Trucks (was Rusti Tank cars

 

开云体育

I suspect anyone who has been buying S scale for a while has some miscellaneous odds and ends; I have at least 7-8 orphan (=singleton) trucks and my own bag of assorted Northeastern truck parts.? Occasionally I acquire more and can actually assemble an extra truck or two, or match one of the orphan trucks for a complete pair.??
With the current 3-D printed roller bearings, as used for Ben Trousdale's covered hoppers, we also have AM, SHS, and PRS roller bearing trucks as well as the Downs/Ace from among which to choose.
From memory of reading/hearing about the Ace line, apparently it was developed by a prominent supporter of S scale who had even bigger plans for it (such as brake beams or shoes to fit the brackets in the sideframes).? Whatever happened (perhaps he died) the Ace line was in danger of disappearing when Russ Downs bought it.? I always liked their trucks, especially with metal wheelsets, and still buy them whenever I see them reasonably priced.

The mold was made to shoot 2 Bettendorf side frames and 2 Roller Bearing side frames. At that time almost no one was buying Roller Bearing trucks. Russ had TUBS of them. The tank cars were made to use the R B trucks. In the end it flipped because of the tank cars and Russ put some Bettendorf on tank cars because they were surplus.

And speaking of odd things that defy our logic!? Among the remaining things, the BBB has a bag of parts for the NE/Kinsman trucks.? As far as I can tell no complete trucks can be put together, so it's something like the Ace trucks--a balancing act!? I'll have to thumb through the remains soon but at least those parts will make good hopper bay weights!

Hey Jace
I don’t have any parts.
Wanted to let you know…because you helped me with diesel SIDEFRAMES and HIRAIL WHEELSETS….when I was in need!
I wish that I could help you!

Re: Today’s S Scale project

 

Here are some more pictures of this evenings progress.?
The cab is soldered together. The floor was fabricated to fit the cab and against the back of the boiler. It to is soldered to the cab bottom. There is now both crew seats made and soldered together and soldered to the floor. The cab is just sitting on the boiler which is sitting on cylinders and motor. I can also now see that I will have to lengthen the draw bar to get back the three feet spacing between the tender and cab.?

Next will be drilling, tapping the boiler to bolt it to the cylinders and then make a bracket to solder to the cab floor and drill and tap to the rear of the frame.?

Next will be cutting the fire box up to clear the top of the rear drivers and make ash pans.?

Once all that is done I will make the deck extension on the tender finishing it up. The tender will get painted after that.?

I will then make the removable back head covering the motor.?

To the best of my knowledge, genuine SwitchMaster motors have always been a 3 volt DC Hankscraft motor made in America.? With a resistor in series, they can operate on 12 volts or whatever DC voltage you happen to have.? Here is a quote from the SwitchMaster web site:
?
SwitchMaster motors actually operate on just 3 volt DC. A 1200 ohm resistor is included for 12 volt operation.?
?
There was a time many moons ago when a cheap knock-off product was offered using a motor from China.? Forgot the name of the company, but the motor was really cheap and did not last long.?
?
As an interesting side note, this specific Hankscraft motor was designed for "operating" (moving) display signs in retail stores.? Remember those signs with a dog's wagging tail which actually moved.? The design goal was to have these signs run on a couple of common batteries and have the sign operate for over one week without needing a change of batteries.? As is common, we model railroaders steal good ideas from elsewhere and use them for our own purposes.? It is true that our DCC products could not exist without all the small, miniaturized components contained in cell phones.

Re: Diode Lighting circuit

 

No.? His question was about the diode network.? He provided a photo making it even more obvious.? He made a mention of LEDs, but they aren't applicable to the network.? I pointed out in one of my comments that LEDs did NOT apply.

Your test light is not "wrong."? It just has a limitation.? If you have a high resistance connection as the cause of insufficient current to your locomotives, the LED light tester may not catch it.? This is not my opinion.? This is how electricity works.

Re: Diode Lighting circuit

 

Incidentally, if anyone want to read some info in depth about measuring DCC voltage, I have this document I wrote at my Droipbox site.? I wrote this mainly for the Digitrax groups but it has been passed around a lot.

It has everything from test lights (which is usually all you need) to meters that will work and why some won't, oscilloscopes, and so on.? There are many appendices for those who want a deeper dive (there is a lot there).? One appendix shows how a "sensitive ohmmeter" can be used to help find shorts.? At a large HO railroad I work on at a museum, this has been invaluable.

The one sort of test light that I do NOT show is an LED with a resistor.? It is advantageous to have more of a load on the DCC voltage than an LED provides.? Some who use an LED light tester also clip a lower resistance across the rails to cause more current to flow.? The reason for this is that there can be a questionable connection somewhere that might be read fine with the low current draw of the LED test light, but not with more current such as when you try to run an engine, and it still doesn't work.? All of the test lights in the document draw significant current to simulate a load.

But the diode circuit shown WILL destruct if put directly across the rail power unless not much current is available from the power source.? It is a question of how much power each diode has to dissipate as heat.

They have been different voltages. What voltage are yours?

If no one can direct me to a source for parts for these, another possibility might be looking for junkers that I could cannibalize for what I need.
Anyone have any?? Preferably cheap?

I figured it was a constant lighting circuit, perhaps directional, too, and that the bulbs mounted in the shell are probably low-voltage which would blow if they got any significant part of 12v.

Mike Swederska?
I am taking an uneducated guess here, but it looks to me like the circuit enables the lights to illuminate BEFORE the motor starts to rotate.? Thus, the lights could be on while the train is waiting at the station.? Or something like that.? Just a guesstimate, but what the heck..........it might be correct.? Ed L.
