New Advanced Combustion

[Spitfire]

This is my 3rd Gun, but first proper advanced combustion.

The barrel is 2m long and 50mm in dia. It is sleved for golf balls.

Chamber: 110mm Class 9, pressure pipe. and is 35cm long.

It has a chamber fan, and a propane metering system.





How the fuel is injected into the chamber:






Duct tape on the batt box was a quick field repair:




Golf ball vs. Corrugated iorn


It shoots golf balls round about 400m
Any suggestions and comments are more than welcome

Very nice combustion for only being your third!

Lovin' the shoulder strap and is the pipe painted blue or did it come like that? I notice the interior is blue also.

Sweet damage shots the only thing I can see to be improved would be to glue in your fan so it doesn't get blown out

This is a really good gun i think the trigger setup is good for shoulder or hip firing the only thing i would do is put a removable ball valve for ventilation

That'a unique location for the fueling system, I think the advantage there would be weight balance. It also makes for a trim combustion chamber section. No breech load option or quick change barrels here though.

I like the guitar strap and the good barrel length. Obviously you know you need to do something with your ignition module mounting, so I'll leave it at that.

Overall good effort, nice performing gun.

The pipe comes as blue, most pressure pipe here has the blue colour.
Strap is a old police belt of my dads.

The fans has a tight fit in the chamber and doesnt move when shooting.
I cant move the battery box as there is a shortage of space, nd wires

The barrel can be quite easilt removed, as the propane system is mounted on a seperate piece of pipe, and The hose that comes from the meter has a threaded hose nipple, which is easily removed, provided you have the right size spanner with you.

Thanks for the comments
