Robin Clevett loves a scarf joint, and in this video, he shows you how to create a strong one.
Roger & Robin also have an epic fight, see who wins this battle.
We'll soon have more woodworking tips, carpentry tutorials, and hacks.
__________________________________
A scarf joint is a woodworking technique that combines two pieces of timber end to end, creating a single, longer piece of wood. This joint is particularly valuable in carpentry when the required length of timber exceeds the available length of a single piece or when it's necessary to repair or extend an existing beam.
The scarf joint cuts the ends of the timber pieces at an angle, creating matching, sloping surfaces that are then glued or fixed together. The angle of the cut can vary, but it's typically between 30 to 60 degrees. There are various types of scarf joints, such as the plain scarf, which is a simple, straight cut, or more complex versions like the keyed or wedged scarf, which include additional features to increase the strength and stability of the joint.
Carpenters use scarf joints because they distribute the stress more evenly along the length of the joint compared to a simple butt joint, where the ends are merely butted together. This makes the scarf joint much stronger and more durable, especially when the timber is under tension or bending forces. In structural applications, such as roofing or long beams, the strength provided by a well-made scarf joint is crucial.
Moreover, the scarf joint is often preferred for aesthetic reasons. The angled cut can be made to blend smoothly into the surrounding wood, making the joint less noticeable. This is particularly important in visible structures, where the finish and appearance are key considerations.

Hi By
This guy is cool
I hope he knows Christ as his saviour.
If you like that saw, you should try the Dewalt 60 volt circular saw and 60 volt worm drive saw. They are beasts.
Ok
@@brucecummings514 OMG why are you bringing Religion into these comments. This is not a place to proselytize! Unless this was a religious posting which it is not.
I'm probably never going to need to construct a scarf joint...but my life feels richer having watched you explain and create this! Thank you.
It was nice, wasn't it? Now watch this one for a creamy ending: ua-cam.com/video/0p_jCW5UcI0/v-deo.html
@@ljprep6250 😂😂😂
Me neither.
Still waiting for Roger to do a video about flies getting in my flapper!
This is the one man you need to listen to. Not a single word of nonsense talk, just the real essentials are shown.
Beautiful. I love when a pro is not selfish and enjoys sharing his hard earned knowledge with us dummies. Thank you so much.
You got that right. I still don't know how that joint holds so well.
I’m not telling you. Before we know it, you’ll know as much as me.
I can only wonder why people would thumb this down ? The man is a master craftsman a dying breed in today Cowboys masquerading as skilled builders 🤔
Because most people are miserable P.O.S's and they aren't happy unless they're talking shit to others from behind their warm safe computer screen.
Stupid is as stupid does. Just takes 1 mouthbreather to start it.
It's the Cowboys giving the thumbs down.
Because this is an advertisement for HiKoki. If this were a demonstration on how to make a scarf joint, he would have used non specific tools. (How much time did he spend on telling you about the hand saw he used? - about the battery life? about how great it is over another saw?).
Ten Millimeter Actually he didn’t mention how great it was compared to any other saw. He did mention how convenient it is to have a battery powered saw instead of a corded one due to the fact that some job sights won’t have power. That’s factual. Obviously you don’t understand how YT works. Some times content creators do short product spots to get their video sponsored. Nothing wrong with that.
Robin, your style is wonderful. I learned more from in you in thirteen minutes than in thirty years of hacking around. I never thought to sneak up to the line with the circular saw and finish with the hand saw - two seconds and look at the cleanliness of that cut. You're a natural craftsman and a natural teacher and so articulate! Thank you for sharing your knowledge with us. And who doesn't love a scarf joint? Now, not only can I visualize with exactness what a scarf joint looks like, I could (in a passable imitation) come up with one when I needed it. So many working tips in so short a video. Amazing.
1st class trades man, a dying breed. It took me 6 years to become a carpenter doing all of this and more in Ireland,every day I still learn something new. Now everybody wants to be in IT or some other brain numing job ,No trades people anymore only people who think they are, and charge top money for rubbish workmanship.
Good on ya mate keep up the fantastic work.
