Re: Liquid fueling.
My large pulse-jet runs on liquid propane and runs pretty stable once the preheater coil has warmed up. I have the throttle located just before the pre-heat/evaporater coil. Putting in a pre expander defies the purpose of the evaporator, It will freeze and you'll end up trying to run your engine on ...

If you'd bend your fuel line (stainless) around the hottest part of your engine a couple of times (6-7) you can run liquid propane, by turning your bottle upside down, to the "evaporater". Start with the throttle way down till it heats up.... You can run it till it flames out and your bottle wont fr...

The fuelsystem in the "Kolibri", the dutch ramjet powered helicopter, had no fuel pump; it was using centrifugal force to force its fuel into the ramjets.......see if this works.. http://portal.omroep.nl/mplayer?mpstream=rmbb&mpurl=http://cgi.omroep.nl/cgi-bin/streams?/ibg/sn210015-bb.rm&titel=DE%20...

re: New ramjet experiments
Looks to me that your flameholder is bending by the force of the blower. Remember it is very hot during a run. Perhaps try a more heat resistent steel as well as different shapes. Nice work!

re: Metal thickness and other questions...
I have cut my curves and circles with a small handheld anglegrinder (flex in germany). Use a 1mm blade and cut a leading groove on your plate (just on the outside of your markings). Basically a cut of 0.2mm iI guess. After that keep cutting the same groove deeper till you're through. A little cleanu...

re: LHPJ
The nozzle is a modified oilburner nozzle. Very commen in central heating systems. I cut a slot in the top of the nozzle (across) with a small saw. The nozzle is steel. Then after inserting a feeler gage in the slot, tapped the cut evenly with a hammer. Blowing smoke through it showed the uneven gap...
