I have an old cedar tree w/ 2 trunks. They're splitting further apart, so I searched and the recommend approach is to drill a hole thru the trunks, run a threaded dowel rod thru the hole, and then tighten nuts on each end to pull the trunks together.
The problem is that the wood boring bit and the drill bit extender are stuck in 1 of the trunks. The bit spins freely, but it won't cut in any deeper if I push on it, and I can't pull it back out even w/ a vice grip. I just can't think of a scenario that would cause this. I know there is a hollow area inside the trunk, so that may have something to do w/ it.
I've tried drilling some other holes in the area, but I can't get in deep enough (there isn't much room between the tree trunks, so I can't hit the angle I want).
Below is a pic similar to what is stuck in the tree. I already drilled a hole all the way thru both trunks w/ this setup, so I know it works.
