Excursions into the past, Trebuchets

In an effort to show that I am a well-rounded individual, and to break any notions that I am slave to 'current' technologies, here is the trebuchet that my brother-in-law and I made a little while ago. For some history on these machines, check out www.trebuchet.com, or just Google the topic.

After a little research, I thought the best way to have fun would be to design it from scratch and build according to the plan. For kicks, here are some scanned shots of the 'plans'.

We used about 100 2" screws for the framing of the two 'A' frames that have the posts, for the long 10' piece that is the side supports and for the construction of the crossbeams. The three frames and the crossbeams are then put together using 4' bolts with nuts and washers. That way I can store it in an area that is only one foot wide and ten feet long.

I am sure the my physics is not optimal, but I during our first buildup (adding countersinks for the bolts and pounding them in the first time) we had it flipped over and it was still quite sturdy. The two six foot posts don't wiggle at all, we made sure all the supports were squared up before assembly and we didn't waste any cuts. Not wasting material is the key benefit in drawing up our plans.

The swinging arm and the basket we did free form so no plans, and this is only the basics. The weakest part right now is the sling, as the pouch is too small for most objects. So we need to sew a new larger pouch and redo the release. Other than that, we are doing great. It is made to be assembled or disassembled in about 10 minutes.

Enough with the fun and games, I have a small anti-spam module for Skejo.com that I need to finish.

haha That's awesome. It

haha That's awesome. It sooo makes me want to build one, too.

I've also considered buying a halberd just to carry when I walk through the park at night... ^_^
