Building gambrel roof truss

Hey, welcome back to Garden Spot Acres. This is Chuck here, we’re going to be working on our trusses today for the goat barn. So what we’re gonna be doing is taking our two by fours here and cutting them down to the proper length with the proper angles on the ends. Let’s go ahead and take a look at what we need for our lengths. Let’s see what we need here. We need 5:4 and 9/32s Now that’s approximately five feet four and a quarter to five feet four and a quarter and a little bit longer than as 9/32, so five feet four and a quarter, and I need to cut 22 and a half-degree angles on the ends here.

In here right, so I’m gonna go ahead and take my two by fours I’ll, be using eight footers that’ll leave me some remainder that’ll be used for our sailors on the front and back walls of the goat barn. So let me just go ahead and take those four two by fours and cut a 22 and a half degree angle on one end of them. So we have a positive stop here at 22 and a half degrees.

I’m gonna set that – and I don’t want to waste anything so I’m going to bring that right here to the point and cut that little tip-off. Okay, I’ll do that on the other three, and I’ll, be right back with you! Now we’re going to flip our lumber around here turn our angle to 22 and 1/2 degrees, the other direction, and I need five feet. Four and a quarter heavy got a nice shadow line there. Let’s double-check that link.

Every roof truss consists of 4 pieces

Okay, good, lay this one on top mark It like that and put an up on this for a pattern, and we just keep using that all the way through I got to cut forty-four of these out total I’m gonna make you 11 trusses. Each truss takes four pieces, so I can just break that. Put that off to the side here and go ahead and cut that angle. Like that, all right, I got our four pieces cut. Let’s take a walkout to the goat barn, where I have the floor already done, and let’s go ahead and see how we’re gonna put these together.

Okay, we’re up to the goat barn. I’ve already started setting my trust jig up here on the floor. That’s why you want to do the floor and you want to do the trusses right after it. You don’t want to be building your walls. The trusses would come after the floors built. So you have the big open area to build your roof trusses plus. You can use the corners of your barn to make sure your trusses line up at the 14 feet, which my barn is right.

How I set the jig up

So what I’ve done here, Let me just run through how I set my jig up so far. My trusses need to be 14 feet from the outside tip over there. So all I did was take someone to buy lumber, screwed it to my floor and did the same thing over on that side and it’s exactly 14 feet from that point to the same point on the other side over there right then, I went to my sketch up And my sketch up says it’s six feet: eight in 7/32 to the peak from the center of my roof truss, which is exactly 7 feet. So what I did? I marked off 7 feet from that corner over to here. I marked off 7 feet from here over to there drew a line and you can see it down here and right.

There is the mark, I need where these trusses have to come together right at the base here. So that was the second thing I did. I put the corners on first over there, I found the exact center of the width of my trusses, which is, in this case, is exactly 7 feet because my building is 14 feet wide. I marked up from the bottom of the base of the truss to my exact point which Sketchup says is 6 feet: 8 in 7/32. That’s right there!

Now I have that measurement. So I know they need to come together there. The only other measurement I need from the sketch up is the distance from that point to here. Perpendicular to that point there so Sketchup says it is four feet eleven and thirteen thirty seconds. So I measured from here to there to put on a t-square, drew this line then from here right here to here. It needed to be two feet and nineteen thirty seconds of an inch. So I did that, so the first thing we did put our corners to find.

The exact center of our width of our building seven feet took a long t-square mark it out up here. Measured the distance that Sketchup says it’s from the base. To that point up there put a mark – then I measured from here to here and along this line. Perpendicular to the side wall along that line, I measured the distance that Sketchup told me that this point is and that’s all there is to it. Then I got them all situated and then I started to put my jig together. I put this in here.

I got it all laid out perfectly put my knee on here like this put this part of the jig here with this part of the jig here. So now, look at what happens every time. I get a new piece, a new trust. I want to build. I just pop it in there to pop it in there to make sure it’s tight. Its exactly the same point, and I can do the same thing here to pop that one and put it up against this one. This one can’t move. So that’s exactly where that one needs to go so I’m going to go ahead on the other side. Now put my other jig pieces in the same places.

