For Estes type paper tubes, I use a small miter box and an X-acto razor saw. Need to do a little touch up with 220 sandpaper afterwards and then you’re good to go.Welcome on board.Warren

The only cannon I’ve ever had was a PVC potato gun I built, but that used either White Rain hair spray or propane. My cousins had a carbide cannon that made quite a noise as I recall, but I was…   Read more»

I didn’t know about this until Saturday morning and was very glad to see in the chain of emails that I found in my box that you folks, Art, Conway and everyone else were uninjured. All my best to everyone…   Read more»
