Sometimes shopping locally is a bust and sometimes a boon. Sometimes little shops will charge you through the nose and sometimes they will give you exactly what you need for a song. They are always more interesting than a big box.
Enough background.
----------
More scouting was done to find suitable parts from the list. A hobby shop was visited to find a continuous rotation servo or a gear motor. The continue rotation servo in stock was underpowered for the application. The gear boxes were expense for what they were. Small gears were purchased to attempt to create a gear system for lowering the platen and pushing a glue stick. The gears will likely be held by using wire brads in a wooden structure. A bear box will not have feedback like a servo so some kind of speed monitoring will be used. Most likely a small magnet on a gear matched to a reed switch. The speed monitoring could record the number of motor rotations each time the planted is moved or each time the glue is pushed. If a suitable gear box cannot be built servos will replace the gears on the parts list. Salvaged motors from RC vehicles will be experimented with . The motors already have gears on their shafts.
A local bike shop helped select matching sprockets and a piece of chain long enough to catch all the sprockets. The shop was Bicycle Chain.
Another thrift store was visited and a second option for a water container was purchased. It was a square container but the three shaft design will be kept.
The hobby store was Hub Hobby in Little Canada.
