need to surface grind them to a common plane, but that will have to wait. Rearranging the shop a bit, and want to wait until the surface grinder is relocated and leveled. Should work great, and be much more repeatable when using a tenths indicator, compared to a Noga. The adjustment mechanism in the Fisso is far superior, and it's just more robust in every way.

Great upgrade - all the way 'round. How did you source carbide feet?
Thanks. They were an eBay find. They're made by Sandvik. Diameter is .3765" and about .340" end to end. Spherical on one end and flat with a chamfered edge on the other. Just about perfect for hardened feet, or contact points for a hardened adjustment screw to bear on. They were $5/ea, but way more convenient/faster than hacking up and grinding old end mills.