Anyone else like me watching a video of something that's of no interest to me but I'm so fastinated in the skill of the bloke that I can't help but watch haha.
in a word, yes
I laughed when I saw your comment because that's exactly what I was doing. He is an excellent teacher.
Yes!
Andy Thurlow yes
Yup, watching an experienced and skilled tradesmen is always fascinating.
I’m an retired DIY home owner who will never in my lifetime have the need to build one of these joints but it’s so beautiful I’m going to buy a piece of lumber and learn to do it. I can see how to use this as a decorative piece as well . Thanks so much for the tutorial ! Mikey
That is a true compliment..... I for one appreciate it!
Don't rule it out. I'm a DIY guy myself and I'm sure I will need it some time.
It's good to see someone using a scarf joint! not common today or used due to the introduction of galvanised plates! I was recently chatting to a newly qualified chippy who, when speaking to him, said he'd never been taught or even heard of a scarf joint and certainly hadn't been shown one by his college on his apprenticeship!!
That's a shame the apprentices are not seeing these joints at colleges
That was very interesting and educational to boot ! I'm a 75 yr old Canadian ex building contractor /solid wood furniture maker. Had my shop business for 10 years building custom furniture and later , built custom homes for 36 yrs . I've used a scarf joint a few times but just realized that I wasn't doing it properly until now :((. I never used the wedges !! That makes such good sense to be able to close that joint so well . I did cut them accurately though , which definitely helped them to be solid . Good videos !
Thanks Ed nice comment
@@ukconstructionAnother super tutorial Robin. So is this being used here for a ridge beam or ridge board? The beam as I understand it is a structural component. If it is for a beam, does this mean it could be used in place of a long glulam beam or steal for instance supported at both gable ends?
Many thanks Robin.
Wow! This was amazing! You can tell this guy knows his business inside out, the way he talks about the processes is so natural! I would love to work for this chap!
Seriously impressed with the professionalism of the guys on this channel.
These guys know their stuff, they really do.
Excellent series.
Just found your channel - brilliant!!I’ve framed for 40 years and never considered doing that... I am familiar with the joint from Japanese woodworking and heavy timber framing - just never considered it for a hip/valley or ridge. Even old dogs can learn new tricks!
I've been in it for most life and never did it that way, … Impressive. Man knows his stuff.
My father was a master carpenter and I helped him make scarf joints when I was a kid But he never explained how he did it. That was 50 years ago and He's gone now Some times I wish either I was older when helping or that He explained it like you did. Almost all my adult life He was a construction supervisor with a major construction company so by the time I was old enough to understand He wasn't hands on anymore. PS He was able to do this with an 8th grade education from a one room school in rural West Virginia. Now kids graduate high school and aren't sure which bathroom to use.
@ You got that right. When my father retired I told him in a sense he was lucky, Being a child of the depression and 1 of ten mouths to feed, being drafted right before the Korean war broke out, he was puzzled by my statement . I told him he was hired to do a job in a time in history when your ability was what counted. Today to be hired to his job requires a college degree.
@@johnkendall6962 i know hundred romanians who do this here in Uk only by few nvq qualifications
if you learn the right way and keep repeating till you succeed
I can give you my saw 4 ft for free to test it. Miter Saw is an old idea because has just about 1 ft cut and cannot be used on boards. It shall be retired. I invented a "Parallel Guided Power Saw" which can be seen on you tube under this name. My saw can cut up to 18 ft or more. Look at my saw and let me know what you think. My saw may replaced miter saw, table saw, and router table. It can carry also grinders, drills press, hand saw and more.
you are comparing two different things. a degree is suppose to teach you the physics, how it works, why it works, the forces at work etc.. real life experiences / hands on training teach you how to apply that knowledge and how to physically get it built.
Idiots today call it "Progress".
I’m not a carpenter or much of a diy person but watched this video and thought it was amazing. A very strong joint and you made it sound interesting during the process.
Thanks for taking the time to show us this.

38 year old master mason and carpenter from Alabama. Very impressed! I subscribed. 👍
From the start, Ryan was very helpful and is continuing to be helpful about his ua-cam.com/users/postUgkxGqOCINHE0Z0E5gxzSdNi9NWGugRY5Hm2 Plans . Also, they have answered all the questions I have asked & I got outstanding support from his My Shed Plans full package.
