174: Chinese ER collets - not EDM - full of burs - needs hand finishing work. I found a old rusty feeler gage blade - roughened up the edge on the grinder - worked pretty well to file out some burs.
173: Surface roughness tester Surftest 211 Disassembled Not the greatest design for the time - 4PCBs too many connectors. No need for two uP. All it needs to do is preamp, motor voltage, A/D UI. Don't recommend Mitutoyo - they go after people sharing manuals, no parts support on older units.
