[/img]These are the plans we have edited from elsewhere and created this prototype.
Right now we are having trouble with our Blow gun assembly that is supposed to act as our trigger for releasing pressurized fuel into the gun and out the barrel. The blow gun we bought is pressure rated to 90 PSI but is leaking at only 80. When we first assembled it, it would hold back all the pressure of the tank and not release pressure until we pushed the trigger. However, now it is slowly leaking without pushing the trigger.
I have posted about our flamethrower before and have gotten great feedback as well as extra precautionary parts and things to watch for and how to be as safe as possible.
Also, many people have strongly advised that we use an inert gas to pressurize our tank so we don't explode. However, we are worried about the cost effectiveness of using anything else since we currently just use an air compressor to pressurize it now.
Some of you have even said not to use propane, which was our second choice, and to use CO2 instead. If we were to use propane, how would we get the propane into the PVC tank and pressurize it? What parts would we need?
Actually, more puzzling to us would be how we would use CO2 to pressurize it...? How would we get CO2 into the tank...?
Currently, we have a schrader / air valve that we got at an auto store and threaded and welded into the PVC tank. This was easy and we can just use an air compressor and fill it like we would a tire.
SO, we have the fuel tank assembled and the gun almost assembled but we haven't housed the whole gun in PVC yet since it is not quite ready and is leaking...
In addition, we used the proper pvc weld, pulmbers solder and weld, then in addition went over EVERYTHING with JB weld. It works miracles. haha
Well, thanks for looking at our project in the making, and we appreciate all constructive feedback.
Thanks.
