How to Create your own Wobble Board
overview | wobble boards / balance disks | pipes | slant board
Creating the wobble boards (balance disks) presented the most difficult challenge of all of the ProBodx equipment. After some planning though, I think I've found a relatively easy wobble board creation solution:
First, head to the lumber section of Home Depot. There is typically a small area devoted to oddly sized and oddly shaped MDF (medium density fiber-board). I found 12" diameter, 3/4" thick, circular MDF disks that work perfectly for the surface of the wobble boards. Purchase two of them to make one wobble board for each foot. Home Depot carries varying diameters, so you can choose the size that works best for you.
Next, you need something on which this circular board can wobble (or else it wouldn't be a wobble board). This requires a few things: a PVC pipe end cap, some small-ish wood screws, some Liquid Nails (or other strong adhesive), and some spare 3/4" thick plywood. If you notice the picutre in the first column, four rows down, you can see what to do with the plywood: You cut circles out of the plywood such that they fit snugly within the PVC end caps. The picture directly above that one shows how I cut the circle — I found a cup that fit nicely inside of the PVC and used the circumference of its lip to draw a cricle. A jigsaw will then allow you to cut the circle out properly.
You then attach each of these small circles to the middle of each of the 12" diameter MDF wobble board tops. I did this with a singular counter-sunk screw, from the top of the circular MDF wobble board (where your feet go), through to the smaller circle. To counter-sink the screw, you can use a drill bit that is larger than the head of the screw, and drill into the top of the wobble board just slightly. I also used some Liquid Nails between the smaller circle and the top of the wobble board to help secure the connection between the two (you don't want the smaller circle rotating at all).
Now, you should have a wobble board without the wobble. To create the exciting wobble action, you can now simply slide the PVC end cap over the smaller circle (after applying some Liquid Nails to its circumference), and secure it by using some small screws — screw through the PVC end cap horizontally into the wobble board. If you look at the picture in the second column on the fourth row, you can see two screws going into the PVC end cap. There is a third screw on the other side of the wobble board. You can also see the excess Liquid Nails where the PVC meets the top of the wobble board.
Finally, 3M makes some non-slip, grit paper with adhesive on one side of it. This stuff is shown in the last two pictures of the collection below. I'm not exactly sure where in Home Depot I found this stuff, but you can just ask for some non-slip/non-skid adhesive paper, and they'll know what you're talking about.
So after all that, I had two complete wobble boards for around $8 or so. If you need any more thelp creating your very own wobble boards, please feel free to email me.
