Hi,
I am planning on attaching some plywood gussets to some 2x4 rafters.
The rafters are circa 1960, and so are actually 51mm, and the ply gussets are 18mm each side, for a total thickness of 87mm.
I'm planning on screwing through all three pieces with 6 x 80mm screws.
Is there much chance of splitting the original joist? Would nails be better?
EDIT: If I can use screws, do I need to pre-drill? These are the screws I am planning on using.
