    Visco Fuse Machine

    well, best rotation speed is 130 RPM (a bit less or more , not a big deal). The disk witch one makes outer layer has to rotate at the speed not more 150rpm, the disk that makes inner layer has to rotate two times slower (it means 75RPM). I have built 3 visko machines. It allways worked. E.

    Visco Fuse Machine

    Hi folks, long time been on forum. Last week I again used my Visco Fuse Machine. I wind up aprox. 100m of it. Some observation- you can make as large as you want lower die hole. It doesnt affect winding quality of outer layer.

    whether it is true or not, but ive found an uncorfirmed info about fuse core composition. It says core mix must be made of 80/10/10. Those +5% KNO3 goes to burn threads. Once we are using traditional 75/15/10 mix, the oxigen balance is equal. But equal just for its self BP . BUT WE ARE FORGETTING thread layer!!! Its as well fuel as S or C!! So thread layer makes fuse with negative oxygen balance. The thread layer is using atmosphere oxygen in order to burn.So it makes burn proces slow if compare with BP burning. In order to make it burn instantly, same fast as BP, we must add excess of KNO3. Hmmm, this info made me raring to check it out. BTW, the info is referenced to WW2 time Bickford fuse core mixture. So I agree with Blafs idea to tread yarns with saltpetter. But how to do? Soaking and drying spools will make them rock hard. Shoud I soak it after? Erniz

    OK, I got your point, Ill try to explane, I investigated original chinise fuse.Original fuse has got turn step of 10:8cm (inner layer). Simply talking tread makes 10 revoliution in 8cm. Lower spool spindle deck must have always less spools becouse the angle of how it wraps/winds around inner thread must be steeper .Steeper winding angle of outher thread lay makes more reliable. Most reliable probably would be just with single one thread , but it isnt necesary. Since it wraps much thicker area and there are less threads ( 8 !) it must twist two times faster then upper deck (actualy lower disk does twist same speed as driving axle, upper disk rotates two times slower then driving axle). Problams to avoid: damp BP, if it is slightly damp it will not go in. It must be Sahara desert dry! BP must be meshed , particles not biger then 0.2-0.3 mm or it will jam it. First time try to make on upper and lower dies same 3 mm holes. It will give you 3 mm fuse. If you will be lucky to finde smaller/thinner threads ( they used to have some kind of "calibre" or size) then can try to make tinner fuse. Remember, if you wanna make two times thinner fuse then 3mm you gotta find two times tinner threads. You will not solve this by using less threads. This machyne is possible to make out from killed angle cutter gear head, or car windshield motor. I gues car junkyards can be found all around the world, so just go to nearest for VW Golf2 windshield motor. I will give a clear clue how to bild it , and it definatly work: find car vinshield motor with worm gear 1: 54 ratio and rip it of for worm gear, mount on it pulling spool with neck of 7.5 cm . Then mount 12 thread on upper disk cotton spools, on lower 8 spools. Make same size two pulleys for lower disk and driwng axle, and then two for upper ( one biger 2x for driven disk ). If you got any other worm gear kind, let say 1:30 ratio, then make pulling spool neck 3.75mm thick or make driven pulleys two times biger then they were. P.S. One more tip, as much as you wind more fuse on pulling spool, as much pulling speed gets faster.But thats OK. Just dont wind hundrets of meters of it. Once you got there 50m. Take it off an coat it with NC laquer. If gotta any Qs , go for it. Sorry for my English , this is not best writer competition, aint it? Ernis

    Observations on Visco fuse core mix: recently I gave trial with BP meal and crushed commercial sparcles powder. Results: 50/50 mixture gives speed 1cm/3s. Burning is slow, but relayable , no streaming sparcles, just very hot slag.

    Good day folks, I jus tried to edit my recent mesage but it said "you dont have the right..." neverless I was logged in. So I will corect my mistake with uploading pictures here: Edit: Pictures removed in request of poster. People seem to be reposting them on other boards and stating them to be their own work. T.

    Still in progress , probably 2 weeks. One teenager in my country did it acording my instructions. Removed dead links. T.

    New 2008.

    hello Blaf, I had some failures too, it is sad that it happened during New Yare selebration. I had bunch of rockets with exploding shels and stars. Since I was afraid to keep it at home (for fire safety), so kept them in trunck of my car. Humidity spoiled rocket motors, they dind go so well as it was during the test. But my fountains (tube 1 feet long) compensated with wengeance. They were made acording an old book recepy aut of BP and cast iron mixture. Since I used nozles in fountains , they were verry gushing and sparky. I dind do any cracker since my father in-low had axident, comercial cracker bursted in his palm.Neverless he was bleeding- lucky oldman anyway. He narrow -escaped, all fingers left ok, just his arm was tumid for a week .But he can blame just him self, he was trying to make bursting in the air.He used to ignit crackers and waith for a second then trew in the air. But he was lucky with one kind, but since he had some other kind he dind know delay time it led to the axident. But finaly he is ok., no residual scarfs or twingle.

    hello Guys, whats new? I have allmost done tutorial on Visco fuse machine, it is on You tube, under my name Erniz2. There are allready four instructions, only one left to upload. Take care!

    NC Application

    nice work out, ive made somthing like that. Ive made two pulleys down the bottom , but after first try they got jamed. Aftervords i had removed them at all. Just made roud like gruve, in shape of half cicle, it directs fuse down to NC and out.

    Well, I wouldn't mind, but it depends what country you are in, mail shipping restrictions , reimbursement way , etc.

    Thanks guys, Im working on that just found out reliable way of making pulleys Idea is to use circular cuter (is it corect in English?) wich one is used to cut nice holes in a board. You gotta get a plastic panel, cut out ,,plastic cakes,, cover with epoxy glue, string them together on the bolt wait until it sets. Then fix him up in to electro drill (with base support) and mashine just like in a lathe. Chisel is best to tool it. P.S. I forgot one sensitive point, plastic panel you are going to use has to be ecetone proof.
