Garmar, it's not just useless but it's HIGHLY DANGEROUS!!!!!!
If you try to turn it, cut it, burn it, throw it away, give it away, sell it, or dispose of it in any other way IT COULD DESTROY YOUR ENTIRE NEIGHBORHOOD, IF NOT YOUR TOWN AND STATE!!!!!
You have to get a professional involved OR TERRIBLE THINGS WILL HAPPEN!!!!
Now, I know it's not usual but I'm SO CONCERNED that I'd be willing to step in and help with this. I'm a certified S.C.A.M.M.E.R. (Specialized Cottonwood Accident and Misuse Mitagation Expert, Retired) but would be willing to take this on for a minimal fee, ney, FOR FREE, because I'm so concerned for your welfare.
Just have the burl expertly strapped to a pallet and ship it to me. I'll handle it from there.
And remember, DON'T TRY TO USE IT AND DON'T TRUST ANYONE WHO TELLS YOU IT'S SAFE!!! YOUR LIFE AND THE LIVES OF ALL YOUR LOVED ONES COULD BE AT STAKE!!!
Thanks,
Dietrich
