This is a seesaw and track (channel) for Brio type trains.
Full instructions at:
The train will be modified and this will become the "Froggy Express" at Froggy World--hopefully to be shown at the 2013 San Mateo Maker Faire.
"railroad track a" is the key piece. For shorter pieces, cut part of it off
The current pieces allow a 12.5 inch diameter circle. For a larger radius, take "railroad track a" and do "15 degree cuts" on both ends--the longer the top of the track, the larger the radius.
You can make any angle you wish by changing the cut on the ends.