Hi I'm that Roger Busy Bee from that Skill Builder channel and there's nothing I like more than a good joint.
Thanks!
Thank you Grace
I'm a joiner and seen a few different scarf joints but none like this very impressive!
As a joiner I always appreciate seeing other craftsmen at work. Really nice job 👍
Brilliant! I am an amateur woodworker, I could not have learned how to make a scarf joint on my own. Good visuals.
Absolutely, these techniques goes back hundreds of years..before metal fixings and limited tools.
What’s just as impressive is how he gets that - off saw spot on the job. I have a corded 7-1/4” saw (similar) but can never get the blade exactly where I want it.
AWESOME!! I never knew about this type of scarf joint. we used a "scarf joint" back in the day for trim, just a simple 45 degree overlap joint, we do not use that anymore. This is NOT that scarf joint, I can't remember who instructed me incorrectly on it, but thank you for educating me properly on this. Its people like you that make the world a better place. Thank You
Technically, a scarf joint is any sort of angled lap that joins two timbers lengthwise, so you're right think of those ones of yours that way even if they weren't structural.
So for example you'll sometimes see simple glued scarfs when repairing wooden boat frames and strakes, where the two pieces are cut at a common angle and glued up with epoxy. This is an extreme case in terms of both simplicity and total reliance on adhesion for its strength, so the scarf pitch is extremely shallow, typically 1:12, and it's done parallel to the wide face of the board, both to maximize contact surface and to align with springing forces. The ends may be slightly stepped for the sake of appearance. You won't know that these are scarfs because the angled faces will be hidden.
At the opposite extreme are the many variations of scarf joints in traditional Japanese joinery. There may be multiple steps, and the ends may be undercut or fingered, for example, all in an effort to hold the joint tight. Fingered joints must be drawn tight with wedges, but on rare occasions you'll see the unfingered kind so precisely fitted that they're simply driven together. I expect that unwedged scarfs are used in applications where the pieces are held in place by some other means as well.
I work in a boat building school. We call a straight 1:12 diagonal joint a scarf (or scarph); what he first laid out a stepped scarf, and this joint is a wedged or pegged stepped scarf.
Surprise! I expected just another ad and demonstration but listening to how he talks and seeing how he works tell me that he is an expert. Well done! And I learned about the tools and a scarf joint.
I appreciate you slowing down the job and taking the time to teach others! Cheers mate
Definitely a great, great video, it is the first video explaining in detail how to do it. Thank you.
I can tell you this... Brits can carpenter too! Lol
I like the fact that my one favorite channels support another one of my favorite channels. I learn so much from both of these channels
I clicked on this because as a trim Carpenter I do a lot of scarf joints. Not the same but I still learned something today. Thanks for that.
I'm a trim carpenter as well..just curious, what do you usually have to scarf joint ?
@@michaeljohnson6649 anything that I install that's not long enough for my run. Crown, base, jams, shoe, casing... I never use butt joints and I learned not all that long ago to match the grains if possible. Makes for a much more professional finish.
@@russwollet8998 ok cool..yea I never but joint either..usually mitered 22.5 and yes I always match grain or cut out of the same piece around corners so the grain flows..looks 👌
I’ve been a carpenter/contractor for 39 years. Great demo, great result. Congrats. And I see a beautiful , challenging and fun project in the background. I’m Dave Heitman dba Dave the Carpenter in Omaha Nebraska. USA. I’m 69 and can outwork guys/girls 25 years younger. I plan to make sawdust till I can’t walk. I’m still driven by the burning desire to be independent. We are lucky men , are we not?.....to be free, outdoors much of the time, trusted to build someone’s dream. My clients become friends. I’ve met wonderful people. Only 3 assholes in 39 years. Measure twice.........and next time when stick fighting...go for the nads.
Love your stuff Robin. You have shown me what I should have done with my life. Although I am now retired, I am still fascinated with the production and manipulation of structural timber. The skills and beauty of what you do inspires me to learn more and more. As a retired teacher, ex structural engineer and itinerant musician I am so glad to be able to learn from guys like you about how things are done properly with skill and pride.
