Yep. I’d been notching the retaining rings for a while. As pictured here, in the prior thread about this:
That approach has the annoyance of having to “de-twist” the driver wires, then fit the driver into the retaining ring, then twist to tighten. The retaining ring in that picture isn’t fully screwed in.
Someone somewhere suggested it was reasonably safe electrically to just let the retaining ring press down on the top of the 7135s, so I tried that for a while — and when I dropped the flashlights, this was the result.
I know, “then don’t drop the flashlights” is the conclusion.
I’m wondering how much of the innards of the 7135s is at risk if I start rounding off the corners, as those would be easier to file than the retaining rings.
