Fantastic project! Definitely one of the more innovative uses for the Kreg Jig!  Great action shots as well!

Thank You. It was a challenging build at first but turned out to be a blast.

I gotta have one of these!

I want these plans - I have a whole neighborhood full of kids that would love this thing!

By the way I just used the Kreg to salvage a project where the supplied plans were grossly in error. $200.00 worth of oak would have been wasted.

Come on Chad, let your buddies have the dimensions here LOL. Did u use surgical tubing for the spring/elastics. I've use that before on a small trebuchet and it's great. Hope to hear back. Regards Pierre V

Thank you everyone for the compliments, I will get some rough measurements as soon as I get caught up with the spring lawn work. I didn't build it from plans just kinda shot from the hip on this one and it worked. Even a blind chicken gets a piece of corn once in awhile

thank you Mr. Chad, will look forward to it. Also tell us what you use as spring elastic. Tks

I just used bungee cord tie downs for the pull
