Steve,
I dont know about Ty, but I just build my wings in two halves , ala Pat Johnstons method. and then join them into one peice. Sheet the mid center section after its joined, it aint going no where.
that way you dont need a super long jig, or have any need to splice the arrow shafts.
Actually come to think of it, on my Avenger, the wing construction would not allow a two piece wing, so I had my jig table setup full length, then I built one half of the wing, slid the tubes through the ribs part way, built up the centersection, slid the tubes some more, and built the other part. Actually worked pretty slick
