Installing Herringbone strutting

In depth look at how to measure, mark, cut and fix herringbone strutting

[@gerardrooney4366]

Great video, very informative and you got their attention. Thanks

[@istabraq4]

Great vid 👍

[@MMG_MoonManGuitar]

Thanks for the tips. 👍🏾

[@statesidechippie]

Being spoiled with festool in class! Good job.

[@MrJking84]

They don’t know they’re born mate 🤣

[@mackdenn]

Interesting method, I plan on using a CAD system to calculate the distance and angles and then cut them with my mitre saw. There are lots of ways to accomplish the same thing. Good video and thanks for sharing.

🤣

[@fckmunch]

Would you use this method in 600 centres with 8x2s? And what's the max span of joist before nailing another set?

[@motlatsimolefe1077]

Very smart

[@ImranHussain-tn5xm]

Hi mate I really enjoy the video content about joinery. Is there an email address I could get in touch with the guy teaching

[@stinam]

before you start you need to eye the joists straight and nail a batten on top to keep them in place

[@MrJking84]

This is a very good point that was missed in this video as was concentrating on the methods of cutting the herringbone. Will update the video at some point to reflect this as it’s an important point to ensure joists are straight 👍

[@jonny69rotten]

informative video, is there a minimum thickness for the noggings?

[@Scribe3168]

Yeah just become a banker

[@MrJking84]

38mm pal

[@DanielJohnston-uz6yl]

Hi, what size timber do you typically use for the strutting?

[@DanielJohnston-uz6yl]

Also is one row across the middle enough, is there a rule of thumb dependent on the joist span

[@MrJking84]

2” x 2” something around this size

[@pasla101]

Yes all apprentices learn the principle of herring bone strutting as you will probably never use it . Nearly 99% of strutting will be solid strutting. I just hope colleges are teaching I joists as well and not just dated solid joists.

[@MrJking84]

We certainly are pal 👍

[@therabman_5606]

I learned this technique 17 years ago when I was in college… have used it twice that whole time, but I’m certainly glad I know it

[@sionatko]

Herring bone strutting is so much better than solid strutting in regards to weight dispersion. I am not a fan of solid strutting, there will be far less squeaks with herring bone.

[@AlwaysHopeful87]

1. Mark/Chalk/Pin a line for the row of the struts on top of the joists along the floor. The line should be parallel to an edge. The center of the row of joists is recommended. 2. Measure the height of the floor joist or desired dimension. (225mm) 3. Take that measurement and “take off” about 10mm, (215mm), and Mark/Chalk/Pin another line parallel to the previous line. 4. This creates a horizontal rectangle on top of the joists that is like the vertical rectangle between the joists. 5. Lay the strutting lumber on top of the horizontal rectangle, align the rough cut strut’s outside edges with the marks and pencil it from underneath on both sides. 6. Cut the struts by hand or a miter saw. 7. While the bones are loose, start the nail or screw. 8. Fasten the bone to the joist. 9. Optional, fasten the 2 bones at their center.

Can I just ask when you would use herringbone rather than regular noggin? What is the reason for herringbone?

[@MrJking84]

Solid noggins can occasionally shrink which could lead to the joist twisting. Whereas the herringbone braces long to long. I’ve done herringbone before in the joists above an restaurant kitchen where moisture content will be minimal

[@paulyoull5472]

Thanks for the reply. I was aware of it, but never seen it done. Great technique too. Just a shame your students aren’t as enthusiastic🤣🤣🤣

[@MrJking84]

🤣 They’re buzzing inside 🙈

[@TheToolnut]

@@paulyoull5472 Also herringbone is great for running services, the Sparks and plumbers love it, 👍 😁🔨 🇮🇪

[@paulyoull5472]

Cheers mate.

[@davidwhyte2620]

why not use a framing square to get the length and the angle

[@MrJking84]

Mark the first then last joist and use a chalk line

[@peterryan7340]

Screw into position? Why not nails?

[@MrJking84]

We’re a college buddy, everything we do has to come back apart. Do this for ease 👍

[@ImranHussain-tn5xm]

Hi mate I really enjoy the videos on joinery. Who is this guy and does he have a email address for me to get in touch with him

[@antonyporter5045]

self cutting/drilling screws..............no pilot hole needed

[@huejanus5505]

Solid blocking would go much faster, be stronger, and would square the floor joists up better than this method.

[@gavincollins9376]

Hence why it's seldom used nowadays!.....

[@TheToolnut]

No, herringbone is stronger and allows for movement in the joists due to shrinkage. Much better for services too. The reason it isn't very common now is that most carpenters don't know how to fit it and it takes longer. It doesn't fit with the crash, bang and wallop culture.

[@stevehallam6495]

Hue Incorrect ......strange but true herringbone strutting is stronger than solid bridging. I have had arguments about this where management think solid has to be the strongest rather than a couple of bits of 38 x 38 but its the cross triangular bracing effect that spreads any point load to adjacent joists. It functions best where the joist depth is closely matched to the size of the centres as this makes the struts closest to 45 degree.
