WHY WE SHOULDN’T SCREW LEGS TO OUR TABLE TOPS?
Live edge wood is very sensitive to changes in humidity. With natural wood, if exposed to extreme temperature changes, they can potentially warp and/or split. Thus, all the woodworkers need to be very careful to install hardware to the wood tabletop such as screws.
For that reason, we only can recommend to all customers to use "thread nut and bolt", it would be a safer way to hold the table. In case of timber table top, lumber table top, oval table top, it will be no problem to use screws for fitting
HOW TALL SHOULD MY TABLE BE AND WHERE DO I MOUNT MY TABLE LEGS?
A dining table should be 30” tall. Make sure you order the correct legs based on your particular top. There is a big difference in a 1.5” top and 3” top when the same legs are attached. Many steel bases come with adjustable feet to give you a 1/2” or so of wiggle room.
Most people want the option to seat someone at the ends of the table as well as the sides. So I recommend a minimum of 16” from the end of the table to the front of the table leg to allow for a chair to be pulled up. If your table is over 96” you can push that back to 18-20”.
HOW TO ATTACH METAL LEGS TO WOOD TABLE?
Step 1: Set the metal legs in place. Take a brad point bit and hammer/mallet and just tap the bit in the middle of each hole. The brad point bit is nice because it fits tight in your slotted hole. So you know the center of the bit will be in the exact center of the hole.
Step 2: Drill your hole straight up and down. You don’t want your insert going in at a 30-degree angle. If you don’t have a stop collar, a piece of tape works as a good depth reference. Just drill all your holes at once.
If you want to go a step further, you can add blue threadlock to your bolts to make sure they don’t wiggle loose. Paste wax or nylon washers can also assist in letting your bolts glide across the base plate.
