How to frame a roof. JACK RAFTERS

[@bapsmcginty4782]

Negative comments? Some people are just never pleased. I could watch this stuff all day. 👏

[@dougieranger]

Me too mate.

[@miken7375]

Great video Robin Watching from USA, would love to see you doing a video explaining the metric tape measure ,no good video anywhere

[@ef7480]

Same with plasterers - they all think they are 'the best' lol

[@oldtoolie7211]

This is from one of your viewers in the US. I fail to understand how anyone can be critical of anything you’ve done so far. I’ve seen most if not all and keep coming back for more because it’s a GOLD MINE of information. I strongly suspect that the vast majority see you as a decent guy trying to provide worthwhile information and are doing it SUCCESSFULLY! I ALWAYS look forward to your videos. In my opinion, you’re WORLD CLASS. Keep up the excellent work!

[@deadlevelwillie]

I was 15 when I was learning this in Ireland 1966 and the longest measuring tape was a Stanley 6' 😀so the hip rafter was measured with pinching rods (2 lengths of 2"x1" roofing batten nailed together with a pointed end towards the ridge),my boss was real old school, how things have changed over the years, I always enjoy watching Robin as I feel I am there doing it as well. He's so easy to follow for someone who wants to do the job correctly, a proper craftsman👍

[@frankie3613]

These videos are like a form of therapy. I can feel my blood pressure and stress levels lower as I watch them.

[@jakestokes2203]

True testament to you as a craftsman Robin is how many carpenters/joiners watch you (I'm another one btw). For us to spend our spare time watching you do what we've been doing all day means you have a gift...total legend IMO 👍

[@ukconstruction]

Hi Jake, I really appreciate the support and encouragement that my counterparts like you and others offer me, thank you for taking the time to watch and comment, hopefully bump into you somewhere!! maybe one of the many trade shows!!!

[@PaulHadley-i3n]

Knowing how to do something correctly and being able to explain how to do something really clearly are two skills that are rare to find in one person. You combine these two skills exceptionally well.

[@Growlerinthebush]

Very interesting video, it was taught in a different way in the army when I worked as a slave to a chippy on a project in Germany but when I did a refresher after discharge even though I already had the qualification. We actually did a practice run on a mock up while on my construction BTEC at Chester College then the roofers used it to practice on. Every cut was by hand as power tools were not as good as they are now back in the 80's. We didn't really touch power tools even on my HND either as it wasn't as much hands on as the BTEC. I was never hands on after that and tended to be management until I left construction in the 90's. After all that I never got to build a hipped roof. ☹

[@wernerhoogeveen8088]

Great to see the methodical approach of the cut work!

[@paulcloona9331]

Brilliant as your videos are always 👌. I never learned the calcs on the diminishing jacks. It's a handy formula to use. I like the method of putting two jacks in the centre of the hip to keep it nice and straight. Nothing like sighting a hip and its arrow straight after jacks are in. I've seen them been loaded up on one side of a hip nailed fully 🙄. Great video. Im waiting patienly for your gazebo build video to start. 😂

[@Doug....]

Lovely job Robin. Liked the maths on that and especially how you used the first 5 jack rafters as templates for the other handed ones. 👍👍👍

[@DP80s]

Thank you for this video. I've heard you mention diminish before but I've struggled to find out the calculations on how to do it. Now you've succinctly laid it out and it's much appreciated. On another note; a grub screw came lose on my router the other day and completely buggered up my hinge jig of yours and the oak door I was working on. Think I was more upset about damaging the jig to be honest. It's worked hard for me over the last few years

[@ukconstruction]

Sorry to hear about the jig!! get some decent 2 part filler and this works great to fill a damaged edge!! Thanks for watching and commenting also!

Hey Robin, I know you've probably had those saw horses for around 20 odd years, but I feel if they were just 200-250 mm taller it would save your back a great deal.

I agree with what you're saying and have mentoned this to Robin, however this video explains to me the reason why Rob prefers a lower bench/horse height.

Amazing video as always. Does the diminishing calculation work if you're working with an irregular hip/out of square hip or is direct measuring the only method in that case. Thanks.

