Interim Progress, 6/05/16Side details:

The feature that most distinguishes the St Charles cars from the 1902 coal cars are the four extra stake pockets on the car sides. Grandt S scale "single U-bolt" stake pockets match Derrell Poole's drawings exactly. Tichey 0.035" and 0.030" rivets were used for the bolster bolt heads on the side sills and and for the brake cylinder mounting bolts.
Ends and end details:
As built, the St Charles coal cars had a pair of stakes on the outside of each end. Per Derrell's notes, sometime before 1907 (likely when automatic couplers were installed c1903), the stakes were removed and new stakes installed on the inside of the ends, leaving two visible vertical rows of bolt heads to mark the position of the inside stakes.
Coal car 4160 c1902 with the original outside stakes. Note truss rod bolt heads and washers, original retainer position. Also note the wood brake beams.
Coal car 4188 in Blackhawk, 1913. Note the vertical rows of bolt heads for the relocated stakes, and repositioned retainer pipe. The purpose of the extra stake pockets is explained.
To model the stake bolt heads, I used Tichey 0.025" rivets, positioned per Derrell's plans. The new inside end stakes are Grandt "high-side" gon stakes cut to fit. The individual corner irons will be applied last, after the car is painted C&S red and the corner irons are blackened or painted "grimey black".
The St Charles cars had an unusual vertical, rectangular truss rod washers, and the truss rods were secured to the end beams with large square bolt heads, not threaded nuts--the turn buckles must have been the only way to tighten the truss rods. I used Evergreen HO 1x6 strip (0.044 x 0.066) for the washers and squares cut from 0.020 x 0.040 strip for all 4 truss rod bolt heads, including the inner two on the buffer block face plate.

Tichey 0.030" rivets were used for the smaller bolt heads on the end beam. The retainer is from the PVC kit. Retainer pipe is Plastistruct 0.010" rod; it may need to be replaced with 0.008" wire..
This week: Grab irons, coupler lift levers, brakeman's end platforms (both ends in 1909!), then to the paint shop to paint and weather the interior.
