We reinstalled the primary mirror with re-machined clamp parts, and the new clamp parts worked well.

We're still waiting for the procedure to set the spring tension of the clamps right, but in the mean time we decided that 1/4 revolutions of the clamp screws after finger-tight felt about right.

Anyway, from there on we quickly set two auto collimators up, and roughly aligned the path correctly as per the procedure. 

Next we'll tune the telescope using a laser beam and mode master. That'll be about a day of setup and three days of going back and forth.
