Various Player Rebuilding Questions
By Larry Fisher
1. I believe I've received a few attached files from this group. They
end up in my \TMP directory with no extension after the file name so I
can't tell what kind of file it is. One of them that I looked at looks
like a zipped file. If anyone here recognizes the file names I have
listed below, I'll add the appropriate extension to the file name and
deal with it from there.
rediskla 4/23/96
soundcar 3/21/96
refilter 4/28/96
I think the refilter came from DUG@westnet.com but if anyone can help
me identify these files I'd appreciate it.

2. I'm presently working on a Hoffman piano with a player in it that
has never been rebuilt. One thing that I'm always curious about with
every player I work on, is how is cloth weight determined for the spool
box motor. I've seen some people recover them with pneumatic cloth,
and although that provides very little resistance and therefore very
little air to run it, the cloth I would expect would not hold up in the
creases and folds for very long. Using a heavier cloth would increase
the resistance and therefore increase the amount of air to run it. I
try to match the original cloth as close as I can by "mic-ing" (using a
micrometer) it. Replacement cloth is usually a little heavier. I
really liked the wine colored motor cloth that PPC had years ago, but
he doesn't carry that stuff anymore. Any suggestions??
3. I recently looked at a Thiery player that had been rebuilt some time
ago. I estimate that the work was done in the 60's because the
pneumatic cloth is still very pliable but its cracked at the edges
where ever there's a glue line. Also, this reasoning is weak I
realize, but the valves are untouched, and that was the way to go in
the 50's and 60's. I've seen this same type of failure on an Ampico in
a grand that the owner claimed was recovered in the 60's. Any input
from anyone out there on what causes the cloth to self-destruct at the
glue line??
Regarding the motor on this one, the cloth was cracked at the folds
on this one. The weight of the cloth felt about right but it looked
funny. It was black, but had a bit of a shine to it, like it had a
higher nylon content in it than the cotton cloth I've been using from
Schaff and PPC.
4. I'd like to hear what people have to say about the rebuildability
of a Krell or Artimus player. The one with the cat gut valve disk
hangers, and the self contained valve block pneumatics. The one with
the self-destructing metal plates/housings and deteriorating cork
gaskets........... fun stuff eh??
