Thank's again to Eddie and Ryedan... I finally got around to taking some pics of the Igo-L on top of my XL. If you saw the pics of Ryedan's, mine was drilled exactly like his.
Just a little background first. As far as drilling it, I used a Dremel w/ #55 & 60 drill bits. I don't have a drill press so I improvised. I made a nylon spacer to fit over the +post, (1/8" ID x 3/16" od x same length as the post), and held it on with a washer and the screw that holds the wire on. Proceeded to drill the cross hole, (#61 bit), in the post. The spacer helped keep the bit from walking and kept it straight centered. It took 2 bits to drill it as the first was dull by the time I went through the first side. Drilling down through the post, (#55 bit), took all of about 30 seconds to drill. It was a little off centered through the bottom, but feeds excellent. I am not convinced the posts in the atty are SS because it went through very quickly. I wish someone would've told me the post comes out of the atty though. Much easier to drill with it out of the atty. Goes right back it nice and easy. Anyway, been enjoying the Igo-L on my XL for over 24hrs now and very pleased. It took a little more time than usual to change the battery in it this morning, but its all good....
Here are some pics of it... Please excuse all the nicks, scrapes, and gouges in the cover, as it is my all day every day vape. It has been dropped from ladders and the roof of the house a month ago, as well as being thrown down and maybe kicked across the floor once or twice!!! On accident, of course...
