Iscribe interview questiosn3/5/2023 ![]() ![]() I've often substituted a center framing member (a ceiling joist), rather than cutting that third stringer. Personally, I don't like cutting three stringers, when I know two will suffice. I've built a few hundred sets of stringer out of 2x10 and cannot remember any strength issues. That is precisely why I questioned the need for stronger stringers and more "meat". The second story stairs always have a supporting wall under them. We install the wall studs in such a way that they carry the stringer. In residential houses, the basement stairs are always framed in and drywalled. ![]() I'm searching my memory banks for instance where stringer strength is an issue.about the only situation that I can come up with is exterior application where there is no under stringer wall or support. go read someone else's post.Īctually Jerrald, adding the center stringer is mandatory on most 2nd story stair systems because they will receive drywall on the underside and drywall won't span 36", the minimum width of most stairwells. If accumulated errors do occur, we start looking for the root cause.īlueIf you want to read a fancy personal signature. Personally, I use the accumulated error as a tool to teach accurate layout techniques. By keeping that dimension accurate on the final would render all the accumulated errors moot. If it suddenly became a concern because of questionable layout techniques, I'd force the issue on using my "speed patter" plywood technique and/or insist on a direct measurement between the top nosing edge and the top edge of the landing. The notch accuracy question has never been an issue. Incidently, we do employ notches in approximately 75% of our stringers. It will create an accurate layout that would rival your diagonal method.unless a rookie is doing the job. If accuracy is an issue, create and use a "speed pattern" which I make out of a corner of plywood in about 30 seconds. Here's my instructions to the kids.err apprentices: If strength is an issue, double the stringers carrying capacity by laminating (sistering) a 2圆 underneath.which normally fits perfectly. Additionally, it increases the chance that the headroom might be uncomfortably tight, yet meet the minimum code (you might be surprised at how oftn a tight headroom situation comes up.even in big homes.). This falls into that category of."it looks wrong" because of the gap. ![]() I guess everyone has their favorite ways of doing things, but I wouldn't recomend this to any rough framer. It took a few years before I burned all of my router patterns.I still warmly remember that equisitly freeing day! I think I stopped doing that somewhere around 1990. Allen, I used to be somewhat enamored with the idea of laying out a stringer mathematically. ![]()
