What airgun related idea did you cook up today?

  How about a 1377/22 XL and a C362XL.
Ditch the 1377 tube diameter, and use the same diameter airtube as a 2240.. that would create abit more air with each pump.. but how you or I would build such a thing idk.,Crosman would have to make new airtubes and pistons seals and such to build such a thing.
Just a thought

Bob Sterne has probably already done it.

He's made 2 I think. Great build threads to read if you can find them.

A 2260 tube might work. Or a disco or maximus tube if you can find one. Use a valve from the mk-177. Might have to fab a custom piston. Maybe a Benji 392 lever and link assy.?

Here's one to think about.

A hollow pressure chamber containing a small quantity of denatured hydrogen peroxide and a tiny, isolated pellet of a solid catalyst.  When the catalyst and the HP are brought together a reaction occurs.  The chief product of the reaction is high temperature steam and carbon dioxide.  Steam is naturally expansive.  You could use this to power a PCP.  Because of the temperatures involved there are firearm like challenges to be overcome.  How to contain and direct the steam I leave to someone else.
I was trying to think up uses for a small Walther cycle engine and this occurred to me.
