Dadgum - that organ would be something to see! I bet it sounded like the ancient titans themselves were making music.

Re: Please put your "I am new and need help" question here.
Heh heh. Thanks I will experiment with incorporating all of these suggestions as I narrow down the solution. I saw those step up electronics as I was looking for a solution. Pretty neat. 50,000 volts... Overkill is always worth major overkill! Has anyone died from home made pulse jet detonation? Jus...

Re: Please put your "I am new and need help" question here.
yes - I got a AA battery powered one. It wouldn't work except to spark me until I figured out you have to ground any un-used terminals. So not I have grounds wires, and I feel like the spark is quite significant. I have the plug gapped such that I can see quite a nice long blue spark when I look int...

10-4. I’m also going to eliminate spark as a variable by using a sparkler.

Re: Please put your "I am new and need help" question here.
Mike, I have now copied your fuel stinger using 1/16 ID copper tubing, which is about 1/8 OD. I narrowed the orifice by putting a small pin-vise drill in the hole and squeezing the tube end around the drill with pliers. 1/16 would be about 1.6mm, I think its now a little under 1 mm. The copper tube ...

Re: Please put your "I am new and need help" question here.
Thanks! I remember reading the tutorial because I recognize the description of playing with the positioning of the fuel injector and the growling vs gravelly noise. I appreciate that you clearly talk about low fuel pressure because I have a colleague who is telling me I should basically dump a ton o...

Re: Please put your "I am new and need help" question here.
Mike, Yep I beveled the intake opening and at the CC, and the exhaust tube at the CC and the exit. I rounded them using files and then finished with sand paper drums on an air tool. Re the tubing I have surplus copper tubing that is 3/16 OD. I could add that into the final end of the tube using a co...

Re: Please put your "I am new and need help" question here.
Sure, Mike. I always take a little time regaining skills for uploading pics, so hopefully this works first time. If not I'll jump back in and edit it. First is pic of the Fuel Tank connection hose with the gas ball valve spliced in. This is a 350 PSI rated propane gas hose w a 3/8" ID, held onto hos...

Verifying No Weld build and Q about fuel amount
Very informative forum and I've read as much as possible. For simple engine, there's a lot to soak in. I built the No-Weld plumbing parts pulsejet Mike Everman provided plans for. Having difficulty getting it to stop spitting orange flames and make small purring, gurgling noises. I'd like to ask any...
