Because of the little time available i gambled and ordered the valves in 0.3mm stainless springsteel and hopefully it will work.
If someone think that it wont work or something like that it may still be possible to change the matterial if i call early tomorrow.

I realise that i need to order the matterial today if i am going make the deadline.
I can order 0,2-0,25-0,3-0,4 mm of stainless springsteel.
I was thinking 0.3mm thick and 38mm wide.

Thanks, i will try to do that,
My biggest concern for the moment is time because the race is in less then 3 weeks... (25-27 March)

This evening i made some parts for the fuel system , i am going to have two tubes with three nozzles on each one and not six nozzles on one tube. Any comments? Hi Erik, I suppose you have enough room to alter the clamp length or width for each valve in order to adjust frequency, eh? Yes i think i ca...

Yesterday i did some work on the venturi section and i think it did come out pretty good. Today i am going to start constructing the fuel system, i was thinking of using four 13.5gal/h and one 10gal/h oil-burner nozzles connected to two fuel pumps. With 2x 13.5gal nozzles on one pump and 2x 13.5gal ...

Thanks for you comments. :) What is your flow area ratio? I hope you can forgive me, but i have been away from pulse jets for a few years and haven't caught up with everything yet. What dimensions do you need? what is the valve cantilevered natural frequency? I don't have the valves yet, but the pie...

I was persuaded by Johansson and his team members to also build a jet powered kick and participate in the race. The valveless Lockwood engine i build a few years ago wasn't good enough and i always wanted to build a big valved pulse-jet so the decision to build a valved engine wasn't that hard. I st...

The plan i saw was from the patent.
But thanks for the new drawing.

Thanks for the help, i think that i try to make a own design an if i not manage to do soo i will use Andreas design. I wounder how critical the dimension of the U-bend is because one the patent drawing , the U-bend is formed as a cone but when i building my engine i will weld two 90 bend together so...

On most lockwood engines the u-bent is formed like a u but on this its two 90degre bent vith a pipe betwen, how would this afect the performance of the engine?

That vould be perfect, do you post them here or do you send them to my email?

I should need a plan on a Lookwood engine, but the most plans I have found so far costs money. And I... cant afford it. (If i had i woud gladly buy Bruce book) Therefor I am asking if someone on this forum might have an old plan laying on the floor, on the desk or on a harddrive that he would like t...
