damper liftrods

[Joe And Penny Goss]

Hi Eliot,
The aluminum frame (rail) could be warped
or bowed.
You might be lucky and be able to straighten the frame.
A few years ago I had the same story with a Yamaha that had been body
slammed.
I ordered a new main frame and went to the school to install only to find
that the new frame was also bent almost as badly as the old rail.
If my memory is correct, I placed a screw driver blade from my combination
kit under the rail and bent the rail back straight enough to use the old
rail and then sent the new one back.
To make the repair I had to remove everything from the rail.
On the Yamaha there is a support screw that is an adjustment to keep the
action
from bending towards the strings.  The support screw was so badly bent that
it had to be replaced.
