Pretty much self explanatory, but it's been to long since I've been fired a spud gun so I did something about it.On a supply run I went to a Hardware store and picked up a few bits a pieces...It all came together so easily...like I'd done it all before.

The mighty cannon features:
Primer stains.
100% Storm Water PVC construction,non pressure rated.
Ignition hole in cap for the long nosed BBQ gas lighter(since reduced to a melted non working BBQ lighter)
.9:1 Chamber to Barrel ratio by volume.
65mm Bore
100mm chamber
No air:fuel mixing device, chamber chain to come :roll:
Thin layer of red centre bull dust.

At the moment jack I'm using some alcohol body spray,alot of things are in limited supply or very expensive.I do have plans for pneumatics though as sending inert fittings by air is permitted but not volatile substances/fuels.

This hobby never dies,just progresses mark.Pneumatics should be next on the cards!
