1′-0″ in from the left and the bottom up 3′-0″. This leaves just 3″ (scale) on the right edge of the opening. (An option when you have a piece this narrow is to make the whole piece 3″ narrower, cut the opening to its correct width, then add a scale 3″-wide strip along the full height of the right edge. This is stronger, neater and avoids having a skinny and possibly deformed piece along the length of the opening. Use cyanoacrylate cement with care and sand the joint with 300- and 600-grit finishing paper to make it invisible.) As the photo (see last month) shows, the vent has a divider with its top 2′-0″ down in the opening. A strip of scale 3″

The Rr-87 and Rr-90 mechanical reefers shared the same refrigeration units, so the detailing steps on these cars are the same. Creative Model Associates No. 1016 plas- tic see-through roof running board materi- al was used for the grilles themselves. As explained in the text, styrene strips and CMA “iron railings” were glued to the sur- face of the running board stock for the frames and dividers. These photos show the A-end left side vents (above andleft) nearly completed and the A-end right side vents in progress and on the car. The cor- ner of a prototype Rr-90 is at the right top.
wide by .005″ styrene was used for this. Since solvent cements destroy such thin plastic, I secured it with cyano- acrylate cement. Again, Walthers Goo was used to hold Clover House screen in place. In the accompanying photos this vent on the Santa Fe Rr-91 is shown alongside the original Athearn PFE R70-20 car for comparison.
Rr-90 and Rr-87 vents The refrigeration unit vents on the
Rr-90 and Rr-87 classes are the same. The left side vent (looking towards the A-end) is a single grille with dividers. It has hinges along its left vertical edge and a small access door in the middle of the left half. See the photos. I used Creative Model Associates No. 1016 plastic roof walk material for the
50
basic grille material in these vents. This injection-molded, see-through running board is only .025″ thick, and, being plastic, works well for scratchbuilding in conjunction with strip styrene. I cut two pieces of the roof walk 7′-0″
long, just a bit oversized, and sanded the ends to match the hole previously cut in the car side. I narrowed each
piece to a scale 18″ wide and glued them together side by side. The outer rectangular framework was made up with Evergreen 1″×4″ strips glued to the grille surface. For the main dividers, I glued three pieces of 1″×4″ horizontally onto the grille, spacing them equally top to bot- tom to create four equal areas. The last
