i ain't doing nothing wrong. when you are opening old holes or get a hole full of slush that then takes on water once you break through, things catch and that drill has got enough torque to wreck shit. see the above post by someone else. i will say this... once the ice gets thick, i clear the slush at least a few times before breaking through and soaking the slush and it helps immensely. so, in the sense that i now do things a bit differently, i guess that maybe what i did before was "wrong".
