A couple questions/observations about the positive contact and button assembly:
On the two pictures from page 6 of the build doc, it appears that the small solder lug connecting to the button screw should be placed above the large one connecting to the 510 with the nut on screw joining them together on the top side...
In the first photo, the end of the screw joining the two appears to be flush with the surface of the nut (unless that is the hex head of the screw and there is a circular indentation in it?) In the second photo,though, the screw is protruding beyond the nut. My screw was protruding as in the latter photo, and when assembled as shown, it also extended beyond the top of the recess housing it in the internal frame and prevented the top cap from sitting flush. Once I had tightened the joint, I filed the screw end down flush with the nut to prevent that from happening. Turning the screw around so that the head faces up would also have done the trick, but it would have made it all but impossible to tighten that nut, if needed, without unscrewing everything to remove the lugs.
Also, can the smaller lug be placed below the larger one? I was liking the throw of the button slightly better when I tried it that way, but I haven't fully assembled, yet, and I didn't check carefully to see if there might be adverse mechanical consequences.
Finally, those lugs, once held flush to the top of the internal by the 510 nut, make for a stiffer leaf than I was anticipating. I'm not sure that even the heavy button spring is actually contributing any resistance/return to the button throw beyond what the lugs themselves already do. As I said in a previous post, I really liked the subtle, loose feel of the button when I first tried the opposing magnets, before the lugs were in place. I'm thinking I might try replacing the small lug with a piece of 18ga stranded wire in order to retain that feel. It would also allow the button to travel more-or-less straight down rather than at the angled arc prescribed by the attachment to the lugs. Of course, it would also make the mod no longer purely mechanical, but I'm wondering if anyone can see any other obvious adverse effects?
have you seen this, gdeal?
