- BRICKLAYING - How to cut VOUSSOIRS
When building a brick arch and you want all your mortar joints to be the same size, you will need to cut voussoirs. This is the name for a cut brick in an arch, bulls eye or similar radius brickwork.
This video will explain all the steps involved in cutting voussoirs. Hope you enjoy 😁👍

The title of the video is "How to cut VOUSSOIRS" and you showed us everything apart from how to cut a voussoir!
I'm pretty sure that fitting and measuring, placing and the logic behind making the entire arch trumps cutting a bloody piece of brick.
Alin Trinca it’s a good video but I also wanted to see him actually cut the brick. I assume he’s doing it with a petrol saw but I wondered if there was any other trick. Like, maybe he just shaped those ones we see with a brick hammer! 🤣we may never know….
@@mankillsquare Well, actually you do see that the bricks are wet. That means he used a diamond blade on a water fed saw to limit the amount of dust. However, I think he has a portable cutting station or a pump fed saw cause otherwise it requires two people to have the bricks cut clean and correctly.
Alin Trinca Well, the bricks are wet. Which means the bricks are wet.
@@AlinTrinca Not for me. I know how to measure things, I've no experience cutting brick.
Hi love the video had to do voussoir arches on my level three many years ago. You should do an extra video showing the process of actually cutting the brick. Because that can be a right pain.
Yeah, this should be renamed to how to measure voussoirs.
CUT ALREADY SHOW CUTS
Bricks layed wages paid. These videos are great to watch in isolation keep them coming👍
Great video: how did you actually cut them. Would have been much more helpful.
👍
Same. Main reason I watched was to see how to cut thin slices off of bricks. He skipped that bit :(. I'm guessing he probably has a fancy table saw setup with water and everything though. I'm trying to do this with a grinder and not sure if it's possible.
@@ashh3051 it is , on a flat surface place the intended voussoir place another brick about a foot away put a batten of wood on top of bricks put your foot on the batten and use your weight to hold them down and cut away , i think you get the picture .
Heard you count 22, was always taught number of voussoirs in an arch should be odd ,( wherever possible) so the odd one is
the key brick, wich sits over the arch centre line.
youve helped to refresh my
memory, I had to cut some
blue bricks around the top
of a well, kept the 65mm
face and and reduced the end by 10mm each side, traced them round ,
traced the round, worked
great, you can get round
A lot just using this basic
method.
From fellow BRICKLAYER
👍
I agree should have odd number so you have a key brick
Good instruction. Thanks for the clarity
Brother, you are top-notch for taking the time to make this and slapping some humor in there for good measure. Appreciate you 🤙🏾
Well done! I haven’t used this method in over 30 years! Have some shallow arches to build on job I’m doing now so thanks for the refresh. Will also send the base off to the joiner to make the arch so two jobs in one!
Thanks for a great series of informative videos.
I’m a hobby bricky, my first project was for my parents a very long time ago when I was fourteen, it was a wall following the curvature of a winding brick path. Lots of trial and error involved!
Later on I extended the wall and included an arch leading to the orchard, it’s a big garden. Calculating the taper on the bricks took a bit of time, hence I was interested in your video on the subject. I just called the two main dimensions: inside radius and outside radius. It’s nice to know the proper names.
After my parent’s passing, the house was sold to a building inspector who without knowing who’d built the various projects including the lower portion of a substantial greenhouse and bricked foundations for a porch, wanted to congratulate the builder. Quite a feather in my cap.
I was very impressed you used the fine scale on the ruler when setting the marks for your foundations. I’ve seen so many builders setting things out with the 5mm increments.
By your standards, I’d be a bit slow, but can assure you, my projects are plumb and level.
Thanks again you are a true craftsman, CT
Thanks, Rodian, this is exactly what I have been searching for, the calculation of figuring out at what angle to cut each brick for my garden design layout. All you need to do now, to satisfy everyone's craving, is change the title of this video to "Voussoirs Calculations" or "Brick Arch Calculations".
