It is so easy to replace old furniture hardware, drawer pulls and drawer knobs, with new drawer pulls or knobs.
HOW TO REPLACE OLD FURNITURE HARDWARE ON PAINTED FURNITURE
STEP 1. PREPARE THE FURNITURE FOR PAINTING.
When I remove the drawers from a chest or dresser I always number or make a note on the back as to placement of the drawer.
STEP 2. REMOVE THE ORIGINAL HARDWARE.
Use a screwdriver instead of a drill to remove the original hardware. The JTS likes to use the drill for this part of the project but I have more control with a screwdriver.
STEP 3. DRILL A HOLE FOR THE NEW HARDWARE.
I drilled one hole in the center of the drawer for the new knob. If you decide on a knew two hole pull and the width is different from the old furniture hardware you will need to measure and mark for two new holes.
Try to always mark and drill the screw holes exactly. It takes a lot of extra time and energy if the holes are off the least bit and you have to wallow them out so the widths between screw holes work.
STEP 4. PROTECT THE INSIDE OF THE DRAWER.
You may want to skip this step depending on how OCD you are. I cover the holes on the inside of the drawer with painters tape to keep the wood filler from seeping into the drawer.
