Project Information

Dining table somewhat rustic in style yet refined in construction and finish. Features a 1" thick solid walnut top. Other elements are made out of red oak. The horizontal pieces of the leg assemblies also serve as a portion of the table top and are joined to the vertical pieces with massive bridal joints. The legs are 4" square. A top this size made of flatsawn walnut sees approx 1" of seasonal wood movement in my region. Because the leg assemblies pinch the top, all the movement had to be steered towards the middle, hence expansion joints were created in the middle of the apron pieces and in the leaf. The slides consist of extra heavy-duty drawer slides screwed to L-shaped hardwood pieces providing a very smooth operation and no sagging whatsoever. 30" high x 40" wide x 76" long. Extends to 94" long with a leaf. Finish is polymerized tung oil.

Very nice finish! My 8 year old son standing behind me also commented on the smooth finish of the top. I use tung oil also but never had a finish come out like that. A polymerized tung oil is somethiing I will look into. thanks for sharing.

Beautiful! And well engineered also! I like how the leg assemblies form part of the top. I have not seen that before.

Very very nice indeed! I will also have to take a look at polymerized tung oil. Does the polymerized tung oil come in a non-gloss finish? Can you do that, like matte or semi-gloss?

Also, expansion. Wow, 1 inch. But, doesn't it expand in the width direction, grain direction, or are you saying it expands in the length direction of the table? I"d like to know a little more about how you took care of the expansion problem please?

Answering Diamondback:

I use polymerized tung oil from Lee Valley. They claim that you can control sheen (satin/semi-gloss/gloss) by mixing different ratios of oil to tung oil sealer, which they also sell. I found that this does not work for me. I think it might be because I do build up the finish by putting on many coats ~5 and I leave a tiny bit of excess on every coat. The instructions call for a wipe on wipe off application, which would give an "into the wood" finish and perhaps the sheen method would work. I imagine you could try rubbing the finish to dull it a little but I have never tried it and don't know how well it would rub.

Regarding expansion now. Since solid wood expands in width and not in length, the walnut panels expand in width, which happens to be along the length of the table. From that point of view it is not different than most factory made solid wood dining tables since it is customary for such tables to have the grain in the top run at 90 degrees to the length of the table. The major difference is that factory-made tables have the top "floating" on top of the apron. With this table the top is pinched between the leg assemblies so I had to build an apron that can expand and contract with seasonal wood movement of the top. Hence the expansion joint. Have a look at the sixth picture I just added. Another expansion consideration is how to attach the extension mechanism to the table top. In this case I used screws in elongated holes in the mechanism.

Hope this helps.

Great! Thanks for the details! I also learned something new. I always thought wood expanded in the grain direction and not cross grain (duh, after all this time). lol I sure like your work though!
