Plunger tube size comparison. More volume means more air being pushed, meaning better power/range.


Shell cleared out.


Lube


The lube (white lithium grease) prevents the epoxy putty from sticking to the shell, but allows me to push it hard into the shell to mold the epoxy. This is the easiest way to get a clean mold.




Epoxy putty molded support.


CPVC to stabilize plunger tube. The top spacer also helps control the plunger tube.


The top piece of CPVC stabilizes the plunger tube.


Holes drilled for mounting.
