Monotype piston rod—Mounted on mill, ready for cutting
After finishing one side of the extended-stroke piston rod for my Monotype, I took apart all the work holders and gave the mill a bit of a cleaning. The rod has now been clamped down to the milling table with…
Monotype piston rod milling half-completed

After determining that I had a way to drill the necessary holes without any new tooling, the repair of the threaded holes on the Latch Abutment (58H1) is finished. Even with the holes properly center-punched, I had a little trouble…
