How to build Gambrel Trusses | Barn Style Rafters | Shed Build Part 3

- I built 9 barn style trusses for my 10x16 shed. This is a studio / workshop space that will have a loft. The Gambrel trusses provide plenty of headroom in the loft. I show detailed plans for how I built my trusses using 2x6 lumber and 1/2 inch plywood gussets.
A viewer has noted that a bottom rafter cut at 54 1/8 inches instead of 54 1/2 inches worked better for the 10x16 base. Please double check the measurements I'm suggesting to ensure your trusses fit your build.
*Disclaimer: I'm not a professional, just a seasoned DIYer. You should double check my measurements and advice and adhere to your local building codes.
Thank you so much for this video. Crazy we are so lucky to have stuff like this these days
I am learning from you. A few hints that may help others: If you make the cleats on your floor thicker than 1.5", then they will help line up the gussets perfectly, too, with less likelihood of getting something imperfect, and faster. If you have a reciprocating saw, put a deep blade on it and us that for the trimming of the 2x6 cuts at the ends. Make a template for the rafters from scrap plywood or OSB that's shorter than the rafters, so you can run the edge of your circular saw on the template, making every cut exactly the same with little chance of a mistake.
I am saving this for our shed build. Total MVP work. Great job
I'm from Brazil, tks soo much for vídeos... Thanks thanks thanks
When you are using a pattern, to replicate a measured piece, always use the same piece for your pattern. Never use the next cut piece to be your pattern for the next cut piece. If you don't your final piece could grow from the first to the last. Otherwise, very well done.
Agreed. If you are off by 1/32" on each cut, you can potentially off by a full inch over 32 cuts! Obviously that's the worst case scenario, assuming you are consistently making each cut heavy (or light), but it's very easy to be off by 1/4" over that many cuts. If you use your method, worst case, you'll be off by 1/32"
@@ryan370a big mitre saw sure is nice for this type of work since you can clamp 3 boards together and cut them all at once to exactly the same size. With a sliding mitre saw you can usually set the max depth and also make at least one of the birds mouth cuts across a whole bunch of boards at one time.
Im doing a 10x10 gamrel shed in my back yard, this has been helpful.
Thanks !
Thank you good sir for making it plain, simple, honest, direct and to the point. That is one thumbs up well earned. I sure wish I could email you a beer. Have a blessed day.
Great video, many thanks, this helped me tremendously.

One of the ways to make these trusses stronger is to leave a notch at each of the 3 peaks and tie them together with 3roof beams one at each peak point also attaching the loft floor trusses/1st floor rafters to the bottoms of the trusses
Thank you so much Have a blessed
What a stud! You make me want to be a more useful person. I love that you used the graphic in the beginning to talk about the style of the trusses.
Haha, thanks man!
@EveryotherKarl how do I measure out the seat cut for the truss? Please help!!
you're blowing up! can't wait to see the finished shed man, nice vid subbed
Dude super great content. Thanks for explaining everything. Great job
Great job! Really enjoying this series. I'm doing a gambrel 24×24 pole barn/shed with loft. This is the best tutorial on the trusses I've found. Sub'd!
👍 thanks for sharing!
Спасибо! Это очень полезно для меня!
You definitely explain the process well. Tone and calmness perfect.
Only issue is too much time on each step. Camera details great too.
If you put out more helpful videos, shorten detailed steps and lengthen process on each, I see many more people joining, such as myself.
New subscriber here! Looking good!
I want to do a 16x20 for the tractor 🚜 attachments and all the yard equipment.
Thank you for the video, it was really helpful! Any idea how to find dimensions/angles for an 8' span?
You set the seat for your trusses at 3.5 inches. This does not account for the wall sheathing. Won’t you have to notch out the sheathing first each truss ?
Yes I did have to do that.
I see the overhangs on your trusses fit very snug without the sheathing. So when you install the trusses and then hang the sheathing, it will come to the bottom of the overhangs. Would it be better to leave a gap in the overhangs and have the sheathing come up under it?
great video
could you go higher on those trusses for same sized shed? To give more room above?
