Following the process described previously I came up with an 11 to 12 degree angle from the hoirzontal plane. This checks with virtually every other reference. Once we angle the cone up 1/2 of this value and establish a center line we'll start on the neck and go over some details. Updates will be few the next couple of days, but I will try to get back to this ASAP. If you want to learn more about taper etc xheck out the link below.
As always, Keep on Trekkin! =/\=
