a couple years ago I made a mahogany and
ambrosia maple sofa table and today I'm
making a matching bench to use the table
as a quick laptop station in the house
the bench frame will be made from the
exact same ambrosia maple stock I used
for that build and this is actually all
that I have left and it turns out it's
the exact amount that I need the overall
style of the bench will be slightly
different than that table the base will
be the same design but the top it'll be
a little bit more interesting the
majority of the work will be done with
the ambrosia maple so that's where I'll
start first joining one wide face and
then both adjacent narrow faces then
it's over to the bandsaw to rip the
blanks into about one and five-eighths
of an inch square and then back to the
planer to establish a one and a half
inch thickness in both directions at the
miter saw a fresh 90-degree end is
established and then the legs are cut to
the final length as I already said this
material is just leftover material from
the table build that means I don't
really have a choice about grain
direction I just have to use what's
available but as it turned out on the
leg blanks we're 100% perfect with
matching rifts on grain all the way
around I could not get any better than
this
even if I tried to pick out stock
definitely a happy accident here what
i'm doing here is marking the location
for each of these sliding dovetails as
well as a carpenter's triangle in the
middle to instantly let me know where
each individual piece belongs at a quick
glance next up is the rails the only
piece I had left was already planed to
seven eighths of an inch thickness and
it unfortunately had a little bit of bow
to the board rather than chasing the bow
out of the board at the jointer I
decided to just skip playing it down to
the final three quarters of an inch
thickness and my thinking here was that
I would rather have a full 3/4 inch
thickness and a very slight probably
unnoticeable once assembled bow on the
final length pieces rather than joint
and playing the bow out and be left with
thinner material the board was then
jointed on one long edge and the rails
were ripped to a smidgen more than the
final width at the table saw and when
working with figured wood like this it's
pretty exciting to be able to shift
pieces around to get the look that
you're after in this case I was able to
lay out four really interesting grain on
all four rails then it's back to the
miter saw to cut the pieces to their
final length I rip the pieces to a
little bit more than the final width
because I knew that the table saw would
cause some burning on the maple maple
and cherry are notorious for burning
easily against woodworking tools but
with a few passes of a hand plane all of
the burn marks they're completely gone
and not only are all the burn marks gone
but all of the machine marks from the
planer and table saw they're gone as
well a smoothing plane is much much
faster than sandpaper when it comes to
material prep like this now of course
that's assuming the wood grain is not
going crazy and in multiple different
directions
the rail - leg joint will be a sliding
dovetail and both sides of the joint
will be cut using a single template the
inside of the template allows the
negative part of the sliding dovetail to
be cut and once a test piece confirms
the correct setup all eight of the
negative cuts are bashed out quickly
then the machine is set up to run on the
outside of the template for the positive
part of the sliding dovetail again a
test piece is used to dial in in the
perfect fit
now the fit I was going for is a really
tight fit that doesn't require a mallet
for dry assembly when hide glue is used
it will slightly lubricate the joint for
assembly but due to the thickness of the
glue and the already tight fit of the
joint a mallet may be required and once
again all eight cuts of the positive
side of the joint are batched out
quickly next both long rails are clamped
together with the top faces touching and
then placed in a vise this will allow me
to easily lay out all of these slat
locations on both front and back rails
at the same time and the layout consists
of two inch wide by one half of an inch
deep cuts for these slats spaced one
half of an inch apart to keep symmetry
each end cut will start one quarter of
an inch in from the sliding dovetails
and the bottom of these end slits will
be lined up with the top of the legs
during assembly to make these slat cuts
I'm setting up the machine to restrict
the horizontal cut to two inches wide
but also allow a vertical travel inside
that two inch restriction now the bit
can be lined up with the layout lines
and a partial slack cut on the end can
be made
then the piece is repositioned for the
first full slat cut and I found the best
results were achieved by making a
typical mortise cut first then backing
out lifting the bit so the center was
slightly higher than the top of the
material plunging full depth then
plunging top down to clean up the
leftover material and this sequence
resulted in zero tear out on both sides
of the cut then it's just a matter of
repositioning the material and repeating
the cut
[Applause]
