1st post here. I've been telling myself I would build a hybrid cannon since I first built a spudgun over 10 years ago.
I've started working on the design on CAD and should have something to work with in the next few weeks (when time allows)
There seems to be quite a lot of contradicting information on how to correctly fuel a hybrid cannon. I have read all the info and hopefully I've understood it correctly as I've created a table of the the pressures required for fueling - I wanted to have the table coded within my post but I didn't have any luck with getting that to work so I've uploaded an image.
Hopefully it is correct and makes sense to all who use it.
I'll keep it updated with other fuel types as I find out more.
Harness the power of precision mixtures of pressurized flammable vapor. Safety first! These are advanced potato guns - not for the beginner.
