I’ve got an Oak the needs to come down.

It has a good straight trunk for around twenty feet and its around 30-36″ at the base. Rather than burn it, I’d like to get it milled into some big square posts.

It might take a bit of handling but I could get it onto the trailer and take it to the sawmill, or is there some sort of portable mill that can come to the tree?

Does anyone have any idea of typical costs for milling/planking a tree?

Sounds as if you need something like an alaskan saw mill though finding someone near you with one would be easier as you would need a much bigger bar (expensive) coupled with a ripping chain. Arbtalk have a milling sub forum try there. Big J posts frequently and is from near Edinburgh, may not be close to you though.

Cheers, I’ll post this over on Arbtalk.
