If you did ... the technique for getting the PVC pipe out is as follows. To allow the glass to release over a long run first lay a single layer of light glass over the PVC and let it cure. Cut through this layer and move it around till it is released down the full length then reposition where you started. This is now ready for the final layers of glass for easy removal of the pipe. All you need to do now is fill in the ends. I'm going to use this technique for CF torque tubes.
