How Not To Build Stairs...Stair Building Part 3
Or maybe I should say, 'The stairs that PL Premium built.'
This is the last stringer I was cutting. I was almost done with it. Just finishing the cuts with a jigsaw and this happened... A previously unknown check-split caused this section to just fall out!
So I went a little glue crazy as you can see from this picture. I glued the original f-up and wow it does appear to be stronger...but then, but then, I noticed a ton more cracks in the stringer? WTF!?!?!? I swear they where not there before. So I went through the stringer and glued those also...Then I dropped the other stringer and caused a crack in one end so I glued that too.
I also glued on little triangular tabs so that the joist hangers would bear fully on the wood.
The pros that saw this original set up with just the two Simpson brackets holding up the dropped rim joist where very suspicious that it would be strong enough. So, I took several of the triangular off cuts and used them as braces.
Another major issue the pros' found with my set up was how the left hand side of the stringer was unsupported. That all the force from the stairs are carried in that corner and leaving it unsupported the stringers were guaranteed to crack. If I was smart I would of jiggered the rise/run so that the heal would of landed on the concrete wall...now I'll have to add additional support here.
Enter the concrete anchors...It was suggested that I use 1/2 lag bolts to support a ledger that would take the stair load. I had an extra piece of PT 4by4 lying around so I decided to use that. To use the lags you need to drill a hole in the concrete 3/4" in this case deep enough to set the lag shields in. Then, when you insert the lag bolts the shield expands and locks everything in place.
Turns out, using a 4by4 probably not the smartest way to go... Keeping the holes your drilling on the right path is pretty tough with that much wood to chew thru. As one pro suggested, 'I shoulda used 2 2by6's'...I had to adjust one of the holes in the wood but the other two where spot on. Man, I hope 3 bolts is enough...I tightened it up with my impact driver and WOW does this seem sturdy. Hopefully it will be sturdy enough... I completely aggravated the two bulged discs in my back doing this...If I have to drill another couple of holes I'm going to cry like a little girl...
Here's a shot looking down the concrete wall. I'll have to shave off a bit of the new ledger probably but I'll do that as I need to when I set the stringers. Next up is to take it easy for a day at least...it's just ice and Advil for me for a while.
Then I want to cut the treads, coat all the cut ends, I'll set the outside stringer. I'll probably install the posts and the railings-guards on the outside stringer...and install the middle stringer, but I'll have to wait to install the final stringer and to screw the treads down until after I finish residing the back of the house...
Ouch my back hurts...
