Please step in and see one of the newest areas of our site diycatapult.com focused on Spud Guns research and content. No, you are not crazy, our Spud Guns area is still a bit lacking in findings. Perhaps this area will get more attention once we complete the potato cannon and potato gun menu items. Why not send us a quick note covering how you got into instructions how to make a bow arrow so we can get inspiration to finish this Spud Guns content. The diycatapult.com team is currently finishing up the make homemade explosives publication and this part is next in line. We expect that you will find sections Spud Guns, how to make a tennis ball launcher, and potato gun to be built out with good synergies in place. For more Spud Guns help, you will need to stop back to diycatapult.com shortly for updates.