Love this video, watched it about 4 times now to make sure I remember how this is done. I'm a young self employed builder and buzzing to find a job where I can use this. Keep it up buddy, love the work!!
Another great video I love watching these as I spent 4 years building timber framed houses and other jobs with my step dad. been a lot of years now since I worked in the industry but still massively appreciate the workmanship of woodwork.
Been building since the 80's. I was never taught this. Wonderful stuff!
A thoroughly enjoyable video from a guy who actually works at carpentry/joinery.
I've been a remodeling contractor for 37 years and never seen this done before ! I will use this
technique when I build by barn great ridge beam, Good job young man !! we can always learn new tricks !!
I've watched this video many times. I build things. My wife does not, but even she likes watching this video. Attaching two long boards with now screws. That is genius. From all of us in the USA, well done Sir. We thank you.
Great master carpenter. I'm not even addressing these framing right now - just fun to watch. Better than t.v. too! I just like watching a skilled craftsman at work - I find it simply entertaining to learn and watch others enjoy their work and craft. Plus, what a pleasant, clear, and helpful human being! Thank you!! And yes ... I subscribed.
It's awesome watching a real master craftsman work. He made it look so easy.
I like that you took time to predrill that wedge, most people would just run that screw in and hope it doesn't split
As DIY gimp myself, that used to be me, until one day it passed me off so bad I googled it and then was like, "what a colossal moron I am", now have a twin set up, one to drill one to drive. Its this kinda stuff they don't teach in school anymore.
any self respecting carpenter knows to predrill
My dear departed Dad used to say “if you can’t swing on it, it’s not good enough”.... you easily passed the test. Brilliant demonstration, I’ve learnt something new, cheers.
Wow. Thanks. I've done a lot of framing. Never seen a a scarf joint like that. Brilliant. You are a true craftsman. There are not very many people I would let work on my personal house and outbuildings, but you are one.
You are a very interesting person to listen to and watch. And of course you do great work. I learned something new today watching your channel. Thank you Sir
I didn't realize there is still a craftsman in the world today. Well Done!
im 22 and im a carpenter. im studying my building course and thought i got off track with my study but honestly i didn't when it comes to being a carpenter. great videos and great work. you remind me of my Cert Iv teacher, he is so knowledgeable and a great teacher. Thanks Andy Finlay and skill builders
Hahahaha
Nice. I hope you stuck with it, I started young and now with 27 years experience, I wouldn't even think of going back and choosing another profession... Always in demand, everywhere. And so much fun!
Since youtube has recommended me this video no less than 2.3 trillion times, I think I’ll finally give it a watch
I did not know what a scarf joint was, so I googled it and ended up here. It was a VERY enjoyable lesson! Thank you! Don't know that I will ever need one, but if I do, I will remember you and have saved the link to your lesson. All the best - John. PS, congrats on winning the balance battle! 👏
A skilled artisan with a circular saw you make it look easy.
Hello! I’m from Buckinghamshire. After 12 years physically learning, and studying. I’ve just started my own building company for the first time! Loved your videos in MK dons! All my work is word of mouth. Loving every minute. Thanks for the videos keep them coming.
Blimey, you Brits do have a way with words and wood ! ! ! This is an excellent explanation of how a scarf joint works, and with a Damn Nice Cordless Saw ! ! !
was it; this joint is almost done ?
As a frame carpenter in the USA for 35+yrs I have never seen that joint. Great video I will try this the next time I need a extra long hip or ridge. Thanks
Great go for it, thanks for taking the time to watch
I m 71 and I learns something that I had never had idea how smart it is thank you Tom.
Very useful and practical video to demystify the scarf joint, along with entertainment. Good effort.
Thanks David
That fight at the end was amazing guys! thanks for making me laugh!
That was cool,I have been a carpenter for 40 yrs and have never seen this done,but will try it the first chance I get
They say you're never too old to learn something new. I've been in construction since 1974 and I learned something I didn't know before. I done a lot if different Joining but nothing like the scarf joint. Thank you
Wow. Thanks for sharing that piece of technique to people. Iam a builder and have always been puzzled by how this joint is made. Now I realise its one of the strongest yet aesthetically pleasing joint. Your technique doesn't even require alot of nailing or bolting.
