Thinking Re: Looking for JetX Fuse

Post  Ken Cook on Fri Mar 15, 2019 3:25 pm

This is very difficult to source, the next problem is that it's probably bad. The fuse isn't like rocket fuse, it's almost like a coated wire. When flexed even slightly it either breaks or crumbles.This is true even when it's been stored in the small tins it came in. There's Jetex and also Jet-X. The fuel pellets from Jet-X are not compatible with Jetex but the fuse might work. Jet-X engines were sold as Powermax units. Keep in mind though that all Jetex pellets are not compatible with all of their engines. Red Dot Jetex pellets only work in the all steel Jetex-50. Jetex also made a Psst .50 and some all aluminum cased engines were only their latest fuel pellets worked in, if you try to use Red Dot pellets in them, they can melt and even possibly burst. Bob Davis from Davis Diesel was responsible for the Jet-X Powermax fuel and engines. He sold it in the 90's, it might be worth finding out where the stuff went. If you do find fuse, keep in mind the pellets are coated in varnish, the bottom and top need to be sanded or scraped. You sand them and save the dust which you pour back in around the coiled fuse, this assists lighting it off. In addition, using a lighter, heat the back half of the engine where the fuse enters so that when the fuse burns, it doesn't get quenched out at the exit point of the engine.

That fuse will probably not fit the Jetex engine. The fuse diameter of Jetex is smaller than a model pin. Any alteration to the hole and the Jetex won't work as intended. When the Jetex lights off, you can't have any residue left in the orifice. When the Jetex wick has been ignited, the wire is still left in place in which you wet the tip of your fingers and quickly yank it out.

Jason, I thought of that myself. The problem is the diameter of the hole and the electric ignitors would have their leads touching one another shorting against the metal case. This has been a long ongoing problem with Jetex users the wick and fuel. There was a fellow who made a special ignitor which looked similar to a hand held barb-q lighter. You might be able to find some info here http://archivesite.jetex.org/ The ignitor I mentioned is for Rapier engines which were Czechoslovakian, I believe there were those that adapted this for Jetex use. Rapier engines were great, I had a few but they were difficult to source. No longer produced either. Currently, I have two Jetex models ready to go. These engines are not easy to light off. I have expelled about 6" of wick trying to get it to ignite. My dad was the one who mentioned the fuse quenching at the exit. This is exactly what happened to my attempt.

They make this super small fiberglass tube insulation. I use this on my bead thermistors on the 3D printer heads to insulate the leads electrically.

Not cheap either.

Just for clarification, the hole that the fuse goes into is about .035". The next hurdle would be the screen it passes through in front of the pellet.  The Powermax Jet-X fuse is much more reliable if it works in the Jetex. I believe it does. Ebay seems to be the best source for supplies.

Would 1mm cannon fuse work?

Aside from alibaba.com and Made-in-China.com where you need to order a pallet of the stuff, this appears to be the only site showing it available. I would try calling their phone # at the bottom of the page first.

I have a few feet of bigger cannon fuse...no wire


Sneaking in a single strand of copper or wire tie soft steel should be doable... ....but still a PITA at that small diameter

I also suspect you could roll the 1mm stuff between two flat plates and make is slightly thinner

That is neat. I have read of these engines before, but never seen one, let alone see one in action. Thanks for sharing.
