Thanks Paul! Wires are also sealed with o-rings, using the same concept as the polycarb/aluminum plug seal. A hole with a deep countersink is drilled where each wire will go, and the hole is sized to compress an o-ring around each wire. See the diagram I attached for a cross sectional view. In one o...

Another approach you can take to constructing manipulators is to use an already sealed motor (bilge pump) and use "wet" mechanical reductions to slow it down. You don't have to worry about sealing anything with this approach, but the manipulator can get pretty bulky. Here are two examples ...

Paul, We have built several camera housings using a polycarbonate tube with aluminum plugs sealed with an o-ring. When the o-ring is compressing against the inside of the polycarb tube as in your picture (and mine attached) we haven't found a need to smooth or buff out the polycarb. This is with a 6...
