Dual Switch Panel Mod, Part 2
Well, as life tends to go, tomorrow turns into next week. But today I did find time to nearly knock out the rest of the switch panel project!
Where I left off last time I was ready to get the switch panels mounted together. The plan is to bolt the two together as is usually done in most guides, but also apply some epoxy and additional fiberglass/epoxy reinforcement.
I'm using 8-32 x 1/2" panhead cap screws and nylon locknuts,
JB Weld Plastic Bonder epoxy, and some generic fiberglass tape, similar to
this.
I started by drilling a couple holes in the right side panel for the bolts.
I then test fit the panels in the TJ again so I could clamp them together and mark the exact spot I needed to drill in the left panel.
After I drilled the holes in the other panel I bolted them together and did another test fit in the TJ to confirm everything lined up. Still looked good, so we move on
I then scuffed up all the areas around where the two panels meet up, this will be to help the epoxy adhere to the plastic.
Both panels were cleaned with alcohol. After that was dry I quickly mixed and slathered both mating surfaces with a thin layer of epoxy and bolted them together.
This next step is where I've deviated from other guides I've read.
At this point the fit and feel of the panels was nice, and would certainly work fine! However, there was still small a bit of flex between the two panels. My plan was to use fiberglass tape and epoxy to further bond the two panels together; this is a method I used to use for fixing cracked rooftop cargo boxes when I worked at a rack shop.
Previously when I cut up the right-side panel a triangular piece of support was left in place. I wrapped it with fiberglass tape all around.
I then mixed up more epoxy and layered it on generously, covering as much of the tape as possible. The end result isn't pretty, but it is quite effective!
After letting it cure for about an hour the panels were noticeably stiffer where they're joined. Success!
The last part for the panels is to create a new right-side mount. Previously when I cut off the original mount on the right-side panel I was careful to cut it off neatly so I could reuse it for this step.
While the epoxy from the previous step was curing I cleaned up and drilled some holes in the right-side mount. I later discovered one of my holes was too far down to be useful, and I needed to drill another. Oops
I again went out to the TJ to test fit the now combined panels, this time bringing the right-side mount with so I could align it and mark where I need to drill into the switch panel.
I drilled the holes in the panel, scuffed up both mating surfaces and cleaned them, and proceeded to epoxy and bolt the right-side mount to the switch panel.
Last step will be drilling some holes and installing some nuts into the dash for the right-side mount and this project will, for the most part, be finished!
