well i got a 50 mm outer barrel to sleeve nicely over 40 mm barrel
and a prototype grenade cartridge made up
i still need to do a few jobs on it such as glueing and shaping some pieces but overall the barrel is mostly done

this is the inner barrel unassembled


this is the inner barrel assembled and note on the far left is the grenade cartridge


muzzle end


and breach end


what do you guys think? and tips before i continue?

Looks good, I like the idea!!

update: i fixed on a thing to make the grenade cartridges fit centred

and attached a small fan to the receiver end of the cannon







still need to glue and finish the receiver end ...
