Doh! And I did try really hard searching the forums for anything on this subject! Should've tried "Coaxial" instead of just "COAX". Thanks for the ref iScrap! That's exactly the stuff! I have about 100' of this stuff and it is solid circle corrugated.

In addition, I also found about 10' of the 2" stuff which had some sort of resin between the PVC pipe outer layer and the corrugated copper. Had to cut into 1' pieces and pull out the hard plastic interior which wound its way around inside. In winter time I bashed off the resin coating which came off nicely in the cold temps.



Thought about the cutting wheel Midnight. Maybe somehow fix an angle grinder into a solid position and then pull it through something that would apply pressure on it against the wheel as it's running. Sounds like a two man job.
