How Handbells Are Made
How it's made - handbells
Handbells can be seen in church choirs, schools and ringing concerts. There, skilled ringers read music similar to a piano score, playing all the notes found on a modern musical keyboard. Finely crafted and tuned, handbells will continue to entertain generations to come.
Handbells have a long tradition of making beautiful music. From church music to the music of Beethoven.
It all starts with a casting mould that a worker encases in a two-part container or flask. He fills the bottom half of the flask with special coarse sand that's ideal for making sand moulds.
He compacts the sand, and then he turns the metal flask over. He places guide rods onto the bell shapes, and fills the top part of the flask with sand.
He puts a ramming board on again and he compacts the sand that fills the top part of the flask. Now he removes the guide rods. Then he removes the top half of the flask and takes out the casting mould. He re-connects the top of the flask and then frees it completely from the sand mould.
A worker places bronze ingots into a crucible to melt them down. He places heat-sensitive material on to the sand mould, and then heavy weights to hold the mould together safely.
When the melted bronze reaches about twenty two hundred degrees fahrenheit, a worker guides the crucible over to the sand mould, and pours the molten metal into the cavity of the mould. He stops pouring when he sees the heat-sensitive material smoking. This indicates the mould cavity is filled.
Workers then use a vibrating bed and small hammers to free the finished castings from the sand mould.
Rotor blasting cleans the dirty castings. A worker trims off the excess pieces that feed the molten metal into the bell cavity. He sands the sharp edges of the bell, and then drills the central hole for the assembly screw.
The bell casting then goes on a lathe. Here a carbide cutting tool, working with a stylus that follows a template of the bell, removes the coarse casting surface and makes the bell shiny. This turning operation also shapes the bell to give it the right tone.
Another carbide cutting tool shapes the inside of the bell casting, giving it shine, and the desired tuning as well.
Using a custom-made tracing device a worker reproduces the outside shape of the bell on paper. He then traces the inside of the bell casting until he creates an exact replica of the inside and the outside shape. And this must match a master template.
A worker polishes the bell using fine sandpaper. He also puts a jewellers finish on the inside. Then he tests the bell's sound quality using a stroboscopic tuner, and the human ear. He re-sands the bell to make a slight tonal adjustment. Then he tests it again to make sure it strikes the perfect musical note. A worker gives the bell that final polish, and another craftsman engraves the bell for the customer.
Finally a worker puts the ringer (clapper assembly) and bell (casting) together. She puts a washer, a (handguard) disk and a handle onto the assembly screw, and screws it all into place.
Handbells make wonderful music in the hands of skilled ringers, whether the musical compositions are performed by an intimate gathering of friends, or by a concert bell choir of thiteen ringers or more. The music made by traditional handbells is timeless.