Thanks again for sharing this old technique to most of us younger generation of builders.
Looking forward to another carpentry technique.
Never seen that joint before. Very nicely explained.
Technically, it is a Keyed Scarf Joint
Look upo Japanese joinery... that do some crazy strong joints... but they are so overly complicated.
Lovely joint, well executed. Makes me wish I'd been in the construction industry watching work like that but at 62 I'm going to have to settle for being a hobby woodworker but still, I can get my construction fix from your vids, cheers guy's.
1st joint I scarfed was in highschool when I got pulled over.
lol
Fuck I did the same thing in junior high school
That was funny I wished I'd thought of that a long time ago
small town Northern Ontario Canada 🇨🇦👍
Got me with that one haha!
🤣
Nice to see a framer who knows his trade.
Robin I've just subscribed after watching you doing a scarf joint I've been a joiner and cabinetmaker for 50 years and use my festool saw like you for pocket cutting and thought I was good as you but watching you perform magic with hand saw and portable saw and so quick you are a truly brilliant craftsman and explain in simple terms and so quick I'm now going through all your videos keep making them .
Well now, that was a pleasure to watch, lovely craftsmanship, thank you.
Dang! You got me at the end.
That is not what I've ever called a scarf joint but I have seen it in Japanese construction.
Good clip! Thanks.
UA-cam the way it should be! Stumbled upon this gem. Thanks you!!
he works smoothly.
We learned another technique in wood work.
Big thanks to you.
At the end of a story its fun.
Their funny jokes connected to their work illustrating how hard the join timber when loaded with two persons.
Why anybody gives these videos a thumbs down is beyond me. Well presented by a real craftsman.
some people don't like the product placement
@@SkillBuilder Some people are just idiots, what's that got to do with the content.
The banter is just right the skill is higher than everest, thanks for the knowledge!
Just such beautiful craftsmanship and amazing knowledge, Once again thank you for the upload it's great to keep learning new things 👍
Quality, informative stuff, many thanks. Robin of Loxley taking on Lord Bisby of Rogershire at the end was good too!
Scarf joints are tough very long lasting and it seems few carpenters know how to do this anymore.
This man is brilliant haven't seen very many guys use scarf joints in years surr makes me appreciate our old time ways they work plain and simple!!
The funny thing is that since making this video we have met several carpenters who use them on a fairly regular basis but steel ridge beams have become so popular that the poor old scarf may end up on the endangered species list.
Great explanation and video. I sent it to my son Sam & fiancé Ella in Melbourne. To my surprise he said they knew you and you did a brilliant job fitting bedroom windows in Waterloo St. Brighton and lent him your Festool plunge saw. Small world. Thanks for the videos, keep them coming.
Nice to see someone who knows what their doing
they're
It is not just the wonderful skills that are demonstrated here that makes this a great video - It is also the speed at which you work, each stage is clearly explained and humour as well ! 5Stars
Thanks Terry
Good instruction! roof carpentry one of my favourite studies and practice for many years
im a carpenter , well was im a site agent now but we used to use this joint all the time for ridge and hips. Great to see them still being used. Had a couple of apprentices on site the other day and im shocked at the stuff they dont teach them anymore
Watched this video a few times... and made a scarf joint. Mine was not perfect, but with some fasteners... it is working perfectly.
Thanks
Fantastic! It is good fun to try there things and your next one will be even better.
That's how a pro does it👍 top stuff you make a hard joint look so simple great stuff best video yet guys
Mark Hep this guy is a fraud, he is a paid advertiser !
@@paulorchard7960 may be but he is good at them joints I have a few videos on mine brickwork mainly would like a few views love making the videos see what you think mate 👍
@@paulorchard7960 Hi Paul
Why a fraud?
He is using the tools and commenting on them. Hikoki has zilch influence on his findings and has agreed to our terms and conditions which give our presenters freedom to say what they think. He showed you his old Hitachi tools which he has used for years. He is a fan of the old Hitachi and even met the engineers to talk about the new design.
