So this winter I tried to fulfill my childhood dream of having a backyard rink. I got myself very excited to do this, built the rink, built dasher boards, ordered my liner, filled my rink, and then disaster struck.
My wife just called me at work to tell me that the board collapsed.
I used the OSB boards and wooden stakes with triangle brackets around the deep corner, but it turns out my 12" pitch put too much weight on the boards. Next year I will try again, and without pinching pennies. I advise against OSB w/ wood stakes for a larger pitch. I'll be rebuilding next year with 2x12s. In fact, I'm going to start stocking up on them now.
