    Place a spirit level on various treads to ensure they are perfectly horizontal. The presenter notes that some treads might be slightly high or low. Also, check the bottom of the stringer where it meets the floor. Mathematical calculations confirmed a 6.6mm discrepancy, indicating a small amount needs to be trimmed from the bottom stringer for a perfect fit. Use a spirit level to check the plumb of the newel posts, ensuring they are vertical.

0:05 Nothing like using a set of stairs not even fixed in. Hello everyone. Welcome to this video. Right, what we've got here is a great big hole in the floor. And what we've got behind me down here is a set of stairs. So what we're going to do today quite simply is put this set of stairs in this great big hole. So let's get some tools out. Let's crack on. Yeah, it was a good start, but uh when they unloaded it, they put it face down on the concrete with no bearers under it on the outward facing string. So hopefully that's not damaged. But we'll get this uh stairs up onto these stalls and have a look at this is a new supply we've not used before. I've never used before. Um they're looking good so far. They've cut the top, you see here, they've already cut cut the top string for me to go over the uh joist at the top. And also, um,

0:54 apparently, yeah, look, they've also, uh, pre-cut the Dow for me as well. So, uh, yeah, got high hopes for this set of stairs. You go. Oh my gosh. [Music] here. Lovely. Thank you. Right. First job is identify the top nule, which I've done fairly simple. There's only a few nules here. Uh test fit it onto this uh tongue on these uh outside string here. Uh again, what this company appears to have done, which other companies don't do, is actually uh pre-drilled for the draw dial. So, I'm going to put this new

1:41 on. And then what we got to do is basically cut the back of it out to notch it over the top of the joist. So let's give a little test fit, take some measurements from these joists, and then we can mark and cut the back of this uh new out. [Music] Yeah. Yeah, that fits lovely. Really nice. Obviously been uh test fitted in the factory. So, yeah, really happy with that. So, uh yeah, take some measurements of the joist now. Right. So, the measurement I've got from the top of the flooring to the underside of

2:26 the joist is 330 mm. So, this is the top of the flooring here. Uh this trench here. All I'm going to do is measure down 330. Basically, that is what we want to be housing out. We want to be housing out this part so that hooks over the joist. But I'm not going to come right to the top here cuz obviously 22 mil of this is flooring. So all the way around there. Yep. 22 mil. So really quite simple. All we're going to do measure down here 22 mm. [Music] there.

3:16 So, what we're going to take out is from this point, this just represents the joist to that point. So, to find out the depth of this housing here, all we've really got to do is put the the riser on the back of this tread and this housing here, mark on the back line of that, and that will be the the line that we cut back to. And then the back of the riser goes tight to the front of the trimmer or the joist. Right. So, I've got the riser here. And again, uh this being a new company, I've actually cut the risers to the length for me, which is really nice. So, what we do, put that riser in there. Make sure it's tight back to that housing. That's it. That's what we're taking out. It's quite a big uh quite a

4:02 big chunk actually. And also another thing they've done here is they've cut the top nos in for me as well. So that will eventually obviously just slot slot straight in there. So yeah, pretty easy. You can see that's at 22 mil. So yeah, get the saw out, make a series of passes here, chop that out, and then we can glue all this lot up. Right, I've just been looking at this and I've actually uh changed my mind. Uh again this is a new stair company the one that I use usually use uh the housing is normally set so it's halfway in the new and this is uh what we got here 36 37 mil.

4:49 So I'm not comfortable with cutting that much out of this. So I'm going to cut make this uh trenching here exactly half 45 mil and then I'll just pack it. I know I've got enough room in the stairwell. I'm just going to pack it off the joists because that's a little bit much too much to take out of there. It's going to weaken the new too much. So, yeah, slight adjustment on that. Right, that's all marked out. Let's uh let's get it cut.

7:16 in. Hopefully they should bush straight in. Look at that. Nice. Cut them off. Clean this up. We got to fit the uh top tread and the riser. [Music]

8:18 I don't know if I recorded any of me screwing that on. I thought I had and I went to the camera and it turned itself off. There's a huge amount of noise. There's a jet fighting around up there. So, I don't know if you can hear any of it, but uh the the riser and the top tread all screwed in. Now, we got to take some measurements off here. Transfer them to the chipboard flooring up there up the top there. cut that section out so that obviously this sits down on the floor joist but the top of the tread is flush with the flooring. Then we got to double check our floor to floor measurement and see how much we need to cut off the bottom of the string and then we can have a go at lifting it in. So I just realized that's a bit of a rookie mistake. The width of this nosing needed reducing because it's almost as wide as the joist. So if we cut it out the flooring wouldn't be on the joist.

