garyrapp55 Posted July 8, 2012 Posted July 8, 2012 If we pipe blackmatch to restrict available oxygen for increased burn rate, why can't we just lay blackmatch inside a piece of masking tape rather than rolled in kraft?Gary
Xtreme Pyro Posted July 8, 2012 Posted July 8, 2012 If we pipe blackmatch to restrict available oxygen for increased burn rate, why can't we just lay blackmatch inside a piece of masking tape rather than rolled in kraft?Gary That should work just fine. Before I had access to real quickmatch, I used to put a train of BP down the center of a piece of making tape, then fold it in half. Works just as good for shell leaders.
Xtreme Pyro Posted July 8, 2012 Posted July 8, 2012 What do you mean by "real quickmatch"? By real quickmatch I mean commercially made, 5 strands of blackmatch down a kraft paper pipe.
BJV Posted July 8, 2012 Posted July 8, 2012 What do you mean by "real quickmatch"? Pick this up a couple of weeks ago. "real quickmatch"Here is 820ft.BJV
dagabu Posted July 8, 2012 Posted July 8, 2012 Pick this up a couple of weeks ago. "real quickmatch"Here is 820ft.BJV It's the best stuff they make right now, made on the same equipment as the blue PyroFormax QM from a few years ago. I think there is some pot perc in there myself where the blue stuff was all BP. XP, that is sticky match, it's sold here commercially as well mostly for lance work. -dag
Potassiumchlorate Posted July 8, 2012 Posted July 8, 2012 (edited) I haven't tried that yet, but I have some 20 meters of it, I think. I still use the thick stuff with the yellow pipe. It's strong but almost too thick for smaller shells/mortars. You can actually use a string of fine BP in masking tape or similar as quickmatch, but it feels more reliable with the commercial stuff.

dagabu Posted July 9, 2012 Posted July 9, 2012 Thanks Dag, I knew it had a name but I couldn't remember. My wife and I even did some experimenting (not the kind some of the teenagers did in a trailer though) with QM, visco and sticky tape in the middle of a shoot this past Friday due to various questions as to how a delay should be built into the show. I know that sticky match takes fire from sparks with no resistance and so it is used on lance work where the sympathetic fire is actually helpful so we did not even try it. There is red and yellow visco (awful crap IMHO) cheap green visco (my favorite), kraft QM made locally (my last choice in a show) and the various plastic coated QM made in China, comes in yellow, blue and red coverings. Of them all, only the plastic coated QM is worth a damn in preventing accidental ignition as the plastic appears to eat up the heat from embers while the kraft QM outer jacket burns very well allowing fire inside within several seconds. The test involved 4FA from broken 2-1/2" ball shell lift cups and sealed QM and visco all sealed and set 6" from each-other vertically 2" away from a trough of the BP taped to the end of a large cardboard box. The yellow and red visco was first by the beginning of the BP followed by the red QM and green visco and ending with the kraft QM. The red QM and the green visco did NOT light from the BP or from the other QM hanging along side. The red and yellow visco both lit after about a second of delay and the kraft visco lit off after about 10 seconds where the outer jacket slowly was ate away by embers. For delay, we used masking tape and zip ties over a s fold in the red QM. The delay for the tape was very short, perhaps 1/4 second and the zip tie was perhaps 3/4 second and was much more reliable. And just to kick you all in the craw, we completely abandoned bucketing QM and have taken up a new process. Using a punch made from an eyelet pliers, we punch two or three holes through two pieces of QM that have been taped overlapping each other Sadly, persons with much more experience then I made the decision to use the red visco... You guess the outcome. -dag
Mumbles Posted July 9, 2012 Posted July 9, 2012 One problem I have with masking tape (and most other tapes actually) is that it likes to leave molten burning or smouldering remnants all over the firing area and fall out area. Your mortar could potentially contain these smouldering bits, which would be problematic if reloading. If you manage to tape the blackmatch too well, it can also begin to burn like visco instead of quickmatch, which could ruin timing. It may not be a problem with blackmatch, but certain tape adhesives have been known to cause issues over time with certain compositions. Duct tape adhesive in particular is the one I've been told about.
