Hi Brent. I'll be using female/female bell reducers with the small end
threaded onto the nipple, and the large end receiving a hose barb fitting for
attachment of the clear plastic tubing.
The wires that go thru the epoxy aren't really wires, but are copper
threaded rod, so the epoxy sticks and holds the rods in place, and the surface
area of copper to epoxy is greatly increased. Plus, the copper all-thread is
easy to find, they have it at the local hardware store. The wires connecting
from the potted rods to the batteries ( inside ) or to the motors ( outside
) have a longish socket type connector to minimize resistance and heat
build-up. I don't think you can just put wires in the epoxy, that will leak
under high pressure. You need a shoulder or threads or something to keep the
rods sealed in the epoxy. With oil compensation under high pressure, it's
possible for the oil to be pushed past a smooth wire in epoxy. Frank
