Dolls Cot Pre Assembly Rail Spacing 3

The construction of the rails were a bit of a challenge, however I rebated a 10 mm section into the frame, and then made some 30 mm long sections as spacers.
I then laid everything out on the bench to determine where the centers would be and to check the symmetrics.
I found the short sides needed a post at the center, where as the long sides needed a 30 mm spacer at the center.

With the application of glue I then assembled everything. then with a mallet and square adjusted everything for squareness and alignment with each other. Once everything was OK I let the glue set then sanded off the excess spacers flush with the frame.
