1.    Construction

 

General: A Prototype photo was used from Model Railroad Freight Cars (Kalmbach Books, 1971) (Tab 1)

Prototype dimensions: tank: 38 x 7.7 feet; deck: 43 x 9 feet

Planning: During construction the article Build a Pennsy Flat Car was used to guide initial construction (Tab 2). Build an AC Flat Car was used for underbody (Tab 3).

Overview: This model used 194 individual parts, 16 decals

Tank: I made the tank of scribed 1/8 wood, steamed for 30 minutes and bent around a one-inch styrene pipe.

End Trim: Prototype dimensions call for a scale 3 foot circular trim for the ends of the car. To get a prototypical width, I steamed for 30 minutes four scale pieces of 2 x 6 stripwood and bent them around a 1-inch styrene pipe, secured by rubber bands and left overnight. I cemented the two stripwood circles to the end of the staves of the tank. filling the gap with canopy glue, sanding it smooth.

Railings: I made railings out of brass wire. Scale Fasteners were made of Detail Associates eyebolts. Railings were painted, then buffed, then inserted through the eyebolts. Railings were temporarily kept away from the tank to permit brush paining of eyebolts and touch-up. Then a drop of canopy glue was placed on each eyebolt shank and the eyebolts pushed into the tank for correct prototypical clearance.

†††† Dome with handle: the dome was made from a Shepard brand light duty pad from Home Depot. The handle was brass wire formed around a block of wood and cemented to the pad.

††† Grabirons: I fashioned a jig out of bass wood and bent3 scale foot grabirons around it.

††† Bands: I cut strips of card stock 3 scale inches wide and brush painted them with grimy black. The bands were positioned on the tank and cemented with canopy glue to the tank support timbers. As on the prototype, extra supports were placed on the lower ends of the straps.

†† Underbody: I followed plans for standard flat car (Tab 1). Circular pads for bolsters were made from thin styrene and a paper punch.

4. Finish and Lettering

       Although the prototype photo shows an unpainted car, the article says that the usual prototype color was Tuscan. I verified this with online research, and so painted the car.

       Floquil aerosol Tuscan on tank.

       Prototypical lettering on tank and sills of underbody.

       decals finished with Testorís Dullcote

       Floquil rust and roof brown (70/30) used for the couplers and wheels

       Hunterline stain used for planking

       Micron archival ink pen (black and rust) weathered planking

       Black colored pencil used for weathering planking

       Polly Scale grey used for underbody overspray weathering

       Sharpie markers were used for touchup

5. Scratchbuilt

General:Canopy Glue was used throughout. (It dries sets faster than White Glue, is less adhesive and therefore easier to remove, if necessary).

       194 individual pieces, 16 decals

       styrene used for underbody

       brass rod, styrene rod, piano wire used for underbody piping

       scribed wood for planking , tank

       strip wood used for end rings, walkways

       wood channel used for end supports

       Brass wire used for railings

       Eyebolts used for rail fasteners

       12 grabirons
