A look at the keel design that I've selected to put on Tapatya, hopefully clearly explaining the way it's going to be. Also a look at the Jellas belt sander.
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!!

and we're now in a very very pleasing
situation having
a piece of the kill wood running all the
way from the forward end
all the way back as far as the cell
drive leg
[Music]
we see it all in black and white
[Music]
i'll make the
[Music]
hi i'm tony this is svitapaja and as you
may well know we're building this
cruising sailboat a j bimford designed
31 foot eight
cruising
dory sailing dory uh junk schooner
rigged will be
and as you may also well know the last
few weeks have been all about uh
concentrating on the keel
and uh judging by one or two comments
um i get the impression that some of you
are not completely clear what's going on
with this cure sir so the big goal of
this video is to
get some clarity on the keel structure
and design
let's start there now to all intents and
purposes all boats have this curve along
the ball sailboats have this curve along
the bottom line known as the rocker
maybe one or two exceptions but they
basically all have it this bottom line
is curved and one of the first things
for this kill structure was to fit some
pieces forwards and aft to level that
out so we can finally get a straight
piece all the way through and that's
where we got to last week with this
this is the bottom piece here is a long
six meter long piece
going from the forward end all the way
back to just forward of the cell drive
leg gives us a flat
level surface under there to attach the
rest of the keel to and the rest of the
kills can be made up in the workshop
uh some more kill timber and the ballast
kill
led to ballast so i guess one question i
should answer is is why am i doing it
like that
because indeed most boats are built from
the keel up
which is true
but uh this method is not from me this
is following the the method
stipulated by the designer or suggested
by the designer and i support it 100
it makes total sense and as jay bimford
says you know it allows you to keep the
boat lower in the shop as you're
building it and this is we're in my shop
here
it's
maybe 10 foot 12 foot high 12.6 12 foot
high maybe at the highest point
you know so the boat had to sit fairly
low in here
um you see sometimes in boat yards don't
you see these
multi-storey tarpaulin sheds where
people are working on their boats
but the beauty of this was it could sit
low in here this in fact is the ladder
that i used for going up onto the the
forward or the aft deck up to the
cockpit you see the height i think it's
about five foot high i suppose
that was
the height of the decks
it was very very easy to get materials
up there
and back down again and when you're
building a boat you're spending a lot of
time going up and down onto the boat
back down to get things to work on
things to machine things taking them
back up again
and it makes it very very easy so
keeping that low in the shop is is such
an advantage
and yeah i support that all the way
and then of course because you've done
that you then
get the keel afterwards which is where
we are so here we are
and
i hope you can recognize this as the
beautiful drawing of a of the outline of
a benfidori hull not to scale
uh i've got the rudder hung on there
and it was an approximation and
see we've got this rocker on the bottom
and let's have a cell drive like coming
through there shall we
there we go so driver leg
got this rocker on the bottom
and what we've done so far is we've put
in three pieces forward
coming through here somewhere
three pieces forwards
one piece at the aft end
through there somewhere
and then one piece
from there
rubbing it all the way through
like that
so we've got this flat surface
underneath now clearly that the boat's a
bit shrunk put them in terms of length
but that's what we've got on there
and then in the workshop
the task will be to make up
some more pieces that fit to that that
come in should we sound onto here
when it's fitted on there we'll come in
something like that
this is made up of five planks two
three four five
one two three four five
five planks laminated up solid wood
there we go
that was easy enough then we need to
make a ballast kill ballast kills i'm
approximating where it comes to it's
coming in there
palace kill is a great big lump of lead
1280 kilos is the designed
ballast
that's what we're aiming for or possibly
a fraction more
um but in that region
and behind our ballast kill we've got
this comes down a little bit more
now from here on
these taper down to uh to give us a sort
of an airflow shape we've got a curve at
the front and a taper there gives us a
sort of air force shape to the entire
kiln
and then the last piece
comes through here
under there
like that
and supports we've got a bronze rudder
support shoe a couple of pin tools on
there
three position support for the rather
good and solid ocean worthy
so that's what this is looking like and
this remember is laid
the lid is bolted up through the whole
lot with
now i've adapted jpenford's plans a bit
i'm putting 11 bolts i'm putting two
i'm putting one i'm putting two
that's five
but one
one
seven
two
and two nine eleven okay they come down
a bit further in the lid than that
come down there and they go up through
the floor timbers
they're all lined up nicely with the
floor timbers
bronze bolts embedded in the lid
nuts on the top big washers or some kind
of plates to spread the load
and those keel bolts hold the whole
thing up together it's quite possible
that i'll embed
a bolt
in the wood there