Peret Posted July 9, 2012 Posted July 9, 2012 Quickmatch doesn't work by restricting oxygen - it works by containing the fire, which then heads on down the pipe and ignites the match all the way down. Quite a lot of pressure builds up in the match pipe - I did some tests and the flat pipe inflates instantly into a cylinder. If there are constrictions where the pipe can't expand, the match burns slowly through those sections. Taping the match would, in my opinion, have that effect, unless it was loosely taped and the edges well sealed.

Yes, but only for a very short time, the tape does not restrict the ability to inflate, it just establishes two pinch points for the fire to negotiate around. Zip ties actually restrict the ability to expand and thus slow the gasses down as well. -dag
dynomike1 Posted October 1, 2012 Posted October 1, 2012 Well it is raining here today, and i decided to make some black match (21yds.). Back a couple years ago i made some to set off my cannon, didnt have bp so i tried 777 and it seemed like it worked pretty good except when my slurrey got dry and i got white spots in some of the string. But anyway i have a hole case of art straws recon i could tape them together and use them for quick match? I think that i would probably have to flatten them to work better.
dan999ification Posted October 2, 2012 Posted October 2, 2012 roll some match pipes, you can make 50 mtrs of qm in a few hours start to fininsh, mine works the same day but better when the pipes and match are fully dry. Dan.
dynomike1 Posted October 2, 2012 Posted October 2, 2012 (edited) I guess art straws are out? What do you mean by match pipes? Edited October 2, 2012 by dynomike1
mikeee Posted October 2, 2012 Posted October 2, 2012 Dynomike1, You can buy match pipes, or you can roll your own "match pipes".Instead of buying quickmatch, which can be a pain in the ass.You can buy or roll your own match pipes and install black match into the pipes.Thundervalley, Pyrocreations, and Pyro-Direct sell the match pipe. Mikeee
Peret Posted October 2, 2012 Posted October 2, 2012 Home made match pipes: Cut strips of kraft paper about an inch wide, fold in three longways, run a glue stick down the flap and press closed. When the glue is dry, less than a minute, you can squeeze the tube open and thread black match through it. It isn't the strongest - if you want strength cut the strip 2 inches wide and fold in six - but it works fine for launching shells, it's a heck of a lot cheaper than buying tubes and a lot quicker than rolling them.
dynomike1 Posted October 2, 2012 Posted October 2, 2012 (edited) I guess my question sounded kinda dum but i am not quite up on terminoligy yet. Edited October 2, 2012 by dynomike1
Livingston Posted October 25, 2014 Posted October 25, 2014 It's a pain in the in the buttocks to make QM vs buying it, pea illy when yo yea perfectionist with 1 hand. Lol!!!! but when face with certain circumstances by having no choice do to budget issues I make it. If I made the extra cash I would just buy the stuff. Rolling up sum Kraft with dowel then using a little white glue(Elmer's) Works... American made Quick Match!!! I'm loving it!!
marks265 Posted October 26, 2014 Posted October 26, 2014 My wife and I even did some experimenting (not the kind some of the teenagers did in a trailer though) with QM, I'm surprised you both didn't get toasted from that too! 1
dagabu Posted October 26, 2014 Posted October 26, 2014 You are one classy guy Mark. I let your inability to make a sound Italian shell remind me of the ass you are and the ass you made for us. I love that 8" gun you blew out of the ground so much it's permanently mounted in my front yard. It reminds me and the rest of us here as well as the world how hateful and spiteful you are. Lucily, I'm here in California with 1000 other burn survivors learning how to bring hope to those severely harmed by fire. I will dedicate my efforts to helping others manage grief, pain, depression while you obsess yourself with creating pain for others just because you can. How about all you out there reading this exchange? Do you approve of this kind of behavior here on APC? 1
marks265 Posted October 26, 2014 Posted October 26, 2014 Too bad you bought some scrap iron in more of your stupidity. At least that didn't happen while looking at flash blowing up in my face. Try sending out some more smoke and mirrors to the unknowing. You are lying and feeling sorry for yourself so you should seek help as you are
Jakenbake Posted October 26, 2014 Posted October 26, 2014 You guys hang on one sec. I gotta go get more popcorn. brb!
