  the massive disassembly operation.
• Left hand side of Cooper engine.
• Looking at sideshaft with eccentrics that operate

• Clyde Burkholder watches Charlie Bromer
  cut through mounting bolts
• #2 cylinder and tail crosshead slid back prior to removing #1 cylinder
• The crew counted nine members in this group photo plus
  in right front is Karl Herman, who once ran these engines
  and gave us some pointers.
• Hoisting the #2 cylinder assembly
• Lunch is served...
• The Cooper's underground muffler was very stubborn
  when attempts were made to hoist it from the ground
• Finally, it broke free
• The #1 cylinder assembly has already been removed
• The building was literally torn down around the project
• The crankcase rises from its home of almost 60 years.
  A 100 ton crane was provided by James and Son Excavating,
  the general demolition contractor.
• The #1 cylinder assembly swings to the trailer
• The 23,000 lbs #2 cylinder assembly is gently lowered to the truck
• The 30,000 lbs crankcase is lowered to its trailer for transport to R&T
• As the buildling is dismantled around them, the remaining engines
  await the scrap heap. Number "0"s empty pad is
  visible in the foreground.
• The hard working crew enjoys a rare restaurant meal

• One of Roger Gerhart's tractor trailers swings into the
  Rough and Tumble Grounds with a load of Cooper components
• Roger Gerhart's two trucks wait to be unloaded
  at the Cooper's new home
• Amos Zimmerman's 20 ton truck crane was on hand to
  hoist the heaviest components from the trucks.
• Hoisting the front cylinder assembly
• The Cooper's crankcase is airlifted for the last time
• The rear cylinder assembly rests on R&T soil for the first time
• The crankcase is ready to be rolled into the Gas Engine Building
• A forklift and some logs are all it takes to roll the
  crankcase into the gas engine Building
• Clyde Burkholder moves the 9.5 foot long, 11,000 lb
  crankshaft assembly to the gas engine building
• Roger Kriebel greases the bearing and gear surfaces
  of the massive components of the Cooper engine

• Components of the Cooper wait for the foundation to be poured
• Half of the Cooper's flywheel
• The Cooper's pistons wait for reassembly
• On October 13, 2001, the base foundation for the new home
  for the Cooper Engine was poured

• February 14, 2003 - The complex forms, reinforcement rods
  and long mounting bolts must be carefully laid out and
  constructed on the base form before pouring concrete
• Charlie Bromer welds rebar while Pete Weisbrod
  helps and Clyde Burkholder gets more rod
• Charlie Bromer had an incredible maze of rebar
  to weld together
• Brian Mann secures mounting bolts in pvc "sleeves"
• While Charlie, Pete and Clyde work below, Brian and
  Bill secure the Cooper attaching bolts above.
  NOTE/ the form to provide space for the flywheel is suspended
  via cables in the foreground
• Paul Stoltzfoos cuts rebar to length
• Brian Mann (above) and Pete Weisbrod had many
  support bolts to install in the form
• Clyde Burkholder and welder Charlie Bromer discuss
  the next rebar weld while Brian and Pete work on
  engine support bolts.
• Bill Hazzard and Brian Mann (above) confer with
  Clyde and Pete (below)
• One of the exhaust pipes is anchored to the form.
  Exhaust will be carried to the outside muffler.
• Brian Mann works with Pete Weisbrod on shimming the
  suspended flywheel form while Charlie Bromer
  welds in the left corner.
• The maze of rebar and support rods, soon to be
  buried in concrete, nears completion
• Bill Hazzard makes a final inspection of the rebar and supports.
• The first two trucks of concrete arrive. Pouring was done
  simultaneously at both ends of the form.
• Bill Hazzard begins the first pour into the empty form
  while Brian Mann and Paul Stoltzfoos look on
• At the other end, Pete Weisbrod monitors the pouring
  from the second truck
• Bill Hazzard directs the concrete while Paul Stoltzfoos
  spreads the mix in the form
• A massive amount of concrete was required
  to complete the foundation
• Bob Campbell and Paul Stoltzfoos look on as
  Bill Hazzard directs the flow of concrete
• Pete Weisbrod was kept busy with the vibrator to help
  settle the concrete and eliminate air pockets
• Roger Kriebel directs the pour while Charlie Bromer
  and Clyde Burkholder look on
• Brian Mann with shovel and Pete Weisbrod pour
  around the flywheel form
• It was a long stretch of the mixer's boom to reach
  the middle of the large form
• Paul Stoltzfoos guides the pour for the edge of the foundation
• (l to r) Bob Campbell, Bill Hazzard, Paul Stoltzfoos and
  Pete Weisbrod fill the right edge form
• When the flywheel form was lifted slightly by concrete poured
  beneath it, Charlie Bromer had to reweld some broken
  joints in the rebar while standing on a "floating" piece of plywood
• Charlie repeats his repairs on a different weld, hoping his
  plywood support does not sink before he finishes the weld
• Bill Hazzard and Brian Mann smooth the concrete
  now filling the edge form
• The form is finally filled around the exhaust pipe
• The crew worked feverishly to level and smooth large
  areas as the pour nears completion
• The last truck tops up the middle of the form
• Almost done the pour, the crew assembles to watch
  the final area to be leveled and smoothed

• At the 2003 Spring Steamup on April 5, Roger Kriebel shows
  the crankcase end of the completed foundation.
• If you had not seen the form being built, you could never
  appreciate the complexity that lies in all this concrete.
• Viewed from the crankcase end of the foundation, Roger's image
  indicates the massive size of the foundation

• In May 2003, the Cooper's 30,000 lb crankcase was raised on blocks
  prior to being slid into place on rails
• Now on rails, the crankcase is pulled to the foundation
• The crankcase is slowly moved to a point above its mounting bolts
• At Spring Steamup, 2003, the mounts for the two cylinders
  and the crankcase are in position.
• The crankcase sits above its mounting bolts with the lower
  half of the 14 ft flywheel positioned nearby
• The crankcase and flywheel half await further assembly
• To be continued...
