The self-taught clockmaker details the process of restoring a nonworking grandfather clock. The 200-year-old heirloom, damaged by age and insects throughout generations of use, came to the United States from England.
Hi, I'm Devin. Today I'm going to walk you through how I restore a 200-year-old grandfather clock.
Clocks that old weren't branded with anything other than just the clockmaker's name. A single
person built the entire thing. This particular one is Abraham Shaw of Billingborough. So,
an English clock. My customer brought it from England to the U.S. She inherited this from her
parents, who inherited it from their parents, who inherited it from their parents back to
ballpark 1820s. Pre-restoration, this clock is probably not worth much. I'd say maybe $500 at
most, probably less. The case definitely is in the need of more attention than the mechanism.
The whole case has come apart. I like to start with the cleaning just to make sure there's not
going to be any kind of dust or debris or, with all clocks, spider webs. It's going to be in the
of, you know, re-gluing everything. The next step after I clean it is start approaching some of the
wood repairs. I almost never have to fix a case this bad of tradition. This case was
in serious need of help. The parts of a clock case, the names of them vary. Each country would
call them different things, but typically for an English clock, you would have the bonnet,
which is the hood, basically just slides off. It has the front door to it and then typically some
type of decoration to make the clock look nice. Then you have the trunk, which is just the main
body of the clock, where you have a door. You can see the pendulum and the weights.
The base of the clock is the bottom square section. The floor of the clock was broken
and half of it missing, so I just do a couple quick measurements on the inside and cut out a
piece. This is the most common broken thing on grandfather clocks. If there's some type
of failure from the weights, the weights come crashing down and when you get a 200-year-old
clock, chances are it's missing the bottom. So I attach the floor to the base by using
glue and nails, and then the nails just help the glue dry properly. The top right trim piece
of the hood is often in very bad condition. I was left with decisions to make there,
and I just decided to keep the original piece. It was a little difficult to tell what was actually
the cause of that top corner, but my best guess and a few other clockmakers that gave me an idea
was most likely bugs of some sort and that it got rotted from there. The first thing I needed to do
was copy its profile. There was no good place to copy it on this piece because it was damaged
pretty much all over. So I just went to the back edge of the other side and just used a piece of
paper and a pencil, and I just get the profile for that piece. Then I glue that to another piece of
wood to cut that shape out, and that piece of wood is what we will end up calling a form tool.
Then I use a combination of Bondo wood filler and paint just to get it close to the right
color initially. Of course this clock would have been stained originally, so to try to match that
look I just used a combination of brown, red, and black paint to mimic the wood grain as best I
could. I mix that up with the hardener and apply it on in large copious amounts onto the piece,
and make sure it's all rubbed into all the nooks and crannies so it's going to make a good joint
everywhere. Then I use that form tool that I made to basically wipe off the excess other than
where I want it. I wouldn't call it fabrication, but I did have to, for lack of better terms, fabricate
that piece. Then I cut it off to size so I give it a 45 degree angle on the front where it
will meet the other piece, and then cut the back off just straight where it will be at the back of
the clock. Then I glue it down. In this case I did not use wood glue because I used Bondo
wood filler, and I didn't want the wood filler to make it so the joint would not be strong.
So I used a general purpose glue everything type of glue, which I wouldn't use on something load
bearing, but this is just an ornate decorative piece on the side, so that glue will be sufficient
for that. Nine times out of ten, wood glue is going to be your best option. There's a lot of
odd shapes on on this, so it's not easy to clamp. Clamps have to be opposite from each other, and
you don't always have that availability, so I usually use weights or something like that in
place. Easily the hardest part of this case, easily the hardest part, was the glass. That
could have been glazed in place 200 years ago, and then at some point during its life,
that glass broke, so I'm left with a bunch of glazing that's full of glass shards all throughout
it. So there's no great way to get that old glazing out. The method I use is just take a
razor blade and scrape it out. You know, take your time going around the whole perimeter,
clean up as you go to make sure none of the glass shards are going to hurt the piece of wood.
Removing that previous glazing is very tedious and can hurt you. And then I put the glass in,
and then I use a couple nails to hold the glass in while I glaze it, and it's straightforward,
but definitely requires a steady hand. I, in between, do work on the mechanism, so
you know, disassemble it. Disassembly takes a lot of focus. You have to make sure you're paying
attention to where things are, if you see any kind of previous repairs, because previous repairs are
usually a sign of disaster. A lot of beginner clockmakers or hobbyists are tempted to not
disassemble the movement and dunk it straight into the ultrasonic cleaner, thinking that it'll
clean it, you know, it's in there. But you do need to take everything apart, not as much for
cleaning, but more so for rinsing and drying afterwards. The solution will go in between
the little tiny parts if they're still together, and they won't, it won't come back out when you,
when you try to rinse it. You got to take the everything apart down to the very last screw,
very last pin, and clean it that way in the ultrasonic solution, which needs to be clock
cleaning solution. If it's just brass cleaning solution or something along those lines,
you can flash rust the steel, or if you use steel cleaning solution, you can actually corrode the
brass. It sits there for ballpark 20 minutes. That solution stays on the parts too long,
it will ruin them. So you have to very, very thoroughly rinse it all off with water,
and then water is just as bad as the solution if you don't dry it off. If even a little bit of
water stays stuck in a corner, it'll destroy the clock in a matter of a couple years.
