I'm Tom Johnson, Thomas Johnson antique
furniture restoration in Gorm, Maine. As
you can see, I'm back to work on the
shop working on this table. In fact,
this will be a new video. But I have
been doing some furniture. I repaired a
chair for some friends of mine. Let's
take a quick look.
Heat. Heat.
Heat. Heat.
Hey. Hey. Hey.
bang.
Heat.
Heat.
And this is where I'd love to show you
some footage of me finishing the doing
all the color work on this foot using
mohawk toners, but that video footage
has been lost. So, we'll just have to
settle for these uh beauty shots of the
finished foot.
And on the subject of chair repairs,
this video you're about to see, I really
like a lot. It shows me repairing the
leg of a 235y old federal period side
chair. And I do it without really
altering the chair and without affecting
the finish. And it's important to save
the fabric on this chair because it's
one of a set. And note how I devised a
clever method for locating the position
of the leg during a glue up. You know,
both these videos show all the
difficulties you can encounter repairing
chairs and especially considering the
stresses that they're going to be put
under when they go back into service.
Hey, if you enjoyed this video, hit

really appreciate it.
This is a very nice antique side chair.
Uh, one of a set of eight. It's federal
style, which means it's from 1790, 1800,
that time period there. There's a lot of
very nice carving all over it, probably
out of New York.
And uh what's happened here is this leg
has snapped off.
This whole part of the leg
goes up in there and joins to the rails
has snapped off. And not only that, it's
been repaired before.
So, I have to figure out exactly what
I'm going to do. And I don't really know
that until I start pulling back the
fabric somewhat. I need to see what's
going on in there.
Now, the first steps uh always going to
be to
protect this seat. I'm going to cover it
with plastic.
Typically, I'll reuse plastic many, many
times over, but in a case like this,
this is time for a new piece.
So, what are we looking at here?
This is the broken piece that you know
we see
on the leg itself.
This is a tenon
going to the front rail. There should be
a tenon for the side rail here. I don't
see it. And I don't know what this
substance is right here.
I'm going to sketch this out.
So, what I'm doing here is I'm drawing a
cross-section of this leg and
specifically the joint. Cross-section
means
you slice an object this way and then
look straight down on it. And that's
what I'm trying to draw here.
So really, I'm just kind of working out
what I'm going to do. This is the
outside perimeter of the leg.
This is the part that we see right here,
the broken part.
This part of the leg, we don't know. I
assume, I haven't seen yet. This is a
tenon from the rails. This is the tenon.
Originally, there should have been this
much leg there. Depends on how far they
brought these tenons out. I did a video
called too many tenins, which discusses
this very issue, which,
you know, it's tough to get around. So,
I'm going to start scraping away.
So, I want to start scraping away this
part here. I assume that this wood is
the original leg. Here's a tenon. We
don't know how far that tenon goes. I
want to see what we've got here.
Well, as I thought it might be, this
looks like end grain. This too, I guess.
And so this is the part of the original
leg
um represented in my drawing drawing.
It's this area here. So of course we
still don't know how long the tenants
are, but
I'm wondering if I should use this area
here.
And so back to the leg again. In other
words, I'm kind of thinking of redoing
this repair the way it was done before.
But I'm wondering if I should try also
to put a tenon in here.
And of course, the big problem with that
is that that could cut out some of this
carving.
Do I really want to cut in here on like
the other side and have to redo that
carving? Um, and I don't think so. I
don't want to I want to preserve all
that original carving.
So, right now, my thinking is I'm just
going to redo the previous repair. I
think it was a good job. I don't know
why this broke. It looks like it met
with force. That's a problem with any
chair that doesn't have stretchers. Uh,
all these chairs have been repaired
before. I can see this leg has been
badly broken and repaired. Before I
start working on this leg, while I still
have this piece that fits in there, I
want to uh locate this leg so that when
I go to glue it up, I know where it's
supposed to
end up.
I want to drive a small brad
into the center of each leg.
Now I want this dimension.
And now I'll cut uh three strips of
quarterinch plywood.
Now I want to dimension front to back.
All
right. Now, I just need to I need to get
this dimension.
All right. Well,
this is why I'm doing this now because
I've got my diagonals
dead on.
Yet this leg is crooked.
Now, how can that be?
Well, it's because this is an antique
chair.
I need to figure out where I want to put
this leg. Uh, I cut an extra strip
just for this reason.
I need to come up with its own
dimension.
You can't put a uh square on it. You
can't put a level on it. All you can do
is eyeball it. And that's why I'm
working out these problems right now. I
kind of like where it is right now.
So, I think that this diagonal
needs to be about 7/8 of an inch longer.
