How to Install Caster Wheels
Caster wheels are small wheels attached to many different types of household and industrial items to allow mobility and ease of transport. You commonly see them on tables and office chairs, but they are also used on industrial carts that bear a great deal of weight.
Caster wheels are a great help inside any home or office, and knowing how to install them can add to your home improvement skills.
Look at the item on which you want to install the caster and decide if you want it to move forward and backward (using a rigid caster), or in any direction (using a swivel caster). Choose the spots where you want to install the wheels and count the number of wheels needed. Installation spots must have a flat surface and must have sufficient surface area to hold the wheel's top plate. Consider the weight of the object that will use the wheels.
Buy the type, size and quantity of caster wheels that would suit your requirements, including the screws that would be needed to attach the wheels (wood screw for wood; metal screw for metal surface). Caster wheels come in many forms, materials and with varying features. Although differing in material and style, almost all caster wheels serve the same basic purpose. Ask your local store clerk regarding recommendations on what type of wheels would be best suited for your project.
Lay the top plate of a wheel onto the flat surface on your desired installation spot. Align the orientation of the top plate according to your desired position, but make sure that the plate fits on the surface. Mark the location of the four holes on the top plate using a pencil and draw an outline of the top plate by marking along its sides.
Score the centre of the pencil marking using a centre punch and hammer to hold the tip of the drill bit in place until it begins to cut the wood or metal and to prevent the drill bit from slipping out of place. Drill a hole on each mark using the correct size drill bit for the screws (preferably one size smaller to make a tight fit) and an electric drill. Use the correct type of bit for the type of surface you're working on. Make sure each hole is drilled on the exact spot where the markings are.
Lay the top plate of the caster wheel onto the surface of the drilled holes, fasten the screws into the holes, and tighten firmly, using a screwdriver. Repeat the steps for each caster.
