will do, had to order the fuse though, and now with some of the wood cutting area's closed, i'm not sure we can get back to a really nice fir i'd like to try this on. But, i will ''try it, and report back'' if its possible.
No. While I don’t necessarily agree with what they’re doing here it obviously works. While considered an explosive BP requires resistance to explode. They seem to have mixed the two burn rates of BP in that last attempt. That along with not enough powder, not enough resistance caused the failure. The resistance is the wedge or perhaps just sand they used. For this reason reducing the charge by attempting to get a tinfoil envelope down a plunge cut is just a waste of room. safety: Anytime anyone says you should pack or tamp any gunpowder it’s time to quit. While it’s true they tamped old muzzle loaded cannons a bit that was necessary to get the powder to the end of the horizontal bore. Any perceived gain from packing powder is mute. It’s the force containing it that’s important. As for how far things may travel? Depends on the force behind it, time lapsed in the explosion, weight and the hand of God. I’ve seen homemade cannon barrels fly backwards 200 feet horizontal. Seen them launch 100 feet straight up. I’ve launched push lawnmowers 100 feet straight up. It can be fun, it can be educational. It can also be deadly if you underestimate it at any point.
True old style black powder is tamped in brass cartridges to reload and operate correctly. It was recommended to drop the powder load from minimum heights when dropping the powder into the cartridge. Tamping does change powder load density and burn rate characteristics, which effects pressure and terminal ballistics. Modern powder and most BP substitute is not nearly as picky because the chemistry and powder grain geometry help control burn rate. Since log splitting has no real terminal ballistics then we are really just trying to confine the powder to build pressure to make a wooden pipebomb. Packing the cut or slot decreases the area gas can escape so pressure can build faster with less powder. With enough powder you can create a Sonic choke where the gas can not flow any faster out the loading port and pressure will build with no tamo or wedge.
Ever seen anvils fired, it’s pretty cool. Blacksmiths used to do it in the old days to let people know the time. Kinda like the 12:00 whistle in the small town I grew up in. Ahh.... those were the days
I would disagree. Dropping charges, to my knowledge, is only done to fit more powder into a specific case. It’s still done today with some cartridges/loads using smokeless powder. I’ve done it on my competition guns, 6PPC burning N-133 mostly when trying to find that top node. The only real change from dropping/compressing is more powder per volume. Which will obviously change the burn rate slightly. The biggest change in burn rate and compression comes if you begin crushing the granules into finer grains. Highly unrecommended.
I’ve seen them launched. Is that what your referring too? Was in a movie, not real life. Dad would have killed me
