I'm trying to get better about taking photos about what I'm doing. I think it adds a little color to the posts and it definitely makes it easier to remember what I did when writing the journal.
Enough background.

A package of replacement bike chain links was purchased
in order to shorten the scrap chain. An
attempt was made to drill out a link since a chain tool was not available. It proved unsuccessful. A bike shop will be visited and requested to
perform the service or a chain tool will be purchased.
Chain links from a hardware store
The hot glue gun element and nozzle mounting issue was
addressed. The heating element cavity
had a hole and measures slightly larger in diameter than 5/32” since a #8 bolts
fits easily. A spare 2 ½” bolt purchased
for the servo mounting provided a mounting screw for the nozzle. The diameter of the nozzle is larger than 3/8”
in diameter but was drilled with a 3/8” bit.
When the nozzle hole is expanded the nozzle should fit against the ¾”
aluminum bar snuggly. Heat dissipation through
the aluminum may be an issue.
Components for nozzle mounting
The nozzle with a too long bolt
Nozzle and bolt separated
Nozzle and bolt through mounting plate
Profile of nozzle and bolt
To do:
Mount aluminum bar to plastic with countersunk bolts from
the underside
Clean saw blade and glue to servo
Build circuit and wire
Install in mint tin enclosure
Test + debug
Revise documentation
