Timber Framers Guild Forums Tools Timberframe Design Simple questions from a beginner

1) Solid top plates are not an option. Will a spline joint be sufficient above the two middle posts? Or should I give the covenant scarf joint a go? Being your first project, dive right in and make a scarf.

2) 3" girt tenon length suitable? Probably not
3) 2" brace tenon length? 3" is standard

4) 3/4 or 1" pegs? 3/4" for 1 1/2" joinery

5) How critical is straight grain green hardwood for the pegs? Dry hardwood would be better, and stronger.

Can I get away with green pine? I wouldn't.

6) 2x rafters with birds mouths toe nailed to plates? (Cheating I know, but this is a good starter project)
Ok, I guess.
