Confused Monotype Pneumatics
Using a sports inflator needle to apply compressed air to each air line individually, I am finding several oddities. The first is certainly not unexpected: Several of the airpins are sticking. I think my best bet for these is to…
Monotype Pneumatics: Paper Tower air supply
Just for a lark, I tried connecting my Monotype caster to a compressed air supply, and found that the air connection to the paper tower leaked so badly that the (admittedly small) compressor could not keep up. I tried putting…

Monotype Pneumatics: Tubing repair
A previous owner of my Monotype composition caster had done a bit of a butcher job repairing a broken tube under the table. There were two soldered joints (using fittings not designed for solder joints) and two tees with capped…
Monotype Pneumatics: Quadding and Centering actuators
The Quadding and Centering system on the Monotype composition caster is controlled by two actuators on the paper tower. The one for Quadding is a simple piston inside the tower housing which causes the motion of the paper tower cam…