I put these in basically and then jig will be set up. Let’s say we got tight here. I got to be right here on that mark right there, so I’m gonna set my jig up. Take some screws. I just happen to have some of these pre-drilled hey, make sure she’s seated in there well come down here and pop one in here now that one’s in place the last one I have to do is this piece here and that should fit tight right there pop her into place, put her down look at that to make sure she’s still good up here there we go so I need 11 trusses.

That’s 44 pieces. All the same, I need to do the double plates on all the roof trusses, except for the end walls. They only get a. They only get the plate on the insides. So the next step I have to go to my plywood and have to cut my plates out for these angles here. So each gain each truss gets a plate on each side.

Use table saw or a paneling cutter the trusses

3 on this side, 3 on the other side, except for the animals. Alright, I’m ready to cut my plates out or my gussets, whatever you want to call them, I’m gonna make them all 24 inches long 9. Inches wide. Wish I had a table saw big enough to cut this or a paneling cutter, but I don’t so I’m up here on my knees, cutting this on the ground. This is one of the earliest Rio because they made 18-volt saws. I think I picked that up in 90 – maybe 95 – maybe even earlier than that, but with these new lithium batteries, bayonet breathe some life into those saws.

Okay, we have our 9 inch by 24 inch gussets I’ll place them on here. I’m using one two three quarter inch screws that one’s done, I’m gonna do now is an eyeball. This draws me a line eyeball. This way draw me a line. Lets set this for half an inch, approximately all right, the moment of truth pop these out of the jig and there we go so now I’ll do the same thing. On the other side, okay, we have our 9 interior trusses all built, I’m on to my gable trusses. Now, one’s gonna be a solid wall gable end, so I don’t have to frame up any door or window in it. So what I’m going here is just taking a 12 foot 2×4, I’m coming up 24 inches from the top plate of where the wall would be up to here. This here is just an end of one of my cut-offs for my trust, rafter pieces. It’s the same 22 and 1/2 degree angle that I’d have to cut on here. So I just again I measure 24 inches to see the mark. There.

I’m just gonna put this on the top eyeball that draws that line comes over to this side. Do the same thing, and I know I just have to cut those off and place that in with a gusset like I did with these didi dadi, you do. Okay, I’m gonna use these cut-offs that I cut off from my gussets here. I’m gonna use those over here twenty-five and a quarter twenty-five and a quarter, and look at that. I can use these gussets to hold that one in place. This is actually for my back wall. It’S gonna be solid. That’s gonna be that side over here facing that way. All right, I’m gonna lay out my last able truss I’ll come back to you as soon as I get that one built, then I will work on the framing part of that because we do have a four-foot-wide door going into this one to access The loft okay, here’s the mark for my upright

I have this piece just placed in here, so I have a guide for my tape measure its square to the base, I’m just going to measure up until I hit the rafter truss up here and measure down. I need 60, 1 and 3/8 to this point here. On the long end, 61 and 3/8 and I’ll cut it exactly the same over here, So I need a 12-footer to get both of these out of it. Okay, there’s that one! Let me get the next one: Good overlay, a two wife hey now, I’m gonna come across my cross piece up here.

Let’s go ahead and see what it is: forty-eight three eights last thing I need to do with this gable. Trust here is to put a nail in here and one on the other side. Okay, we’re finishing up our cross pieces here. These are just failed, so I already got those down here, blocked in with two by fours. I’m gonna do this and with the plywood all right, there’s the gable end with our door, opening in it

The final framing

We start just with the regular truss. We put this cross-piece in here. We put our uprights in. I got them spaced in the center approximately four feet. Apart put our top cross-piece in up there put a couple of nails in on each side. That’s my truss! All framed off for the gable end with the opening in it thanks for coming along today and watching our trust-building our next video we’re gonna start, the wall, framing I’m gonna, be doing the long walls. First, they’re gonna be framed upon a two by sixes they’re gonna be about six feet: four and a half inches tall to the top plate.
