Hi Tim,Sure can do.  I am doing pretty much what Alan shows with a couple exceptions, I use threaded rod and I encapsulate the wet end of the rod where the wire bolts on in high compression casting resin.  At least that is what I did on my new sub "Elementary 3000"Hank

Subject: Re: [PSUBS-MAILIST] Electrical thru-hull  Hi Jon,You have a couple of options, you can machine a piece to fit with an o-ring groove in it and make a penetrator from that or you could thread your opening  and make a penetrator to fit that.  How many wires do you need to go through?    I would not use a smooth rod in a home made penetrator.  I always use a small threaded rod and have had good success.  I tested the two I made for Gamma to well over 600 psi and they were perfect.  If you like I am happy to make you a couple to fit your bore.  Just get me the exact measurement of the bore.  You have been very helpful to me and others so it would be a pleasure to help you out.Hank  On Saturday, February 6, 2016 2:49 PM, Jon Wallace via Personal_Submersibles <personal_submersibles at psubs.org> wrote:  
Hank, 

See attached.  It's just a smooth bored thru-hull sealed on the outside face by an o-ring.

| Jon,
What do you have to work with in terms of hole in hull. What amp are you trying to run through.
