Lever Adjustments
Lever adjustment is something that needs to be done periodically,
usually due to wear (constant engaging/dis-engaging) loose fixing
screw, string wear, or different gauge string re-placement being the
usual reasons.....
Usually it is best to have a service done by the/a Harpmaker but this
is often not practical, if that is the case,some adjustments can be
done by someone who is handy and with a bit of care. The following
is some instances in what can be done.
Loose Lever
This is not much of a problem.....all you will need is a #1 Phillips
screwdriver and your Chromatic Electronic Tuner.

(1) It is best to lay your harp flat on a table, levers up, with the Head
closest to you.
(2) Align the lever parallel to the string and tighten the holding screw.
(3) While the lever is disengaged.....tune the string to its correct pitch.
(4) Engage the lever.....and test the pitch for accuracy.

If when the lever is engaged, the semitone is inaccurate.....you will need
to follow the LEVER ADJUSTMENT section.
Lever Adjustments
(also refer to this when installing levers.)

If your string is correctly pitched when the lever is dis-engaged, but the
semitone when the lever is engaged is in-accurate....then the lever will
need some adjustment.
You will need a #1 Phillips screwdriver, a CHROMATIC Electronic Tuner
and if you need to make a new screwhole:  a small Bradawl.

(1) It is best to lay your harp flat on a table, levers up, with the Head
closest to you.
(2) Align the lever parallel to the string and tighten the holding screw.
(3) While the lever is disengaged.....tune the string to its correct pitch.
(4) Engage the lever.....and test the pitch for accuracy. If when the lever is
engaged, the semitone is inaccurate.....you will need to follow the
continuing  instructions below. (5) onwards.

(5) After following the above.....
While the lever is engaged.....test the pitch with your Chromatic
Tuner....If the pitch is too low, loosen the screw enough so that it can be
moved down minutely (towards the base) within the slot, while
simultaniously plucking the string and observing the pitch on your
tuner.....until correct pitch is observed.
(6) Then hold the lever in place whilst you tighten the screw )making sure
that it is aligned paralell with the string. Thats all there is to it.

If while the lever is engaged, the semitone pitch is too high.....follow the
instructions (5).... but minutely move the lever towards the tuning peg
instead of the base.

Well done.....You are now a Harp Technician
.
Before making any adjustments

There are a number of things that can cause levers to pitch
incorrectly.....
(1) Worn strings....lever engaging and disengaging over time will wear
strings causing the semitone to be inaccurate due to thinning string at
the engaging area...use a magnifying glass to check wear, and replace
string if wear shows.
(2) Lever not aligned paralell with string.....to correct this slightly
loosen the lever, align it to the string , hold it tight whilst re-tightening
screw.
(3) Incorrect string gauge used when re-placing a broken string......
This can cause the semitone pich to be inaccurate.
Remedy: Look very closely at the strings......as the strings go from Low
to High, every second or third string  will be either the same thickness
as the string before it or will be incrementaly thinner, you may need to
check strings with a Dial Micrometer and a makers String Chart.
DENWAR HARPS have String Charts for all their harps on HARP

Installing more levers

If you have already purchased a DENWAR HARP  and wish to add more levers as
you progress.....this can be done with a few tools, a little care,patience and
dexterity of hand....
3 days
BEFORE you attempt installation.... Tune your open strings to the correct
pitches, noting that the Bs & Es should be flattened  (this should be done &
re-done over a period of
3 days, prior to installing levers, so that they stay in that
pitch)
You should now have your string pitches (Octaves, from Red to Red, running up
the strings Low to High.   C, D, Eb, F , G, A, Bb, C .....continuous up the harp.

You will need a #1 Phillips screwdriver, a CHROMATIC Electronic Tuner
and if you need to make a new screwhole:  a small Bradawl.

NOW LETS START INSTALLING
(1) It is best to lay your harp flat on a table, levers up, with the Head closest to
you.
(2)  As you do each string, check it with your Electronic
CHROMATIC Tuner to
see if it is still in pitch.
(3) place a lever (of the correct size) under the string ,with the handle in the
'engaged' position (toward the top of the head)
Gently move the lever Up or Down the string whilst looking at the Tuner, until it is
the correct Semitone pitch (making sure the lever is aligned parallel to the
string....hold it firmly in place and make a hole with a Bradawl centre of the slot
(centred both length & width of the slot....(if you don't centre the width, the lever
will not engage correctly later, and you will have to fill in the hole with a
matchstick and start again)
Place a screw in the hole and tighten it until it
almost holds....
then flip the lever towards the base, check that the lever is centred vertically in the
slot and is parallel to the string, then tighten it fully.
(4) Check with your tuner that the Semitone is correct when engaged.....if it
is...CONGRATULATIONS...you have done it.
If not, you will have to loosen the screw slightly and move it slightly (ever so!)
down towards the base to raise the pitch/ or towards the top of the head to lower
the pitch. (remember: PATIENCE & DEXTERITY)

insight.
