Posts, glue-nail 2x45 or 1x90?

[magnusss]

I am going to build a fence and I wonder what to do with the posts.
What holds best, nailing and gluing 2x45 or should you buy 1x90

What dimensions should the finished post have? 45x90?

Outdoors, it usually turns out to be worthwhile with the massive posts, i.e., don't glue two beams together. Is it 95 x 95 you'll need to buy?

 

[magnusss]

Sponken: The finished should be 90x90
anaitis: Yes, it will then have to be 95x95

What dimension should the studs be?
I am going to build a 1.8m high fence with cover panel.
I was thinking of placing 3 horizontal nail studs but I'm a bit unsure about what dimension I should use, is 45x70 enough?
Or should it be 45x120?

What cc on the posts?

 

[magnusss]

Hmm, I think it was 1.4m between the posts. I'm considering having an overhead beam, so the posts might be 2.10 high.

 

[anaitis]

Then you can probably manage with 45x70!
Maybe even with something thinner.

You'll probably have to buy 95 x 95, right?

In what way? My own experience says the exact opposite, if you want to be sure to get warped, twisted posts, you should choose, for example, 95*95... Unless it's because you think it looks ugly: take two 45s instead...

 

[magnusss]

anaitis: Ok but if I want to be on the safe side, maybe 45x70 will be good?
bigsnucke: If I'm going to glue together two 45s, does it matter how the growth rings align?

 

[bigsnucke]

It certainly does, but if you ask 10 "byggnissar," I think you'll get 5 who are absolutely sure that the growth rings should face one way, and the other five would bet their lives that they should face the other way... (It's been hotly debated here on the forum which way deck boards should lay, without reaching a consensus everyone agrees on...) In other words, it's probably fine either way.

 

[magnusss]

Yes, you are so right=)

The core side outwards of course!

 

[mattiasp]

When looking at finished glulam posts in size 90*90, they are glued with the core side facing outwards. Like this: I))I((I

 

[magnusss]

Thank you, that's what I'll do.
What kind of glue should one use?
Regular wood glue for outdoor environments or perhaps standard PL400/600?