Thanks again mate!! This was an extremely plain and simple way of achieving the end result of brick vault calculations.
The calculating in this video was top notch. Thanks for sharing .
i'll never need math miss, i'm gonna be a brick layer when i grow up.
You made templates. How did you cut your bricks? A jig?
That’s what I was wanting to see...
Nice videos!
me too, but judging that the cuts aren't perfect if you look close, I suspect that he used a hand held tool.
"the difference between a brick layer and a line layer" in Canadian brickie. Arches have always been my weakness as a brickie, love to lay on the line because I know i have the energy to do so. but not proficient enough to promise my work or guarantee a profit on custom work, a shame really but the modern north american brickie......Your vid separates the dollars from the cents. Love your videos thanks for everything you've posted.
Thanks for this - just used this method to do a curve on my patio - turned out great!
Loved this one rodian remember doin this wen i was in college
Hope you and your wife are doing well brother miss your bricklaying videos they were a lot of fun to watch
Absaloutly cracking video, thank you soo much for sharing your knowledge
These are videos I love. Keep these types coming!!!! Your awesome!!!
BLWP .. Bloody loved this video Rodian , superb 👌🏼. I’m ashamed to say I have never done any of this and was clueless how to. It’s difficult to get your head round but you explained it beautifully. Say hi to Boris for us too 🤪😂🧱👍🏼
Boris says hi 😂😂 I've used it a fair amount over they years, definitely very handy to know. 🧱🤙🏼
Rodian Builds 💪🏽👌🏼👍🏼🧱
Nice vid mate. Handy tip for equation to save all the fuss is pi × diameter gives circumference length, then dvide answer by 2, gives half your circle. Or just pi x by radius. in school i was shown your way but in college my bricklaying instructer showed me these 2 ways for semi circle so simple👍 for other arches with skewback its pi x die ÷ 360 × by angle at striking point. 👍
Like to add when dividing your brick devide it by 75 first if it gives 21. whatever then round up to 22 divide ur semi length by 22 will give you 73.5 more accurate + youll need extra joint beside key brick because our first sum gives us only brick + joint so 22 joints but arch has 23 joint so .5 taken from some bricks will give you it, there's another way but more maths to explain sub dividing remainders after decimal point. Youll find this way bricks will find a more true place in arch and allow you to build tight joint arches but the best way is traversing arch template after youve done this and achieve gauged arches with 1mm joint to the mm. By the way good to see some1 approach it the right way 👍
Mate do this all the time wish some body explained it to me this straightforward all the best
Legend. Bet most brickies can’t do it like that 👍🏻
Would have been good if you had shown just how you cut those little slivers off the bricks but otherwise excellent.
I'll make sure I film the cutting next time 🤙🏼🧱
Ahhhh😂😂that’s what I need to know! X
บุคคลผู้มากมีความรู้เป็นที่เชิดชูในหมู่งาน หมู่ชนชมผลงานมอบรางวัลอันชื่นชม..
This is brilliant. I'd love to see the same kind of video for working the cuts out for a Georgian flat arch.
I'll add that to the list of future videos 🤙🏼🧱
Any chance of a video on how to cut the Voussoir bricks? I need to know for a job I’m doing . Great videos
Great video be interested to see you do some tumbled in brickwork never done it myself wanted to get aload of bricks before lockdown so can do it in garage
Helllo great video to watch. Bit confused 1618.13 divided by 75 or 73? Is giving the amount of bricks that fit in the extrados? Cheers
Worth doing a bricklayers pilgrimage to brunelleschi's dome... you can get up inside the brickwork, really is worth it, the bricklayers amazed themselves when they built it...
Brilliant sir, fantastic video 💪💪👍👍👍👍👍
Great job, love the video's, just like hanging out with you for the day. It's not as easy as it looks, at least at first.
