Posted: Tue Sep 25, 2007 12:12 am Post subject: Bow rehair question |
|
|
In a bow rehair, what should you do to ensure that the length (thus the tension) of the bow hair is even across the width?
I always end up with the hair at both side of the ribbon of hair slightly longer than those at the centre. How to avoid this? |

bttay... now that used to be my million dollar question...and I have never been really satisfied with the complete traditional approach!
This is what works for me to perfection every time!
1- I always rehair from tip first then frog. Comb it well!!
2- I use 28 ga brass wire to tie the knot while dry.. If you tie while the hair is wet it will shrink when dry and then the knot will not be as tight as possible
3- I use "Sealall" adhesive that positively will not release the hair from a knot
4-I do not like the alcohol lamp which is used to shrink the longer hairs. With the flame, even the hair that does not need shrinking will get shrunk... I use an inverted dry iron set at high... the long sagging hairs are set onto the plate and ...presto they pop right into place!
5- If you are adventurous, then try stretching the short hair before you shrink the long!
6-I NEVER rehair quickly... always one careful step at a time ... 3 days at least total.
To answer your question... shrink the hair on both sides.
looking forward to some commentary from the others!!
BTW, I will be off he forum as of friday for about 10 days...
good luck!

Hi Mat,
Thank you for your valuable suggestions. The inverted iron method sounds great. Will try that.
Do you mean that you tie both ends of the bow hair dry?
Would you mind telling me what is the advantage of rehairing from tip rather than from frog? |

Day 1- clean frog, shaft, mortises & inspect for any repairs that may be necessary. Tie one end of hank, glue knot and let dry overnight.
Day 2- Wedge knot into tip and comb & tie frog end knot...glue knot and let dry overnight
Day 3- Wedge knot into frog mortise, finish with ferrule wedge. Wet & tension hair, let dry, tighten loose hairs.
Day 4- check and make final adjustments, call Customer with good news!
Overall, I guess I spend about an hour or more per bow.
Keep in mind I work full time, so I have only evenings to work on these things.... and I spend more time fussing than necessary! My price is $55 using the best grade siberian hair.... less discounts for any of the musical equipment retailers
Cheers, Mat |

Yes I tie both ends dry... much better than wet.
Ending the rehair process at the frog gives a definite advantage in that there is more room under the slide to comb and hide any last crossover hairs behind the ferrule wedge.
Cheers, Mat |
