FS: Welte T-100 and Ampico "B" Parts
By Jim Miller

Over too many decades I've acquired parts of various sorts.  It
occurs to me now that others might have better use for them than
myself.  Some are of T-100 Welte-Mignon origination whereas others
are Ampico "B."  Here they are:

1. An Ampico "B" later-style take-up spool made en facsimile some
decades ago by deceased and lamented dealer, conservator and
entrepreneur Frank Adams, formerly of Seattle in Washington state.
It is the one where the left end is intended to insert into a ball
bearing.  (I think.  I am in no way Ampico educated.)  This solid
beauty, of which Frank made only a few, features five square posts
for attaching a roll's tab, rather than the usual hooks, as in the
earlier design.  It is of raw wood just as supplied, and so will
require finishing for the first time.  It is extremely well built
and would serve as a fine substitute for any missing, rare original.

2. An Ampico "B" tension-level "feeler" that was to bear against a
playing record-roll, so as to sense it's beginning, middling and
ending diameters, which in-turn would serve to regulate it's attending
pneumatic's hold-back tension while playing.  It has still about half
of it's gold (or lacquered brass) finish and, is in perfect condition
for operation.  (It is a "metering-pin" sort of affair, and is
fascinating to contemplate as a mechanical/pneumatic device.)

3. A very nice Ampico "B" take-up roll frame.  It seems mostly complete
on the right side including it's clamp-type spur gear though it has no
shaft (easily machined to perfect match -- they'd never know), though
a shoulder screw is missing that secures the steel tracking shift lever
which is present.  The left side is missing that lever as well as the
"out" sense finger and pallet/duct assembly.  These can be made with
not too much trouble so as to be matching to-perfection.  Both are
mounted, still on their original wood sides.  I believe it to be of
the earlier or first style, than that of the latter.

4. A "B" tracker bar complete with 'vibrating' tracker ear assembly.
(This had to have been a product of the brilliant physicist mind that
was Dr. Hickman's.) The "0B" and "0T" openings are without their
nipples, apparently having fallen off at some time.  Can easily be
replaced.  (I can re-surface these to perfection.  Most that try it
flatten at the square ducts' edges, thus randomly deleteriously
affecting roll/duct signaling.  The resulting effect is not one ideal.)

5. A Poughkeepsie style cast aluminum T-100 take-up spool complete with
shaft and beautiful brass driving spur-gear.  (This features the
continuously adjustable left side, which is nice.)

6. A Welte-Mignon wind motor complete with fly-wheel.  This creature
features legs (Tripods!), and is very long and slim, and rotates in the
correct direction for driving T-100 record-rolls.  (When facing the
flywheel, it's produced rotation is clock-wise.)  It stands-up on it's
feet like something of alien appearance, as Wells himself might have
envisioned for his "War of the Worlds".  I assume it was intended for
use in a Vorsetzer, to be mounted on one's right inside.  It will
require recovering but, the originals are still in place on two of the
three pneumatics.

(Note: stiffeners really should be re-created for three-point wind
motors.  Without, their force/stroke for a constant input is somewhat
inconstant.  Not ideal.  Statically and with the fly-wheel off and with
a spring gauge and thin cord wrapping a reference 2" diameter cylinder
as attached, the output force and it's constancy over the whole of
rotation may be determined.  It should be confirmed that it is constant
all around.  After, fly-wheel on, remount, and you're good-to-go.
There are numerous subtleties regarding vacuum motors and their driving
regulators.  IF properly coordinated, a regulator will increase it's
force output in response to an increased load, much as a fly-ball
governor does, and thus maintain more of a constancy of speed than not.)

7. A very heavy and very imposing flat resistor of the delightful
Frankenstein Laboratory sort sporting two knobs on it's top and four
screw binding posts at it's end.  Originally, this was from a Vorsetzer,
I believe.  The switching was done by pneumatic-displaced mercury bulb,
one of which plus it's container is included but, not the pneumatic.
(Easy!)  On a plate at one end it says: "No 6162; PS 1/6; Volt 120;
Per 50."

(In your open, unenclosed mercury switches place just a covering bit
glycerin on top of the fascinating but poisonous metal.  This will
prevent splashing and oxidation and, can be washed-out if become dusty,
thus preserving the mercury and, adding precious years to one's Mignon
restoring, preserving and listening career.  Any glycerin remaining on
the extracted plunger, will then fully drip-back into the porcelain
container.)

8. A too-complicated valve block for the later two-tiered stack Mignon
jobs.  (More valves and stuff than Carter ever had Little Liver Pills,
almost.  Long ago I understood every duct, valve, backcheck and
interaction, but since have given-up such efforts at comprehending.
As simply put: new generations will have to take this up.)  These were
originally positioned at the left/top of Vorsetzer and piano installs.
It is of natural wood not painted, and is in quite nice condition, the
hand lettering on the front appearing much like new, practically.
A very nice item for inclusion in one's Mignon Cabinet of Curiosities
in the Welte Parlor -- the above wind motor, too.

9. A black-finished wind motor excised from a Bechstein Welte.  It was
removed by myself by Imperial Command of Joe Tushinsky himself, to be
replaced by a Bodine drive(!!) I kept it for just this very instance
-- it's disposal or better, in hopes that it might be replaced back as
original.  (Sorry! I had no choice! J.S.T. was very persuasive.)  It's
flywheel got separated somehow, or, it is the very one on the other
alien appearing one just above, can't remember which.  (Dang! I do have
this but I cannot get my hands onto it.  It is hiding, and lurking
somewhere in some box.  Not lost but, presently just elusive.)

For any that might be interested, just ask for photos and they will be
taken and digitally dispatched post-haste.  I am here to serve.  For
one item or for all, any not-unreasonable offers will be accepted.  My
Email is above but, be sure to remove "geentroep" before sending or
I might never hear from you.  I can be spoken-to as well.  Just ask for
my land-line phone number when you inquire.

Thank you!
