Walls and liners questions and some input ...

    I was wondering what most of you use for your liners. Also, how do you prevent it from being ruined by skates or sticks. Here's what I thought of doing for next winter, and I'd like some thoughts.

• I'd like to build the boards and forms just the way we see them designed elsewhere on this site. However, I'd like to set up the bottom edge of the boards to three inches off of bottom of the rink. That way I'd have the a little three-inch gap and not worry about the bottom of the boards cutting into the liner.
• Several inches higher, I'd drill a 3/8-inch hole through the boards and the brackets to hold up the boards.
  I'd then take a 3/4 stainless steel carriage bolt to go through the boards and the grommet on the liner, holding the liner up and preventing the the bottom of the boards from cutting in.
• I'd fill the rink up to the edge of the boards.
• I'd also put some 1x4 boards along the bottom of the boards, painting them yellow to give the same look as the bottom of the rink.

  The rink will probably be just 25 x 45 this year. But since my sons will be seven and eight next winter, I'm not concerned. Once we get into a bigger home with a bigger yard, I'll go bigger. The rink will be smaller than what I want for my size, but it still be nice.

   Thanks in advance for any input you may have.
