How to Make Door Knob Hole Smaller


Most people like to make their own house by their own hands and think about everything themselves. However, when it comes to the doorknob, everyone will feel very hard to choose the right one because there are many types of knobs on the market. It may be easy for some experienced people, but for newbies, it is more complicated. If you need a small hole for your house decorating or installing this item, you should know how much time you need to drill through the wood or wallboard without hurting it. Today I am going to discuss how to make door knob hole smaller.

Step-wise Guide on How to Make Door Knob Hole Smaller

The following steps are showing step-by-step instructions on how to accomplish this task with less effort and carelessness.

Step 1:

To get rid of dust from wood first, damp the surface with water or any other cloth to wet down and wipe off the dust.

Step 2:

The easiest way is to drill a hole in which you will install your knob. If you want the bigger hole, then, of course, you need to drill through more than one time, but it will take a longer time than just drilling once (it is acceptable if you need to drill through a second time).

Step 3:

After finishing this step, switch on your drill and leave it by keeping its tip on the knob’s hub. Although this step doesn’t do much harm, I recommend not damage the surrounding area while rotating. Just turn it in for five minutes when leaving the tool alone. If your knob is that tight, it means the hub can be damaged. After a few minutes, try to rotate the knob manually in both directions and see if it works better. If not, don’t remove the nut. Instead, add some more grease to prevent rusting.

Step 4:

Now, let’s go back to our project. The hole you drill is not in the center of the doorknobs hub, so keep your focus online and hit it many times. It will be better if you can measure the distance between holes and do your work properly. You might need to use a hammer. Now, let’s go back to our project.

If there are any scratches on the polished surface, don’t worry because they can be fixed with sandpaper or other tools. To make the doorknob hole smaller, use the sandpaper or other tools to remove all the dust from the surface.

Precautions While Making Door Knob Hole Smaller

  • Remember to wear safety goggles while you work. You never know when a tiny wood chip might decide to go in your eye. 
  • If the hinge pins are bent, remove them, and use needle-nose pliers or a wire brush to bend them back into place before rehanging the door onto its hinges.
  • Don’t let small children run amok with hammers and screwdrivers while you’re working on the knob hole, either…accidents do happen!
  • Also, be aware that large jagged holes always look worse than they really are because their edges still show after being filled with putty or wood filler; so, if possible, smooth any ragged edges of smaller holes with a rasp, file, or sandpaper before filling them.
  • If your door has paneled rails or stiles, remove the screws in these parts of the frame so that you don’t split them when drilling holes for wood filler.

How to Clean an Old Door Knobs?

You Can Rejuvenate Your Worn Out, Tarnished Old Doorknobs Simply by Following a Few Steps:

The first thing you need to do is clean the surface of the metal with baking soda and water. Next, make a paste of these two materials and rub it on each knob, along with wiping it off with a dry cloth. This will help remove dirt, rust, as well as tarnish from your old doorknobs.

Do not apply this process if your old doorknob has plastic parts or crystal parts since they may be damaged by baking soda. However, if there are no plastic or crystal parts, you can proceed step-by-step below:

After thoroughly cleaning all the dirt and rust from your old doorknobs, you can start the actual rejuvenating process. This step will blend the old with the new by bringing back your own doorknobs to their original look:

You will need a bowl of cold water and white vinegar, and baking soda to achieve this. Both are necessary for this solution to work effectively. Ensure that in mixing them both, you mix up two parts of baking soda and one part of white vinegar. Also, you make sure that both these substances have been dissolved properly so they won’t create any problems when applied to your doorknobs later on.
