could you tap first, then press it in with the atty attached for clocking?
and I'm guessing the atty doesn't come off the mod too often...or ever
Interesting River...you could turn the threading off an FD body and finish it +.001 of your deck hole bit and counter sink the deck to accept its flange, you could then screw the FD on the RDA, orient and indicate, then press the FD in...that's not a bad idea
I mean, obviously this is only going to apply to mods like a Grand or a Dibi "style", where the top deck doubles as a conductor and you need seamless electrical continuity.
Like all you guys, because I build my own mods I've never understood why one would be swapping them all the time?, if you got a great RDA, build a mod for to sit on, it's not like an RDA is going to work better from one mod to the next, 3.7V is 3.7V...although that's probably why I have 15 functional mods

...though I bet I still have less than Cappy
I do have several "conventional" mods where I test new RDA's before I decide to hybrid them, i.e., I follow Catfish and decided to pick up the "hype" of the week and got a Mini Freakshow clone off ebay. I'm liking the "under air" design like the Magma and Lancia (which are 2 great RDA's imo), but there's just something wrong with the Freakshow, the air is more "under/side" than "under/center" by virtue of it's design...anyway, I won't be bothering to hybrid the Freakshow. But when I find an RDA that's a true solid performer, then ya, hybrid it and stick it on either a new mod I build for it or, in the case of the Derringer, it bumped the hybrid'd Magma that was on it...I have to keep my major PITA fingerprint magnet brass Grand current
As it's working out, I now have 2 classes of mods, the conventionals and the hybrids and the hybrids are becoming my elite status mods from a performance perspective...like a number of you guys are realizing, we go through all this work building the perfect mod...only to have it brought down by junk 510's made by others (same reason why I started making my own mech switches). The hybrids aren't hard to swap, you just have to undo the bottom nut, then you just spin the RDA off as usual which I do for periodic cleaning)...but if that extra step affords me a rock solid, no leak, no v drop marriage between the mod and the RDA, screw convention
...just sayin'
