Yeah, the problem with angling the atty is that the whole thing gets bigger. My intent here was to see how small I could make a BB
mod. I
could still get a little smaller because the two tubes spread away from each other a little when I was furiously sculpting, so the battery and atty are further away from each other than I originally intended.
The pocket firing is not going to be an issue. It has a little travel distance before it makes contact and the spring has quite a bit of resistance to it. I would guess (total guess) that it takes about a pound of pressure on it to push it all the way down. With most designs this might be a problem, but because of its shape and the fact that you push the button with the thumb it's more of a 'squeezing' than a 'push'.
I have been using it a lot today and it has not bothered me at all that my thumbnail touches my bottom lip while I'm hitting it. But I think I'll just bring the atty up about another 1/4 inch on the next round and that should be a little better. Also, I didn't really leave enough of the atty barrel exposed to screw and unscrew it easily either, so a 1/4" ought to make that part better too.
I think I'm going to try to make the next one in two pieces too. That way I can take off the bottom to get at the connector threads for cleaning and such.
