Fabricate bell hammers and springs - April 2014
These six photos show the fabrication of the three bell hammers.
First a hole is drilled through the cylindrical blank. Then a concave form is
cut into the blank. Next a fly cutter is used to make the pattern on the concave
Here a collar is fitted into the hole through which the hammer
lever will pass through.
Here we have the hammer levers and the completed hammer head.
Note the contour on the lever edges. Each hammer head is fitted with a hardened
leather insert. The screw used to secure the head to the lever is hidden behind
the leather insert so it remains invisible.
Next the spiral springs needed to load the hammers are
created. Without them the hammers would pull away from the bells since the
balance of the lever work is heavier than the small hammer head.
