[Shop-talk] How to Make Water Flow Downhill

[Doug Braun]

BTW, I recently read of a nice way to make a through-bulkhead PVC pipe flange.
You can easily get a PVC fitting that goes from a glue-in socket to male or
female pipe threads.  But the threads are tapered of course, so you can't
really use them like a nut and bolt to go through a bulkhead.

The trick is to
get the equivalent PVC fittings for electrical conduits.  They fit the same
size PVC pipe, but have straight threads.  Then you can drill the
correctly-sized hole through the barrel, pass the male fitting through it, and
use a female fitting as a nut to hold it in place.

This trick would help you
make a 1" or 1.5" dropshaft.
