Re: I got some questions.
Since posting i believe i have figured out my issues. I noticed that if I leave the gun sit for roughly a minute before firing it goes off reliably. I increased the chamber volume aswell. I am in the process of creating a "venturi" fuel mixing system to mix the gasses as the chamber is filled. With...

Re: Golf Ball Cannon - Suggestions Please!
To install, you could blutack a piece of padded tape (non-sticky side) on a piece of 1x1 lumber, slide it down the barrel to the right spot, then roll the lumber over so the tape stick at just the right spot... rolling it out again might be a problem though if you overfuel... https://www.uline.com/P...

In my cannon I just used a piece of double sided tape that holds the ball firmly, but I have a bolt action... viewtopic.php?f=27&t=27104

Re: Using Burnt Latke's fuel tool
Correct, meter pipe volume needs to be approximate, with the fine tuning of moles of propane to moles of oxygen being done by adjusting pressure in the pipe. If you find that you can't get the right load, you can change the length of a nipple on the pipe to add/remove 1/2"+, much as Latke said here....

Re: Using Burnt Latke's fuel tool
I think I came to the same conclusion about 10 years ago... I assume you found this... it gives a good clue, but I still wasn't sure... I think he means volume of the propane (meter) is 4% and the volume of the air (chamber) is 100% The pressure regulator proved to be the key element. A mid range ba...

Re: Multiple ignition points?
http://www.burntlatke.com/strip.html He is right about the veracity of the data, since his standard deviation from 10 shots is bonkers high due to the russet factor, but his data does bear out what we all know instinctively to be true, more sparks (well distributed down the chamber) = more higher i...

Re: Propane failing to ignite reliably.
Easiest way to understand C:B ratio is that if the barrel is too short, the projectile is still accelerating when it leaves the barrel (sub optimal), and if the barrel is too long, NEGATIVE pressure behind the projectile will slow it down before it exits the barrel ( if your barrel is very long, and...