and now where i've got enough
meat to get an embedded bolt in embed a
couple of bronze bolts in there
um and that's what we're doing
as it stands the leveling out pieces are
on
and
this freak has been working on this
wood section here
i hope that's clear
uh
[Music]
wow
[Applause]
so having roughed out those five boards
next job was to mark the uh the kill
bolt holes
which involve taking the uppermost one
of those the longer one of them
out to the boat
fixing it in position underneath and
drilling through the various holes just
to mark the position of those
those bolt holes before could laminate
those five pieces together
[Applause]
shouldn't get that jacked up
[Applause]
[Applause]
[Applause]
[Applause]
[Applause]
[Applause]
[Music]
well a very strange thing happened this
week
something that
was quite a surprise
a company uh this company
jealous
if that's how you pronounce it
wrote to me
and uh they obviously found my email
address and asked me if i'd like to
try one of their tools and give it a
review
let me say this straight away
any tool review i've done up until now
has been completely independent you know
i've got nothing from any company
anywhere up until this stage so
this is the first time anything like
this has ever happened weird but there
we go
so the there had a list of a few tools
and i
thought the belts and
most of it was stuff i already had
but and i've already got a belt sander
but i thought it'd be kind of nice to
have another belt sander a lighter one
and one that could be clamped to the
bench maybe to use as a bench sander
so
they sent me the belt sander
and here it is
well here's the box
and first thing
i'll say is
you know far from the most important
thing but i think the box is good in
that there's no glossy print on it
looks like the sort of box that could be
recycled easily
when we open it up what we've got of
course
unsurprisingly is a belt sander
a dust bag
a couple of clamps for clamping it to
the bench
this is unusual comes with half a dozen
one belt on the machine and half a dozen
spare belts that's quite something
and the vacuum cleaner attachment
plus the
destructions
um let's have a look
well it's light compared to my makita
which is a beast of a machine let me
grab it for you
here's my makita it's you know it's a
beast of a machine weighs a fair old
chunk
this one decided lighter um
[Music]
you wouldn't want to swing it too long
with one hand but it undeniably lighter
and
i've used it a little bit tried it out
it works
well i couldn't possibly comment on is
is its longevity of course it's
um i've had the thing just over a week
now and
it seems fine but i have no idea how
long it'll last as anyone's guessed
i don't know these things by trying them
but
quite good
felt release as you expect on the lever
there
felt tracking adjustment on the knob
there
speed adjustment on the forward handle
let me hold up there one two six i
believe
doesn't go to 11.
and you know
the usual buttons turn on with the with
a little lock thing there
lock it on
nothing surprising about it
it comes with i say these clamps
so you can
clamp it to various positions that you
can clamp it from
suppose you're clamping why would you do
that
that's the one i use i use those two
there
clamp it down
um to a bench
i would like
and this isn't this company's fault but
i'd like i'd like a belt sander to be
able to be clamped
like that
and i have had a good look around
and i don't see any possibilities clamp
it like that
but you can certainly clamp it like that
and use it upside down
and the clamps you know
seem to be up to the job
dust bag is
[Applause]
rudimentary
but i suppose the vacuum cleaner
attachment will be better
if you're keeping the dust down
um yeah
it's fine
it's fine jealous belt sander they have
a few other tools they've got an orbital
sander that looks like a copy of the
dewalt that i have
um
what can you say about it it sands
so plugged it in now and uh give it a
spin
[Applause]
quite a breeze comes out of the motor
um
from the airflow the cooling flow
through
through the motor
if we compare it to
the mckeezer
[Applause]
the
makita the air comes out the sides there
this one comes out that way
surprisingly the makita's quieter
i suspect these are quite a bit cheaper
and will probably do the job
yeah
swinging door catch
quite nice quick hands hand
ah
[Music]
so
[Music]
thank
[Music]
[Music]
much
do
[Music]
so
[Music]
[Music]
and here it is
in all its glory
five fairly heavy-duty douglas fir
boards laminated up epoxy glued
thorough epoxy gluing job wetting out
the surface and then putting some
thickened glue boxy blue in there
clamped together
and uh next job will be to fair it up to
clean it up got a few dribbles there a
lot of dribbles
clean it up fare it
put a filler here and there if necessary
drill the keel bolt holes through all
the way through
and then that will be that one done cut
this cut this obviously that's a steady
angle and later it is shaped to her to
an airfoil leading edge shape
i should do that when i've got the
ballast kill cast and make sure they
match
but uh
there it is that bit didn't take very
long and i hope that has brought some
clarity to the keel
it for now thanks for watching if you'd
like to support this channel give us a
thumbs up leave a comment
it all helps i believe in the old
youtube algorithm
um or if you'd like to go the extra mile
over on patreon we have three tiers of
support
uh get over there and have a look it's
also do a behind the scenes video i'll
just get on with it
um
we'll be back
see you next time
bye
[Music]
[Applause]
[Music]
you
are okay
[Music]
[Applause]
