Paul,

thanks for the suggestions. I have nothing against screws (or any steel for that matter) as long as they are used in a way that is asthetically consistent with the rest of the joinery. The joints as currently designed is housed 1" plus a 2" tenon which should proved sufficient bearing surface. I am wondering if you have used (or seen, heard...) of Timberlinx being used in jack to valley joint. One other idea is some simpson metal on top of the jack to valley joint (let in slightly so decking planes out properly). This would not help pull the joint tight put would help keep it there (and make the inspectors happy)if used in conjunction with screws. I assume by screws you mean lag screws? My jacks are 6x8 and valley 8x10 or there abouts,

Pete
