PM sent to Mark, as well as email through his web site....
I was using an atty with a very short and nearly recessed 510 pin, which was really having a hard time making contact with the 510 of my WAE2.... Well I ended up messing up the 510 pin on my wizard! 

 By unscrewing it so far as to try and make connection with that recessed atty pin, when I tried to screw the WAE2 510 back down and it wouldnt budge... so then I unscrewed it a little to get it moving, well the center brass screw part came out of its brass bushing that fits inside the top cap, and ALL attempts to get it to go back in would not work.......... The threads on either the pin itself or the little brass threaded bushing have gotten all messed up now... As a make shift solution to continue using my WAE2 I ended up just kind of pushing the 510 screw (think press fit) back in to the brass bushing thing, to the point where it doesnt fall out, but doesnt screw in or out either....so now my WAE2 adjustable pin has been damaged........... I am sure its an easy fix, all I need is that whole little brass assembly which just pushes in to the top cap, its like a screw and nut kind of deal.....  now just waiting for Mark to get back to me.
On a side note, that 510 adjustment should be made to be adjustable from both ends..inside and outside.... that would be a great addition IMO.
