pirate ship teeter totter

I have 3 Grandson's that love to be pirates so I decided to make them a pirate ship teeter totter. After searching the Web for plans and finding nothing I was looking for I decided to just go for it and see what I could come up with. This pirate ship is heavy duty. I use 2x8's, 2x10's and 2x12's for the frame and seats and 1x10's and 1x12's for the inside foot platform. It's 5ft long, 3ft wide and 3ft high. I had to put some stop blocks on it or it would of been a catapult instead of a teeter totter. (I know this because I climbed on and took it for a ride) Everything is connected using pocket holes and pocket hole screws (Thanks to my Kreg jig) I added a pole up the center and added a pirates flag and puts some swords on the sides. The kids sure have fun on it and so do I.
