Yes, it's worth saving, however, as you said, the cherry burls are prone to ant colonies and such. It's kinda touch and go. I've had several cherry burls . I found most of them have holes on the inside from the creepy critters. when you cut it up, i hope you find the darker colored burl. Some are a bit on the salmon color side but the dark ones are beautiful , in my opinion. Also when you stabilize them, they will darken up a bit. I think cherry burls don't get enough recognition.
Here is a little story:I found a cherry burl at a flee market. It was huge. It had a bunch of tress that were cut down next to it. I spoke with the owner and he said he was going to cut that cherry and a bunch more trees for a parking area. He cut the tree down and used a dozer to put the burl in my truck. The tree was small but the burl was huge. It looks like a snowman body with the bottom part of the burl being larger than the top. It takes two people just to move it- not to lift it. It probably weighs 350+++lbs. I sealed it up to kill the bugs and its been drying for about 3 years. I'm hoping to get some nice shelves or maybe a small table. I forget the dimensions but I know it's stands up to the chest and is my wider than me. Im 6 ft 210lbs- to give you an idea.I'm hoping to have minimal damage on the inside. I will most likely cut it up into slabs and let dry some more. Take care- good luck. Burls are always worth it, if not for the fun only.-Marekz
