fix a loose bar
here what to do:
first of all: do loose the strings tension completely!!
 |
use the iron (wool temperature) to soften the glue that hold the joint between soundboard and side in the zone the bar is loosing. hold it at about 45°, so you do not demage varnish or decorations |
 |
slip in the spatula between soundboard and side. be very careful, and when you meet a bar let the spatula in just the
~2mm of the side thikness you need to open at least 15cm around the loos bar |
 |
moving the spatula (be careful, as ever) do separe the bars (the good ones) from the side and recover the loose bar (it try to stay down) |
 |
you have to have the loose bar to stay exactely in its rigth position, against the soundboard |
 |
push two pins into the bar head (just 4-5mm) right above the side |
 |
with the spatula put some glue (hot) between the bar and the sounboard, then pull a couple of pieces of tape from the sounboard to the side: this, with the two pins in, will act as a clamp to fix the bar to the soundboard |
 |
20-30 minuts later you can take away tape and pins: the bar is fixed. |
 |
let close it up: do prapaire some pices of tape so that you can work fast and easily |
 |
with the brush let some glue (very hot) in, between soundboard and side, then pull the tape to close them up |
 |
do fast them as close as you can. if it take you too much time, use the iron to warm up the glue and pull some more tape. |
|
some few hours later (2-3) everything's ok but, please, do
wait at least 24 hours to take away the tape, to clean up everything and
to tune up the instrument.