now for consistency's sake and to cancel
out any error i make during lining up
the bit with my pencil lines I made sure
to cut one rail from left to right and
the other rail from right to left this
means that the cuts will be made from
the same side of the bench and therefore
increased precision of slat alignment
this dry assembly shows the slat cuts on
the front and back rails lining up with
the top of the legs and it also shows
how much the side rails need to be
trimmed to match the top of the legs
also using a metal hammer here isn't
really a big deal as not only is the D
maple pretty hard but both the top and
bottom faces they'll be covered and I'm
making sure to not hit the edges to
quick cuts at the table saw and the side
rails are ready for assembly one of
these simplest ways of making a leg more
interesting is by adding a taper there's
many ways of cutting a taper but I
already had a specific size taper block
for the bandsaw that matched the
dimensions I needed so that's the route
I took and just like the last cuts at
the bandsaw the tapers were cut with a
smidgen more material left on the leg
than the final desired amount here you
can get a good look at the taper as well
as the nearly perfect grain appearance
on the legs back at the work bench the
tapers were quickly cleaned up with a
couple passes of a smoothing plane
[Music]
the rest of the routing will be done at
the router table and with just two bits
the first is a 1/8 of an inch roundover
a bit for the legs followed by a 1/4
inch roundover bit for these slats and
the top of the long rails the legs
receive the 1/8 of an inch roundover on
all long edges as well as the bottom of
the leg now since getting a 1/8 of an
inch roundover bit in my shop i use it
on the majority of everything that I
make it breaks sharp edges without
giving the intentional rounded
appearance meaning that the pieces can
still maintain a blocky or a straight
and flat appearance but still have an
edge that's a little bit more inviting
to the touch for the top of the long
rails I installed the 1/4 of an inch
roundover bit and buried the infeed side
of the fence into the bit this will
provide a little bit more support to the
back of the cut and therefore reduce
tear out now I was a little bit nervous
of the step because these rounded edges
were part of the design and any tear-out
would be extremely noticeable and in
this case nearly impossible to fix the
final results were absolutely perfect
though zero tear out and I was very
pleased
finally the frame is assembled with hide
glue and just as expected the thickness
of the glue and the tight fit of the
joints made the use of a hammer
necessary but at the same time the
lubricating properties of the hide glue
meant that I could take it a little bit
easy with the hammer
no clamps necessary just get the top
edges to line up and set it aside
with the frame set aside I'm milled to
the mahogany slats now I'm not 100% sure
that this is mahogany while building it
I I thought it was a soupy Lee due to
the predominant streaks in the grain but
after analysing the completed project
next to a coffee table that I made where
I know the wood was African mahogany I
honestly just don't know at the table
saw I sized the pieces slightly wider
than the slat cuts on the frame so that
the narrow faces could be both cleaned
up and the perfect fit established with
the smoothing plane at the workbench
back to the router table to cut the 1/4
of an inch roundover on all long edges
of these slats followed by cutting these
slats to their final length at the miter
saw now I got these two steps backwards
I should have cut to length first and
then routed the edges that way the
router bit would clean up the tear out
caused by the dual miter saw blade that
I happen to be using alright so let me
just jump in really quick and talk about
this design so I made a design video of
designing this and Sketchup and that
video is on my second channel I'll have
a link in the description if you want to
see this designed in Sketchup and in
that particular design video or the
making the design itself okay I was
really excited about one specific
feature and that is this exposed rail
with the slats sitting down into the
rail and everything being rounded in
opposite directions it was a you know
this is amazing kind of a design element
I thought it would look really really
cool once I got it built I'm just like
Generic right it's okay it's not bad but
it didn't have that wow factor which was
a little bit disappointing sometimes
that happens so I put the brakes on this
was completed at this stage last I think
Thursday today is Monday when I'm
recording this so I put the brakes on
let it sit over the weekend kinda and
see if I can think of something to make
it more interesting
my solution which my solution is to
recut the slats out of some more
material that are a full inch longer
than what these are that will allow me
to create an outside curve on both sides
of this bench then with them sitting
down in place and not secured everything
exactly where it needs to be take a
piece of 3/4 inch plywood with that
exact same radius on both sides and some
double-stick tape and sit it set it down
on top of all of these so that I could
