I drilled 2 holes per pipe. One at each end. In the same place I drilled throught the wood. I then got 2 nuts and 2 bolts and puit them through the holes and tightened alot. My rail holds up great.
Put a broom handle into the pipe and screw from under the wood into the pipe into the broom handel. Maximum support, yo.
Also getting a name more creative than freeskier18 might get you somewhere.
