So I'm just getting started on basic home improvement type tasks, as I am now in a situation where I'm permitted to actually drill holes and stuff ;) I've got a bicycle rack that is supposed to be screwed to the wall, and then you hang the bikes on it. I'm trying to set it up in my garage. The garage wall looks like its made out of stacked cinder blocks or something, so I pulled out my drill and set about making a hole.
The following points concern me:
1- According to the rack's documentation, it is designed to work when mounted into a wooden stud. According to my stud-finder, the entire wall is a stud, so I think I ought to be ok? The rack says it won't work with metal studs, but I don't know how I would know the difference.
2- When I drill into the wall, The 3/4 inch or so goes real easy. Then the sound that the drill bit makes in the wall changes and progress comes to a complete halt. I could keep trying to drill, but I'm worried that I might be drilling into something that maybe I shouldn't be? Do walls normally vary in difficulty by depth when drilling, or is that a red flag?
