come out of the wall at a 45 degree and the 5/8 ceiling and the 1/2 wall board will hide it. Sealing around that is another problem.
vent stack installation problem
Hi all.
I goofed on installing the vent stack. In short, I put two vent pipes in a partition wall that I built last year and joined them, intending to vent one side up into the attic and through the roof. Only after everything was connected and just perfect did I remember that I attached the top of that partition wall to a ceiling joist. The vent pipe is 2-inch. The joist is attached to the wall just along the edge such that the pipe would need to dig 1/2 inch or so into the joist. I don't suppose I can cut into a joist without compromising the truss system, right? Or add a cleat and go for it? or cut in at the bottom of the joist just enough to fit an elbow?
The only other workaround (hate to workaround) I can think of is to run a soffit along that wall and elbow the pipe out of the partition wall and into the soffit.
Any other ideas?
Thanks.

I'm sure codes would have something to say, but if that bottom chord is supported along a length of that top plate it should be fine with a little creative modification.
There may be a nailer on top of that top plate as well.
Will this be inspected?

That was a surprisingly accurate drawing you did of the situation. I actually had more 2x face to work with since my joist was actually flush with the wall, so I was able to get this with a 22.5. Of course my holes weren't lined up, so I had to get two 45s shift it over inside the wall, but all's well that ends well.