9:04 All I've really done, I know I should have done it, thought about it earlier, I've just ripped down bit of ply, placed it against the uh riser there, and literally added on the the distance from the edge of the saw base to the blade. And if you can see, just ran that uh ran that all the way down there, and that's taken off the green. So, yeah, just tiny mistake on my part. Maybe not full speed in the morning, but yeah. So, now we can take these measurements and cut that flooring out at the top. Right. So, we can see I've cut the top of this uh flooring back. So, that's already cleaned off. We don't worry about this here cuz we'll trim that back when we put the uh floor nosings on. So, we're sort of ready. Now, what I'd normally do, uh again, the normal stairs I have, these strings are left over

9:52 length at the bottom, and you basically take a series of measurements. You can just see up here, take a series of measurements and sort of cut cut for the floor. But what this company have done uh is 196 mil uh rise. So they've actually pre-machined that in and it's actually 196 mil obviously from the top of the tread uh to the bottom here. So technically there's nothing for me to cut off. So what we've got to hope is is that the measurement that we gave them before the before we took a measurement from the finished floor at the top there down to the oversight added on the screed and that gave us the finished floor to finish floor measurement and that's what they'd made this stairs exactly to. So what we've got to hope is that the floor layers did put the floor

10:39 in the right thickness cuz we pretty much got no adjustment. If the floor if the floor is actually lower, uh if they put less on the screen than we asked for, then there'll be a gap under here. Um obviously if they put more on, we can trim a little bit off here. So we're going to offer these stairs in and see how it looks. Let's get rid of this. you good. I think you've got to go a bit more, Andy.

11:34 Yeah. Come on. No, no, no, no. Come back. Yeah. Come back. Right. Put your wind down a bit. Yeah. All the way. Go on the floor. Yeah. All the way. Yeah. Yeah. Right. So, we got it in just a tiny little adjustment at the top and that's gone in perfectly now. So, all I want to do check these treads for level and then see if we need to put this here. uh see uh if we need to trim any off the bottom of here. Obviously, as I said, I'll put my level on there to make sure that they're level. Check this uh once that's level across that tread as well. Check this for right. We can also double

12:20 check the measurements cuz we know what the uh rise is so we can times it by how many however many treads are. But yeah, even if hopefully uh either that's got to be jacked up a little bit, it may be spot on, but worst case we can jack up a little bit or we can cut a bit off it. So, let's double check that. Right. So, put my level on it there. Let's have a look. So, we can see there. Interesting. Look, that shows it's very slightly low. If I try the next one, shows it's very slightly high. The next one slightly high. So I think slightly high. Look. So I think uh we're very slightly high. So I'll check the mathematical measurements here. But it looks like we we're on the right side here. We might just have to trim 5 mil

13:06 off the bottom of that. So brilliant. Right. So just done a bit of mathematics. As I said, the rise is 196.8 and we got 12 treads down to this tread here. So uh that times by that is 2361. So, we should be looking for a measurement of 2361 from this tread up to the floor up here. So, let's have a look. As I said, I think we're a bit high. So, I'll pull my tape out. Here we go. What we got? Hold the camera as well. There. Yeah. So, as we thought, look what we got there. Can you see that? 2 3 55. So basically what we talking uh five or six mil we got to

13:52 come down. So yeah spot [Music] on. Right. That's that bottom cut there. What I've done now is cut a little prop if you can hear me. Cut a little prop under this side here. Um put a level across. It's showing very slightly high there, but I'm not worried cuz there's slight diff a little bit of a discrepancy in this bottom step. More importantly, what I've done is make sure that the shoulder of this tenon on the string is plum, which it is perfectly. So, pretty happy with that. Um, now we need to do simply is find the bottom nule. We can take a measurement from the top of this tread here down to the floor. Cut that newle. get that new on

14:39 and not forget at the same time as putting that new on to uh make sure we put the handrail in. So yeah, looking really good there. The stairs has gone in uh nice now. So as I said, get this bottom new on um get the handrail in simply a case of fixing it to the wall and putting this ball nose on.