Never heard that term before! Great stuff
Great tutorial, It helped be out tremendously. Thank you
the title is off a bit but the knowledge is priceless thank you.
Brickslaidwagespaid xcellent vid as usual easily explained as usual keep them coming
Thanks for the info. I've done a few arches over the years but always most of the time I guess and cut with trail and error until I get it. Good info to know 👍
You so good at geometry you should change your name to radian 👍
Why don't you do what other's do spread the bricks out and fill the joints with morter!!! Only joking lol.... what a brilliant video. I enjoyed the learning experience, watching how it should be done
How do you cut the brick? Wet saw?
Great video. Thank you very much .
Does this formula work only on semi circular arches,,,how would you work out a c centered or a segmetal,,,
Great video, instead of using the equation of working out the courses around the extrados couldn’t you just dry bond the bricks around the extrados closing or opening the joints until it worked bricks, then mark on the plywood ??
Fantastic explanation and video.
Thanks. you helped a lot!
Good day!
I get lost at the final step in the calculation. When you have got the lenght of the extrodos arch you divide it by 73 so you can get as close as possible to 22 because you want 22 courses.
My question is how did you come to the conclusion that it should be 22 courses? I've watched the video a few times now and that's the only part i quite don't get
Cheers from Sweden 🍻
This is nice you put out the math. Can you do a video that shows the math to lay bricks into a perfect (close to perfect) sphere without using a trammel tool?
S
You have some brilliant videos Rodian, one point it might be quicker to dry bond around the extrados, mark each brick and line through to striking point. It saves that maths equation. Keep up with the videos mate
Nice set if videos you have mate; I have a lot of admiration and respect for the trade. Question, how do you cut the brick? Gas powered cutoff saw? Watching all the way over in Boston MA. PS Do you have any chimney videos? Particularly how to replace flashing? Not sure if that is in line with the general theme of your videos but figured I would ask.
Having slightly tighter joints (over the standard 10mm) on a axed arch is always a good look
You don't put your level to the centre, you mark the joint at the centre i.e if. 10mm joint 5mm either side and then put your level to the appropriate side, therefore having a parallel joint line to the centre. Otherwise the joints will be slightly tapered.
Great video. The zero in the bracket is the symbol theta. Theta is used to denote the angle in trigonometry.
I didnt know that, wasn't very good at maths in school. Learn something new every day 😁🤙🏼🧱
The title of this video should have been "Calculating the number and dimensions of bricks for an arch". I watched the whole video expecting to see how you cut the bricks so accurately, because that's what the title led me to believe you were going to demonstrate.
great video! thanks, nicely explained.
Amazing and thx for sharing. Echo other sentiments - how did you CUT them?
Thanks for this informative video, but what was the tool that you used to cut the bricks so perfectly?
Brilliant!
Great video mate, very informative
เมื่อฉันลงแข่งขันงานฝีมือที่ฝึกปรือมาแสนนาน ทุกคนในวงการล้วนขยาดและหวาดกลัว..สิงห์ที่ซ่อนเล็บทำเขาเจ็บถูกเย้ยหยัน ตัวเต็งที่ฤๅกัน เป็นสมันเมื่อเจอเรา..
Things must have changed always an odd number of bricks in an arch or you got a straight joint at the top 🤔
What’s the tool you’re using to make the semi circle line, the two compass points and pencil holder?
Can you put a link to the angle finder please...thanks Rodian, keep up the good (and very handy) vid's.
Cancel that, I just found it..."DAAAH!"
جيد جدا شكرا
Great video
Very useful video mate 👍
Very helpful but I would have loved to see you actually cutting one. Stationary saw, not grinder, right?
Hi I think your tutorials are a one 👌I'm looking to build an arch but I'm unable to work out the angle any tips is there a formula I could use there is no one on UA-cam and the ones on here are in Pakistani
nice video Rodes
Mate its such a pleasure watching it done properly, slap and dash don't want to know these days, hence city trained in 6 weeks. Keep up the good work thanks, Are you city and guilds or nvm trained?
