minimalist truss press

[PCustoms]

I am so confused . Is it this hard to build a shed? Well on garage journal we go the extra step.

It seems in this we are all in agreement that the truss plates aren't needed for such a simple build.


But...

Not needed nor beneficial, but sometimes we get ideas for projects in our heads.

I am sure the OP is moving forward with this, but also hope that there is some learning on a better way to do it next time

my god.

Just chop up whatever plywood scraps you have and pay the neighborhood kids to pound in 2000 ringed nails.

All you're gonna do with 1/4 inch plate and a bottle jack is waste a bunch of time, and screw up some good steel plates.

I have never built a roof, but your beams + dual-kingpost face-nailed to the chords + plywood gussets nailed to top-chords and the bottom chord looks plenty sturdy to me. Do you have two pieces of 3/4 plywood at each gusset, so that each truss has a total of eight pieces of plywood?

Would recommend Larry Hahn's The Very Efficient Carpenter and a copy of Modern Carpentry (older versions are cheap, mine is from 1969 and is the technology you'd want to duplicate for a shed)

Ceiling joists, ridge beam, rafters run down beside and tie into the ceiling joist, you'll see it. Admittedly though, the rafters would normally land on the wall - so there is that... But if you landed them on top of a clipped ceiling joist and used plywood plates, might be fine.

Larry's book will set you free. So many epiphany's in one book. I first bought and read it 33 years ago.

Yeah, each junction gets plywood on both sides.

I don't have any beams there, and no dual king posts. At the bottom of the pic you're just seeing two trusses side by side.

Mine actually ended up with six pieces of plywood, since the king post was so short I just went top to bottom with the ply.

Here's some more pics to better show.

Also, I omitted the plywood on the outside of the first and last truss because it would interfere with the outside sheathing. These ones are not structural in the least since they sit on top of wall.

I don't know size of those members but I would think the spans may be so short it could have just been rafters and rafter ties and skip the plates and king posts.

OP could do same with 8' roof. Rafter tie might have to be 2x6.

It doesn’t need to be 3/4 ply. 1/2” acx works very well

The biggest thing is the nails. It need to be LOTs of 6 ring shanks to keep from splitting the wool and spread the load evenly.

This truss I built took over 600 nails. I wish I had a nail gun that shot that size.

Many don’t put enough nails in and the ones they do use are too large.

600 nails? I'd buy a gun just for that project.

My Ridgid framer will run 2" 0.113's, which I believe is a 6D

After I was done with it I right arm wished I had bought a gun for it.

If I ever do it again you better believe I will buy one!

Also I belive they were 6d box nails(.098" diameter) on the print called out not 6d common nails.

 

[billconner]

Feels like a perfect application for clout nails.

Can’t just use nail plates and run ur truck over them?

I think you'll be at least an order of magnitude too low on pressure

Put a lot more air in the tire? Lol

Holy ****, that's a good idea. You should try a career in nuclear engineering. Wicked smart.

lol. Just here to help!

I found this instructional video from Simpson. Interesting that it shows a truss with a tie-plate that uses common nails, not a gang-nail connector plate.

Plates have to be pressed properly to work as designed.

Several people have said nails and glue. GLUE does not hold up over time and you will never see it on any drawing for truss connection. The only fastener on home built trusses is specific nails with the required sheer strength.

Yep. Plywood gussets and nails is normally how this is done for DIY trusses. Dad and I built a good sized pole barn - at least 30 x 40 - many years ago using state extension plans. Only 4 large trusses of 2 x 10s as I recall. Large 1/2" ply gussets on both sides with 8d nails on 2" centers all driven by hand. A ton of nails. It's still standing about 50 years later.

For a long overhang I think a vertical right over the wall would work. Then some diagonal braces going inward. For this size truss the strength needed isn't that difficult.

A photo from 1998 of a nailing party for the gambrel roof trusses for my dad's 64'x24' barn.. our kids helped for a bit, but we had a lot of trusses to nail. Ring shank nails, 1/2" plywood. We lofted the trusses on the raised floor. The lower section now has a slab floor.
