How do I construct a Pneumatic Cylinder?
I would like to know if anyone has made a Pneumatic cylinder out of an old Coleman Lantern green gas tank. Or What about making out of PVC? I'm making a halloween prop that it using a door closure as a piston. It needs about 60 to 70 pounds of pressure per use and will be fired about 10 times. It uses up about 5 pds of pressure on each firing. Any ideas on making a cheap regulator for this would be helpful too. The prop will be outside in the woods for a haunted trail. So having it self contained would be nice. I didn't want to run an air hose 150' to make it operate. Thanks.