[@TheHairyKarl]

Where did you get the numbers from? Your app or ready reckoner? Eg. 37.5 pitch, oh it’s 1.260 for every metre 😅 thank youuuuuu, love the vids

[@agrennan5411]

How did you work out the 260mm added on to each meter

[@englishrifleman6556]

ohhh some lovely little tips there. Fantastic Thank you

[@wrightwoodwork]

This is a case of being good at theory helps the practical and also having someone help to explain it can help . I must admit I've always measured individually over the years as didn't know how to work out the diminished. Will definitely use . The hip I usually work out the hypotenuse of the plan then use the total rise of common above the sole plate . Along the pitch line to get my angles and length of the hip. Then cut the birds mouth so the hip finishes the correct height to the common rafters. I usually set it it slightly lower so I don't need to do the diehedrial angle. Slightly cheating

[@philmyerscough1]

Great Video, really useful tips. Looking forward to seeing the video with different pitches on the corner, as I'm going to be doing that myself soon. It has steel hips and valleys that tie into a cranked beam though to make it more of a headache for me 😂😂

Hello Robin, seriously a pleasure watching you! I’m a chippy myself however I mainly do fire doors and kitchens. I know you done videos on pricing before but really interested how you price jobs like this, as your efficiency must make the customer think your over priced, but we know you shouldn’t be penalised for being good and quick at a job, just curious:) thanks again

[@ukconstruction]

Hi Martin, thank you for watching and commenting!! I love the fact that I have other experienced Carpenters watching my channel!!!! I do most my work on a price and i make it quite clear to people that they are paying for my labour, my experience, and most of all the profit I need to make to be self employed and pay the tax etc!!! there are some mean spirited people who want to try to work out what you are making based on the time you spent on site and the price paid and I have had that a couple of times before where the customer ha s tried telling me that I earned more than them and that he was a lawyer!!!! and from memory I probably said "and is that not allowed??" I only work for nice people now!!!! Have a great day

[@joshdaviesbespoketimberstr2028]

Thanks for explaining the diminishing technique in full detail Robin, I’ve been wandering how you do that ever since the skill builder hip video you did years ago. Just quickly, do you always set you saw to 45 degrees when cutting along the plumb cut of the jack rafters? Regardless of roof pitch? In this case the plumb cut was 37.5 degrees right?

[@ukconstruction]

Basically yes, the plumb cut will be the same for all rafters in an equal pitch roof, and the saw needs too be set to 45 degrees, this starts to change over 45 degrees and some circular saws cannot cope with that!!!

[@scottnever8732]

Great video. Is there a formulae for the diminishing related to pitch?

[@daihedral9269]

Rafter centres divided by cosine of the pitch. Dead easy.

[@coolerdood2]

I didn’t quite understand the diminish sum, how would you work the same out for a different angle?

[@ukconstruction]

So for every different angle the rafter length is different for every metre of run, (distanced travelled) so if you have an angle that is 1.350m for every metre of run to work out the diminish you do this 1.350 divided by 10 = .1350 now multiply this by your space so for 400 centres multiply by 4= .540mm this is the diminish

[@steveeggleton876]

sois the divide by 4 number based on the spacing of 400

[@ukconstruction]

yes absolutely

[@neil-mv3it]

[@o0o5T3V3o0o]

Do you have to mark on the the top plate where the birds mouth needs to be nailed, Im just wondering how you know exactly where to nail the jack rafters cheers

[@RichieRich845]

👍At 2:13 time was that measurement 400mm and from which side of the timber did you measure from?

[@ukconstruction]

From the left side of the crown so i was effectively marking what would be the longest side of the Jack Rafter, allowing me to mark the overall length on the trestles

[@frankyates7910]

very informative,thanks.

[@ukconstruction]

You're welcome!

[@petef7323]

How did you get 1.260 rafter length while working out the diminish? Tia

[@ukconstruction]

so it is the length per M of run, so the length of the rafter for every M of span for this pitch is say 1260mm then divide this by 10 and if you are using 400 centres multiply by 4 so each rafter would get smaller by 504mm, hope that helps!!

[@danielwhite5456]

Where did .1260 come from pls ?

[@ukconstruction]

It is the measurement of the hypotenuse this is the sloping side of the triangle or the rafter line, if you search this for your pitch or angle it should be easy to find for any angle

The only reason anyone would be negative about your videos is due to ignorance. Plain and simple.

Just for information, the equation to work out your run per meter (in this case 1.260 per Meter of run) is 1 / Cos x Pitch (in Degrees i.e 37.5)
