yes! another excuse to bust out my favorite stationary - green engineering graph paper. the plan was to build a 12 foot long teeter-totter with an approach angle of 20-22°. the materials needed are as follows…
for the plank (rideable area):
- 2 - 2×6x12
- 6 - 1×4x11″
for the base:
- 2 - 4×4x2
- 6 - 2×4x7-1/4″
- 4 - 2×4x32″ (30¬? cuts on both ends)
- 2 - 2×4x30″
- 2 - 2×4x55.5″ (optional supports)
for the pivot box:
- 2 - 2×6x11″
- 2 - 2×6x11″ (can be slightly shorter in length)
and to hold it all together:
- 1 - 3/4″ steel rod (min length of 14″)
