Epoxy:
3M structural adhesive left underneath the cabinet (we have 6, we need 2)
The mix ratio is 2:1 and provides 20 minutes of work-life, allowing time to adjust for the desired fit prior to curing. This adhesive reaches handling strength in approximately two hours and is fully cured in 24 hours at 72 °F (22 °C).
To get rid of extra epoxy, heat up a soldering iron up to 150 degrees celcius, and use rubbing alcohol
Make sure the gun matches, push and pull the tabs
Thin line, 2 hour cure time
2 adhesive tubes will do the trick
make sure the gun you’re choosing says “3M structural adhesive” on it
...
Use quadro static mix nozzle (we have 5, we need 2)
It is recommended to use a new tip or mixer nozzle for each cartridge
MAKE SURE TO TILT UPWARDS AND TRY TO GLUE
very viscious
Gasket:
cut to-size
not a priority
Notes:
Do not epoxy any of the 3D prints; we will validate them after
Day 1:
Bring enclosure frame and panels to the machine shop
Grab 3M structural epoxy from underneath chemical cabinet (20 minute shell life)
Clamping width pieces: should be straight forward because there are holes in the fibre-glass due to vent + fan holders. Orient the box so there is room on the sides to clamp
Clamping length pieces: ~3.5cm from the top of the steel frame to the top of the fibre-glass. Grab the metal clamps from the drawer in the bay and clamp the top. To ensure the bottom is flush grab something heavy and place along the bottom and sides
Wait for epoxy to dry
Cut adhesive gasket by 1/2 to make it 1/4 inch thick, then epoxy to lid, clamp, and let dry for 24 hours (ask Michael if waiting for 24 hours is necessary) before proceeding
...
have a partial 3D printed baffle with length 15mm instead of 5mm to make sure holes align at the right spots for baffle
assemble all 4 side panels first so you can clamp from the bottom BEFORE gluing in the bottom piece and weighing it down with books/something heavy
flip the enclosure upside-down when gluing the side lid panels so gravity can due its work. Q: how to make sure this lines up correctly?
If it takes 24 hours to set the panels - you would have to wait between each step (length, width, etc.)
NEED TO FIND OUT WHERE TO ORIENT CLAMPS - stability
make sure enclosure feet fit to Chassis, test screwing-in bat box to enclosure
