Grandfather Clock Kit is Outfitted a Decorative embossed moving moon dial that is 11x15 1/2 with matching pendulum with a 10 1/2 bob. The "Bob" is the round disk at the bottom of the pendulum.
Includes polished weights, Lyre pendulum, dial, gong assembly hands and hardware. This is everything you need for a clock except for the clock case.
Lyre pendulum comes with either a 6 1/2, 8 1/2, or 10 1/2 inch bob diameters. The "Bob" is the round disk at the bottom of the pendulum. The CM length on the movement will indicate the length of the pendulum from the TOP of the movement all the way down to the bottom of the pendulum nut threads. This is an approximate length that depends on other factors such as bob diameter and weight of the pendulum. Basically if the CM is 94CM the pendulum itself will be about 35 inches tip to tip off of the clock, and the 114CM option would put this same measurement at approximately 44 inches.
Components are installed in this order
The chimeblock will mount to the back of the clock case by the included hardware. It has 12 premounted, pretuned chime rods and an overall length of about 27 inches through the block.
The back of the clock case will only need the four holes drilled to mount this. The bolts have a flat head screw driver slot on the ends, they go through the washer and install from the back of the case to the inside. The washers keep the bolts from going through the wood back and they thread right into the chimeblock. Sometimes it is good to have a spacer block mounted on the inside of the clock case where the chimeblock will mount. Keep in mind that the chime blocks positioning only has to be approximate as the movements hammers are meant to be bent into final position. What this means is it does not have to be dead on, just pretty close to where the movements hammers will be. It should be positioned so the tops of the hammer heads are about 1/2 or 1 inch down from the block that the chimerods come out of. The final adjustment will come later when you bend the hammer wires as to make the head about 1/8 away from the chime rod. This spacing between the head and the rod is so it will not thud or double hit. If you just do each hammer so it sounds good down the line, you will have a nice song at the end.
The cable driven Westminster 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, hand nut and moon dial gear. It has two rectangle shaped outer plates made of brass with the puzzle of gearing between them, and then it has the hammers on the back, 8 on one side for the chime and 4 on the other for the strike.
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 cables and pulleys 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.
3. Moon Dial
Includes a standard sized 11 x 15 1/2 dial that can be used in a grandfather sized case. The silver and brass tone dial has raised numerals. It has a moving moon phase function that works with the included moon drive gear.
1. The Moon Gear.
The first thing is to mount the moon gear to the movement. It will be a single loose gear with a big hole in the center, included with your shipment. Note this gear has a small set screw on the side of it, sometimes two of them. This gear will go over the post that the clocks hour hand will go, and then tightened via the set screw. It may take a couple of tries to get the height correct on this post. What it has to do is mesh with the gearing on the back of the clock dial only.
2. The Selector Switch.
Next 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.
3. The Moon Dial.
Mounting the dial is easy as it has four posts on the back that lock into the movement. Do not touch the dial with your bare hands as you can discolor it. It is best to use gloves or a rag to handle it. Line up the clocks hand shaft to the hole in the center of the dial and then line up the posts with the holes in the movement. At this point the dial is on the clock but it's not secured. There are two ways to secure the dial, one style has locking arms on the back of the front plate of the movement that slide over the end of the dial post to lock it tight. This is if both the dial and the movement are made this way. The other way this is done, there maybe holes in the ends of the dial post feet where an included tapered pin will go through the hole after it's on the movement. Sometimes the dial will be made with the holes in the end of the posts, and sometimes it will just get locked into the movement with the arms.
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 brass tone Lyre pendulum is 44 inches (114cm movement) or 34 inches (94cm movement) from tip to tip off of the clock. This lyre pendulum comes with a polished bob. At the bottom of the pendulum is the rating assembly. This is only a nut and threads that hold the pendulum bob on. It is called the rating nut and threads as it 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.
Do not touch the pendulum with your bare hands as you can discolor it. It is best to use gloves or a rag to handle it. 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 60mm 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.
