The ballast keel box fabrication continues. After some careful measuring, I fit some supporting plates that will provide fixing points for the keel bolts. Sadly, the purchasing department is having problems supplying the steel needed to fabricate the curved leading edge of the keel box, but, oh well! Elsewhere, the quarterberth cushions near completion.

This is the story of the building of a Jay Benford designed, 31.8ft, junk schooner-rigged cruising sailboat. The videos are a week-by-week record of the build as it progresses and aim to show as much detail as possible of the various aspects of the build.

These videos take a lot of time and effort to make, in what is already a time-intensive project. Your support in watching, subscribing and sharing these videos is very much appreciated. You make a real difference!!

hi i'm tony this is svita badger
0:29
and i'm
0:30
leaning here on on the ballast keel
0:33
the keel for the boat the cruising boat
0:35
that we're building it's 32 foot
0:38
jay binford designed sailing dory and to
0:41
say this steel box will be the ballast
0:44
kill
0:45
and i'm here basically because we've
0:47
been working on on two fronts pretty
0:49
much this week
0:50
the ballast kill box is one of them and
0:53
i'm going to talk a bit about that in a
0:55
minute talk about what's going on
0:57
and what the what the future for this is
0:59
and the cushions quarter both cushions
1:02
in particular
1:04
um are now very close to being finished
1:07
at the very least which is which is
1:08
great looking good
1:11
let's start off with the ballast kilo
1:26
here
1:54
i'll be loving

