Speaker wiring
Quick question regarding speaker wiring. Railpro is capable of impedance loads anywhere from 4 Ohms to 16 Ohms, and will output 2 watts and 0.5 watts respectively at these impedances. I'm using 8 Ohm 1-watt max speakers. Up to this point I have been wiring them in sets of 4 as series-parallel, so I have been right at 8 Ohms, 1 watt.
3D printing help
Looking for contacts for this very special project. To explain the project:
My Dad has a old Lionel HO (yes HO) steam engine. Back when I was a teenager, the engine was not functional, and I took it apart and found out why - a plastic gear on the main drive axle was cracked, and instead of driving the main axle, would just spin in place. The gear was removed and we attempted to find a replacement with no success. The engine is still fine, but the gear has gone missing over the years.
Weller iron and soldering to frogs
As work progresses on my new layout (old was DC), I've now soldered my first feeder to the frog of a Micro Engineering switch, that little nub underneath.
HO buffer for steam loco tender in passenger service -- are they made?
Steam locos in passenger service have a buffer on the rear of the tender to control the car movement. Sometimes the buffer is included on a brass model but often not. I'm looking for one for an ATSF 3700-class 12,000 gallon tender but can't find any. There are tons of brass accessory parts for steam locos but I can't even find a hint of an HO buffer -- not even a mention of a long out-of-production one.

Any 3D Designers with Printer Out There for N-Scale
I am having a hard time getting anyone to respond to my queries about building something in 3D for me. I have tried several times to contact people who sell thru Shapeways without any luck. I never get a response. So I am looking for some help.
Because N-scale does not have a DCC ready Santa Fe style 4-8-4, I am in the process of merging the guts of a Con-Cor DCC ready 4-8-4 GS4 with the shell of a Bachmann 4-8-4 Northern.
An assessment of the Kato P42 engine
Normally a multiple sample set of tests is required before any statement can be made with certainty.
However, recently a Kato P42 Amtrak engine with the motors in the trucks was made available for
testing.
The results of this engine's initial tests were such that a summary of this single test was justified.
While looking at individual parameters the uniqueness may not stand out, when looking at the
performance overall the unit is in a class by itself.