I got my apprenticeship through CITB if memory serves me 😁👍🏻
No words needed 🥰🥰
Nice
That's not zero that is called "theta" used for unknown angle to be measured. But appreciate your help work so much. It's so helpful 😊
Briliant video... Well done m8
great work dude
Nice video :) btw it's greek Theta "θ" not zero.
Nice video's but at this one I'm missing the actual cutting.....how to do that??
I will do a video about this in the future for sure
@@RodianBuilds I see you never made that video
"and without moving that"
proceeds to move it the very next second
OR your radius of 515 mm x2 = a diameter 1030 mm x 3.142 = 3.236.26 divided by 2 = 1.618.13 , and its not a voussoir arch it's an axed arch as the joint's are wedge shaped , you are correct on finding the angle first on any given arch .
Hi rodrian,where would l get the trammel from,looks a good bit of kit
Could we build a brick dome with this methot
Can you tell which rounder you're using or where I can purchase that?
I learned in Canada to build arches in trade school we did wulith out math trial and earer with cumpas but find , Difrent methods but outcome same
Just a thought. Have you thought of doing these on perspex? That way you can draw them on the perspex, cut it out, have a semi-permanent template.
Oh, may o also ask, where does the 74, 73, come from in the equation or did I miss a measurement lol
Hi how do you cut the voussoirs?
Hi Rodian would you do a video on tumbling in brickwork please?
I'm sure I'll be able to do that, I'll add it to the future video list 🤙🏼🧱
A simpler way of finding the extrados for a semi-circular arch is to find to work out the circumference and simply half it, so Pi*Diameter/2
Great
Where can you get the big compass thing he uses
Love your videos man!! Just a quick question, so if I was to build a segmental arch, how do I find the correct angle to divide by as it wouldn’t be semi circular? (180) Cheers!
Go round with a pair of dividers.
Have you got a link for a large trammel to buy ?
Absolutely great video but you don't show the one thing your title claims😂😂
You could grind that joint down by 2mm and keep the heads at 65mm and looking normal. A cut arch is not normally made from standard bricks and 8mm joints look better than 10mm. Looked good though.
When cutting the bricks I did keep the head at 65mm and made the joint a bit tighter. I agree that an 8mm joint looks much better, especially in an arch 🤙🏼🧱
Dig the vids man!!
Anyone know where you can get a decent bricklaying trammel like that? Been on Amazon & numerous tool shops with no luck. Not on the hand tool list either.
Google trammel head set, you see them everywhere.
@thequion Thankyou.
Love your video but it would work better for me if you spoke slower and did not interject other info when explaining the math. I think you could be more graphic. Also it would be very helpful if you could run the method on arches less than 180 degrees. Thx I hope this is helpful. It would be for me I know. The important part is the math and layout I think.
Hmm - great but what was missed - oh - how did you cut them...
Great video, got a quick question do you think you need to go college to be a bricklayer? Can you teach yourself? Cheers
Lots have not been to college. Most of what's taught now you will never use. Multiple bonds and working arches are rare. I firmly believe you need someone to show you but for stretcher runs you do not. That said, college was fun and its always better to know than to chance.
Like 140rware said, a lot of people are laying and never went to college. I would say at a professional level you need to at least be working in the industry and learn on site and college helped me a lot. I dont think you could teach yourself and become a professional. You need to learn from more experienced bricklayers....in my opinion 🤙🏼🧱
Didn’t get a notification from UA-cam for your last three videos so I’m commenting in the hope you can make some money off these tight bastards 👍
👍
There is no need for trail and error for working out the vousoir sizes.just minus the total lengths of all joints from the extrados and divided it by the number of courses for the exact measurement. Your vousoir sizes are for an arc length 10mm less as the last brick doesn't have a joint added. Plus semicircular arches should always have an odd number of courses.
