My nieces 2nd Bday is coming up. I was going to build her a Seesaw and ironically my lil sister facebooks me a link to Seesaw plans.

Instead of just having a 5/8" bolts rubbing on wood, what would be the best way to create a bushing? I was thinking a piece of PVC cut to fit then bolt in the center.

I also plan on using 2x6 lumber instead so my brother inlaw and I can go on it. I could also just rung a 2x6 flat and a 2x4 perpendicular underneath, making it a little lighter. Then just radius/notch cutouts for legs at either end and a handle. My dad'd worry is it will be too heavy but its not really something that will get moved a lot.
 
find a tight fitting piece of metal pipe to sleeve the bolt, and grease it up with just about anything.

i'd sammich the pivot between some metal plates as well to prevent the studs from cracking out the middle, better yet put some pillow block bearings under them instead of the through hole.

+1. Metal sleeve.

drill out some notches on the bottom so you can change fulcrum position
make fulcrum with a piece of fence post pipe as the cross piece
just set the board on it
 
you really should just cut to the chase and build a catapult or trebuchet, that's what's going to happen anyway
 
Or, if you were the serious pimp daddy engineering type, you would build a four bar mechanism so that the see saw seats always stayed horizontal. :thumbup
 
^^^ Boom! May as well have some fun with it Dubs!
 
As someone that loves a good seesaw might I recommend that you put a nice padded seat on both ends along with a car tire in the ground with a 1/3rd of it sticking out to cushion the blow of landing hard. You are also going to want to weight the middle pretty hard to stop it from tipping to the side.
