»THE  MILLIONAIRE«

2nd Phase of the Project: RESTORE THE 2nd MILLIONAIRE TOO ...

Project Phase 1:   MAKE   ONE-OUT-OF-TWO ...

SN = 838           ( ~ 1890 )           SN = 2607

The right one has all Arithmetic Setting Knobs ...



... and its Case is in better shape: This one!
After hours of cleaning ...



Many screws were broken from former "repairs"
( Due to electrolytic reactions: Iron screws in brass bodies )
Windings had to be drilled - Some parts were not accessible

1st Problem: System locked, because LOOSE IN THE MAIN SETTING ...



... Filing the OVAL HOLES back in conic shape to fix it tight ...



... 2rd Problem: CYLINDER WRONG SYNCHRONIZED - AND! ...
... 3nd Problem: A MISSING PIN on the 10s-Carry/Reset lever ...



( Exchange not possible, because of locked screws in both units )
... Removed the residuals of the broken pin - Made a REPLACEMENT ...



... and fixed it with component glue ...



( THIS is the "Home-Status" of the cylinder )

4th Problem: Errors in 10s-Carry arithmetic. Found the reason:
The Carriage was loose, because of worn-out TRANSPORT HELIX ...



( Results = OK, when carriage pressed to the right )
... EXCHANGED the whole MODULE including its SHIFT BAR ...



... Results in new ERRORS BECAUSE OF WRONG TIMING due to "Hardware-Constrains"
D I S C O V E R Y :   PARTS  MAY  NOT  BE  INTERCHANGEBLE  !!!
( This is true also for symmetric parts from left to right or vis-versa !!! )
===>>   Manufactured  BEFORE  "Industrial Revolution"   <<===

Old modul with worn-out helix  B A C K  into the calculator ...
Solution: (1st) Shorten the left side of the Shift Bar 5/10th mm
(2nd) Washer on the right side of the Shift Bar
to PUSH THE CARRIAGE TO THE RIGHT SIDE ...
... and it worked !

After lots of "cosmetics" ( eg. fix the broken rivets of the lid ... )
This is the FINAL STATE before finished assembling the whole machine:



A BEAUTIFUL PIECE OF ENGINEERING - BROUGHT BACK TO LIFE !

And here is THE MILLIONAIR's Power ...



... The Instant-Multiplication ( & 10s-Carry )   Module   ( = " 1x1-KOERPER " )
( R E M A R K :  TESTING with a 4 mm PIECE under = x1-Factor )

How the "1x1-KOERPER" works ...
