    I took a few photos of the MDC shay I'm working on.
    What started as a simple tune-up turned into a major rebuild.
    This photo shows the MDC/Athearn driveshaft To complete the repower.

    I regauged this one to standard gauge by replacing the axles and installing these spacers on the sideframes.

    That's where I am with this project. I need to fabricate wipers for electrical pickup and wire it, then finish detailing and painting.
    More later.

    The rear sand box is the original MDC box with a few modifications.
    The center was cut out, then styrene fillers installed.

    Notches were filed at the bottoms of the boxes.
    Then a sheet of styrene was installed to represent the back of the water tank.
    This photo shows the back temperarily in place before the notches were filed.

    This shows the fillers added to the dack of the cab. It's hard to see in this photo but there is a fabricated boiler and firebox back temperarily installed. I just found a photo of the cab interior of a shay to go by to add a little extra detail to the interior.

    Shay gears

    Hello Ray,

    In the shot you sent up earlier, (attached) what type of gear housing are they? They look like they are metal.

    These are the wiper assemblies I made from .002" brass strap.

    Coupler lift bars and railings were made from .015' steel wire from garbage bag twisty ties. I stripped off the plastic coating and heated the wire over the gas stove, then quenched them in water to harden them.
    Sand hatches and a ladder were added.
    The water hatch was thinned and lowered.

    The flange for the stack was thinned and a new numberboard was made.

    Drew,
    I think a wire wiper would work fine. Be sure the wipers are flexable enough to apply light preasure to the wheels. You could cut the tabs off the original wipers and solder the wire wiper to it, using it as a mount. Then use some light wire to hardwire the trucks to the motor or decoder. (I looped the wire down around the bottom post of the sideframe to give more flexability.)
    Hardwiring will isolate the frame and make installing a decoder easier. If you are using the original openframe motor, it is easily isolated by removing the ground wire to the frame and wired to the decoder. Keeping the frame neutral will eliminate the worry of coupling to another loco or car and having a short.
