How Would I Make a Firing Mechanism for a Catapult?
So I am trying to do this instructable here >>https://www.instructables.com/id/How-To-Build-A-Catapult/
and the author doesn't seem to be answering questions anymore. I am wondering if anyone else knows what to do with the firing mechanism if using fibreglass pipe. Because if a hook is screwed in it, it seems like it would probably break out of it under the strain. Anyone have any ideas what i could do for the firing mechanism? Thanks!
