So how do I get to the other side of the joint (for the second tack)

Dear Mike,

I believe the most common method is to cut a 6" dia circle in the jig-
board. Of course, that could leave the intersecting piece supported
by air. So you modify the hole -- use something other than a true
circle, such as a D-shape. Or you might cut away the wood and replace
it with metal (on the back-side of the board), to which you've tack-
welded scraps that will hold the intersecting piece in position. Of
course, if you are building just one copy ALL of the traditional
methods can be tossed out the window... so long as what's wheeled out
the door is an accurate copy of the original fuselage.
