Otherwise construction continued as described in the supplied instructions. The first step was to do some filing and trimming of the points. The points "hook" into the tie plate, and swing around that hook. The points had to be trimmed with a small file to get a proper fit. Also, flash had to be removed from the throw bar and tie block pieces. All of these parts where then laid aside for future use.
Next, the frog block was glued in place. Its proper location given by small tabs on the bottom, fitting into holes in the ties.
