Does anyone know off the top of their head what is the best bit size to drill a hole for the on/off switch.
For the round rocker switch that comes with the LI, I used a 3/4" hole-saw bit, and added a notch for the key with a small file. Worked perfectly on the piece of ABS plastic where I put the switch. The hole-saw had something like a 1/4" pilot, for which I pre-drilled a hole.

^ Nice. :)
The reason why I couldn't help answer, focal, is that I free-handed it. :o From my past hobbies, I'm pretty decent at using a Dremel, and I tend to free-hand these things. :eek:
I measured the switch first with a ruler and it looked like 3/4", so that's what I used, and the fit is perfect. The tricky part was getting the white plug for the LI wiring harness through that hole, it's a tight squeeze.
If you look closely at the back of the switch, you'll see that there is a plastic key or tab at 3 o'clock that fits into a notch to keep the switch from spinning around in the hole.
I use a "unibit" or "stepbit for these tasks. You can pick them up at home depot or sears. I own two sizes, .5 in and .75 in. I do believe the hole I drilled was slightly less than .75 in for a nice pressure fit. Unibits are nice because you can drill through wood, plastics, sheet metals, and other non-super dense material. Just incase your wondering what I'm talking about, it's bit that looks like a really tiny Christmas tree or cone. It drills perfect holes in steps.

I just looked them up they can be expensive.
Ok My math sucks, what size would be a hair smaller than 3/4 to play it safe, 5/8?
Also, could I use a spade bit, or that is more for wood?
The exact measure is 20mm in diameter. Sorry, metric only :)
That 20mm is for the inner diameter, not the outer bezel right?Quote:

Correct. It would be a diameter of the hole...Quote:
