For most this will just be useless information.
But...... several people have asked so, this is how we cut up a bigger burl into slabs.
These photos show one of the guys here cutting up a big maple stump burl into slabs.
The burl had been a decorative piece here on the grounds for several years. This gave the burl plenty of time to season and develop some good coloring along with a bit of spalting. In the first photo Josh is trimming off trunk pieces to make the piece easier to handle.
With the pressure washer he is blasting out dirt and rocks from the hollow inner portion of the burl.
Now it is pretty clean and ready to start cutting.
The burl is placed on a cutting table where he starts cutting using a pole mill. This sort of setup holds a chainsaw with a 5 foot bar parallel to the tabletop so slabs can be cut accurately.
First cut takes off a portion of the outer surface of the burl so we can see what is inside.
Now the first slab.
A few more slabs.
Now we are getting to the portion of the burl that I will be taking to cut up into blocks.
This part in closer to the inner hollow portion and has good color and burl figure.
He cut through a rock so it is time to resharpen the chainsaw before finishing cutting up the burl.
