I have my roof rafters up, made from 3x6, I am putting a roofligt in, which needs additional framing, 150mm thick.
The plan is to attach another 3x6 to the existing 3x6, making a 3x12. I can see ways to attach the ends, with the cross members, but what is the most sensible way to attach the pieces in the middle ?
Options so far are 1) bolts right through - don't like this cause you will see the ends 2) screws - put in at angles need the touching edges
Any better options, 10 inch nails would do me, but I don't know anywhere that sells such a thing.
Thanks Rick