Now I'm gonna repair the mechanism. I start working on the pendulum. The pendulum was
already at pieces when I received it. The bob of the pendulum, the brass circle at the bottom,
is actually how we determine how fast or slow a clock will run. So it needs to be able to slide
up and down smoothly without any kind of snagging or getting stuck. So I had to remove a very small
amount of material from the rod to make sure the bob could go up and down, and then polish that
surface to make sure it's as close to frictionless as possible. I actually found some witness marks
on this particular clock. On the rod, there were some lines scratched, and I just went ahead and
assumed that that's where they wanted the pendulum bob set to. So I went ahead and set it right there,
and put the screw on underneath it, and it actually worked first try. So that witness
mark was correct. Next, I am polishing the pivots. I'm not focusing on the gear, I'm actually focusing
on the arbors for the gears. At the end of each arbor, there is a pivot point that it will turn
inside the plates. It's axle, basically. Clock parts have a lot of terminology that don't match
up with today. Gears are not called gears, they're called wheels. Axles are not called axles, they're
called arbors. I use a lathe, which is convenient because it turns everything concentrically.
It makes everything a lot easier, and turns out nicer in the end. A lathe is actively trying to
kill you at all times. If you touch it, it will not stop. So I keep my fingers out of the way by
using paper, and then if I have enough room, I actually use very fine abrasive stones, like an
Arkansas stone, which is just very fine, fine grit. We're talking around like 4,000 grit.
If you leave jagged edges, it doesn't happen overnight, but over the course of a few years,
the clock will actually eat itself away if it's not smooth, smooth surfaces. The other end of them
is their bearings inside the plates, the little holes in the plates. Those need the same process.
They need to be cleaned very thoroughly, and then, you know, made sure that they're polished properly,
where it'll have very little friction. The escapement pallet is going to be one of the
most ignored things in a clock, but arguably the most important. This is what the pendulum is
attached to at the very top. That groove, that's a fraction of the thickness of a human hair.
It's really, really small. The escape wheel has been hitting that over and over again for many,
many years. The clock will not run accurately if those grooves are there. Most people, when they
repair clocks, will ignore this, but I go ahead and repolish those surfaces. We're putting in brass
cable. When I picked it up, it already had brass wire, but originally, it would have had catgut
cable, which would have been made out of catguts. That's exactly what it sounds like. We use brass
instead of steel, because steel cable will actually tear up the parts inside the clock,
but brass is what the parts are made out of, so it's hard to tear up brass with brass. You want
this to wrap around the barrel that it's going onto the correct amount of times, and you also
want it to have the weights reach the bottom of the case in eight days. This is an eight-day movement.
There's a few things you've got to be careful of when assembling the mechanism, so the obvious
one is to make sure everything's in the right place, but that's actually a lot less like a
does. It only has one place to go, and then the difficult part is indexing it, where you don't
just put it in the right spot, but it needs to be oriented correctly when it goes there,
so you need to have one part of a gear meshing with another part of the gear.
All those pivots that we polished are very fragile, so when you are putting plates together,
you have to be very careful and use very small amounts of force to try to nudge everything
into its place and make sure that the pivots go into the correct holes and aren't damaged.
That's definitely the art of fixing the clock, is trying to close the plates. It takes a certain
feel. Once it's together, then you get it up on the test stand and make sure it's still working
right, and then there's actually a several-week period of testing. Every time I come into the
shop, I see if it's running fast or slow and make an adjustment. Usually, when I test it there,
I like to get it to where everything is working completely properly for a whole week straight.
Then I put it into the case to test it there to make sure it's all going to continue to
work properly. Time at the workbench, I spent probably around two weeks or so
actually working on stuff. I'm talking full hours of two weeks.
I'm pretty happy with this restoration. Definitely the movement. The movement was,
you know, everything went according to plan, how I liked. The most satisfying part of this
restoration and every restoration is definitely going to be one of two things. Either
the first time the clock ticks, you know, when I set it up and it works. That's extremely
satisfying to have that happen. And the other part is the client. When I deliver it back,
it's extremely satisfying to see these people's reactions, you know.
Sometimes for clocks that are chiming clocks, I'll bring it back and they haven't heard it
chime since they were eight years old in their grandparents' house. You're only the temporary
caretaker of this clock. It's been around for 200 years, you know, it's going to outlive you,
so it's more important to do what is right for the clock. I try to keep it original
as much as I possibly can at Old Tucker's.
