re: i need a quick reply about flameholders
can u tell the dimensions of the ramjet? like intake dia & length,exhaust dia and length.
i made a 2 inch dia ramjet and its less than 6 inches long
flameholder cross section should not be more than 30% of cc area

DONT make a ramjet's exhaust with ordinary cement ,it breaks under extreme heat conditions.

sheet steel?
from those air freshener cans . they are easy to bend and as i dont have any welding equipement i fixed the sides together with staple pins, the cc was also made from that steel and it was all fixed by staple pins.
not for very small cones

re: i need a quick reply about flameholders
ive been takin pic sof the project so far. i tried it without a nozzle and it worked great untiil the flameholder broke away. if i can secure it and get in a decent nozzle it looks like a success. btw i was out of gasoline and all other fuel, so it got it running off of paint thinner, its hard to light but it does burn (noxious fumes are a problem)

re: i need a quick reply about flameholders
For a steel flameholder for such a small jet, you could cut one from the nose end of an empty 8 or 12 gram CO2 cylinder. They are hiogh strength steel, can be cut and filed easily (they are only about 1 mm thick) and will weld beautifully, though you need a light touch.
Here's a little guide for cylinder cutting and/or lathe turning you can print out and mark up as needed.

re: i need a quick reply about flameholders
scroll up, but ill say them anyways.
8 inches long (have not made nozzle, can be either inside or outside depending...)
about 2 inches wide.
intake is formed but hole is only drilled to about 1/4 inch, can be made larger but best to leave it till after making nozle
it is an aerosol bottle, all steel. i have already heat tested it, it glows very nicely and i predict that it can take much more heat than gasoline and alcohol can make
