"Egyptian" Bow Drills
|
|
The term "Egyptian" bow-drill refers to an
alternate way of winding the string around the spindle. Basically, it
involves winding the string several times around the spindle. This has the
advantage that it spins the drill (spindle) a lot more smoothly, and reduces
wear on the string. As well, the string seems to be less prone to slipping
off the spindle.
Here are two "Egyptian" bow-drills. |

Here is a picture of my "mini bow" with the
"modified tension system", and using the winding familiar to the
Egyptian method.
Using the Egyptian method is easier on the string,
this is true, however there is a problem stabilizing the string.

When you view my second picture, you will see I have
added a "Bows spindle". This is great for this method -- it not only
stabilizes the string, but has a tenancy to even the string as it
rides on itself.

So, using the combined system I have outlined here,
you can, reduce the "bow size", the tension comes from my "modified
tension system" , and we have the advantage of the "bows spindle" to
stabilize the string.
This then gives you more "options" as I always say.
I can choose my spindle sizes easier.
If you use this system, try using 4 wraps -- I find
this to be an optimum.
Here is a final picture. It shows my "bow spindle"
and one can see how nice the string stays in the channel, and my
mini bow with the "modified tension system".
Good luck!
