Step 5: Drill the Holes
Start by flipping the set up over, so that you will drill from the bottom. also, be sure to that the side you cut will be the side on the ground, so that the trainer sits level.
drill 2 holes through the short one, and half way into the long one. If your bit is to short to go half way into the long one, just drill enough through to leave a mark on the long one. then take off the short one, and finish drilling. repeat on the other side.
