Capo bar revisited

[llafargue]

Don, Alan, et al,
I ordered the #5050 back during our last discussion and filed the first
section on the B in question, jumped through all hoops, repositioning
the strings, seating everything, leveling strings, fitting
hammers/strings, etc, etc, and while the sound improved, the problem
still existed on a few notes and the piano is being returned.  I, in
effect, failed in my attempt with this file.  My radius appeared similar
to the original, no measurements were made. And before I did the work
the bar was very rough, pitted and had some paint touching at some
string terminations, so I felt I could improve it.  But, I now wonder
about front duplex and string angle going down to that V and the length
of that front duplex length and it's affect.  I don't want to beat a
dead horse, but I am still on a quest for a cure.  If anyone buys a file
or finds a cure/formula I am all ears.  My efforts on this particular
piano with that particular file were, for the most part, unsuccessful.
Thanks.  

P.S.  I have been eyeing Mason & Hamlins with the V across half of the
scale and notice major differences in design and wonder again about
their front duplex termination materials, lengths, angles and such.

Thanks Don,

I also emailed them to ask about the radius of the files in question
(they
never responded to phone calls). They answered that the radii were
0.250"
and 0.187".  As these didn't seem reasonable to me, I bagged the idea.
Thanks for pursuing this. Please let us know what you think of the 4456
file. I like the fact that it has both grits.

List,

In the January issue of the PTG Journal there is a O& A discussion
regarding
the capo bar. On page 20 there is a response from me regarding the
capo/fret
file that Bill Spurlock used to sell. I mentioned that the file is still
available from Stewart-MacDonald. That is not the case.
When I called the company the first time, I was told the file is still
available. Since I wanted another one with the 150 grit, I placed an
order.
When I received the file, it was not the same file as the one Bill sold.
(The file on the left of the photo - page 20 - is the one Bill sold)
When I
called Stewart-MacDonald about this problem I found someone more
knowledgeable about their inventory. The type of file that Bill used to
sell
has been discontinued for some time.

The problem with the similar files involves the radius. It is too narrow
in
my opinion for capos or duplex bearing bars. This includes all the
catalog
numbers that Lance Lafargue mentioned in the next response on page 20.
Stewart-MacDonald does have a different file that holds some promise for
capo filing. Their "Dual Grit Diamond File," catalog number
4456 should work well. I have since ordered this file but I have not had
the
opportunity to try it out. You can have a look at this file at the
following
link:

ing,
_polishing/3/Diamond_Fret_Files.html

When I gave permission to use my response on this topic I had requested
the
above explanation be added. I do not have an answer as to why it was
cut.
Please accept my apology if anyone has ordered the above mentioned files
and
found then unsatisfactory as well.
