While I wanted to start hacking off the Chevy Nova’s crumpled old roof off right away, my dad patiently informed me that first we needed to spend some time drilling holes in concrete. This step is necessary so we can install anchors into the ground that will allow us to pull the car back into shape.
Planning the Placement
We began by planning where the holes were going to go. And by “we” I mean that I sat around watching my dad pensively pondering the placement of the holes.
Drilling Holes in Concrete
We rented this gigantic drill, called a core drill, that cuts the most perfect, beautiful holes in the exact size you need. For our purposes, we used a 3 ½ inch bit to make our holes.
Drilling holes in concrete is way more fun than drilling regular holes because we literally cut giant, cylindrical chunks from the floor! It works very quickly once everything is set up properly. The drill sits securely on the ground because of its vacuum base, which creates a super strong suction. We didn’t have to worry about it budging even a little bit while drilling. The garden hose attaches to the drill to keep the bit lubricated and cool. When powered on, it spins like a normal drill. My dad carefully controlled the drill as it bored through the concrete ground. Once it broke through the bottom of the floor, he raised the drill and we were left with perfection:
We drilled a total of four holes. Next, we will install the anchors into the holes and the body work can begin!
I have to figure out something cool to do with the perfect concrete cylinders that were created in this project! Any ideas?
