Digimatic caliper!

In the case. The rudimentary set in the middle is more of a carpentry thing, much less accurate (and almost ten times less expensive. It helped me along the way, showed me I needed more accuracy and will be useful elsewhere.)
Now to fiddle with measurements and determine if I can use the aftermarket clutch pack (clutch and friction plates combined) to fill the specifications of the machine. It’s likely I’ll cut my loses and order a stock clutch pack, settle for “good enough” as hitting spec is important with tolerance. (The clutch functions within specific tolerances, can’t be too big anymore than it can be too small.)
I’m not going to rack myself over this, but the potential exists that MINCX might take me to work!
