Bow Rehairing Steps

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
  7. Clean the stick
  8. If necessary adjust how snug the frog fits on the stick
  9. Carefully remove the ferrule ring
  10. Remove the slide
  11. Lubricate the slide slot with a pencil so it's easier to remove the next time.
  12. Remove the block.
  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.
  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.
