Mumbles Posted February 21, 2013 Posted February 21, 2013 I'd imagine that using a hardwalled casing on the inside in place of the kraft liner or at least inside of it or something would allow for the binary method. Handrolled bottom shots already use significantly less flash than a normal full size hardwalled case. Cutting the flash down even more doesn't seem ideal to me. There is a reason people get excited about bottom shots. I wouldn't want to deprive the people.
nater Posted February 21, 2013 Posted February 21, 2013 My idea was similar to using a hard walled casing, but I need to see if it works first. Let me test it some before I give out too many details. The only benefit would be building on sites where mixing flash is not allowed and when you don't have thick walled tubes available of the right size for the shells you want to make.
flying fish Posted March 7, 2013 Posted March 7, 2013 They work okay with BP, which I like the tone of better than flash. What do you think are the odds of the "book" not unfolding with BP? Obviously wouldn't want the core coming back intact, especially if it was a larger shell. Perhaps the odds are even greater with an inadequate flash that could "jet" rather than explode, but that's just my speculation.
nater Posted March 7, 2013 Posted March 7, 2013 I'm not sure, I thought about it especially after I fired some at a shoot last year and someone complained about shreds of newspaper on the shoot site. Although,they did say it was more newspaper than my small shells would have accounted for. I would think that with proper spiking, there would be enough tension all the way around the shell it would break everything. I'll have to pay more attention next time I shoot them.
AdmiralDonSnider Posted March 26, 2013 Posted March 26, 2013 I had trouble getting chipboard to lay down straight and tight, and I couldn't ever get what I felt was a tight enough roll with newspaper. The newsprint only process seems ideal from an economic standpoint, but as air is trapped inside the folded strips, is seems vital to use a lot of pressure to drive it out and make a tight roll.Now has anybody made them from newsprint solely?

Mumbles Posted August 7, 2015 Posted August 7, 2015 I agree. That video is a must own in my opinion. It's the perfect compliment to the descriptions in Pyrotechnica.
