FormLabs 4: Second Visit Followup - In which I asked FormLabs to print some samples on the new Form 4, and I got to do further investigating. And, boy, did I find out some things. :-)
Printing Grimsmo Bearing Cages: P11 Wins! - John asked if we could try SLA-printing his bearing cages. It only took until P11, but it seems to be skookum.
Self-Checking Gages - We discuss two useful examples of self-checking gages, and several cases that are not!

Lapping From Ra to Rz - I was challenged by @proteummachining to start looking at Rz rather than Ra for surface roughness. Let's see why.
