I might need help, I am watching a James Bond movie and there was a store scene with jars and skulls on the shelves. I guess it's pretty bad when you start to wonder if a skull could be made into a jam jar. It just crossed my mind seeing the colorful jars and skulls next to each other. I might need ...

Here's another interesting tale, my other brother was fishing at Fort Pickens National Park (an island fort with canons and where Geronimo was kept prisoner) anyway he was fishing with only one other person on this pier and he told the fellow it was looking rather iffy, with lightning and all, so my...

PS A buzz coil will last a very long time running constantly and it won't kill you like some other lethal designs. My brother worked at a company where a man stepped on an aluminum ladder that was laying on the floor over an extension cord and just fell dead on the spot. Electricity is something tha...

[quote="kristijan-k"]Hello,

Thank you all for the information.
You helped a lot.

I didn't see any fuel introduction method, you will have to work out a fuel flow metering jet/tube for the intake. But that shouldn't be too hard. Welcome to the world of exploration.

http://www.airpower.maxwell.af.mil/airchronicles/aureview/1984/jul-aug/roberds.html what i have found. looks pretty good from a skim over. Tom Kind of makes a pulsejet look primitive. And yet the speed of light is not fast enough for all our calculations. Mankind would prefer something even faster....

Shoot, I paid $30 for a brand new one meant for a gas stove, 'cause I was too impatient to find a friend with a dead stove in his garage; which would be the really cheap option, if he didn't make you haul the carcass off! I bought a buzz coil which is pretty good for making a hot spark but not enou...

Hey Chris,
How's the cute tiny Lockwood coming along? Are you having any propane mixture problems?
Mark

Sounds like you will be successful. One of my neighbors shoots off a ton of fireworks for the New Year and the 4th of July Independence Day and the guy on the other side is from Lebanon, so they're used to noise. ha ha Then behind me is a U. S. Navy Base fence and they have some crypto/code secret s...

Spark source: http://sales.goldmine-elec.com/prodinfo.asp?prodid=7049 Schematics: http://www.repairfaq.org/sam/samschem.htm (search for "kool") That's the cheapest ignition I have seen. I wonder if it would get hot if you ran it constantly rather than the intermittent firing it was made for? I wond...

Try using portland cement. Eeeagh! Cement pulsejets? Given the tendency cement has to explode and throw off nasty chips under extreme heating, I'd just say this: Be sure to wear goggles. I would try this myself but my goddamn well is all froze up again so I have no running water. Solution - I'm gon...

If the center tube is left open at the exhaust end, you might could push some sausages up inside and cook them if you are going to run it on propane.

Nobody seems to be addressing the heat issue or the furnace you are going to subject the inner tube to. Maybe instead of putting it in the center, one could just put it to one side, and use the heat to weld it to the adjacent wall. It might be fun to make the inside tube the fuel tank, if it got too...

OK then, how about molding an engine out of castable ceramic loaded with stainless steel wool???? Hmmmmm! Faaaaaascinating. http://www.use-enco.com/CGI/INPDFF?PMPAGE=709 I have been mulling around with using foil for a few years now, just to see if would work or bind or fuse with the right ingredie...

I like the powder coating.

I was just rummaging through any hits on pulsejet heaters and I came across this crumb. http://www.hvacware.com/user-cgi/hvaconfig.pl?read=1358
