Often the rods are pressed into the block by machines and is difficult or next to impossible to get a single rod out or replace it.Read More »
Other times they are screwed in but again this is done by a machine and is very difficult to remove. Also there are various threads on the rods that are the replacements, it is a tricky thing to get the correct thread size for the individual chime rod and have it fit perfect. Very often the chime rod ordered is returned and swapped out a few times and then just giving up on the individual chime rod and going with the complete chimeblock with the rods anyway.
So with all this we do not sell the individual rods that go into the block, but rather the entire block and rods together as one unit.
The first step is to determine what style chime block is needed. This is where the hammers are located on the clock movement itself.Read More »
There are either side, bottom and back strike style clock movements. Chime block style A is for the bottom strike units, and also can be used on the side strike units as well.
The style B is for the side strike units or in some situations the back strike diagonal style Westminster units.
The style C is for floor clock models (and in rare occasions wall clock styles) with two rows of hammers on the back of the clock movement.
With the style clock chime block decided the next step is to count how many rods are needed, and the length off the longest rod measuring through the chime block. Find this information on the corresponding drop down list for the style chime block needed.
The hammers are on wires as they are meant to be bent about an eighth of an inch from the chime rods. Read More »
It is not uncommon to have to bend them up to an inch and a half for this, in the forward, backward, left, or right directions.
At the 1/8 inch distance, ideally they will not double hit the rod, or make a dull thud, or miss it completely. When installing a new chime block, it is not uncommon to have to adjust and bend the hammers on the clock movement to strike the chime block's rods from the correct distance.
Select # of rods / length

4 3/4 diameter with a brass end. This includes the mounting base. This is for a back mount coil gong strike movement such as a wall clock.
These are the chimeblock mounts and washers to mount the chimeblock to the clock case. The chimeblock has threaded holes usually and these screws go through the case and into the chimeblock.
