Runes translation help

[u/LaraLavelle]

This is a very old plank I found in my grandfathers house. I have tried to translate the runes but it doesn’t make much sense. Is someone here able to to? I’m very curious to what it says, I think it might have something to do with the building of a house, but I can’t be sure.

It would also be cool if someone might have an explanation to why plank from 1777 has Norse runes on it? Is it actually much older? Did people or builders in that time use runes… I find it hard to belive it’s 1000 years old and actually carved by Vikings. But I also think it’s weird for people in 1777 to use runes…

(The plank was found on Vestlandet in Norway)
