now you're probably wondering what to do with all this wood. let's start by building the base. lay the two 4x4x2 pieces side-by-side and nail on a 2x4x7-1/4" horizontally against the 4x4s at opposite ends (looking at a side view). do this on both sides of the 4x4s.
you will want to place the last 2x4 pieces on the 4x4s at a point where when the side legs (2x4x32") are attached to the 4x4, the legs can also be nailed to the side of the 2x4. find this point (it is roughly at 12" from the top of the 4x4 to the center of the 2x4) and nail the 2x4s onto both sides of the 4x4s.
now looking at the connected 4x4s on the side without the 2x4s, position the 2x4x32" pieces so that their 30∞ cuts meet and form a straight vertical line at the center of the 4x4. find the height on the 4x4 (approx. 10" from the top of the 4x4 to the center of the 2x4 leg) that allows the far ends of the legs are level on the ground. check this on a flat surface (not the ground where you will finally place the base) and nail the legs on. repeat on the other side.
to build the pivot box, attach the 2x6 pieces so that the 11" pieces are opposite each other and 10" pieces are opposite each other. 
put the pivot box over the base with the 10" side being on the side with the legs. center (side to side) the box, then drill a hole (it should be slightly bigger than the diameter of your rod) through the box and the 4x4s above the legs where you will be putting the rod through.
now you can put the rod through the box and 4x4s. or you can consider putting pvc pipe through the hole first and then putting the steel rod though, this should prevent the rod from wearing into the wood (make modifications as necessary - drill a bigger hole, etc.). secure the rod on each end with washers and bolts.
with the base and pivot done, you can make the riding surface. simply lay the 2x6x12 pieces together and attach them by nailing the 1x4x11" pieces along what will be the underside of the riding surface. leave about a 2' gap in the center and space the three 1x4s evenly on both ends.
the last step is to nail this riding surface to the pivot box. if you just position the riding surface off center of the base & pivot box, the teeter totter will be weighted on the longer side which you can use as the approach side.
there are hazards associated with building, constructing and most importantly riding a teeter totter and singletracks.com is not responsible for any bodily harm or injury you may encounter should you choose to follow these directions for building your own and consequently riding it. |
