[PSUBS-MAILIST] elec thru hulls

Brian,Those look very nice, and you will enjoy filling them with epoxy with such a big throat.  I have to use a syringe in some cases.  The only critique I could have is, I always thread the inside of my penetrators.  I have no idea if it matters, but my theory is, the water has a tougher journey to make going over threads and the epoxy has more surface area to grab.  Hank

 Hi Brian,I am not an expert, but I use a small gas torch on the heavy stuff.  Just heat the rod & wire up well first. Hank or someone else with experiencemight want to comment, but I would wind the wire around the rod & solder it then cut back any excess wire sticking up after soldering.Alan

Hi Alan,       There is a larger diameter bore on the ocean side yes, goes from 1 5/32 down to 7/8" .   I'm going to run the wires thru a vinyl tube filled with oil .   I think I'm going to need a heavy duty soldering iron to solder the # 5 wire to the 3/16" solid rod however!  Not sure if my little iron is up to the job ! Brian

Very good Brian.Is there a step or cone shape in the seaward side of the through-hull tokey in the potting mix? Also how are you coating the wiring coming in tothe through-hull.Cheers Alan

Hi All,                Been working on my electrical thru hull penetrators.  I'm going to have three 3/16" copper conductors going through them.  I still need to pot the conductors in.  They are going through a 1 1/2"  aluminum disk which is exactly the same size as my acrylic viewport . Here's a pic: Cheers, Brian
