This is a 12x20 roof design I've been working on to use the pine timbers I was sizing last week. Everyone wants tails on trusses and they are doing it by raising and poorly connecting the tie. This might be one way around it, I'm trying for something basic that can be a "kit". Strengthwise it is easily passing at 7.25x7.25 in #2 white pine with a 40 psf load. It has thrust restraint, top chords are sufficient in bending, the only load on the bottom chord in bending is self weight, no worries there so a king is not neccessary, just a simple rigid triangle. I'm shooting for affordable so trying to be heavy timber but bare bones.

You could do part of the mortise and tenon cut on the mill to save having to do it all by hand. You could do it pretty much all but the shoulder cut really with a side table set up.
