Then pipe and a funnel to get the stuff down in the holes.

That’s cool I didn’t know such a thing existed. But that poses another problem 
how do I get it into the rock that I want to demolish that is 7 feet down in an

We are setting 60’ utility poles for customers and bought our own auger truck 
and core barrel to do the work. It all has been going well up until yesterday. 
We don’t have use The core barrel very often. Most of the time the core comes 
out after you get it cut. However yesterday, we cored down to the depth we 
needed but the rock core did not break off to pull it out of the hole. Has 
anyone out there had any experience with something like this what is the next 
step to get the core to break out? Normally we wiggle the barrel around a 
little bit and the core comes right out. In this case it will not break loose.
