PVC pneumatic or not . homemade mast for M109

[digitaldust]

any one thought of how to build a say 45 + FT mast.
I have seen pipe (PVC SCH 80 ) used but the plans are kinda crumby .
using duct tape to make a gasket on each 10FT pipe in side each other ?
i'm open to refine the idea

How bout gluing on threaded adapters so you can screw the ended together for a tight strong fit.

how would you rise this up ? tilt over ?

I like the telescopic trick as it has a smaller footprint

Yeah tilt up, as for gaskets could make some out of neoprene.
