Sand/file the metal to roughen it. Then wet with unthickened epoxy. Then =
sand the wet epoxy into the metal with 80 grit paper. Then apply epoxy =
thickened with high-strength bonding filler. Strong as steel.

Hi Terry,
I am surprised, you were able to get a good bond with the epoxy, on =
the metal to metal. I thought epoxy needed some roughness?
I usually solder, although, I think siver solder would be better.
Kawai, will send you the pins, after the first one, I got some spares. =
As to be expected, non have gone since.

Subject: Vertical Damper Lift Rail
I repaired a vertical damper lift rail the other day. Typical thing =
where one of three little steel L-shaped hookies that pivots in a flange =
broke off. I just made the appointment to re-install the rail and the =
guy asked me what the charge was. I told him. He didn't sound happy at =
all. I am expecting..... shall we say a difference of opinions? My =
question (before I tell what my charge is/was) is how much time would =
you charge at your normal hourly rate for such a repair?
I'm in Florida and rates are pretty consistent here with most of the =
mid-west. I typically charge $60 an hour for on-site service work and =
$50 an hour for shop work. And I think I gave him a good deal =
actually.......
The piano is a recent model Kawai.
The tasks I had to do:
1 - diagnose problem (pretty fast on that one)
2 - remove action
3 - remove damper rail
4 - replace action
(I tuned the piano at this first visit - so no need to charge for a =
service call specifically to remove the damper rail.)
5 - repair rail (make new L-shaped pin, drill hole in rod, epoxy pin =
in place)
6 - service call to remove action, install rail, re-install action =
(25-mile round trip - I wasn't scheduled to go out that way for two =
weeks and the girl that plays the piano is active on the piano and so =
she wanted it back together ASAP - so this was a special service call to =
that area.)
Thanks for any input.
