DIY Large Outdoor Dining Table - Seats 10-12

I have been wanting a large outdoor dining table FOREVER! So, to celebrate turning the BIG four-zero, I decided to build myself one. :-) Happy Birthday to me!! I finished it just in time to have my family over to celebrate my jump into middle-age. Except for my daughter’s birthday celebrations, we usually just have a family dinner to celebrate mine or my husbands b-days, which usually means we have 11 or 12 family members over for dinner (including us). So, I HAD to have a table that would fit said 11 or 12 people of course, so build one I did, and I must say I am absolutely LOVING it!
For the table top, I modified plans from Shanty to Chic and Ana White to create a longer table, and then I built my own base by looking at elements from other DIY tables, and creating my own design. Here are some pics of how it turned out:
Materials List:
14 – 2x4x10
4 – 4x6x12
wood glue
Kreg pocket hole jig
2 1/2″ pocket hole screws
2 1/2″ exterior wood screws
countersink drill bit
wood stain
exterior spar urethane varnish
Cut List
Table Top:
5 – 2×4 @ 105 1/2″ each
4 – 2×6 @ 105 1/2″ each
2 – 2×4 @ 108 1/2″ each
2 – 2×4 @ 43 3/16″ each
3 – 2×4 @ 39 1/2″ each with each end cut at 45 degree angle
Table Base:
8 – 2×4 @ 17″ each, with each end cut at 45 degree angle
4 – 2×4 @ 24″ each
4 – 2×4 @ 6″ each
2 – 2×4 @ 30 5/16″ each, with each end cut at a 45 degree angle
2 – 2×4 @ 33 7/16″ each, with each end cut at a 45 degree angle
2 – 2×4 @ 35 11/16″ each, with each end cut at a 45 degree angle
1 – 2×3 @ 68 1/2″, (cut 2×4 to 68 1/2″, and then rip board down to 3″ wide on table saw)
Here are the basic instructions, detailed plans are available on the blog at the link below.
First build the table top:
Cut the 2x4 and 2x6 boards for the top and place the boards into position on a large flat surface.
Cut the support boards and attach to the bottom of the table top using wood glue and 2 1/2" wood screws.
Cut the boards for the table top trim pieces and attach using pocket holes and pocket hole screws.
Next, build the base.
Cut the boards to the correct lengths for the feet and attach using wood glue and 2 1/2" wood screws.
Cut the boards for the legs and attach with pocket holes and pocket hole screws. Next attach the legs to the bottom of the table and add in the cross support board.
Then cut and add the other cross support boards using wood glue and pocket hole screws.
Lastly, cut the boards to create the diamond shape design on each leg and attach with wood glue and 2 1/2" wood screws.
Now, sand, stain, and coat in varnish and you have a beautiful, large outdoor dining table!

    Did you leave space between the boards on top to allow water drainage? If you didn't have you had issues with water setting on the table top?

    The materials list, calls for 4- 4x6x12, did it mean to say 4-2x6x12? When you look at the cut list it doesn’t say anything about a 4x6x12.
