I was not suggesting that he exceed the code values. While the current code
requires a 3x plate for shear above 320-plf (approximately since I don't
have a code in front of me) plates have historically been nailed to 1-1/2"
plates. I've seen few sole plates fail in cross-grain failures unless very
heavily nailed (say 2-inch on center). In this case, his plate is probably a
full 2-inches since it is an old historic structure.
He should be able to nail at least 8d common nails at 3-inch on center
without splitting the studs or plate.

Subject: Re: RE: Improving Shear Capacity of Existing Plywood Sheathed
How is the heavy concentration of existing and new nails handled at the top
and bottom plates? Seems like there would be a pretty significant
possibility of splitting.
