I like using balance boards, because it’s scary for me to try things that have a good chance in ending in a UPD, because I frequently don’t land on my feet:( Those of you who have quicker reflexes, I think can benefit from occationally using one of these boards. Great on rainy days when I don’t feel like going out for a ride, or too physically tired for a ride.
Version one:
Supplies: 30”x18”x1” plywood, 18 “ 2x4, four 4” wood screws power drill.
-Mark both sides of the plywood, perpendicular to the 18” side down the middle w/ 15” on either side.
-Put wood glue on one side of the board, then place the 2x4 on it on end.
-Flip the board over and drive the screws through the plywood and 2x4 just to the side of the line, alternating sides. You should put one in each end first then the middle two.
Easier on hard surfaces, harder on soft, like carpet.
Option: fold up a large hand towel and place it under the 2x4 and you have to use for/aft balance as well.
Versions two and three:
Supplies: 30”x 12” x 1” board, two boards 30” x 4.5” (half of the diameter of the ball), two pieces 9”(diam of ball)x 2”, a large diameter PVC pipe 1-2 16’ths less than your ball diameter (you may need to insert some wood disc supports depending on your weight), eight 4” wood screws, four 2 – s.5” screws. All 1” plywood. Also large sports ball (soccer, basketball, valleyball should all work. I used a basket ball.) Depending on the size of your ball the width of the two 30” boards may vary. To find the radius of your ball divide the circumference by 3.14 and then divide again by two.
-Mark the 30 x 12 board on both sides w/ 10” in between lines.
-Glue one side along the lines
-Put on the 30x4.5 boards on end w/ the lines going down the middle of the boards, put 4 of the 4” screws in each of them from the other side. Start w/ either end again.
-Put glue the ends on the same side of the 30x12 the other two boards are on, then attatch one of the 9x2’s to each end w/ 2 of the shorter screws each.
Easiest to hardest: roller on carpet, roller on hardwood, slightly deflated ball on carpet, slightly deflated ball on hardwood, fully inflated ball on carpet, fully inflated ball on hardwood…
