Repair a brass steam loco.

    I have an Overland brass loco in which the box it came in lists as a Frisco 4400 4-8-2. It has spoked drivers not scullin disk as the spec sheet illustrates. I purchased this at a train show more than 25 yrs. ago and now that I have a layout in progress I would like to run it. The layout is DCC, so instead I have some leftover pieces of flex track and hooked up a dc transformer to see if it runs, it did but irratically. I discovered that the crank that the lubricated arm (I think) attached to it fell off the main driving wheel that holds all the side rods together.
    The tiny (I mean TINY) little screw that held this crank is stripped and or the screw hole is stripped also. Is there anyone out there that can help with this. It would greatly be appreciated!

    Since it is not lightly that you would find a replacement driver, your only course of action is to drill out the rods, and driver, and then tap it with the next size screw. They may be metric; you will have to determine if they are metric by removing another one and mearsureing it. NWSL sells metric screws and MicroMark sells Metric taps.

    I'm not sure what fell off. If it's the eccentric crank, when I finish an engine, I don't rely on the screws, I just solder that on.

    Don,
    It is the eccentric crank. If you solder it on, how do you place the angle or degree of the crank in relation to the side rods? I am not a steam familiar type modeler

    Which side is it on? I'll post a picture.

    This might make Don shutter, but I'm soldering challenged! I've done the same thing just with a dab ACC glue, you must be very careful not to get glue where you don't want it.

    This should give you an idea of the position of the eccentric crank. Position it, and if you're comfortable with it, put a very small dab of flux on the end of the crankpin and use just enough solder to fill the gap between the pin and the crank. If you're not, then a small dab of gap filling ACC. Don't use the watery stuff or it will end up gluing everything together.
    When the rods are down, counterweights up, the eccentric crank should lead about this amount. Can't do it like the real ones sometimes, but this will work.

    That's a nice photo - wonder what happened to the tender?
    Looks as if it was attacked by a roadside bomb!

    It is the engine that was sitting in the siding on a freight train when the 1520 came along with a passenger train and went head on into it. It's the only one of the 4200s that doesn't have Baker valve gear. They put Walschaerts on it when they rebuilt it.

    Don--What was the location and date of the 1520 vs. 4208 wreck?

    Thanks, Tom

    Tom -

    The 1520/4208 accident was on February 16, 1939, at Quincy, Mississippi.

    1520 was on Train 107. She hit 4208 at about 45-50 MPH at 4:20am. Quite bad - 3 fatalities, 38 injuries.

    Don,

    Do you have a date for this pic?

    I would have to guess sometime after Feb. '39. Both engines returned to service fairly quickly. The trees are leafed out in the photo, taken in Springfield. This is a company shot, maybe Louis Greisemer could pin it down. Taken by the test lab.
