Bell Strike Clock Kit
This quality chain driven Bell clock kit will strike the hours on a nice deep sounding bell, and then strike once for the half hour.
This is a great clock kit for a small shaker style grandmother or granddaughter sized clock case.
Here are some measurements you need to know to build your case, but of course the best thing to do is to get the movement first and then build the case afterward.
The two weight chain drive and the bell makes this simplistic clock kit would make a nice smaller sized floor clock. The Tempus Fugit dials hump top can be easily zipped off for a 11 x 11 dial instead, if needed.
The kit comes with the movement, bell, the dial, pendulum, and hands. This is a complete clock with out the wood case
Components are installed in this order
The Bell is 5 inches in diameter and is cast brass.
You can bolt the bell anywhere in the top of the case you would like. The strike hammer on the movement is very long, so it can be shortened to whatever length will hit the bell where you mounted it. The hammer head on the strike wire is only on with a set screw so after the rod is cut, you can slide it on at any position. The hammer should strike the bell somewhere close to the outer edge. The hammer should be about 1/8 inch away from the bell at rest for the best sound. If its less or more it will thud or double hit usually.
The chain driven Bell Strike movement will run 8 days on a single wind up. It comes factory oiled and ready for installation. It includes its chains, mounting screws and washers, the leader, the suspension spring, and hand nut. It has two square shaped outer plates made of brass with the puzzle of gearing between them, and then it has the hammers on the top for the bell. The hand shaft, (shaft that the hands go on) is 27.2mm from the front plate and all the way out.
The movement will need a seat board to mount on. A seat board can consist of only two parallel board strips that are approximately 2 x 2 square. These two boards run along the bottom of the hood of the case, spaced about 1 inch apart. The front plate of the movement sits on one board while the back plate sits on the other. The chains drop down between the boards to suspend the movement in the air where everything else will dangle from it. The movement is secured from underneath with the included two screws and rectangle washers. The washers are rectangle as it will clamp each seat board while the screw goes up to the movements bottom pillar post's threaded hole.
Includes a Tempus Fugit style dial that is 11 x 14 7/8. The silver and brass tone dial has raised numerals.
The first thing to do is install the selector switch to turn off the chimes to the clock. Find the small steel arm that is about 1 1/2 inches in length with a set screw. This will go on the arm coming out of the clock movements right hand side. That is to say, your right as you face the front of the clock movement there is an arm sticking out the movement. The selector arm gets put on by sliding over that larger arm and secured with the set screw. It may or may not already be mounted on the movement, but if it is not, it only needs to be able to come through the slot at 3 o'clock. This will enable the customer to change the chime to silent.
Mounting the dial is easy as it only has to be attached to the wood case. The usual way this is done is drilling four pilot holes in the corners of the dial and use some small brass screws to secure it.
4. Hour and Minute Hands
Black Serpentine style hour and minute hands sized for the dial diameter.
The hour hand has a round hole and is only a friction fit onto the post. It will be able to move forward or backward to adjust the time. The minute hand has a 2mm square hole in the rotatable mounting bushing. The minute hand is secured with the included minute hand nut. If the clock ends up chiming at other times than the quarters, do the following. Take the minute hand off of the clock, this is the longer of the two hands. With this minute hand off of the clock, turn it upside down, you will see it has a square hole where it attaches to the clock. Well this square hole is in a bushing that will rotate WITHIN the minute hand itself. So just use needle nose pliers to turn this bushing so the square in the bushing rotates. Then put the hand back on the clock and see if it is pointing to the correct place where it chimed. Then set to time.
The wood stick pendulum will come unstained so it can be stained like the case on the customers end. It is a simple design that is good for the rustic antique style look. The pendulum length on this unit is measured from the top of the clock movements suspension post and all the way down. This measurement is 75cm and includes the pendulum tip to tip, the leader it hangs on, and the suspension that the leader hangs on.
The wood stick style pendulum will include the bob included separate in the packaging. The bob will need to be mounted to the bottom of the sticks rating nut threads, with the nut on the threads to secure it. This is called the rating assembly and it holds the pendulum bob on and is used to adjust the time keeping of the clock. If you turn the nut at the bottom as to raise the pendulum bob a little, this will speed up time. Reverse for slowing of time.
After the movement is in, its only a matter of hanging the pendulum on its leader. The term leader is that pendulum hanger on the back of the movement that swings back and forth. Be gentle with the pendulum and leader, no violent moves, just hang it on there and then stop the pendulum from wobbling around.
The kit includes three polished brass tone weights that are 47mm in diameter. The weights are shipped complete with fillers already assembled. Please note, these are tricky to ship as upon shifting back and forth sometimes the end caps get slightly damaged or concave. If this is the situation just let us know and we will ship out new end caps free of charge.
Do not touch the weights with your bare hands as you can discolor them. It is best to use gloves or a rag to handle them. These weights may or may not all weigh the same, usually they do not. If they do not, the heaviest weight goes on your right as you face the clock. Out of the two that are left, if there is one lighter weight, this will go on your left as you face the clock. The reason for the inconsistency of the weight specifications is due to factors such as pendulum bob diameter and also the weights function. To hang the weights on is easy, there are three chains with the clock that loop over there sprockets in the movement. Just hang the weight on the side of the chain that has the hook on it, and then stop it from wobbling around.
