Would you like to build a drawbridge?

How about an archway?

With a set of BRIDGE BEAMS and your imagination you can build almost anything.

 Here's a cable-stayed bridge- like the new Tillikum Crossing

 .

The bricks are  the counter-weights

This  "excavator" has a pivoting arm with a scoop at the end

You could build a crane that could raise small loads.

The BRIDGE BEAMS are lengths of alder (3/4" thick and 1 1/2" wide) with holes drilled every 4".

You can stack and arrange them however you like, and use 3/8" dowels to connect them together.

Once you add lengths of string, a lazy susan, pulleys, wheels and a windlass, the sky's the limit.

You can build pretty much anything.
 
This building has an elevator operated by a windlass.

swinging door- (the 2 small 1-hole pieces that pivot on a dowel)
