One thing I plan to change pretty soon is the way the chamber seals up and the way the bore is recessed into the chamber. Makes loading a spud a right PITA. But for other projectiles it's perfect as is.
Other projectiles?
I've got some destructo tests planned against jugs, sheet metal, OSB, etc. Just need to find a bit of play time.
The 6-32 bolts that form the spark gap are sealed with rubber washers, metal washers and nuts from the inside. They come into direct contact with the igniter so no wires at all on this one. Handle comes off from the outside (double nutted bolts on the chamber) and the ignitor fits into the handle with no modifications.
Like I mentioned I want to improved the breach loading action and I think the way to go is to make a short section of 4" with a permanent cap on one end and a female thread to solvent weld on the the other then extend the bore with a coupling and that would have the bore stick out of the chamber to aid the insertion of a spud.
I have more handle ideas percolating, just need to find some "me" time to get into them.
The thing needs a sight on it too, now that I have some projectiles that fly true I can start dialing it in.
The bell reducer on the front has been filled with epoxy after the 2" pipe was slipped through and glued into place to eliminate that possible weak spot. I used West System epoxy mixed with colloidal silica and filled the entire "funnel" shape.
In the chamber I used by blocks stuck on with foam tape to stabilize the bore.
A fan or other way of purging the chamber would be nice, but space is pretty tight.
