Internal supports for an Antique American Girl Toy Sewing Machine

thingiverse

The American Girl toy sewing machines were produced by Delta Specialty beginning in the early 1920s. The internal structure is a tin casting which has a tendency to break. This 3d model is designed to replace the original casting. Two designs are provided. 1. A complete framework 2. A split framework that can be used if the gear wheel on the hand crank cannot be removed. In both cases, a part of the casting is designed to be separated to allow it to be off-set in the sewing machine. This 'screw post' must be threaded on both ends with an M5 x 0.8 thread. Taps to cut the threads are inexpensive and available via Amazon and other sources. A separate 'screw post' file is also provided, in order to allow the user to print several in case of difficulty in creating the threads. I used a spare 3/8th inch drill bit to serve as the thread spool, which worked well. See YouTube video entitled "American Girl Toy Sewing Machine: Part 2" for further information.
