Thank you so much for this video. It was the actual cutting of the scarf joint with a Skil saw that was tripping me up. Now that I’ve seen you do it, it is so obvious! Hahaha!
Definitely interesting. It makes more sense to me for this joint to be used in timber framing or when ordering longer material is not possible or feasible. Here in the states, we would order engineered lumber in the length we need, so that the member can be one length. Also, when hand framing rafters with a ridge board, the ridge is actually structural, IF there are no collar ties to keep the walls at the eaves from spreading.
Thank you for your comment. You are right a scarf joint is not a structural joint so for example if I was framing out floor and the joists were too short, I would have to either use a steel to break up the overall span of the floor or use a glulam beam ie engineered beams. In this case the rafters are picking up the ridge and I also used collar ties and wind bracing to stop any movement.
At 4:00 how do you determine what is the distance of the edge of the line to the start point diagonal line. Is equal, maybe, to the thickness of the board? Thanks a lot. I got the answer at 5:28. Τhe mark at the point of intersection of the beginning of the diagonal line and the inner mark.
Nice work. That looks like all wood construction. Do you have a problem with termites there, I assume somewhere in England. Where I live if I used that much wood for structural posts termites would bore thru in a couple of months.
@@trebledog Thank you for your positive comment. Luckily enough in the UK we don’t have that problem. However if you watch some of my other videos. I sit the entire timber frame on Groundscrews. This makes the whole structure elevated and protected from dampness and some insects. Have a great start to your 2025. 👍🏻
If You Tubers are filming these types of technics they should use a narrow point Sharpie as we can't see the lines they draw. It is now like drawing an a chalk border in school with your finger.
It is difficult to see the lines because I’m using a 6h pencil. Also I don’t have a camera many to help get the close up shots I need. However you can see the end result. 😉
Ok - it is purely a mechanical joint that interlocks to hold it together. The question is why don't you put construction adhesive in the joint then put at least 2 cross dowels (one on each side of the wedge) to keep it together. They can be full wood dowels or big full length screws - something to keep them together. Everyone (including you) know that wood will continue to dry and shrink and the joint will loosen up because there is nothing to keep it together (see above to prevent this). The wedge will do the same.
3:35 "square of these edges [...] You can see what I'm doing" No, we _can't_ see what you're doing. At which point do we need to square off? Does it not matter?
Why on earth didn't you show us the most interesting and important part, which was to show the mating piece going together and explain those wedges you assumed we all knew and understood? This was a waste of my time watching. Sorry, you seem to be knowledgeable and all but failed to complete the instructions.
Never start a saw while it’s in the work. You did a plunge cut then stopped the saw, then started it back up without taking it out of the work. Big no no.
Please edit your videos to speed up the process. Also your wearing ear protection but not eye protection. You can still build minus hearing but really hard minus eyesight.
Any reason behind this? Carpenters have used these joints for generations. When installed correctly and where appropriate there’s nothing wrong with the joint. You should however never use this joint on floor joists.
@@claytoncarpentry618 mainly because it's not as strong as a board that was never cut. Wood expands and contracts and if it does this could come apart. The reason it shouldn't be used on floor joists is because it isn't as strong.
They're not used on joists. He said in the beginning its only used where the board is picked up by others. This technique is hundreds of years old and almost all centuries old buildings will have one or more of them in it.
@@bushratbeachbum I understand that but the REASON why they aren't used on joists is the same reason it shouldn't be used on roofs...it's not as strong.
@@realtyrocks1969 see my comment above and the explanation given by the person making the splice. If you had experience in woodwork you would understand where it's safe to use and where it isn't.

used your technique a lot. just finished a 12X24 barn addition with it well done

Perfect joinery for extending the ridge board ! Once you connect your rafters that joint will never pull apart!
Some people say 3x the width , some people say 5x the width.
We go 4x just to piss everyone off.
👍😆🔨🇮🇪
I tried my first one today, very rough, after watching yours, I want to go again :) thanks!!

I’ve been a turnkey homebuilder for 42 years. I work with my framing crew. I’ve never had to do anything like this.
We missed the main teaching putting it together 😮
There are different types of scarf joint for various structural applications. To find out more get yourself a decent book on wooden boatbuilding.
Great job mate
Cheers matey! 👍🏻
im no pro but i love how the decision to cut the less pretty grain pattern was integral to the overall measurements. thats classy alright lol.
Outstanding Sir, 👍🔨🇮🇪
Thanks matey! 👍🏻
Awesome joint.
Thank you! Cheers!
There are other scarf joints arent there? Are there any that work well under compression?
You don't lag bolt them together from top to bottom?
You do?
Two *what* wedges?
Might want to consider using safety glasses
Take a trip to Asia my friend... you've been brought up wrapped in cotton wool 💃
How do you find the DeWalt flexvolt circ saw?
Love it mate 👍🏻 I’ve constructed four large European Oak balconies using the dewalt and I couldn’t fault it.
What model is the saw please? Thanks

Hoped he would have shown it put together. There has to be a better video than this.
Good stuf👍
Thank you 🙏
hammer on your left side...you a switch hitter? good presentation mate. well done
Can you make it today? I have things to do.
@@MikeM-sc4tx 🤣🤣
Thank you video,+1 subscribe👍
Should have done with with a pen so we could see the lines !
I have got so many comments about this. I will make another video.
a long way round easy way cut 75 deg cut 2 haunches top and bottom cut a sq out of the centre 25mm x25mm cut two wedges and lock in
Thanks for sharing

No, we _can't_ see what you're doing. At which point do we need to square off? Does it not matter?
Are those beats? 😂
Where is your eye protection man?
@@deansenecal5023 my glasses you mean. 😉
Talkative
🤘🏻🙂
Cheers matey! 👍🏻
I don't get how this isn't structural ! Roof ridge...would think the strength of this quite important. But then I'm not a builder of roofs!
A scarf joint should be a 1:10 ratio
Get a blade with a higher tooth count for your circular saw and you won’t have to use the handsaw so much to smooth it out.
That and have a sharp chisel at the ready, 👍🔨🇮🇪
The hand saw was taking out the radius left by the circular blade, not smoothing.
When people going to wake up an use feet and inches.
How to cut “Half a Scarf joint”
No assembly
Very disappointing 👎🏻
🤔 maybe I’m daft but you can see the full joint at the end of the video.
@@claytoncarpentry618 no you’re not daft but would be nice to see it assembled don’t you think 🤔❤️
@@jamiekent1970 You do mean "see assembly " correct?
Not enough
Can you please elaborate on this comment?

I would not buy a house that used this technique on a load baring roof or floor joist.
