If you are stopping a crack in sheet metal, it is standard to drill a hole to relieve the stress, they do that on airplanes.Ok thanks, old joist is toenailed in, I'll get a new bracket for the new one. I gyess it is just a piece of dead weight now. I will prob just leave it in for a little extra real estate for the subfloor. Also, I notxhed the ends by a 1/4 inch in order to roll them up there. Ive seen where its a good idea to drill a hole at the corner of the notch where the horizontal and vertical edges meet, in order to help prevent splitting. Do you know if this is necessary on a 1/4 inch notch?
The engineers her would prefer us just cut it down to match and if we are leaving the old in place we put a small angle to that cut so it will roll up easier. If the floor is nailed to the old one non of the small details at the top matter. But you will be fine.Ok well good to hear, I figure if it splits its going to be that last quarter inch so not a big deal. And I can fix that. Also old joist is bearing just fine at the ends so going to leave it. It did shrink in its 40+ years of life, thats why I had to notch. Was measuring a hair under 9 inches, and new joist was 9 1/4.
