Plywood Challenge: Bike Polo Arena
I've found over two THOUSAND small 12" x 18" x 1" plywood pieces (hardwood, not OSB) . At $0.25 apiece, these are 1/10 the cost per square foot of Home Depot!
What is the CHEAPEST way you can think of to permanently join 8 pieces in a row, edge to edge? You have $0.50 per join. You must be able to lift the assembly and smile, confident and proud of its rigidity.
Already thought of:
Gluing (biscuit, tongue and grove, etc): Lots of work, might work with the right process.
Sandwiched between sheets (HDPE, HIPS, PC, etc): Expensive, >$1 per ft^2
Webbing, Jacob's Ladder style: Webbing ain't cheap
