Okay, so I need to replace an old door knob for my mom.
I guess she had tried to do it and wound up losing all packaging and the installation instructions, so I have no template for how much larger the hole needs to be.
I have a drill attachment set and a cordless drill, but that's all (see pics). I've read about a bunch of fancy tools that are made specifically to do what I need done, but I can't afford to buy anything.
As for a template, I used fingernail polish on the part of the new knob that doesn't fit into the existing hole. I couldn't think of another way to get a somewhat accurate outline of the hole.
Also, I can't take the door off of the frame, it has to stay on the hinges.
I'm usually pretty good about figuring this sort of thing out, but I'm stumped. I can technically install the knob & it'll lock & work okay, but it ends up scraping against the wood and it comes loose very quickly.
About the only thing I can come up with is using the sander bits & going at it that way..
Any help is greatly appreciated!