All right. I'm liking that. This looks
like it's right where it's supposed to
be. I don't think I need another one
here.
Fire.
You can see that as I get down, you
know, between my saw cuts here, I'm
using a narrower and then a narrower
chisel.
Okay, I'm going to cut a piece of
mahogany to glue in here. Um, just going
through my scraps. Uh this piece is uh I
really there's a lot of different woods
that can be called mahogany. And uh this
piece is very heavy and dense and I just
it just feels like it's going to be a
good strong piece to fit in there.
My block is square but this uh cutout is
not.
So, I want to go in the big sander
and angle this.
That fits good.
Okay, I'm uh
I'm not going to do anything else with
this until I chisel out the rest of that
broken piece and see exactly what we've
got here.
Now, I'm thinking I better pull this
camber back some and uh and maybe I
should try drilling it out as much as I
can.
I'm going to pull back a little bit more
of this fabric. I want to see exactly
uh what we got here.
So, I'm still not sure everything we're
looking at. I mean, this piece and this
piece I assume are the original leg,
although I don't understand that little
crack there. That's a tenon. I don't see
the other tenon, but it might be under
here.
Anyway, I think I'll try to drill that
out.
I'll I'll chisel a little away here to
create a better spot to drill.
I can see a glint of uh metal down in
there. Must be another screw. I don't
see any screws from the inside here. The
screw may be coming in from the outside
underneath the fabric.
Well, I'm just going to keep drilling.
You can see all the bits of metal coming
up.
Well, I got to be getting pretty close
to the top of this leg. I'll start
chiseling now.
Well, I think I've got this uh chiseled
out pretty well. There's a piece of wood
floating down in the bottom. It's kind
of strange. I drilled out a screw and I
thought for sure that and that I would
have to deal with that screw when I
chiseled this out, but I never saw any
more evidence of it. You can see where
somebody's run a couple dowels through
here. But anyway, now I can start to
shape this tenon to fit that.
Leave it a little long.
Heat.
Heat.
Yeah, it looks like I need to take some
off this face here.
Hey,
hey, hey.
I'm getting really close here. I think
though before I do anything else with
this tenon, I'm going to square this up
a little bit. It doesn't look quite as
clean
on this side.
Okay, I think I've got this as clean and
as square as it's going to be. So, and
I'm really close.
Uh, I think now I'm going to take off a
little bit on the sides of uh this new
piece.
So, I've been taking a little off of
here. I go back and take a little bit
more off here and there wherever I can
determine what I think is, you know,
holding up. But it it seems really good
now.
So now I need to do some work on uh the
outside of the leg itself here before I
do the glue up.
Yeah, I'm thinking why not uh get the
touch-ups done before I glue it up or at
least most of the way done.
Off camera, I sprayed a second coat of
shellac. And now I'll sand with the 320.
And then I'm going to tone it.
And I'm using a perfect brown toner.
Okay, let's take a peek.
Nope. Needs more color.
Okay, that dried overnight. Uh, off
camera, I did hit it once more with some
brown mahogany toner, and I think that
brought it in pretty well. And, uh, now
I'm going to spray it with some gloss.
Once this gloss dries, I think we can do
the glue up.
I'm going to use hide glue. I mixed up a
fresh batch of the high strength
granular high glue.
The legs look straight. It looks like
it's where it's supposed to be.
This leg is so tight that uh I don't
need a clamp or anything.
Well,
all right. Let it dry overnight.
Overnight. Okay. This has dried
overnight.
That feels like a rock.
Now, I've already done a touchup, so I
just need to tack this camric back where
it belongs. You know, when I started in
my working in my dad's shop, which was
56 years ago, there was a guy there that
had worked in an upholstery shop. So, he
would do the small upholstery jobs like
this. And how they would do the tacks is
he take a handful of tacks,
pop them in his mouth,
grab a tack,
tack it down.
Now we'll uh
check for level on the table saw.
The legs. The legs look good.
I like it like this as opposed to that.
I like it this. And so I need to take a
little off this uh back leg here.
I think I just need to use my polish rag
on this one. I don't even need to add
any polish to it.
It's funny. When I took the upholstery
tax out of the cup, I was wondering why
there was an discussion pin in there.
Goes right here.
So, there you go. A really nice federal
side chair. It's one of a set of eight
that makes it kind of special. And uh it
had been repaired previously and I don't
think that repair itself failed. I think
this leg must have met with great force
the way it was kind of snapped off. The
piece of wood put in as a repair seemed
fine. The person that put screws into
their repair, but uh and usually a
repair will fail around the screws. Uh,
but I just thought the only thing I
could do was to redo it and uh hope that
it doesn't meet with great force again.
But I think it uh it looks pretty good.