Nicely done, but how did you arrive at the 48" and 54" rafter lengths? They would have to be different for wider or narrower structures, right? Did you get help from Pythagoras?
You're correct, they would be different lengths for wider or narrower structures. I went off of the recommended dimensions from a site called buildblueprints.com. I referred to their 10x16 barn shed plans. I figured I'd trust their math!
@@EveryotherKarllooked at that link, didnt see any Dutch barn roof plans?
Karl nice video and tutorial. I am planning to build a 12 by 16 similar to yours. Was planning on a lean to roof but considering the gambel style because of the loft idea. Was just curious did you cover your floor too when it rained?
Good luck with the build! Yes, covered the floor when it rained. That was pretty important.
Wow...cutting all your angles with a circular. You don't glamp, do you?
Hi, just wondering what the peak height of the shed was after walls were installed and roof was put on?
It's about 14 feet to the peak
At what angle is that notch? I get it’s 3.5 in and 6 down but at wat angle?
I'm building a 12' x 16' shead. What would be the length of the boards with a birdmouth of 4" overhang?
I don't want to give you the wrong info, I'd recommend using an online gambrel truss calculator.
I am planning on putting 4" facia and a barn red vinyl siding to protect the wood as much as I can. By the way, great video!
Do you have to take into account the width of the sheathing/siding when cutting the birds mouth? Or does the sheathing get cut to go around the rafters?
I personally cut the sheathing around the rafters, but you could do it either way.
@@EveryotherKarl ok thanks for the reply!
I personally build these adding the side walls into the equation
@@toomuch4199how would you measure the seat to account for the sheeting? I'm new to this
Why not make a 4' knee wall and a 12 pitch roof?
Does the 22.5 degree angle the same for a 12' wide roof or does it vary on your width
It's the same angle, the length of the rafters is what would change.
The angles should always be the same with longer rafters for wider buildings or shorter rafters for more narrow buildings. Good luck and have fun with your building!
Ok so my rafters assembled is like an inch off for a 10 foot wide floor flush to the birds mouth is that normal? Or is 54.5 not exact but an estimate length on the bottom piece? Something here is off or is it off to compensate sheathing?
Hmm, interesting. My bottom pieces were exactly 54.5 long. Are your top rafters 48 inches?
If anything maybe the birds mouth could be adjusted?
@@EveryotherKarl yeah the run and rise match’s all pieces measurements just like your tutorial describes. I mean it’s like 3/4 off a bit I could make them work when I attach them to 2x4 top plate.
I’ve reviewed Build Blue print you recommended and the rafter 67.5 degree is measured at 54 1/8 versus your half and when I applied this it fits perfectly to a 10x16 foundation.
@@TACOPOTENTE dang, ok.
@@TACOPOTENTESo you're saying to cut the bottom piece to 54 1/8? Also how do you measure out the seat cut?
If my shed is 11 wide and I want 6 feet of head room and 5 inch over hang could someone please help with my measurements
How the fuck do you calculate the angles for the 4 different beams?
I did one of the simplest methods which is to just make all the angles 22.5 degrees. You just need to calculate the length of each beam depending on how wide your building is.
hmmmm thanks for answering so quickly. I need to figure this shit out... @@EveryotherKarl
Might I just suggest a jigsaw don’t really like the fact of using a skill-saw for some of what you were doing
@@curtisruth7906 sure, you can definitely make more fine cuts with a jig saw. Skill-saw helps make everything faster usually.
What’s the length of each rafter?
The top pitch rafters are 48in, the lower pitch rafters are 54.5in.
Great I’m about to start this process myself I have everything to this point completed.
@@EveryotherKarl Ran into a snag my Speed Sq doesn’t have a quick 22.5 ref line is it 4 of 12 ? For those who don’t have a quick angle 📐
@@TACOPOTENTE Hmm, if you don't have the 22.5 mark, you probably at least have 45 and/or 90. You can either bisect 45 or divide the 90 into 4. That'll be the 22.5.
@@TACOPOTENTE if you have a miter saw, that should have the angle you need on it.
