hello from texas here's my video http://videos.streetfire.net/video/1923 ... a3463a.htm i built from a scrap sheet metal duct that is about 26 gauge steel and rusted.... cant figure out why it doesnt melt run after run ..... gonna build a drag cart with twin engines heres my other car http://videos.streetfire.net/video/1CE9 ... B6A8DF.htm

i have no plans.... just made it from calculations scaling from what people use to make the 55 lb lockwood..... i fabricated all in two days, just a couple of hours or less.... did all for less than ten dollars... just cuz i bought some sheet metal snip.... planning two 38lb for a drag cart... or 190 lb twins... takes me about two hours to make em..... i triangulated the metal funnels all by hand ... i use no spark plug to start them... just lite the flame at super low psi... raise the pressure till it gurgles... huff some air from the leaf blower a couple o f times..... then continous sustaining flame till crank fuel up till explodes and continue to throttle... i am willing to help anyone who asks.... steve

I like the cut of your jib Steve! What did you use for the 180 degree bend and what size is it?

[mrsteve79915]

the mandrel bend is a 1 3/4 in mild steel 14 gauge though aluminized pipe..... incidently..... the only piece i once bought and had laying around

here a pic when off

The aluminized is better than just mild steel, at super high temps it will keep the steel underneath from absorbing O2 and flaking. It might make a really nasty surface but shouldnt flake at all.

Whats the thrust like? about 20 lbs?

from the math in my head... 38 pounds give or take... i used a 35 pound weight to hold it down.......... was pushing through it on a day run when i was showing my nephews..... funny the the funnel on the intake was formed just using a pair of pliers.... the exhaust long funnel was made by pressing around a 2 1/4 pipe to form the contour..... i gently spot filleted the entire pipe simulating a tig weld..... paper thin combustion camber holds well..... weird...
