I found a set of plans on the internet for a jet called the PJ15 by bruce simpson, but i noticed on the PDF file i have there is only one sheet but on the drawing it says "sheet 1 of 2" so i think i'm missing some infomation. Anyway down to the questions!
1) What is a good radius for the valve retainer? I know if the rad is to small then the valve will flex to much and fail premiturly.
2) How to design the petal valve and what thickness of spring steel to make it out of for this size of engine?
3)How to make an intake venturi without being able to spin it? (seems like it might be abit thin to turn)
Here is a link to the plans that i am using: http://www.zachmiers.com/pulsejetbook/plans/pj15.pdf
I thank anyone who helps in advance
