Re: New guy getting started
Yeah, I've got a similar fitting. If you're using a store bought hose assembly, you'll get a really small hole that you can't drill out:
So it's worth going to the RV supply for this type that Grim shows.

Hi Clay,
Cut a 3 inch length off a stout wire coat hanger ...and then hose clip that to
the intake...then you can use a smaller hose clip to attach your fuel line/stinger.
A simple way of doing it and easily adjustable - later on when you have it
all worked out and running you can make a more permanent fixture etc.
I even clamp my air line as well - just saves you from running out of
hands etc and doing a one armed wallpaper hanger impression.
Hope that helps.

Yeeha! She lives! ...and my neighbor told me so on Facebook. It took some doing, but between the new fuel line position (roughly 3/4" in the intake) and the needle valve it just took some air/fuel balancing. I got her going nice, as you can see from the video. I then "choked it out"- I raised the fuel until it quit so I could see how much it will take.
I drilled out the tank fitting already- I figured there was not enough flow with the fitting I had, and I could always turn it down.
Success rocks. Time to practice starting and running it and show some friends...

Congratulations, sir! As you can see, there are only two basic factors to valveless pulsejet success:
- Lots of patience
- Getting everything right
Ha.
That first time you get one to roar to life is something you'll never forget. Great stuff, man!

Re: New guy getting started
Thanks guys- it's very exciting! I was pretty stoked when I went in. I also need to make some mods that a couple of you pointed out- adding a wire for fuel line adjustment is brilliant- I also need to weld on some legs to give it a little clearance. The C clamp worked, but I need to make it a little more portable and raise it up a little higher and add some heat shielding. I might make a bracket that snaps in a brake rotor (it's what I have sitting around)- that makes it portable yet solid.
This thing is sweet. Once again, thanks a ton for all your help!

Here's my favorite way to do an adjustable fuel stinger setup. The air tube is welded in place, and acts as a base for the fuel tube. Three tiny hose clamps secure the fuel pipe to the air tube and allow adjustment in and out of the intake. This is all mild steel (brake line tubing), not stainless. Of course, this takes patient, rather delicate welding. Also, I have been told (though I have no way of verifying it), that electric welding methods won't work successfully on brake line tubing.

Re: New guy getting started
That's great! It feels good when you get your first motor running.
Now that learning curve is out of the way the world of pulse jets is yours for the taking!!!
Good work, congratulations and I hope the neighbours like it?

Re: New guy getting started
Tonight I built a cradle for the engine to sit in with a wire frame under the combustion chamber for a tinfoil reflector to sit in. I started and ran it twice. I also bulit an easily adjustable fuel line pipe much like Larry's- thanks for the idea! I also spent much more time noting settings to get her started.
Now I just need to stop running it after 9. The neighbors haven't said anything, but I'm sure they're thinking it!
