Quote from www.pyrouniverse.com:
Mines are basically a ground-level aerial shell burst that is directed upwards. The bottom of the tube contains a black powder lift charge, similar to that found in a shell. When ignited, the lift charge engulfs the stars in flame, igniting them as it propels them out of the tube in a V-shaped pattern.
I understand ecko has a great egg on mini starmines, but I decided to post my egg on larger starmines.
The Mine
Materials: 1. Thick Cardboard tube (PVC should work too) the size is up to you, I suggest trying different sizes and seeing the result.
2. CD Spindle (If you use a computer, you should have a few laying around)
3. Ram Rod that fits into your tube (I use the end of a screw driver)
4. Drill (with a bit just large enough for your fuse)
5. Tissues
6. Superglue/Krazyglue
7. Fuse (or sparkler)
Assembly
1. Cut off the pole on the CD spindle
2. Ram a few tissues into your tube then apply a lot of superglue. This forms a solid endcap
3. Measure how far into your tube the endcap goes with the ramrod then drill a hole just above the endcap
4. Glue the Tube to the CD spindle (with the open end facing up obviously)
This is one I made earlier… I decided to “pretty” it up =P
The Lift I will be brief here because you can find countless BP/Lift powder tutorials all over the net.
Materials: • Black Powder
• Dextrin
• Mesh/Screen (it doesn’t have to be super fine, a kitchen sieve or fly screen would work)
Assembly 1. Add 1-5% Dextrin to you BP and dampen with a little water
2. Press it through your screen so it forms into small grains
3. Leave to dry. The more Dextrin you added, the longer it will take to dry.
The Stars There are so many different methods and compositions for stars so I will just post a few links with good information.
I use pumped stars with just experimental blackpowder + coarse aluminum powder composition (they look pretty dodgy but I’m yet to find good chemicals)
Putting it all together With all the components done its time to put it together.
1. Insert your fuse into your mine
2. Pour your lift powder into the bottom. The amount of lift depends on the size of your mortar and how many stars you’re launching. If you are unsure I say experiment with small amounts and work your way up.
3. Gently drop your stars into the BP. I find sprinkling a little BP over the stars help ignite them. Again the amount of stars you use depends on the size of the mine along with personal choice.
4. Gently pack some tissue in the mine on top of the stars.
5. You’re done! Go set it off! (for full effect use at night)
Mar 09, 2008 7:35 pm - I had an egg on big ones I was going to put on here, but you got to it first. Great job. Thank you for posting a link to my egg, 5*.
Mar 09, 2008 7:38 pm - Alle, He didn’t make cut stars, he made pumped. He was just showing that I had an egg on cut stars.
Milky, don’t you find that filming star mines is a bitch? I mean they shoot up so fast and it’s hard to catch it all. Mine always end up getting off the screen.
true, but using wadding on TOP of the projectile is completely pointless. When I try this I am gonna have a sparkler fuse go through the top of the tube. Then ignite the stars. then go right through the wadding to blast the stars much higher into the air. Also, having light weight tissues on top of the stars will only slow down the stars by being in the way. 4* for the egg
