Steam engine quality [Virus checked] ['securiQ.Watchdog': checked]
- No question that in terms of appearance and detail the PSC K36 and 37 are
the best. I have one 36 (2002 run) and two 37s (1997 run). I also have
one Westside, one Overland, one Sunset and one PSC 1984 run 36 - that last
one is the rerun of the Westside model. The Overland is the same
manufacturer (MSM) as the 2002 PSC model.
The PSC 36 is the best runner, once the usual twiddles are done. In both
Westsides I've ditched the coreless motor in favour of a Mashima, and they
run much better because of it. The other all have Mashima as standard -
certainly the PSC 2002 and Overland do. I think also that the
PSC/Overland/Sunset are better prototypically; when you sit the PSC and a
Westside together, the Westside looks bigger, taller in the boiler and a
squatter stack. I think Peter T is also right about the boiler taper. If
you have the chcoice, go for a new PSC, second choice Overland. The Sunset
one runs OK, but in terms of detail is not good, and has real bad
steamroller wheels on the tender and loco trucks, but at least the rear
loco truck wheels are the correct size.
K37s - As well as the two PSC I also have a Fuji, redetailed as 494. The
PSC ones are properly detailed as per the prototype - my 490 and 499 are
quite different, and Mark Kasprowicz's 492 even has a completely different
tender shell with different rivet pattern. The Fuji pulls more, but that's
because it's a bit heavier. It didn't really represent any of the 37s
well, but was closest to 494. All have Mashima motors. And the PSC 37 runs
real well out of the box. Worth dismantling the tender trucks and getting
the glue out of the springs, and reassembling with new springs.

no wonder, those old high speed Nakamiki corless motor were the fist
attempt of the Japanese to copy the Faulhaber patent (as they have
done before with Rollei Cameras, Uher stereo equipment a.s.o.)
(The whole Japanse copy tradition statre din 1595 with an Portuses
rifle which they copied app 15.000 times in 4 years, nice tradition)
The Nakamikis were very poor in quality (screaming at top speed, no
torque) and in Japan itself cheaper than a 5 pole Mashima. I removed
all the Mashimas, Nakamikis from my engines and replaced them with
7500 - 9000 rpm Faulhaber or Maxons with flywheel. My PSC/OMI K 36
run much better than a stock PBL K 36 or even On3 scale engine.
Even the old WSM K 27,28,36 amd 37 will perform better than a new one
The mostly large flywheel (diameter must be larger that motor
diameter or at least the lenght must be a 1/3 of the motor) improve
performance a lot.
I removed the Nakamiki corless motor from my high grade WSM C 16
which was a jerky runner and built in a 15 volt Faulhaber 1319 +
flywheel to reduce the top speed. The result is unbelievable, either
crawling at 0.3 scale mph or speeding down the track at 35 scale mph
those engine runs superb, silent and smooth. I offer this as kit too,
but building in requires a lathe and some experience, so it is more
sophistcated as the rest of my now 120 re-motroing drop in kits.
