The correct term for a bola is bola not bolo.
The process of making a cone tip for a bola cord can be challenging
when doing it for the first time.
You might want to make a tip out of a tube the size that would fit
on the cord. Cap the end. Drill two holes in the cap. Make two fobs
that match the Bola. Drill holes in the top of the fobs. Form two u
shape wires. Slip them through the holes in the fobs then slip the
ends of the u shape wire through the holes in the caps. Bend the
ends of the wire that are inside the caps. Epoxy the caps on to the
bola cord. This type of design looks very high end and would
compliment your bola.
note: If the bola tips are heavy they will swing back and forth on
the chest of the bola wearer as they walk. I designed a tie tack
through which the cords slip. The tie tack can then be tacked to the
I made several cap of different designs out of wax and cast them.
Made rubber molds so I can produce them.
I can send pictures of the designs if you contact me off the list.
I am not making bolas now but do have some very nice 6 ply cords
hand made by a friend. They are made with a flat section in the neck
area. They are excellent for heavy bolas. I would be willing to send
you a cord if you contact me off list.
Some bola cords are made with flat leather lacing braided over a 1/4
cord. These cords are very thick. I feel that these cords detract
from the bola.
I am not impressed with the clip designs that have been described on
the list. You mentioned you bola is heavy. All the designs described
will not create enough friction to prevent the bola from slowly
sliding down the cord. It is a real pain to continually slide the
bola up in place.
I used to use what was called the Bennet clip on all my bolas
including the very expensive ones. I never had a complaint about the
use of a commercial bola clip. The commercial clip needed some
polishing to remove sharp edges. I also bent the lower edges outward
so the cord would not get caught in the clip.
I can supply photos of any of the things I described if requested.
