The Gorton 3U pantograph engraver/mill I just bought needed a bit of fixing up. Some of the bearings in the mechanism were loose, things were dry (of oil) and pretty dirty, and there was a drive belt missing. I have…

More Equipment!
The main reason for my visit to Don Black last Friday was to pick up a new (to me) machine. This is a Gorton 3U pantograph mill/engraver, which turned up when Don and Craig were reorganizing their stock. This machine…
Monomatic Parts
I got a big lot of what appeared to be justification wedges for a Monotype composition caster from Don Black last week, many of them brand new, still in the protective plastic dip from the factory. It turns out, however,…

Measuring air valve shutters
Looking deeper into the poor airflow observed on my stock of surplus Matrix pneumatic valves, I did a subjective measurement of the airflow on each port, on a scale from 0 to 5, using a 20PSI supply. At zero, the…
Pneumatic valves for Monotype computer control

This week we had to get a fresh bale of bleached abaca pulp down from the upper tier of the racking in our store. This meant clearing a path for the forklift, which in turn meant moving almost everything. We…
