Is it dangerous to nail a top plate into a wood main support beam

Hammer 🔨 | Posted in General Questions on

Hi hope all is well. So I’m building a wall underneath my main beam to create a partition wall in the basement. The house is very old so nervous that nailing a top plate underneath the main beam which is wood would put additional holes into the main carrier beam or potentially damage it. I was thinking of using construction adhesive to attach a 2×8 or 2×10 to the underside of the beam. Then once that dries building a 2×4 wall underneath and nailing my wall into the glued peice of wood. The 2×4 wall would keep the wood in place and I could nail into the glued peice. This would stop my from making additional holes in main beam, with a 3 inch nail going through a 2×4 and then another 2x8or10 it might penetrate the main beam a little but I can’t imagine more than a 1/4 inch.

    Unless the beam is rotted or otherwise damaged (and then you have bigger problems to worry about), I wouldn't think twice about fastening into old wood.