15:25 [Music] Walk up there now. Yeah, gently. You walk up there gently, mate. Up that up that side. Yeah, it's okay. Just Yeah. Nothing like using set stairs not even fixed in right there so much noise. Set the camera up and speak when I can. Right dows in. Got to put a bit of pressure behind it. Check that line up. Yeah. Nice. It's come up a little bit.

16:45 now. Right, that's all in. Handra rails in. All cleaned up. What I've done, have a look quick look up here. Stairs is safe now. Uh, just put a few fixings in that top nose in there. Uh, I just had to sort of put the, as you can see, very slightly out of square, but not too bad. I'll just run the firm tool in here a little bit to just get that right down. So, uh, next one I'm going to do is fix this, uh, wall string to the wall. Okay, that's that all fixed to the wall. I've used my 10 by M10 by 100. Fisher Fix has got a great fixing back there. Really simple case now. Fitting this bottom bullnose obviously checked this uh, new is plum in both directions. That bottom tread is level in both directions. It's level across there and more or less level and more or less level front to back. We've got to go with sort of the

17:31 happy mediums here. So really all I need to do now is we know we took sort of 5 mil off here. So basically I'll take a measurement from the floor. I'm trying to do this handed. Take a measurement from the floor to the top of that uh housing there. Do the same on this side. Transfer those marks onto this bullnose. trim that down and fit it. Uh, nice and super straightforward. Once that's fitted, it's just a case then of putting this last riser in.

18:28 [Music] Nice. Right. Get under there. Get some witches [Music] in. There we go. Down she comes. [Music] Nice. Right. Screws in [Music] in the wedges are too fat. Need to rip it down a bit. That's better. Let's get it wedged in.

19:39 There we go. [Music] off just the riser in here now. Let's go.

20:29 [Music] Wow. Just these little tread riser wedges in. We fix these to the underside of the tread and the back of the riser. um stops uh it squeaking right that's all in. Look perfect out. Yeah. So happy now that's actually I just cleaned this glue off but basically that's in uh that's the first fix of these stairs done. Just show you what I did under here. Obviously as I said this is fixed all the way up. Yeah. realistically get these wedges in down here, screw the bottom of the riser into the tread, and put these little sort of glue blocks on. Um, if you just see around there, look, a couple of screws. I don't know if you

21:16 can see that. Couple of screws into the corner riser of the bullnose there. Obviously managed to get these wedges in. It's a bit dark here, but but yeah, that's all nice and solid, right? Not that I'm the first person to go up and down it, but the first person to go up it. Always that satisfying maiden voyage. There we go. That's in. So, that's the first fix that stairs done. I won't mess about with the newles. Obviously, we'll wait until it gets all plaster boarded. Um, I'll ask the dot and dabbers. What they'll do is um they'll leave the plaster board over sailing here and I could just trim it off wherever I like when I come to put my aprons in. But um yeah, that's gone in really,

22:01 really well. Actually really pleased with this set of stairs for a new supply that we've not used before. They've gone in really well. One thing I'll quickly mention, I have mentioned it before, uh when it comes to stairwells, the the guys that do the dot and dabbing really do understand that the stairwell has to be a sort of parallel and square shaft. Um so they make a really good job of keeping the walls dead straight and upright. So obviously we can fix our stairs straight against them and everything's still square cuz obviously stairs they don't sort of go although they go from that floor to this floor. They start at this floor here and finish at that floor over there. So potentially the wall could be upright here but not be up right there and it pushes the stairs across. So definitely makes it a much easier job when you know you've got

22:47 tradesmen that are on board tradesmen that are on board with what you're trying to do. And obviously when I put the stud work in here, I left it over enough so that this wall runs all the way through. So, yep, there we go. Um, I don't know till I edit this um how much this footage has come out. It's been a lot of people here. Not the best day to do the stairs, but um we'll see. Um hopefully get the gist of it. I've done stair videos on my channel before. So, there you go. That's that. What I've got to do now is build a little cupboard under here uh to see if we can get a toilet in. So, that's that. That's the little job done. I hope you found it interesting. Thanks for watching.
