"X" is for X Base Circular Dining Table

Build: diy x base circular dining table

I built this circular dining table with an x base using plans from Ana White here and modified the top support and circular top.

I love the contrast between the sharp X angles on the base and the round circular shape of the top.

We're actually in our living room, a room that was hardly ever being used, so I decided to make it into an office space with an additional dining table for overflow and to have another work surface.

This table easily accommodates four adults but you could probably fit 6 people no problem.

I just love the chunky 2x6 construction combined with the 2x4 cross pieces that divide the table so neatly.

To get this smooth curved edge I used Rogue Engineer's tutorial here.  Jamison shows you how to build the jig for the router and make multiple passes using a spiral upcut bit.

And now we officially have another spot to do homework!  I definitely don't mind sharing my new workspace with my kids as long as they're being productive.

How to build an x base circular dining table:

1. Use Ana's plans here for the base construction with the following modifications in BOLD:

Cut List: 
2 - 1x4 @ 11 5/8”  15 3/4"
1 - 1x4 @ 26 7/8”  35"
2 - 1x4 @ 13 1/4”
1 - 1x4 @ 30”
1 - 4x4 @ 21 1/4”
8 - 4x4 @ 13” (longest point measurement, both ends cut at 45 degrees off square not parallel)
1 - 4x4 @ 36” (longest point measurement, both ends cut at 30 degrees off square not parallel)
2 - 4x4 @ 16 1/4” (longest point measurement, one end cut at 30 degrees off)
4 - 1x4 @ 5 1/4” (one end cut at 30 degrees off square, longest point measurement)
2 - 2x4 @ 14 1/4”  18 1/4"(one end cut at 30 degrees off square, longest point measurement)
1 - 2x4 @ 32” 40" (both ends cut at 30 degrees off square, longest point measurement, ends NOT parallel)
TOP is cut to fit

Step 1: Construct the base using the increased top support measurements.

Step 2: Construct the top using the 2x4 cross as your starting point cut the 2x6s to fit.  Use pocket holes in both directions and on the angled cut ends.  Be especially careful of where you place the end pocket hole on the last board (marked by yellow arrows), try to inset at least 7" so pocket hole won't be visible once you cut the circle.

Step 3: Make the router jig using Rogue Engineer's tutorial here.  It will take multiple passes with the router increasing the bit depth each time.  Definitely consider your jig board thickness before beginning: I used a 3/4" board for my jig and I couldn't get the bit deep enough to make the final pass on the 1 1/2" thick boards.  I ended up flipping over the table and making the cut from the underside.

A detail shot of the spiral upcut router bit results.  Clearly superior to any jigsaw.

Step 4: For additional support on the end curved piece attach 1x2 boards to underside.

Finish: I stained the table using a mixture of Minwax classic grey and dark walnut followed by clear wax.

  1. Jaime, this table is incredible. You did an amazing job. I think Rob is going to try and give this a whirl hopefully soon. We would love a circular dining table. :)

  2. You are really talented. Love the beautiful table you made. It's gorgeous!

  3. Do you think that this could be easily expanded to 60" round? Have you found the supports to be adequate?

  4. Thank you so much for posting the tutorial!! I just made the table and your instructions made it all so much easier! Jen

  5. hi... just wondering how much did it cost to make this table?

  6. What was the final size of the table?

  7. how many 2x6 did this table take to make?

  8. I used your plans and it turned out great. Fitting the pieces in the x took some extra boards it was hard to get the exact measurements but I got it done. Stained it grey and used apple green chairs. It is really cute.

  9. I worked on the base of the table today, following your adjusted measurements. I ran into a problem, though, when I went to add the 4x4s to the bottom. The measurements are definitely off. I went back to look at the measurements that were changed on your site, and the bottom measurements were increased, although the length of the 4x4 to attach to the bottom was not increased. Am I missing something? Thanks in advance for your help!

  10. @AllisonPrince Correct. I didn't change any of the 4x4 measurements from Ana's plans. Double check your adjusted cuts, the only measurements I changed are on the top support (table support) portion.

  11. I couldn't tell what type of wood you used. Was this all pine or cedar? If it was pine, how were you able to find untreated 4x4, did you need to go direct to a lumber yard?


  12. Hi, could we leave the base the same dimensions if using your plans to build a 70 or 72 inch round table top? If not, how many additional inches would you add to each piece on the base?
