Hi All
A quick question, hopefully someone knows the answer.
I was talking with my carpenter friend the other day.
We got to talking about Roof Trusses.
He said that he was told by an engineer that the nailed on plates
that hold the trusses together had extra holes for nails.
And that after the trusses were installed, he should nail the plates
with these holes.
The engineer said the trusses were shipped without the extra nails
and that they were to be nailed after instalation.
Anyone know anything about this?
Jeff

I've been in the truss business for 18 years, and have never heard of anything like that.
Either your friend is confused (Or misunderstood the engineer) or the engineer is full of it.

I'll talk to him again and see what I can learn.

You can some up my understanding of trusses in a few sentences, but I do know they do not come with "some assembly required"Never be afraid to try something new. Remember, amateurs built the ark, Professional build the Titanic.
Jeff, I got to thinking about this thread last night, and there is one thing I've seen done that might have confused your friend.
A couple of times when truss plates were mistakenly undersized by plant people who assembled them, they required some modification. If there was enough steel on the joints but not enough teeth, I've seen an engineer call out 10D X1.5" nails driven into the plate slots to strengthen a joint.
That's pretty rare. But if your friend happened to be involved in something like that once, he might assume it was normal.We can do no great things, only small things with great love. [Mother Theresa]

I've been away for a few days and just started catching up.
I haven't had a chance to follow up on the thread, but when I do have
a chance to talk to my friend, I'll let you know what he said.

didn't they both sink?
"but I do know they do not come with "some assembly required""
That is not true. Some do need assembly because they are too big to ship otherwise.
shows just how much I know, Guess I should have said, I have never had a residential truss arrive that needed to be assembledNever be afraid to try something new. Remember, amateurs built the ark, Professional build the Titanic.
Than you need to start working on some of the grander McMansions going up in my area....that's not a mistake, it's rustic
Yo college boy -
I think what they're referring to are "piggyback trusses".
Truss plants are limited in how big of a truss they can build and ship. Some can build up to 14' tall, and others only around 12 or 13'. Depends on the equipment they have.
Basically what's done is that they make a flat top on the truss, and build a "cap truss" that sits on top.

Yo Truss Guy,
Thanks for now doubling my knowledge on trusses :)
