Electrical Prep

This weekend allowed for some time on the boat.  Last weekend I only had time for sanding on the boat which doesn't allow for very interesting reading or viewing.  However I sanded all of the teak cockpit hatch seats that could be removed from the boat.  Then i sanded all of the teak cockpit combings.  They will require another final sanding before stain and varnish.  I also this weekend discovered by chance how to remove the hatch so I plan on taking the hatch and doors off the sand and varnish with the seats.  I ordered enough varnish to start the job.  probably not enough to finish it all.


The other big news was the order of all the electrical wire came in.  So now I have two completely different jobs at hand.  One is dirty and outside.  The other is clean and inside.  The electrical required some prep before I was ready to begin the install.  I had installed the battery boxes with the straps provided.  They were junk.  Cheap plastic with difficult buckles and poor mounting.  I made new straps from commercial tie downs.  I cut off the hooks on the ends and melted in some screw holes with a hot nail.  These I attached with SS screws and washers to the backer boards and now have a very strong, positive locking tie down that I know won't come loose in a sea way.  I had an extra one so I made an additional tie down for the forward water tank.  The rear of the tank is secure under a support beam but the front is technically loose.  My only flaw is this will work it's way forward and slip off so I need to add another strap to keep it tied back.





I created a lateral path through the starboard side of the boat under the settees and through all of the bulkheads.  I used 1-1/2" PVC tubes cut in 3" sections to create a channel that would support and guide the main wire bundle.  They were screwed onto support pieces that were already laminated to the hull and epoxied into place when penetrating a bulkhead.  The edges of the tube were sanded down to minimize any chafe. With the left over epoxy I adhered the two 10 gang pos. and neg. busses to the exterior hull.  I ran the battery positives and the main negative last night.  I will label them tonight and continue to run the additional wires as needed before beginning the job of crimping and soldering the ends.  I still need heat shrink tube and solder.  I also need to understand what size post will come on the batteries.  I don't want to pick up the batteries till the end of the job so they are not sitting around aging.
