The stem pieces are the same at each end and are gotten out of a single board. There are no splices or scarfs. As with many small parts that have duplicates, I temporarily glue two boards together and cut once. The challenge with the stems was getting them positioned correctly on the bottom. They are so small that it is hard to find a method that works well. The 1:1 version can probably be done by setting the stem in a vise and positioning the bottom over it. That didn’t work for the model because it’s too hard to see the joint that way, and the tolerance for a good fit is incredibly small.
It took three tries to arrive at the method shown. The bottom is aligned on a cutting pad, where we have lines drawn to ensure angular accuracy. That’s weighted down. The stems are then clamped to a machinist square and glued in place. 1:1 fastening is bedded with glue and fastened with two screws for each stem.
