This is a work in progress. I have used Patrick S. Parson's SE2000 as the model for this launcher.
I plan to use a 3/4" Quick Exhuast valve as the trigger. I also plan to use a barrel extension for longer lengths.
The launcher is not yet completed. Note that the pics included show a full cleanout assembly, but I am still debating on whether to just use a cleanup plug (ala Spudzooka). That decision will, of course, have an affect on how far down I glue the barrel inside the chamber, so I am at a standstill. Once I decide, the launcher should be completed soon thereafter.
Note that my piston is only 2" long and has no "O" rings nor equalization port. I don't think I will need "O" rings because of the small gap between the chamber and the piston. The blowby should be negligible. I will find out more about that as I complete the launcher. |