lift them all up and then remain in
their orientation their final
orientation flip that piece of plywood
over and put some scrap material
over the top of this perpendicular to
these gaps and screw through the gaps
into the plywood basically creating some
hold downs to really securely hold these
in their exact final orientation then at
that point I guess cut the curve on
these pieces and then take the piece of
plywood with everything screwed down to
the router table and cut a taper on the
on the cut edge so it'll be a curve as
well as a taper and the way I was going
to accomplish that was instead of
tilting the router I was gonna tilt the
table by simply putting a shim or a
spacer on one side of the table sticking
down to it and then that plywood would
rest against the bearing on the bit and
on top of this piece of plywood
elevating it kind of tilting it a little
bit that flush trim bit would then
create a slight taper to the bottom edge
of this curve that sounds like a that
sounds like an appropriate process to
accomplish that but before I did that
I've actually modeled what I was
thinking and Sketchup and it just
doesn't fit it just doesn't look right
it looks too out of place compared to
the base so with all of that said I
think I'm just gonna stick to the
original design sometimes things aren't
as spectacular as they may originally
appear but they're still pretty good
this to me just looks like an outdoor
table with slats for rain to fall
through that's fine I'm gonna use it
inside as a bench to use my laptop at a
sofa table that I built previously and
it looks pretty good it just doesn't
look as amazing as I thought it would so
I figured I'd throw that out there and
this will look a heck of a lot better
with more contrast
once the finish is applied it to the
whole piece this mahogany will really
darken up I actually I think it's soupy
Lee it'll really darken up and I still
have to put the little decorative strips
down here so that's it I'm going to
knock this out with a quick the last
piece is needed before assembly are the
1/8 of an inch strips that will be glued
to the bottom of all of the rails and
this is one of the many reasons why I
think a 2 by 6 push stick is the best
all-around option at the table saw the
sacrificial flat bottom of
2x6 provides stability and holds down
the material on both sides of the blade
while allowing the blade to cut right
through the push stick the sacrificial
hardwood cleat on the back edge of the
block provides a mechanical connection
to prevent slipping of the push stick
over the workpiece as it's being cut and
you can easily cut strips 1/16 of an
inch or less between the blade and the
fence safely and easily pick up yours
today for free at your nearest scrap bin
the glue that I'm using for the rest of
the project is a quick setting glue that
dries clear to reduce squeeze out on the
outside I'm only applying a small bead
of glue close to the inside edge finally
these slats can be installed and the
same glue technique is used just a
little bit of glue near the inside edge
and this is a long grain to long grain
glue connection so it should be plenty
strong as is and in my initial Sketchup
design I planned on using screws to
attach the slats but decided against it
mainly for looks I think not using
screws will look a lot cleaner and I
honestly don't think they're needed for
strength and of course if by chance the
glue only strategy just doesn't work out
long term I can always drill and add
screws later the final step before
finish was to do a once-over with a fine
grit sandpaper just to take care of any
problem areas and for a finish I'm just
springg shellac nothing fancy I ended up
spraying two coats of seal coat shellac
and literally that's it it's plenty
enough protection for the way it will be
used and it still feels like you're
actually touching wood instead of a
plastic feel that polyurethane can
sometimes give now the secret sauce here
or the main takeaway here was that
cleaning up all the phases as I went
with either sandpaper or a smoothing
plane made this finishing process
extremely painless so here it is in the
house and excuse the lack of cable
management this is just a temporary
location for the table as our Christmas
tree is up in our living room but
overall I think it I think it looks
really good the wood combination matches
perfectly and because the bench top is
different it provides something else for
the eyes to inspect and of course my big
ol butt fits on it and I
finally have something to sit on for a
quick laptop session in the house also
here you can see it next to the African
mahogany top coffee table that I made
previously so what do you think is its
appeal E is it mahogany now that I look
at it while editing this video I'm
leaning more towards it just being
mahogany and not sappy Li but then again
as I was making it those streaks really
are you know very characteristic of
sappy Li so who knows so I think that's
it for this video if you want to stay up

for my email newsletter I publish a lot
more on my website that I do on this
particular YouTube channel if that's

that is definitely it you guys take care
and I'll talk to you later
