Making a Jingle Bell
written by Bill Clemens - January / February 2007 Hammer & Tong
* Two Bells made by Bill Clemens - large bell is approximately 2 1/2 and smaller one is approximately 1 3/4
I began experimenting with making these bells over a year ago when a how to article appeared in an affiliate newsletter. I quickly discovered that cutting out the bell blank was a stumbling block in making them. I first tried making them from thinner material than called for and found out that they don't form well from thin material. I then cut, ground, and filed one from the right material and was able to complete a bell but wasn't happy with the top half which seemed
to be flat bent petals on a round hemispherical base. I next got a dozen blanks plasma cut at a local metal supply shop that only required some grinding on one side to remove the flash. I subsequently have had blanks laser cut and now after having made several dozen bells think I have the how to down well enough to offer this article to all.
Tools
Top Swedge
Tailer hitch ball or ball bearing with 10-12 inch 1/2 -3/4 stem welded on.
- 2 for large bell
- 1 1/2 for small bell
* Fig. 01:
Bottom Swedge
Pipe with top end flared using horn of anvil
- Large ID ~ 2 3/8 ( 3 inch thick walled pipe)
- Small ID ~ 1 3/4 ( 2 inch pipe )
Add angle iron for use in vise or hardy stem for use on anvil.
* Fig. 02:
Shown below is a quick hardy stem made from flat stock 1/8-1/4 thick and the width of the hardy hole.
* Fig. 03:
The space from the top of the flared pipe to the bottom of the tool needs to allow the bottom of the bell and ring to be inserted. This is a minimum of 2 3/4 for the large bell and 2 1/4 for the small bell.
Bell Blanks
Cut (or have cut) bell blanks using the templates at the end of this article. Use 3/16” (or 7 Gage) for the large bell and 1/8” (or 11 Gage) for the small bell. Make a
center punch hole on the inside of the blank for drilling the stem hole and touch mark the blank on the outside.
* Fig. 06:
You may also decorate the outside of the bell at this point, such as adding leaf veining to each of the 4 petals of the bell as shown here:
* Fig. 07:
Dish each of the petals of the bell blank using a spoon swedge and ball pein hammer.
* Fig. 08:
Form Bell – Heat the blank uniformly to a yellow heat and begin sinking it into bottom pipe swedge with the top ball swedge. This will take several heats as you are upsetting the material between the bell’s petals.
* Fig. 09:
To help shape the bell use the top ball swedge on the anvil to smooth out and round the portion of the bell being upset between the petals.
* Fig. 10:
Continue sinking the bell until the ball swedge can just be removed from the bell.
* Fig. 11:
Use the smaller ball swedge on the large bell or a 3/4 inch rounded end rod on the small bell to round out the area between the petals into a ladle swedge block.
* Fig. 12:
Stem – Drill 1/4” hole in bottom of bell to accept stem
* Fig. 13:
Forge stem from 6 inches of 1/4 inch round. Head one end and taper 1 1/2 inches of other end to a blunt taper.
* Fig. 14:
Heat the headed end of the stem and insert in
the bell bending the stem at approx 90 degrees
close to the bell.
* Fig. 15:
Heat and flux the stem head and then wrap
with copper wire. Preheat the bell and then
reinsert the stem. Heat slowly to near welding
heat watching until the copper wire melts.
* Fig. 16:
Remove from forge and hold head in place
until bell cools and copper hardens.
* Fig. 17:
Heat stem and form ring with scrolling tongs.
Take care not to overheat the bell and break
the copper braze.
* Fig. 18:
Heat tapered end and wrap around stem with
scrolling tongs to finish ring.
* Fig. 19:
Place bell in forge with petals down and heat
to bright orange. Set bell in pipe swedge, insert
ball bearing (3/8 to 7/16” for small bell 1/2 to
5/8” for large bell) Hammer petals closed with
gentle blows near their base.
* Fig. 20:
Space petals with thin tapered chisel/fuller
while using a hammer to close them.
* Fig. 21:
Completed bell has a bulge where the metal
has been upset between the petals and the
hole at the end of the slots is not round but flat
on the bottom. You may choose to leave the
bell like this or remove it. It does not seem to
have much effect on the sound of the bell.
First file or grind the bulge flush following the
contours of the bell. Next, with a round file or
die grinder, round the bottom of the hole.
The bell should be heated again to critical temperature(non-magnetic) and quenched to improve it's ring.
Options for the bells include using a nut and bolt in place of the ring to fasten the bell(s) to a leather strap. You could also drill and tap the base of the bell to accept a bolt for this same purpose.
