Elm Burrs

[OldWood]

I put an query in the General forum asking about processing burrs and didn't get any answers - let's see if anyone here can help.

I found a fallen elm tree while out walking, partially logged to get it out of the way. It is covered in burrs. Before I even consider pursuing who owns the land, etc. how can I check the burrs are worth harvesting? I have retrieved a log with some burring on it. What do I aim at in cutting them off with the chain saw - ie how deep into the 'trunk' wood should I go?

Unfortunately there is no simple answer other than cut and see. I have had elm where the burr has gone several inches into the trunk and on the same tree a large burr that didn't show 2" into the trunk.

For cutting them I would go at least about 4" to 6" if possible as this gives a nice depth if intended for turning. Also don't try and cut around the burr in a circle instead cut a large square out around it as this makes it easier to handle and store.

A bit like this.

Of course this is just my way of doing it others I am sure will have other ways. I will be up in Edinburgh in a few weeks if you want a hand.

so we're second best eh!??!!??!!? :lol:

there's no way of telling how deep the burrs go- the burr figuring could be just in the carbuncle type lump or it could go right down to the pith- such is the joy of buying burr wood.

when i buy burr wood i'm liucky enough to be able to dock the ends with the seller present and check what the fiqureing like-but it could be great on the end of the log and 18" away it could be gone- there really is no sure way of telling until its been cut up properley.

One point in relation to burr that may get used for turning or making display pieces is to avoid leaving straight edge cuts too close to the burr area.
Many a spectacular Burr piece is spoilt because they present a cut flat as opposed to a natural irregular edge when worked.

Well at least I got some good answers here !! Thanks guys. I take it you don't do *general woodworking* then.

It's chucking it down with snow here and I'm skulking in doors doing other things. When it does get a fraction pleasanter I need to sharpen the chain saw and then follow your guidance. The one thing that does worry me is if the burrs have rotted as the tree had obviously been there for some time.
