Here’s the challenge with “free” lumber. What the owner really wants is someone to clean their property for free. This can be real hard work.
Mesquite trees are notoriously ornery.
They have thorns and they do NOT like to be cut or messed with. They are often very difficult to cut down. You can doze them, you can winch them, or you can cut them, but they don’t usually come easily. Having said that, @jeffbob is an expert and has all of the equipment to do it right, including some big chainsaws. He has cut hundreds of mesquite trees and has made a few dollars doing it.
I would consult with him on the viability of the offer.
A couple of things about mesquite. 1) if it isn’t cracked it isn’t mesquite. It is very difficult to find a large piece of mesquite, especially one with few cracks. The cracks are actually prized because they can be filled with epoxy and they look beautiful when done that way. 2) it almost never expands or shrinks even after cut so it doesn’t have to be air dried very long. The trees can grow under extremely difficult situations and I guess that’s why they don’t need a lot of water. 3) It makes absolutely beautiful tables, cutting boards and bowls. It is a hard and durable wood. Some of the most beautiful native wood turnings I’ve seen were made of mesquite 4) worst case, even the small branches make awesome smoked bbq.
Lastly, I’ve seen some very large pieces come into Rockler when I worked there. Three foot plus in diameter slabs. They always sell for a premium and they always go quickly. It is a very desirable wood.
@jeffbob has given me some and I love turning it.
