Step 8 Attaching the Legs

With the legs made we now need to attach them. Use the height of the pump and length of tubing from the last step to determine how deep into the ball the legs should go. Mark this on the leg. Then determine the diameter of the leg and select a drill bit of the appropriate diameter. Attach a drill bit stop to the bit at a distance from the tip equal to the depth you want to drill. (e.g. if you want the leg 1 1/4" deep into the ball set the stop at 1 1/4" on the bit).

With your drill set up you now need to mark where you want the legs to go. I chose a trangle pattern around the central tubing hole. Choose whatever configuration is most stable for your project. Once your positions are marked drill the holes. Don't push to hard or the bit stop might slip and you'll go a little too deep. Once your holes are drilled clean all the dust and crap out and test fit the legs. You want to make sure they are a tight fit and go deep enough.

After you dry fit the legs mix up some epoxy. Slather it onto the portion of the leg destined to be embedded in the ball and insert it in the hole. Have some paper towels or scrap cardboard near by so you can clean off any excess that may dribble from the hole (or you can just sand the excess off later). Repeat this process for the other legs. Now give the epoxy about a day to fully cure. Then stand it up and see if it falls over.
