murderskill Posted April 29, 2006 Posted April 29, 2006 I have read somewhere in the past that if you use hot glue over the fuse to make a seal that it somehow screws up the powder core. I am going to do a test on this with a tube, paper endplug and fuse inserted into the endplug and hot glue covering the endplug. I placed a little bit of BP in it so I know if it actually works. Lets see what happens.
murderskill Posted April 29, 2006 Author Posted April 29, 2006 WOW it worked perfect! It didnt effect the core of the fuse at all. Its like it didnt even melt the glue. It burnt a perfect circle where the fuse was and ignited the BP. I wonder if it will work with aerial shells like that?
murderskill Posted April 29, 2006 Author Posted April 29, 2006 Is it low-temp or high-temp melting glue? The glue is High-Temp. Maybe that explains why. But you would think that 3/32 visco would burn really hot?
ewest Posted April 29, 2006 Posted April 29, 2006 I use that exact process for my aerial salutes out of cakes and I've never had a problem. I use regular American or Chinese 1/8" visco, insert the plug into the tube about 1/4"-1/2" depending on how long you want a delay, insert the visco and fill the cavity with low temp hot glue. You could probably use the high temp glue also, I just never have. Seeing as how the salute isn't filled at this stage it couldn't hurt to try. I've done it before with white Elmer’s glue when I ran out of hot glue but it takes a lot longer to dry and it really shrinks, but still works great. United nuclear has a tutorial on this same topic, but instead of Elmer's glue, just use the low temp hot gunhttp://unitednuclear.com/aerialmortar.htm
Frozentech Posted April 29, 2006 Posted April 29, 2006 I have read somewhere in the past that if you use hot glue over the fuse to make a seal that it somehow screws up the powder core.

Lets see what happens. If you are using 1/4" time fuse on a shell, you actually want the glue hot enough to 'wet' the outer layer. I don't really use visco for time fuse in shells other than inserts, so I can't tell you the effect there.
Douchermann Posted April 29, 2006 Posted April 29, 2006 1/16" chinesse visco is the one that it can't burn through. The fuse will stop at the glue.
shadopyro Posted April 29, 2006 Posted April 29, 2006 I've had that problem using 1/16 in chinese visco, in small salutes etc, where the fuse just stops burning when it reaches the endplug. All i do is wrap the glue in a layer of clear sellotape, and then it works perfectly.
kwstag Posted April 29, 2006 Posted April 29, 2006 I've had the problem using epoxy.. For some reason the fuse stops right where the glue touches it..
dragonman586 Posted April 30, 2006 Posted April 30, 2006 I have no Idea what is worng with your 1/16" fuse but it has always worked for me.
murderskill Posted April 30, 2006 Author Posted April 30, 2006 The method I tested was with high-temp melt glue and it worked fine. The method stated in an earlier post with the elmers glue is the way ive always done it. I just put a heaping mound of glue because it does shrink. I just don't go outside of the ID. I do it mid day and let it sit while I sleep to let it dry all the way. The fuse that didnt work for me with the hot glue is uncoated fuse. Stops at the glue.
Pyrohawk Posted April 30, 2006 Posted April 30, 2006 It always works on 1/16 Chginese for me. That is actually the only kind of fuse I own.... I have no regular visco!! My only fuse is Chinese Viso and I use it for everything....
Mumbles Posted April 30, 2006 Posted April 30, 2006 Problems with hot glue come into play more with uncoated fuse. It can seep into the fuel, and effectivly form a fireblock, or cause it to smoulder or something proving inaccurate and potentially dangerous delay. I've also heard of people having problems with cheap timefuse. I could melt the less than adequate asphault layer causing leaching into the actual fuel.
joker5 Posted May 1, 2006 Posted May 1, 2006 if you have problems with the glue seeping into the core you can put a layer or two of masking tape around the fuse where you will glue it. thats what i do also to adjust the delay time in an aerial shell. plus i prime the visco delay fuse with ping pong ball primer to ensure ignition.
Caleb51 Posted May 1, 2006 Posted May 1, 2006 Okay boys, game time. Whoever started this thread (I forgot who, sorry) take a piece of whatever waterproof visco you have. Take a 1-2 inch piece, hold it with pliers, and light it. Look closely at what is happening. Then take another piece of the same size, hold it with the pliers, light it, and quickly completely submerge it in a swimming pool or bucket of water or whatever you have. Notice what happens (Something totally different then the dry test) And then post your results. As fas as I know, this is what happens when you put glue over it too, or tape, or basically, anything that doesn't wana burn.
