Giving the blog a kick.
I’ve been trying different social media, have concentrated on Facebook
for the last while, but it’s a mixed blessing and many people don’t like
it. So, I’ve got the Yahoo Jwbuilders
group going again, its still showing 4500 or so members but I’d neglected it
somewhat, as with this blog. But the
three media seem each suited to somewhat different purposes and I figure that
there is a place for each.
So, here on the blog you’ll find news of my builds and
adventures both in design and cruising,
those are essentially an archive.
On the Yahoo group there will be question and answer plus that
incredible photo archive that can be so helpful to a new builder trying to find
an answer, and on Facebook, we’ll chat.
How to keep all three going? I suspect that I need to figure
out a way to be awake and productive 24 hours a day 7 days a week, but we’ll
see.
I had a great summer, three cruises on Spook, one in the Bay of Islands, one in Kawau Bay. That one just an overnight to see how my little dog would take to life on a small boat, and to check out Spook after her long layoff and several mods to the rig, and also to check out the inflatable kayak. That wasnt a good thing by the way, I've since bought a rotomoulded plastic one, have yet to try it out, so "watch this space".
The third cruise was across to Waiheke Island, the home of the best ice creams on the planet and some of the best scenery you'll ever find.
That took me away from the boatbuilding shed. Worth it though.
So, I’d been a bit stuck on two little problems, I had
issues with accessing the lower rudder fitting bolts from inside, once the deck
is on this area will be darn near impossible to access, I had visions of
welding up a fitment that would hold the bolts from inside, in such a way that
I could wind the locknuts on outside when fitting the gudgeons to the transom,
and as I don’t have the gear to weld stainless steel ( yet, its on the list)
I’d put that task off until, hopefully a flash of inspiration would give me a
better idea.
While at a friends place, I spotted a strip of scrap
stainless steel, 6mm x about 25mm, just eboug enough to do what I had in
mind. So, hacksaw, files, drills and 6mm
metric fine taps came out on the bench and I’ve built the three fittings you
see below. The stainless straps are
screwed to the inside of the transom, the bolts come through the gudgeon
fittings, through the bolt holes in the transom and screw into the tapped holes
in the straps. That way I’ll hopefully never have to rip the deck off to get
back in there to tighten or replace nuts and washers.
There will be a countersink in the bolt holes on the
outside, a sealant will form a big gasket,
allowed to set at about 2mm thick before the bolts are tightened and
hopefully that will mean a permanent installation with no leaks.
I’d mention too, that I drilled the bolt holes out at 20mm
diameter, filled them with thickened epoxy and re drilled them to take the 6mm
bolts, this considerably increases the
strength plus prevents any water getting into the plywood end grain.
Next job. I have, after a complete change of batteries in my
old ship, a big 660 CCA truck starter battery that’s still in good order. Its one of four, and two of the others which
are on a different circuit, had failed so I replaced the lot. That leaves me with a $350 battery that
testing showed to have a lot of life left in it, and a boat in build that will
have a solar panel charging system, lights in the cuddy, a light in the forward locker on each side, a
GPS chart plotter, a VHF/SSB radio, navigation lights, phone and laptop
charging points and an electric bilge pump ( in addition to a big manual
one). That’s a fair bit of electrical
demand, and it seemed a good idea to put
the two together.
But here is the problem, the battery weighs 22 kg, (48,4
lbs). How to fit it into its space,
secured well enough to ensure that it doesn’t come loose should the boat be
knocked down, and yet be accessible when I need to pull it out and put it back.
I’ve built a box, it has a lip along the top side edge and a
“door” on the other, also with a lip. The box has tapered bearers to fit the
curve of the bottom and side, is to be held in with bolts through the adjacent
bulkhead and the centreline web on which the main mast step is mounted, and the
door in the side opens to port, leaving just enough space to slide that big
lump of a battery into place, and close the door. I’ve a cleat on the top edge of the door
which takes lashings that come across from the centreline web so once in and
the lashings on, its there to stay.
Here's the battery box, its not bolted in yet but its a good fit to the curve of the bottom, the centreline web and the angle of the lowest plank so is well supported. Oddly enough the real risk is not while sailing, its being bounced around while the boats being towed on its trailer on my way to another adventure.
The battery has to be lifted though that hatch opening on the right, placed in the box and the door closed as below, then the door lashed closed to a cleat, yet to be fitted, on the centre spine. Its the lip on the door and the lip on the back wall of the box that holds the battery in place within the box.
The electrical feed to and from the battery will go up the
side of the mast box to a plastic kitchen container, through holes in the side
which will then be sealed around the wires, to a bus bar set. The container has a removable lid so I will
be able to get at things, the wiring then goes across to a switch set mounted
on the inside of the hatch so when I want to get at it, I open the hatch, press
the switch and close it again. All
secure, out of the wet, but accessible.
I’ve begun running wires, there will be quite a lot of them,
and all this needs to be done before I put the side decks on.
