Anybody modified a Zebralight before?

[chrispy513]

While it's not about a knife, I wasn't sure where else to put this question, so mods, I apologize if I'm in the wrong here.

I just recently received a Zebralight H52w in the mail and I've been reading about some of the tailcap magnet mods people do, but I haven't been able to find a decent how-to. Has anybody here tinkered with one of these lights?

Specifically, I'd like to get a neodymium magnet inside the tailcap but don't know what size/strength I would need or exactly how to go about getting it where it needs to be to work properly.

Thanks in advance for the help!
