Dischargers, smoke generator, 4 inch

[David Dunlop]

Chris.

Nothing fancy as these dischargers were all based on some form of a .303 cal rifle from which the breech and small section of the rear end of the barrel were retained. There were no modifications done to the bore diameter. The Ballistite cartridges were designed with more than enough power to get the job done.

I suspect you might be thinking of blank firing adapters that are fitted to the muzzle of automatic weapons to permit a gas pressure buildup in the barrel of the weapon to enable the action to function properly. Trying that with a Ballistite cartridge would be outright dangerous.

Thanks guys. So if I'm reading this correctly, we're saying the original hole size through the adapter is about 5/16" which is close to .303? - Chris

I'll measure one of mine and get back to you.
I have one without the canister barrel on it right now.
Stay tuned.
cheers,
Warren

addendum: THIS IS FOR THE ROSS ACTION.
the barrel ID is .305 in. and a barrel length from the witness mark of 2.68 in.

Notable on some of the examples I have seen is that the bore is nowhere near centered on the stub barrel. It's almost like they cut the barrel, and chucked the receiver in a 4 jaw chuck and made the two levels of thread (smaller dia thread for the discharger cup, and larger diameter thread for the large retaining nut). Either that, or if they chucked the ross barrel, it was not straight in the chuck.

I had a machinist friend make up a bunch of the nuts for the dischargers. We found that there was actually variation in the larger diameter thread to the point we had to recall the first batch of nuts and have them re-worked. The threads on the barrel at that portion are actually a but tapered.

I still have nuts available to sell for those that need them, and still have the PDF that I can send out to those that want it.

Awesome sauce Warren, thanks a lot. Where else but this forum could somebody say "oh yeah, give me a few minutes to go look at my super rare, original and get a measurement for you."
Next I'll see if my generic Harbor Freight floor drill press has the gumption to sneak up on that diameter. I'm sure I'll end up pre-drilling with multiple smaller bits first.
I appreciate everybody's help.

Does anyone got drawing of smoke discharger bracket, please? Side view preferably, I need to get proper elevation of the discharger. Thanks
