lloyd Posted June 30, 2017 Share Posted June 30, 2017 Hey! That looked like a good, clean lift with good ignition! Congrats! Lloyd Link to comment Share on other sites More sharing options...
Tourbillon Posted June 30, 2017 Author Share Posted June 30, 2017 (edited) It's weird what happens when you listen to the advice of the experienced, thank you guys for the help. I'm going to eventually grow the mines to 4". In the meantime a successful (functional) first build has definitely given me confidence moving forward, hopefully from mine to shells.

Tourbillon Posted August 27, 2017 Author Share Posted August 27, 2017 (edited) Got around to making more 1.75" mines. Made the "bags" from scratch this time. 7 grams BP lift Stars rolled to Approx. 1/4" primedThis time I tried bedding the lift in rice hulls to deter the stars from migrating under it.Finished product.

NeighborJ Posted August 27, 2017 Share Posted August 27, 2017 Nice looking mines. Are you concerned about flaming fallout from the rice hulls? I've only made a few but I used a 2 ply piece of toilet paper which I split into 1 ply for a separator. Post the video. Jason Link to comment Share on other sites More sharing options...
Tourbillon Posted August 27, 2017 Author Share Posted August 27, 2017 Thought crossed my mind. Just figured I'd give it a try and see what happens. Link to comment Share on other sites More sharing options...
OldMarine Posted August 27, 2017 Share Posted August 27, 2017 I usually make my 1.75" mines from toilet paper tubes using the perforated discs from Caleb I press the disc down over the lift and then a tiny piece of shoe box tissue over that to stop migration during handling. I usually use a bottom disc as well just for looks. And here's my favorite mine pic ever. My son and granddaughter watching: 3 Link to comment Share on other sites More sharing options...

Tourbillon Posted August 27, 2017 Author Share Posted August 27, 2017 That is a very nice picture OldMarine. I'm trying to keep construction simple so I can build them in bulk. I eventually would like to fire lines of these in volleys to make a ground up wall of stars (ergo no piston). When I get around to making BP Coated rice hulls I'm thinking if I coat the hulls lightly to increase the volume I can just fill the bottom of the mine completely with lift.

Tourbillon Posted August 29, 2017 Author Share Posted August 29, 2017 Any guidance on star size and lift percentage on a 3" mine? Link to comment Share on other sites More sharing options...
Mumbles Posted August 29, 2017 Share Posted August 29, 2017 I like 10% of the mass of the stars/inserts as 4FA personally. Probably use about the same size you would in shells. Something ballpark 1/4" color, 3/8" streamer. Link to comment Share on other sites More sharing options...

The TP tubes can also be used for cylinder shells and headings since they are loose enough in a mortar to allow paper and spiking. Though I'm building 3"-4" shells and cylinders now I still crank out the small ones because they take so little material to build and I have limited production capabilities for now.
