    Visco Fuse

    Excuse me, i wasn't logged in.

    Visco Fuse

    Make a machine that makes the fuse for you!! I do that for blackmatch, a bobine of cotton string is lying in a bah with dissolved KNO3 in it, the string goes true a paste of blackpowder(i use a silicon tube)and comes out coated with blackpowder, i make about 5 meters in a minute
  3. You can work that out by using stoichiometrie, S also gives some gas as you said but it actually slows down the mix a bith, in case of blackpowder it eliminates the precipation of carbonate so the mix will burn slower.
  4. If you do that you will overfuel you're composition, sulfur has only one goal and that is to make the sas more sensitive(flahs more sensitive :shock: )
  5. Go to brainfever his site, bridgeless eletrical igniters, i make them to for firing aerial mortars and stuff, very reliable and easy to make, Blaf are you sure 1.5 Volts is enough? I use 12 volt over a distance from 20-30 meters

    Visco Fuse

    Sure, if you pay me the send cost and the visco fuse, why would you need that VISCO if i might ask?

    Rookbommen

    Compositie's met suikers en andere koolwaterstofketens zullen altijd traag branden omdat ze eerst moeten ontbinden voor ze effectie reageren, voor snelle composities heb je C, Al of Mg nodig als reductor.
  8. Glad for you you haven't lighted one of those devices, tourbillions give loads of sparks, so does the tail of a rocket, I haven't fired anything here for the past week cause of the huge heat. I am waiting for the rain to come so i can start working again.
  9. At night on the beach, big open place and allmost no danger of fire?
  10. Ba(NO3)2 can be made by 2 easy ways(the ways that i use and know) First one: BaCO3+2HNO3--->Ba(NO3)2+H2CO3(the H2CO3 will most likely fall apart in H2O and CO2) Second way: BaCO3+2NH4NO3--->Ba(NO3)2+2NH3+H2CO3(watch out for ammonia vapours, the H2CO3 will most likely fall apart to) BaCO3 can be bought at several places, just search a lot for it
  11. Ba(NO3)2 isn't hard to find or make,if you want a flash core for the brightness of flash then i recommend you to use KNO3/Al/S flash(slow and quiet bright) EDIT; I am from Belgium
  12. Ja die is er maar de procedure is niet echt veilig, CaC2 kan je gewoon kopen in de betere tuinwinkels...
  13. Stable flash, Ba(NO3)2/Mg
  14. I am free friday afternoon, i'll do my stuff then to learn in the weekends, i think this rocket will lift about 50 grams of payload, not much but it's ok for such a small rocket

    KClO3 en Suiker

    Die ziet er een stuk beter uit, natuurlijk is deze reactie sterk vereenvoudigt en ontstaan er nog andere stoffen.

    KClO3 en Suiker

    Richard zijn post is niet juist, je mist een zuurstof atoom
  17. The rocket was in the experimental fase, maybe i'll try to take payloads up on friday(exams now) But i am quiet satisfied with the result now.
  18. very funny, He flew over hundred meters That is a very healthy height for such smal rockets

    KClO3 en Suiker

    Buskruit hard aanrammen eventueel met 5 pct dextrine

    KClO3 en Suiker

    Je moet weten hoe de reactie verloopt, dus KClO3 geeft zijn O moleculen af en C neemt ze op, nu moet jij uitrekenen hoeveel mol KClO3 je nodig hebt om alle C te laten reageren.
  21. Use argon if you can find it, I haven't made MgAl yet (i can buy it) so i have no idea if it will work.
  22. Exhile

    KClO3 en Suiker

    Maak H3(suiker moet eerst smelten voor het reageert) Uw verhoudingen liggen ook niet juist, reken eens stoichometrish uit wat de correcte verhoudingen zijn. Om nu terug te komen op H3, H3 is een mengsel van 75pctKClO3 en 25 pct C, Als dit mengsel goed gemengd is zal dit vele malen sneller branden dan BP. Een pyrotechnische sas ontploft trouwens niet, het is door de gasopbouw in een huls die plots vrijkomt dat je een knal krijgt, niet door de deflagratie in de open lucht(opgelet flash kan DIT wel doen in te grote hoeveelheden)
  23. The Mg/AL there was in flash, not in dragon eggs, if it was for the MgAl to crackle, then they would never but NEVER put such a dangerous component in a pyrotechnical sas unnecessary
  24. I recommend modified meal powder, more charcoal and less sulphur, slightly wettened with acetone/water mix, yesterday i made a rocket who got far over 100 meters of height.
