Urgos Chime Movement - Mainspring End Repair

In for repair is a Westminster Chime mantle clock.  The customer stated that the clock does not strike the hour otherwise the clock runs fine.

The strike winding arbor does turn but would never feel like the spring was getting wound.  There is only one reason for this; The mainspring is broken.

Here is a picture of the movement out of the clock:

The clock movement was taken apart.  The mainspring was removed from the barrel.  The mainspring end was broken.  Fortunately, this can be repaired.  A new mainspring does not have to be acquired.

Here is a picture of the barrel with a piece of the mainspring attached to the barrel pin:
And the mainspring:
Like with haircuts, you can't grow it back.  The only way to repair this is to cut the damaged hole out and reshape a new end.  The picture below is the finished product:
The clock movement was inspected for wear, pivots checked, clicks checked, mainsprings checked to see if they were set.  All were OK.  The movement was cleaned, reassembled, oiled, and adjusted.