@@paulorchard7960 have you watched anything on UA-cam before? Ever heard of monetising? I don't see anywhere where he says you have to use their tools to get the result.
awesome video, glad you found something to do after "The Grand Tour" wrapped
Love your attitude, thanks for the 'new' knowledge on a great old joint
I saw a gazebo in Man-O-War Cay back in the 80's that the local shipwrights had built using this joint extensively (but no wedges, clearly very skilled carpenters) I never had the skills to duplicate their work and had no idea what it was called
Wedges!!!! What a clever hack Thanks. .
Last made a wedged scarf joint 50 years ago at school and I think you do it rather better . Thank you I enjoyed that
It's the best bit of joinery I've seen for years.
You should see the video's of the japanese carpenters doing them. They are widely used in their temples etc
@@Adsjabo Japanesse wood working skills are simply amazing.
You can’t be a tradesman - you are measuring things, taking your time and using the correct tools for the job. Great video!
I don't know how I got here but I couldn't stop watching. Nice job.
UA-cam algorithms are obscure - don't know what it was in my recommended either. Sure I seen this guy raving 30 years ago.
If you know anything about working with timber....you aren't giving this a thumbs down.
Excellent instruction, wish my teachers had been as clear.
I will never need to make this joint nor likely ever have the skill, but watched with fascination anyway, at an expert making something ingenious look effortless. Thank you.
Great job across the pond. Only thing s do different is instead of a 90 degree cut , I angle back 5 degrees so it locks under..love the channel
Hi Joe
I like that 5 degree set back. I have seen that done in old oak barns over here.
Right on...it’s no extra work, why not use geometry to your advantage.
I was just thinking that myself!
I'm sorry, somebody help me with this. I've built a lot of homes, done a lot of remodels and never knew what a scarf joint was. I dare say if I ever took this much time joining a ridge or hip rather than butting split at a rafter, I'd of been fired as an apprentice. Someone tell me why this is necessary.
If it's for a ridge board and not a ridge beam, then why bother? Time is money. I don't get it.....
@@crforfreedom7407 Ignorance is bliss. Your mentality is common in America, and has been for some time. When I see pictures of the devastation after, say, a hurricane, I see construction methods that make me think of third world technology. Cheap, fast, and flimsy. Plywood, studding and plasterboard gets the 'job' done fast and cheap. This video is about how to do a job that will last longer than a lifetime.
I'd love to be an apprentice for a few weeks (reconstructed 3 houses, but there is nothing like seeing a master at work)
You’re a natural on camera , great video , 👍
This lad is what you call in the trade as a top joiner keep up the videos there great 👍
Great video. Fascinating content. I've been in construction all my life (65 years) and I've never seen this joint used. I'm subscribing to see more. Thanks for sharing.
I don't think it can be done better way it's just great
I'm going to create a problem that requires a scarf joint just so I can look awesome when I show people.
Idiot
I get your sense of humor and thought it funny 😄
@@keredrellit3992 Hahaha! Cheers, man👍😁
You'll be loved by all
Same. Shameless…
Great video Robin, thank you for sharing! All of the sudden I miss "stick framing", that is difficult to do.
I love this framing joint and it makes me want to work in my shop making all sorts of joints for furniture...some day
Hey Roger .... good to hear you on the radio yesterday .... youve hit the big time!
Outstanding mate. Been around carpentry here and there all my life and never seen this used in the field. Knew about scarf joints from old carpentry books, but they were different - more of a V shape where you overlay two boards and set your saw a tad deeper to mark the cut on the underlying board while cutting the top one. Currently renovating a 115 year old house on the Washington State USA coast and the long 2x4 ridge pieces are butted square and not even on rafter spacing.
First time viewer. Very nice! Great craftsmanship - I’ll watch more of your videos.
Bravo, love to see un maestro at his craft.
Excellent video! Simple repetition with perfect planning and executed flawlessly by Robin and Roger. Luckily we don't need to do major roof work on our reno but good to see the process on this anyway. Hikoki tools look excellent also.
I am amazed at the amount of carpenters Ive worked with in the last 20 years roofing and timber framing that don't know how to cut a scarf joint. Should be common place when roofing joining ridge beams. Great vid, liked the wedge technique. Only used it a couple of times but well worth the end result.