4:02
[Music]
4:33
one
4:43
ready
4:50
[Applause]
5:08
so the battle skill progress and that
5:10
you've just seen um i put those
5:12
intermediate sections in there i've
5:15
actually also welded all around the
5:17
inside the bottom
5:19
um this week and put those sections in
5:21
there and those are all lined up and i
5:24
grabbed this big bit of wood here
5:27
i marked this out as a you know i don't
5:29
think i don't think you can see it but
5:30
there are various lines on here that
5:31
i've marked out from the
5:33
the wood keel from the kill wood
5:36
where the kill bolt holes go through
5:38
various markings on here so i could
5:40
transfer them to this metal box
5:43
and i put those
5:46
i put those intermediate plates in
5:48
slightly just slightly after where the
5:51
kill bolts are coming
5:52
i will then weld a bit of
5:55
substantial angle line to there
5:57
and that will give me fixings for the
5:59
kill bolts in the ballast kill
6:01
so that's coming on quite well i'll be
6:03
cutting some bits of that getting it on
6:05
soon but the one bit that really isn't
6:07
finished is the forward end where it's
6:09
it comes to this point but
6:11
in fact
6:12
it has quite a big
6:14
airfoil shape leading edge curve on the
6:18
on this angled front
6:21
and that's not even nearly in existence
6:24
and the problem there is i've ordered
6:26
steel strip to to fabricate that from
6:29
um but
6:31
there seems to be a shortage of steel at
6:34
the moment
6:35
not only a shortage of you know
6:38
computer chips and whatever else we hear
6:40
but still seems to be in short supply so
6:43
i ordered it from from crook tyson one
6:45
of the big steel suppliers in this part
6:48
of the world
6:49
and they've forecast that will be
6:51
delivered next week i hope this is true
6:53
so i can get on
6:55
with fabricating that that curved
6:57
leading edge and then there's one or two
6:59
more intermediate plates to put in
7:02
because there's a kill bolt comes right
7:03
at the forward end here a single one
7:05
another single one comes a bit further
7:07
after
7:08
so get that done
7:10
so
7:11
i hope that arrives next week i'll make
7:13
up a wood form of that shape lay the
7:16
strip on weld it up
7:18
and then grind it to its final shape and
7:19
get it on here and that will pull
7:21
everything up in line at the moment i've
7:24
clamped this big old bit of dug fur to
7:26
it just to hold it straight
7:28
and get the front end welded on that'll
7:30
hold it all nice and in line square
7:33
obviously got to make sure it is in line
7:35
and square
7:36
that's where we are so i'm waiting on
7:38
materials which is
7:39
always
7:40
a little frustrating
7:42
um i ordered the still a couple of weeks
7:45
ago and hoped it would be here but as i
7:47
say it isn't yet
7:50
hopefully soon and another thought is
7:51
just to respond to a couple of comments
7:53
from last week entirely sensible um
7:56
filling this this steel box with lead um
7:59
i do intend to melt the lead and pour it
8:01
in there but clearly you could just just
8:03
have small
8:04
bits of lead and cast them in in resin
8:08
for example epoxy or even concrete that
8:10
will work you wouldn't quite get the
8:12
density in both of those cases you
8:14
wouldn't get the density of solid lead
8:17
which you'll get in by melting the lid
8:19
and pouring it in there
8:21
but you get reasonably high
8:23
and of course the beauty of lead is it
8:24
is so dense this is what you've got
8:27
you've got to think you know we're
8:28
looking at 11 000 kilograms per cubic
8:31
meter lead
8:32
immensely dense
8:34
which means also it displaces much less
8:38
water for its for its mass
8:40
and i'll tell you a little story about
8:42
concrete
8:43
many many years ago a few decades ago i
8:45
did a little bit of work i was helping
8:47
out laying some moorings um for boat
8:50
moorings in turkey and what we did
8:52
we cast concrete blocks solid concrete
8:55
blocks uh
8:56
50 by 50 by 50 centimeters so an eighth
8:59
of a cubic meter
9:01
uh concrete is somewhere around 2500
9:04
kilos per
9:06
cubic meter so an eighth of a cubic
9:08
meter what we're looking at sorry like
9:10
in the region 300 plus
9:12
kilograms per block you know
9:15
and we took them out with a boat uh used
9:18
to use the bow roller and anger windlass
9:21
and whatever to winch them out drove
9:23
them out dropped them in the sea and
9:25
then i
9:26
uh scuba dived down there
9:29
and chained them together with shackles
9:31
and whatever but down below in the water
9:34
and it wasn't very deep it's five meters
9:35
deeper so down below i could easily
9:39
lift walk those concrete blocks 300 plus
9:43
kilograms
9:45
of concrete block easily walk run around
9:47
and you know and that's what you've got
9:49
to think that the displacement of the
9:52
water
9:56
has that opposite action doesn't it so
9:58
things appear
10:01
a bit too scientific here but it appears
10:03
to be a lot less heavy underwater so
10:05
some of it lead because it's so dense if
10:08
it doesn't shift that quantity of water
10:11
it's much more effective than a concrete
10:13
keel of the same weight because the
10:15
concrete kill will be
10:17
for at least four times as big clearly
10:20
you can mix things into the concrete to
10:22
make it heavier but you still won't get
10:24
to the density of lead
11:07
[Applause]
11:27
that on there
11:30
56 back that way
11:54
that should be our line
11:57
like that
12:18
like that
12:27
all right
13:00
uh
13:12
so
13:30
um
14:42
now
14:54
[Music]
15:04
[Applause]
15:15
[Applause]
15:27
um
15:52
hmm impression more sorry yeah
16:01
if you've been here listening to the
16:02
cock-ups that occurred
16:04
again but you wouldn't have said that
16:05
all right
16:16
[Music]
16:38
well we've got the quarterback cushions
16:40
sewn now
16:41
uh i'll spin the camera around and show
16:43
you those
16:44
uh karen's in the process of
16:46
sewing hand sewing the ends
16:49
so you'll see the very very aft one
16:51
actually the middle one is not quite
16:52
finished and the aft one is
16:55
not even start at the end but the rest
16:57
of the cushion covers done
17:03
but that looks really good i think and
17:05
uh it's a lovely birthday lion
17:09
really secure sea birth
17:14
and
17:15
i'm sure that'll get some use
17:18
there we are that's it for this week
17:20
sat in the quarterback it's a nice
17:22
little sitting spot i can imagine
17:25
perching in the corner here and reading
17:27
um thank you for watching we'll be back
17:30
next time
17:31
trying to push on and uh
