<DIV> <STRONG><EM> Hi Mark</EM></STRONG></DIV>
<DIV><STRONG><EM> I have installed many Renner parts but not as of
yet the Tokiwa kit however I plan to make it my next install choice. I have
looked closely at the parts & have samples. It's good to have more than one
choice. Right?</EM></STRONG></DIV>
<DIV><STRONG><EM> In the past....far past ,Tokiwa parts, as you
alluded to, had seizing pin/parts problems. I spoke with Randy Morton at
length this past summer about my pinning concerns. The short story is that
the problem was a procedural one at Tokiwa which took a while for the Management
at Tokiwa to acknowledge. IN the process of Randy proving the problem to
them they built new test equipment which quickly caused the parts to seize up
after about 2 to 3 thousand repetitions. ummm!
well... </EM></STRONG></DIV>
<DIV><STRONG><EM> After this encounter Randy hired the
engineer that literally wrote the book on Yamaha flange pinning technique and
brought him to Tokiwa book and all, where he employed the tried & true
Yamaha materials & techniques & for many years
now.</EM></STRONG></DIV>
<DIV><STRONG><EM> This was good for me to know. The fastest way to
loose money is to use parts that have problems that can only be solved by our
free/expensive labor to ....do over! </EM></STRONG></DIV>
<DIV><STRONG><EM> Also next time you need more sos tab clearance why not
use a cardboard shim on the rear of the old blocks.</EM></STRONG></DIV>
<DIV><STRONG><EM> By the way the New Tokiwa wippens for Steinway are a
spitting image of the Renner part provided by the Steinway N.Y
factory. I have a set on the shelf. They are beautiful
& I am installing this set soon in a Stwy D. I have compared them side
by side with the Renner parts & you cannot tell the difference except the
Tokiwa parts have a number conveinently located on the repitition
lever.</EM></STRONG></DIV>
<DIV><STRONG><EM> FWIW</EM></STRONG></DIV>
<DIV><STRONG><EM> Cheers</EM></STRONG></DIV>

style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">Does anyone out there have recent
comparative experience with BOTH the Renner and <SPAN
class=SpellE>Tokiwa</SPAN> damper back-action kits? I've installed several of
the Renner kits, but the quality of the pinning of this last one left a lot to
be desired. As you can see in the photo the post pinning was substantially out
of square. The flange pinning of this particular underlever was also off, but
in the opposite direction, which had the effect of throwing the post even
farther out of alignment. This was probably the worst example in the set, but
many others were off by lesser amounts. I'm thinking that I might try the
<SPAN class=SpellE>Tokiwa</SPAN> kit next time, but I’ve had problems with
seizing centers on other <SPAN class=SpellE>Tokiwa</SPAN> parts in the past,
and as a result I am reluctant to use them in
general.<o:p></o:p></SPAN></FONT></P>

beech to <SPAN class=SpellE>Delignit</SPAN> <SPAN
style="mso-spacerun: yes"> </SPAN>for the tray material, so be careful if
you’re drilling for the flange screws using their countersinking bit – I
snapped one of the screws off due to the higher density! Next time I’ll ream
the holes out a few thousandths more. The other lesson that I learned on this
one is to check the horizontal clearance between the backside of the post and
the <SPAN class=SpellE>upstop</SPAN> rail. Since the new style sprung
sostenuto tab flanges extend slightly behind the post they were rubbing on
this particular example, which I corrected by making new pivot blocks with the
hole located about 1/32” farther from the belly
rail.<o:p></o:p></SPAN></FONT></P>
