Just got back from installin this baby down in Baton Rouge.
This particular machine was a Katrina victim that arrived at our shop in Texas
with 9 gallons of water in the gear box and had been standing in 18-24" of
water after the roof was blown off the shop it was in
I totally disassembled it, cleaned it all up, reworked a few sub assemblies,
installed a new motor and electrical control box (<- both had been underwater
which is bad mojo for electrics !), replaced all the lil shit that goes missing
over time on one of these machines, performed the usual rebuild operations
required on a vintage 1969 Heidelberg press and it's ready to go another 50 yrs
or so

Good job MrKim, now come down to Australia and fix this piece of American crap,
G25 Baker Perkins my company purchased 3 years ago. This press cracks so may
plates even at .4 gauge that its driving my PrePress dept nuts. The amount of
spares we need to run for a 5 million run is a joke. Give me a good old
Heidelberg any day, the other 4 Heidelberg Web presses are a dream.

Crackin out plates truly sounds more like an operator error than a machine
problem Frank. Has the operator gotta hard on for someone in pre-press or what
? In my profession we often find operator error to be as common (if not more so)
as actual machine issues.
The most common problems in this area are operators taking set-up short cuts,
deciding they know better than the manufacturor and implementing their own
procedural processes as opposed to the ones outlined by the manufacturor and my
real fave ...... lack of simple mechanical maintenance procedures and
lubrication of a machines assemblies and sub-assemblies.
So long as a plate is mounted and packed up correctly it's difficult to see how
the machine itself would have much to do with it cracking plates out unless the
plate adjusting mechanism is exerting undue force on the plates clamping areas
and causing it to crack from these forces when performing registration moves to
the plate cylinder.
It could even be that a change in plate mounting/packing procedures with this
machine might be in order. A sign of pure lunacy is to continue doin the same
thing over and over and expecting a differing result from those same actions

Hey MrKim
No its the press mate, we have some of the best printers in Australia working
for us, even a chap from the US who used to work on the G25. When we moved to
ths .4's ( plates ) we dont need packings any more, the .3's + packing was a
real problem.
As far as maintenance goes this machine gets the Royal treatment, it is a poorly
designed piece of work.The amount of oil it goes through and leaks you could run
a small nation on. Australian insurance laws does not allow the fitting of a
sump therefore theres always oil / ink build up under the units.
The bend on the plates isnt the best, about 8mm on grip edge / back edge, the
grip edge is more prone to cracking, some units more than others. BTW its a 2
unit, 4 colour duplex press, can run 32page Quarto @ 50,000 per hour easy.
Plate size 605 x 985 mm.
Thanks for the feed back mate.
Regards Aussie_Frank
