How to Build Your Own Wall Clock

How to Build Your Own Wall Clock

Five parts, clock motor, hour and minute hands,
clock dial & wall hanger. Making a wall clock with a quartz clock movement can be amazingly
simple. These battery clock movements allow you to make a very functional accurate timepiece,
without much effort. You will need a piece of stiff dial backing
material that you are going to glue an 11-1/8” clock dial to. It could be a piece of plywood,
In this case we used masonite. Just cut the material about 12-13
inches wide so that there is a small border around the 11-1/8 clock dial.
Measure how thick your material is. If it’s ¼”, then get the MVT7160A or MVT7190A clock
movement. If it’s thicker, than just choose a movement with a threaded shaft that is 1/8”
longer than the material thickness. The threaded shaft has to go through this backing material
as well as the 11-1/8” clock dial with about 1/8 of an inch to spare.
You will need to drill a 3/8 inch diameter in your backing material to allow the movement
shaft to go through. Be careful to get the exact center of your circle marked correctly,
Here we are using a compass and a ruler to determine the exact center.
Next you will want to finish your dial backing material as desired. Here we used masonite
and have puttied and sanded the edges. Then we sprayed on a quick coat of primer, then
when dry, some black spray paint on just the edges.
Once the 3/8” center hole is drilled and the paint is dry, it’s time to mount the
clock face to the backer material. There are 2 methods I use. The easiest is to use a role
of thin double faced tape. Place 3-4 small pieces around the center hole, and maybe 10
small pieces around the outside edge of the clock face. A piece ¾ to 1 inch long works
just fine. The best way to mount a clock face to a backer
material is a contact adhesive. It’s applied to the back of the clock face and carefully
on the front of the backer material. Once dried and carefully installed it will give
you the best possible bond. Whichever way you have chosen to mount the
clock face, you will probably find that having something to align the center of the backer
material and the clock face is very helpful. I normally hold the backer material up in
the air a bit by using a few scraps of wood. I place an unsharpened pencil in the mounting
hole. Often, I have to use some masking tape wrapped around the pencil to get the hole
size right. If you had a piece of a 5/16 inch dowel rod cut to 4-5 inches long it would
be perfect. Carefully slide the adhesive backed clock
face over the pencil and slide into place. Make sure you have the “hole” centered
as best you can. Press the clock face in place by use a soft cloth to smooth out the clock
face from the center, then going out to the edge.
Now, it’s time to install the clock movement and clock hands. The only tool you might need
is a pair of needle nosed pliers. Install the steel wall hanging bracket over the movement’s
hand shaft. Then place the small black rubber washer over the hand shaft next.
Slide the clock movement hand shaft through the 3/8” center mounting hole. Now, slide
the small round brass washer over the hand shaft. Carefully thread the brass hex nut
onto the larger threaded part of the shaft. Tighten the hex nut as tight as you can with
just your fingers. If the movement can be turned, then tighten 1/8 to ¼ of a turn.
Do not over tighten this nut. It could cause the movement to run slowly.
Time to install the clock hands. Try to work in a well-lighted area, and grab your reading
glasses if you need them. Just to review, the hour hand is the short one and the minute
hand is the long one. Take the shorter hour hand and press it firmly onto the Nylon hour
hand shaft. Do not press on so far that the hour hand actually touches the threaded metal
shaft below it. The minute hand does not have a round hole.
It’s oblong with 2 flat sides. Make sure you line up the flat sides of the minute hand
with the flat sides of the metal minute hand shaft. Press the minute hand on the metal
minute shaft. A slight “wiggling” may be required. Once the minute hand is on, carefully
thread the minute hand cap nut onto the end of the shaft.
You’re almost done. Just use your fingers to move both of the hands to the 12:00 position.
Then use the time setting knob on the back of the clock movement to adjust to the present
time. Install a AA battery in the correct position and you are done! Hang it on a wall.
