"O.k. so the next thing that we need to do to replace the doorknob. In this situation, is the hole is a little bit too small. So here I have a file that is a rasp actually which is made for filing wood. Now I also have a handle. How this handle work is you simply twist this part and this little clamp opens up and you can fit this in the tong of your file down in to here. And just push it in there as far as you can and then start tightening up on the handle and this clamp, this clamp will squeeze together and then you tighten up. It's not, it's not perfect but something like that and it holds it in there and then you'll note that the file only cuts in one direction. So you just want to follow that direction. If you drag it backwards you will clog your file. So this is a rasp made for filing on the wood. Since our door bolts are wider than the door hole we need to use a wood rasp to widen the hole just in this one area. O.k. so I'm going to go ahead and take our rasp with the curve side and I'm going to move material inside of the door."
