My current physically based quest is calling chemical and medical suppliers in my area for rigid PVC 1/4" tubes, to support the gap between reflectors in a GH10 or DBGH. Does anyone here have experience finding or using this sort of material?
Best Plastics, Composites, Rubber for structural antenna parts
Just a warning note about using ABS for structural parts that I've mentioned many times before - hopefully what you're planning to use is the thick walled stuff that has little or no flex. If you go to Rona or Lowe's or Home Depot and shake a 10 foot ABS pipe like a sword it flexes a lot. 
It seems to be rigid, but its not. If you shake a length of PVC like that it will seem like a wet noodle, so avoid using PVC for structural use either, except when recommended in build plans.
From experience I'm clarifying that ABS should never be used as a pole or mast, and it should be carefully considered if you're thinking of using it as a horizontal boom of any length more than a meter or a few feet.
