OldMarine Posted December 26, 2017 Posted December 26, 2017 I use silicon in my BP prime for the very reason it is slaggy.

Svimmer Posted January 6, 2018 Posted January 6, 2018 (edited) https://www.youtube.com/watch?v=E7ILisymHm0 Made some spiderweb stars Edit: Made a starmine with plug https://streamable.com/z45i6 Edited January 6, 2018 by Sondre 2
NeighborJ Posted January 6, 2018 Posted January 6, 2018 made a EXTREME whistle rocket today with Calebs tooling. I think I used too much wax and it perhaps wasn't fully dry but it worked. It'll give me something to tinker with for a while. 3
Svimmer Posted January 7, 2018 Posted January 7, 2018 https://www.youtube.com/watch?v=QvyDUl8cE_M Made my first gerb tools
BlueComet24 Posted January 7, 2018 Posted January 7, 2018 Something I like to add to charcoal gerbs is a small lift charge in the bottom. I drill a passfire through the clay in the bottom and add about 0.5g of granulated BP and tape a cardboard disk over it. Before lighting these "jumping gerbs", I load them into a tube that's about the same height as the gerb. When the gerb burns down, it lights the BP which makes any remaining slag fire out the nozzle as a jet of sparks and makes the tube jump a few meters in the air! They're quite fun, and it just adds a bit of extra excitement to a pretty firework. 1

NeighborJ Posted January 7, 2018 Posted January 7, 2018 still dialing it in. It held together with 100% sali,the next step is KHP whistle mix 3
Svimmer Posted January 8, 2018 Posted January 8, 2018 (edited) https://youtu.be/x9J__stS_t8 Pretty surprised how good this composition burn it was not granulated.And im happy with the light it gives. Edited January 9, 2018 by Sondre
calebkessinger Posted January 9, 2018 Posted January 9, 2018 What ya gonna put it in? small report? giant one?
Svimmer Posted January 9, 2018 Posted January 9, 2018 What ya gonna put it in? small report? giant one? I dont really have any plans but i guess im going to make some small crackers or something. Just had to try the formual. It probably work as rocket fuel too so going to try that.
lloyd Posted January 9, 2018 Posted January 9, 2018 Sondre Sed, "...Pretty surprised how good this composition burn it was meal powder and not granulated.And im happy with the light it gives." Sondre, if only to "keep the language intact", I must tell you that IF it was 'meal powder', it most certainly was granulated. Meal powder is the 'fines' resulting from pressing and corning black powder, and is itself just very fine granulated powder. But, if it was anything else besides the fines from corning BP, if definitely was not "Meal powder". Did you perhaps mean 'rough mix'? (just the finely-milled raw chemicals mixed together) Lloyd 1

PeteyPyro Posted January 9, 2018 Posted January 9, 2018 I finally got the 48 DR-11, 3", & 4" mortar racks assembled & painted, with the new HDPE tubes. I double sealed the plugs and installed lower tube baffles between the bunged ends to reduce the risk of adjacent tube flashovers. 2
memo Posted January 9, 2018 Posted January 9, 2018 hand rolled a couple of hundred tubes 3/8 id x 1/2 od and some 3/8 x 5/8 for spolette tubes
Svimmer Posted January 9, 2018 Posted January 9, 2018 hand rolled a couple of hundred tubes 3/8 id x 1/2 od and some 3/8 x 5/8 for spolette tubesHow long did it take you ?
lloyd Posted January 10, 2018 Posted January 10, 2018 Sondre, sed..."...it was the powder right from the mill..". -------------Ah! A LOT of folks think that's "Meal powder". It's 'mill dust'. As before, Meal Powder is a specific thing; precisely, the fines from pressed and corned black powder. So... mill dust I can appreciate, because I've been known to have some interest in ball milling! <grin> Lloyd 5
Col Posted January 10, 2018 Posted January 10, 2018 (edited) Spent 6 hours cooking up 5kg of dextrin to go into a batch of tube rolling glue.Made up a glue sample to test the solids, spreadability and tack. . Edited January 10, 2018 by Col 2
