.....The inside diameter (If I'm not mistaken) of 5/16" Steel BrakeLine is 1/4" and the O.D. of 1/4" Steel BrakeLine is (of course) 1/4" . - If you were to sleeve the 1/4" BrakeLine, with 5/16" Brakeline...
.....While you're trying to start your newly-fabricated pulse jet, this sleeve could be slowly pulled back until your engine began to "growl". Further adjustment could be made once the engine was running, until you found an optimal setting...
.....As the 5/16" Steel BrakeLine is pulled back, more holes are exposed...
.....With a large amount of holes exposed, the injector could possibly be used to fuel engines as large as a Lockwood-Hiller...
.....With all the pictures shown, the only thing missing is a piece of 5/16" RUBBER fuel line and some hose clamps, to seal the other end of the line...

Re: Idea for Adjustable Fuel Injector
That looks like a pretty cool idea. I might have to try it out on the big lockwood. Any ideas on how many holes you think to run a big lockwood?

I found a pdf file on the fuel rail for a large pulsejet, on this topic: Lockwood Helpkeith mcconnell wrote:That looks like a pretty cool idea. I might have to try it out on the big lockwood. Any ideas on how many holes you think to run a big lockwood?

16 holes (8 sets of 2; holes were drilled straight-thru) @ 0.078" each (#47 drill bit) have a total surface area of 0.076+"
12 holes (6 sets of 2; holes drilled straight-thru) @ 0.059" each (#53 drill bit ) have a total surface area of 0.032+"
Total surface area of 0.109"
With a No. 65 drill bit (as I had suggested) , you would need 57 sets of 2 (or 114 holes) - - - My drawing showed each row as having 12 holes each (each hole being 30 degrees apart).
You would need to expose 9 rows of holes and half of the 10th row.
... My best guesstimate, as I really have no clue.
