Mike, if my memory serves me right Chappells shop is 32' wide and uses a king post truss with the bottom cord (tie beam)in 2 peices, joined to the king with wedged half dovetail tenons. That might not be the example for your project, and that joint should be in his book as well. I would look it up but I lent the book out a year or so ago and haven't got it back yet. That joint isn't a splice. Tim
