A regular modern hand drill uses either a trigger or a spring mechanism, meaning that you have to actively hold the button for it to speen, so if you drop it it stops instantly. You'd also be wise to remove the pointy bit and all.
See the clamps at the image? if you turn the neck of the drill you can open the clamps wide enough to grab anything that can fit in that orifice, you only need to figure a guetto mechanism with nuts and bolts attached to a locknut torque to hold the ona and that's it
They also have speeds so dont be a retard and both lube it well and dont put it on turbo
