     Dittos to your post.  Is North American parts a brand or a =
style(meaning stwy factory parts.

    Speaking of that I've used both the factory supplied Renner wippens =
and also the new maple factory made wippen and I think they fit the old =
actions better than any thing else I've tried.  The maple wippens come =
in at about 18 or so grams(wow) and are an (almost) exact replication of =
the original part.  The Renner parts slightly more 20 iish grams but =
they fit as  well. =20
     There are more specifics if any body cares but I'm off to church =
just now .

   Talk later

Hi Dale,
            I've found the Tokiwa parts to be every bit as good as =
Renner and Abel.  The wippens are 1gm lighter than Renner, and are =
maple.  A definite advantage where touch weight is a concern.

Like you I have a complete set of Renner, Abel, Tokiwa, and North =
American Parts.  It takes all the guess work out of ordering, when you =
do mock up prior to starting.

I like to do DW/UW/friction measurements with the old parts, then =
install each part,  measure and compare to see cause and effect.  I then =
order the parts.=20
This I do, after rebushing, fully servicing, and fitting the keybed for =
correct bushing clearance etc.
As this can skew results, and it further reduces the risk of error.

Maybe this will be helpful to some.
Regards Roger

PS.  Some of Wally's parts are Tokiwa.

      I've done this twice and I believe that the parts I used to match =
the old ones came from pacific(the tokiwa parts).  As much as I've heard =
these parts denigrated by some I have found the complaints unfounded. In =
fact they are  very well made parts and  I don't hesitate to use them =
when needed.  I suspect that Renner and Brooks(Abel) have parts that =
would fit as well and I'm sure that the new line of Tokiwa knabe and =
chickering wippens will be a welcome asset to our parts replacement =
endeavors and possibly yours. To my knowledge no other maker provides =
these style wippens
        Typically when I replace action parts I have a complete =
set(almost) of sample parts from most parts makers that I simply match =
the best part for a   particular application.  Myyyyy, isn't life Grand =
to have so many choices these days.  Persevere Wim a solution is out =
there.=20
     Finding appropriate parts isn't difficult like it used to be in yrs =
past.  I'll you have to do is order them.  Each part maker I know either =
has demo kits or a full size picture of their parts.
       One last word of caution.  The chickering piano used very light =
hammers and matching them is difficult. Beside a 6ft. 4" chickering  =
would benefit tonally from more hammer weight(strike wt.) which means a =
shank with a different knuckle spread might be a better choice to help =
carry the extra gram or so.

    Best

    NO!! :-) Definitely not if it is going to be in a recording studio. =
I would=20
    think that a change of flanges would be the safest route in this =

    I=20
    don't think that one of these thingees, with brass flanges, would =
have been=20
    suitable for a recording studio even when they were brand new.=20



  OK, so if bar-b-queing the flanges is not recommended, then I need to =
go on=20
  to the next step, which is replacing the brass flanges with wooden =
ones. I am=20
  more than happy to do this. But, and this is where I was hoping some =
of you=20
  could help, what size do I get? Has anyone had any experience =
replacing brass=20
  with wood flanges, both the hammer and wippens.=20
