New engine progress

Over the last few days Scott and I machined the pieces for a new 100N thruster. It isn't designed particularly efficently weight wise but is purely to test different configurations of catalyst pack.

Also I made a punch to cut out discs of silver mesh:

Punching more than one sheet by hand didn't go so well so I bought a press:

With which it was much easier to punch multiple discs at once:

The plan is to test the new thruster on thursday. I am not expecting to get perfect results first try but I want to start with more mesh than we need and reduce the number until we don't get complete decomposition.
