How to install a wood table leg/furniture leg is not very different from installing a metal table leg/furniture leg. The primary difference in many cases is that the wood table leg/furniture leg will not be pre-drilled for installation on a mounting plate or threaded bolt. This is not always the case, but does occur frequently. This gives you more freedom for how to install a wood table leg/furniture leg on a mounting plate or threaded bolt of non-standard size. If you have experience in woodworking and feel comfortable drilling your own hole in the wood table leg/furniture leg, I say go ahead as this will save you time and money. If your only experience with woodworking is assembling an IKEA bookcase (and even that didn’t go well) I say save yourself missing fingers and a trip to the hospital and contact a reputable carpenter or other experienced woodworker in your area. For such a small task, I’m sure the carpenter would appreciate if you brought the wood table legs or furniture legs to their shop rather than having them make a trip to your home. You’ll also save some money not having to pay for a home visit.
If your wood table leg/furniture leg will be installed on furniture that does not already have its own mounting plate or threaded bolt for installation, I would recommend going with an M10 thread. This is the standard bolt size for table legs/furniture legs and will save you a headache in the future if you decide to switch to metal table legs/furniture legs or swap out wood table legs/furniture legs. Now that your hole is drilled in the wood table legs/furniture legs and you have your M10 (or other size) mounting plate or threaded bolt, you can continue with your installation. Screw your mounting plate or threaded bolt to the underside of your table or other furniture. I’m sure I didn’t have to tell you to flip your furniture upside down to make this easier. If you’re just now flipping your furniture over, no problem (I didn’t see a thing). Continuing with your installation we reach the last step where you will screw your table legs/furniture legs onto their respective mounting plates or threaded bolts. Make sure the table legs/furniture legs are secure, but do not over tighten them. You don’t want the wood to split. Your table leg/furniture leg installation is now complete. I don’t have to tell you this, but for the sake of my own conscience I’ll advise you to now flip your furniture over onto its new legs before using it. Using your furniture upside down negates all the hard work you put into installing your table legs/furniture legs. I’ll end these installation instructions the same way Pop Tarts instructions are written. Cool briefly before handling. I know it doesn’t make sense, but I don’t care. It’s Christmas. If you’re reading this in April, this really makes no sense. Why am I still writing this? Enjoy your new legs. Cool briefly.
