to mixing them together? In my experiments so far, I am using a VERY thin layer of inert material (Saran wrap or similar) between the initiator and
charge, just to prevent any possible incompatibility. it is also convenient, as it allows me to make the main charge and primary in separate tubes
and just slide them together at the end, after any pressing. The smaller initiator tube fits easily in the larger main charge tube so minimal force
is required. Then i use epoxy to hold it together and add additional strain relief on the fuse. I'm a little paranoid about incompatibility with the
epoxy however, and looking into non-amine hardeners. |
The firecracker is ETN so it's the same power however this is for my paper firecracker tubes only. My det tubes use Melt-cast ETN, powdered ETN and
NHN all pressed one on top of the other. ETN and NHN do not negatively react with one another so no need to separate them. What I have done here is
made the most powerful firecracker you can make which is safer to mix and load than flash powder. Even if you filled the tube with LA, this cracker
would be more powerful, and that's saying something.
What makes it powerful is how the melting ETN and NHN combine to form a solid that when properly heated detonates with a Visco fuse.
