I am almost done drawing up my Guillemot, but I have one problem. I cannot seem to fit a 2x4 strongback that goes from the second form to the second to last form. I know you have to taper the strongback at the ends so that it will fit. However, in order for the strong back to fit within the forms, it has to be less than 1" tall at one end, this seems way to small. Has anyone else had this problem? Can I get by with going to the third to last form at one end? Any help would be greatly appreciated.
