Square Pedestal Table

Start by sandwiching the center 2x4s together with glue and nails. You'll need at least 2" finish nails here, but 2 1/2" would be better depending on what your nailer shoots. Keep outside edges as flush as possible, but remember that we will cover the sides with 1x4s in later steps ... so don't stress it too much!

Now mark and measure the placement of the bottom board and attach from underside. Glue and screws and make sure you are square to the center pedestal.

Then add the next board. Remember this one is the 30 degrees off square bevel. TIP: Use the boards from step 4 as a guide in placing.

Now fill in with the spare boards. When you go to finish the base, sand joint to create a nice pretty curve on the ends.

Now we'll start working on the top. Mark placement of top board and attach to center pedestal.

Mark placement of next board and attach with screws and glue.

Fill in as shown here. Use 2 1/2" screws and wood glue, keeping outside edges flush.

And then fill in your last boards, again 2 1/2" screws and glue.

Now let's trim out that pedestal with 1x4s to make a little prettier.

Cut with a jigsaw the curved pieces if using, and attach with screws and glue.

Let's move on to the top. I highly recommend building to first with a pocket hole jig on the 1 1/2" setting, using 2 1/2" pocket hole screws.

These are really decorative - you don't have to put them on, but to keep the look, nail the 1x2s to the underside.

And then add the 2x2 frame.

And finally, screw the top to the base! I'd leave the glue off here so you can dis-assemble/reassemble to move.
