What did I do wrong with the tongue and groove?

[Snailman]

biltema has coiled nails 65x2.8 hot-dip galvanized = holds well, you can loosen them and nail them by hand...

it should fit the 45 stud

but I would probably also have used my nail gun...

Isn't it true that nail guns break the wood, I've seen frightening examples of this and honestly, does it really make it faster when installing 17 mm paneling indoors?

 

[Snailman]

Yeah, I was mostly thinking about tongue and groove boards for the rafters, for the exterior paneling I nailed without a gun (with 50mm collated nails (panel 22 mm, battens 28mm = 50mm), went through a few boxes, at least 5 or so...):O

But seriously, where should one buy lumber?
I'm starting to get tired of Beijer.

Is Optimera better?

 

[Elkludde]

Do not know lumber dealers in your area, but I have bought from Byggmax and another local dealer.
22 mm that were placed on the attic's roof beams, just fastened them with a few screws, they have dried together but not warped.

The driving depth is adjustable on most quality machines. Then if you have a poor compressor, the pressure will vary and you'll get different driving depths depending on how long it has been since it pumped up the pressure.
Ideally, you should have an 8-10 bar compressor with a regulator, then you can maintain even pressure.
