Installation
Read the
instructions!
The installing of planetary
pegs is easier than the customary friction pegs,
provided that the professional
violinmaker reads the instructions before fitting the
first set.
This is how problems can be
avoided: Read the simple instructions.
12-Step Installation Guide
CAUTION:
Installation and removal of the Perfection Pegs should be
carried out by an experienced luthier.
Before installation, please take time to study these
instructions and understand them completely.
Incorrect installation may -
- Necessitate rebushing and/or repair of the peghole
- Cause the pegs to malfunction
- Void the warranty on the pegs
PEG ACTION:
Perfection pegs use a variable-friction mechanism to hold
their internal gears in position against the tension of the
tuned string. In normal use, the degree of friction applied is
controlled by the player exerting a light inward pressure on
the peg head as a string is tuned. Friction is increased by
pressing the peg head inwards as it is rotated, and can be
released to let the peg turn more freely by pulling the peg
head gently outwards during rotation.*
* DO NOT FORCE YOUR PEGS
The application of excessive force pressing in or pulling
out on the peg head while tuning can dislodge the peg from the
peg box.
IMPORTANT: Before you install
There are two types of Perfection peg in each set: pegs for
the treble-side of the instrument and pegs for the
bass-side.
The two types are NOT interchangeable.
If a peg is installed on the wrong side of an instrument it may
not function properly.
The pegs have a fine thread on the shank. Treble-side pegs have
a left-hand thread, while the bass-side pegs have a right-hand
thread.
The pegs are installed on the instrument by screwing them into
the peg holes.
The direction of rotation when screwing the pegs is the same
direction used when loosening the strings.
To determine which way the threads are cut, carefully examine
the pegs and run your thumbnail along the threads to determine
the correct orientation.
The pegs are supplied in a uniform length and must be measured
and trimmed to fit your instrument.
Tools & materials required
- Peg reamer - standard profile
- Marking pen
- Saw - fine tooth
- File - fine-tooth, or belt sander
- Sandpaper - very fine (P220 grade/600 grit)
- Leather patch
- Cotton buds
- Water
- Polyurethane glue (eg. Selleys Urethane Bond)
- Perfection Pegs
| Steps 1 & 2
- Reaming the peg hole |
Step 1 - Preparation & reaming
Prepare the instrument by removing the old
strings and pegs.
Use a standard peg reamer to lightly
ream the peg holes.
|
 |
Step 2 - Test the fit
Test the fit of the peg in the hole.
Ream only enough to allow the pegs to
self-thread very tightly.
|
 |
| Steps 3 to 8 -
Cutting the peg to length |
Step 3 - Initial fit
Select the correct peg for the side of the
instrument on which you are working
(see IMPORTANT:
Before you install).
Screw the peg into the peg hole until no thread
is visible.
Step 4 - Mark the peg length
Mark the peg where it protrudes from the peg
box.
Remove the peg from the peg box.
Keep track of which peg is being prepared for
which peg hole.
|
 |
Step 5 - Cut the peg to length + 2mm
Trim the peg to length with a saw. Cut the
peg end proud of the mark by 2mm to allow for
rounding of the peg end.
|
 |
Step 6 - File the peg end
Round-off the peg end with a file or belt
sander.
|
 |
Step 7 - Sand the end
Smooth-finish the peg end with very fine
sandpaper.
|
 |
Step 8 - Shine the end
Shine the peg end using the leather
patch.
|
 |
| Steps 9 to 12 -
Final Installation |
Step 9 - Moisten the peg hole
Using a cotton-bud, barely moisten the peg
hole with water.
|
 |
Step 10 - Apply glue to the thread
Apply a bead of polyurethane glue (such as
Selleys Urethane Bond) to the threaded contact
area.
|
 |
Step 11 - Screw the peg into the hole
Screw the peg in until the threads are flush
with the peg box*.
The direction of rotation when installing the
pegs is the same direction used when loosening
the strings. The fit should be close enough for
the final turns to be very tight.
As considerable force needs to be used to
complete the last few turns, you can wind a
rubber band around the shank to act as a grip
so that sufficient torque can be applied to the
pegs when screwing them into the peg box.
* Because peg box width can vary widely, the
depth of insertion of the threaded portion of
the peg may have to be adjusted to ensure the
the opposite ends of the pegs are flush with
the opposite cheeks of the peg box.

 |
Step 12 - Clean up & let dry
Wipe off any excess glue. Allow the glue to
dry completely before installing strings.
