Mortar Help

Unread postAuthor: SpudsMcGee » Sun Jan 11, 2009 6:12 pm

I just build a cool medium sized spud gun, and I was really happy with the results that I've been thinking about making a mortar launcher to shoot a mini dodge ball, I saw at a sporting goods store. But I don't really have that much money and I don't know how big of a pipe I would need. Can you help me...

He didn't ask for plans. He asked what size pipe he would need for this mini-dodgeball he's found.

@SpudsMcGee,

I have no idea how big or small this dodgeball is. You're going to have to measure it yourself and get back to us, then we can recommend a pipe size for you.

This might help identifying what size and schedule pipe would be required for the dodgeball:

I'd go with a burst disk design. Just search burst disk. It's definitely the cheapest and safest way to go.
