Here are the general steps to rehair a bow. Violin bows are still $ 22 if you leave them for one week. I can do them sooner if needed but I charge a little extra. This one week service allows me to spread out the amount of rehairs I do so that it's more manageable.

1. Inspect the stick
2. Cut out the hair leaving about 4 inches at each end
3. Clean the metal of the frog and the button
4. Clean the winding
5. Glue the thumb grip if it's loose
6. Remove the tip block
   • Usually the block can be wiggled out, but care needs to be taken because the tip mortice is delicate.
   • If the block is stuck carefully drill a small hole in it's center and whittle away the block from the center out. More Info
7. Clean the stick
8. If necessary adjust how snug the frog fits on the stick
9. Carefully remove the ferrule ring
   • If it's too tight, keep pulling the hairs out until the wedge is loose
10. Remove the slide
    • If the slide is stuck, putting a little rosin dust on your thumb might give enough friction to push the slide out
    • If the slide has been glued in it can be removed by injecting a little water under the slide and carefully applying a little heat. More Info
11. Lubricate the slide slot with a pencil so it's easier to remove the next time.
12. Remove the block from the frog.
    • If the block is stuck, drill a small hole in the center and whittle it away. More Info
13. Cut the block for the frog's mortise, matching the length of the block mortise minus the thickness of the hair. Most of the time if I rehaired it last time I can reuse the block.
14. Select the correct amount of horse hair for the bow
15. Tie the hair very tightly with very strong cotton blend thread using the correct length for the block mortise hole
16. Cut the hair and tap the end into some crushed rosin
17. Burn the end of the hair
18. Put the hair into the block mortise hole so that it's flat and snug in the mortise
19. Put crushed rosin on the end of the block.
20. Push the block into the block mortise hole.
21. The hair will be flipped over the block. It should fit very snugly. Give a little pull on the hair to make sure the block does not move.
    • If necessary, you can make a final adjustment to the amount of hair by cutting a few hairs out next to the block
22. Replace the slide into the slots on the frog.
23. Replace the ferrule ring.
24. Make a new wedge. Some people reuse wedges but most of the time they will not fit correctly, so I always make a new wedge
25. Spread the hair across the ring and test the wedge. It should fit tightly and keep the hair evenly spaced
26. Next measure how far the frog need to be back from the grip.
27. Make the tip block
28. Comb the hair so that the comb runs smoothly through the hair
29. Wet the hair but don't let water get next to the wedge
30. Comb the hair and keep an even pressure
31. Hold the hair with one hand and tie the hair just after the tip block mortise.
32. Once the correct hair length is set, finish tying to the knot to correct length using a very strong cotton blend thread
33. Cut the hair after the cotton blend tied knot
34. Tamp the end of the hair into crushed rosin and then burn the ends of the horse hair.
35. The width of the tie should allow the hair to get pushed into the tip block hole but be snug.
36. Comb the hair again using an even amount of pressure
37. Hold the hair between your fingers keeping the hair even.
38. Flip the hair over and put the tied end into the block mortise
39. Put rosin on the end of the block and push it in over the hair
40. The hair should be even
41. Lubricate the bow screw
42. Flip the hair back over and replace the frog
43. Tighten up the hair a little
44. At this point if needed, the hair can be adjusted slightly
45. Keep the bow at a little bit of tension while the hair is drying. Do not allow water to wick into the wedge
46. After about an hour adjust the tension again on the stick because as hair dries it gets a little shorter
47. After the hair is dry, apply powdered rosin to violin, viola and cello bows. I don't rosin bass bows.
