Hey there, here's it all in a Guinness ball so to speak. Modified wrist rocket to include four bands merging together as one, enlarged pouch, and a smooth guard that projects from hand to face made out of a military flack jacket and fiberglass sanded smooth and painted with enamel.
Fizzy balls from Guinness beer are fairly thick walled and make great coyote chasers or for plinking at stuff out where you are sure of your backdrop. I had the need for a nonlethal way of chasing away vermin and this is what I came up with. They are great fun but the comp filled projectiles tend to drift and loose accuracy over any real distance and sometimes fail to explode. At longer ranges, these failures are likely due to inadequate impact force, and being too light to set off the silver fulminate primer inside. The primers are glued in place using CA glue first, then the report composition is added thereafter. If I use any effects like spherical titanium or anything that will rattle around, I always use a filler to take up the head space that still leaves room for gas expansion, but minimal effect on the ratios in the composition.
I don't have a death wish, nor do I want any trouble with the law... I'm basically using them the same way as they would use California seal bombs, but for longer distances and for faster moving nuisances.
I tried a composition using lead dioxide from a lead acid battery and German black aluminum and with the extra weight, they acted like regular ball bearings with much less drift and had no trouble with duds. However, I have not yet found much on the internet about using such an oxidizer for pyrotechnics. It may be either unstable or otherwise unsuitable in some way, so I will soon began trying various mix combinations in tiny quantities, each in their own separate baggie, labeled and hanging out on the fence for days or however long I decide to leave them, taking note of any that disappear or go bang in the night.
Has anyone employed lead dioxide before for anything pyrotechnic? I remember using it in organic chemistry where it serves as a strong reducing agent for redox rxns, but it didn't cross my mind until I needed the weight. And it seems comparable in effectiveness to perchlorate in the same ratios. What's the scoop with it? It's cheap, it's abundant but not very 'Green' yet I would think it would compare to lead projectiles environmentally speaking... Except for it being much finer particles.
Thanks for your kind advice and information.
