I want to install a new wood stove. But where I want the pipe to go through the second story floor requires me to cut a floor joist. I want to know if I can do that and if so how? My floor joists span from the outside wall to a beam 12 foot. My joists are at 16 inch centers. If I label the first effected joist as #0 the next as #16 and lastly as #32, I want to cut out 12 inches from #16. The section to be cut will be at 2 foot to the 3 foot mark on the joist from the wall. This leaves 9 foot hanging of #16 to the support beam. Can I just header #16 to #0 across to #32? This is the space I will be putting the ceiling support box for the double wall stove pipe to the stove.
Yes that is the correct way to do it. Just make a header. (a sandwich of 2 by X and plywood glued and screwed) Add a hanger if you can. (x = floor joist height.)
Can't you jog the pipe next to the joist without cutting it?
If not, you'll have to create the same type of opening as when a staircase is put in.
Do a goggle on "staircase framing" and you'll see what I mean.

thanks for your response. I looked at the staircase framing (google) but all that I could find was when they are supported by an upright to the downstair floor. I could not find any on an open floor plan downstairs without a supporting the staircase where the joists were headered. Do you know of a special web site describing a staircase without support to the bottom floor. Thanks again for any help you can provide me. I just need to know that it would work to do a header across from the first joist to the third, without resulting in sagging at the second joist.
