Large dining room table
5/24

So, I've built tables before, but nothing quite this size. It will be 7'-9" wide, and 16' long. I'll be building it out of reclaimed oak. The top will be 1 3/4" x 9 5/16" planks (yep, we will need several Samoans to lift it into place), and to make it worse, I think I will use iron channel to stabilize and strengthen the top. It will be rustic, and I will build the base in 3 sections and assemble onsite. I've got some ideas of how to attack this, but am posting this simply to solicit thoughts, suggestions, ideas, and comments. Thanks

Vikings?

Are you planning to join those giant planks or leave little gaps?
5/24 #5: Large dining room table ...

Hehe...or Vikings...
Yes, I will join them and glue them up. The wood is very old, and pretty stable. I am constantly checking rh and mc, so am not really concerned with that. If they have gathered moisture from somewhere, I'll throw them in the kiln for a few days. And I am in Utah, and the table will be staying in Utah, so pretty dry.

Is this a conference table or a dinning table? If this is for a dinning table they might want to rethink the almost 8 foot width as the only way to pass the salt across the table would be to throw it. A table that wide would also tend to stifle dinner conversation.

Aye, the wenches be dancin' on that table and you don' want them kickin' either food or drink at ye, eh?
5/25 #8: Large dining room table ...

You're doing the right thing joining them, however I find it very hard to successfully join planks that big with the equipment I have. Hopefully you're better equipped.
5/25 #9: Large dining room table ...

We did a mock up in place at their castle, and did check the reach across the table. We decided that we will also build a couple large removable lazy susans. The table had started out at 8-6x17, and they decided to shrink it some. I guess there are some family members who they don't mind not having conversation with, so they didn't want to shrink it too much. haha We also joked about having a shuffle board stick to push food back and forth.
I don't know how well my shop is set up for this either, since this is the largest I have built, but thank goodness it's "rustic" that will hide a few sins anyway. ; ) Thanks guys

I always kringe when I read about strengthing wood with steel. I don't know anything about your weather, but won't there be swings in humidity some time of the year? Maybe you are planning on slots to let the wood move. And isn't that over 800 pounds of wood, just in the top. Can't imagine trying to start a 90 pound board on the jointer, with 13' hanging off the bed. Sure hope that stock is straight line ripped.
5/27 #11: Large dining room table ...

Kris Kringe agrees - no steal.
5/28 #12: Large dining room table ...

Hi, seems like move the tools to the wood instead oif the wood to the tools! I am thinking straight edge( aluminum angle works good, no harm if router nicks it), then clean edges, then drill and add dowels, then drill and use threaded rod, but but some die springs made for tool and die jobs, this will be the expansion contraction "give", plug the edges where the threaded rod is? then hand power plane / sand? free advice! use it as u see fit!
5/28 #13: Large dining room table ...

Wow! Awesome contribution, thanks! So now to details. This wood is over 60 years old, and is actually pretty dang straight. I will need to join them, just to clean up the edges a little, and have built a long jig for the joiner that was used for building large box beam material. I was going to use steel channel and let it in with a plunge saw into the bottom of the planks, after using a festool domino to join the edges of the planks. The channel would be screwed to the planks from underneath. I would build the table in two halves lengthwise (3-5 3/8 x 16'-leaving one plank out, as my wide belt is only 43"wide), run the two halves and the plank through the wide belt sander, then join the two halves and the extra plank together and hand plane and hand sand the center seams to finish. The skirting would be pocket screwed to the underside of the table, and the legs are difficult to describe without a sketch, but they will be double decoratively bandsawn square legs on a single wide food with stretchers in between them. The foot on the bottom and a board on the top that will be screwed to the underside of the top. I will do three of the leg/foot components on near each end, and one in the center. The stretchers connecting the feet will be mortised and tenoned into the feet. I had planned on two steel channels in between the three leg/'foot components for extra stability. So that's the plan, but I'm not too proud to change plans based on good contribution. Thanks again.

The problem I have encountered with the kind of thing you're doing -- in addition to the awesome task of schlepping huge planks etc -- is that "pretty dang straight" isn't straight enough to make a consistently seamless glue joint -- and if 85% of the top is seamlessly glued and the remaining 15% doesn't quite join, it looks like a mistake. But hopefully your jig will enable you to join it perfectly. I know first hand there is a market for these monsters and not only to Vikings.
5/28 #15: Large dining room table ...

Point taken. Do you think I'd be better off straightening and cleaning up the edges with the Festool tracksaw? I have enough track to reach the length.
The one "out" that bounces around in the back of my mind is that it is "rustic" and many of the "mistakes" can be disguised as such. That's what we've done hundreds of times on lots of different projects. We don't use it as an excuse for inferior workmanship, but sometimes we are dealt character inherent to the old wood, and add to that character with our methods. Maybe that sounds like a lame explanation, but things have really turned out very cool in the past. I suppose we could invest thousands of dollars to improve the shop to the point that all was perfect, but...Idk, seems like we'd lose some of the charm, and start to creep into things being obviously machine made. In the past, we've been able to achieve the balance without it looking crappy. I'm kind of hoping we can achieve the same results even on a massive table.
5/28 #16: Large dining room table ...

I know what you're saying, Ron. We do the same thing.
5/28 #17: Large dining room table ...

You have checked on the size of the front door of the house haven't you? Getting an 8' wide table carried by carts and 8 people will surely be a project.
5/28 #18: Large dining room table ...

Hehe...it's a drawbridge...; )
6/3 #19: Large dining room table ...

Ron has it exactly right. You take what the wood gives you.Any imperfections can be explained as "charachter". Sounds like it will be very nice,,JD
6/3 #20: Large dining room table ...

Yep, and "charachter" seems to go hand in hand with giant tables.
I have built large oak tables, but I used quartersawn white oak. I edge glued the boards, built a French country style base and after a decade the joints are still tight. I allowed for expansion and contraction of the top.
Wood is plenty strong - I see no need for metal to be included in the top.

I made a large conference table,4ft x 13 ft. To make the glue jonts I use the festool saw on the track and than 10mm dominoes about every 8 inch apart. To keep the table straight and from cupping I mounted iron bars under the table, they are V shaped with a horizon tall extention at the top on each side of the V that have longitute slots for the wide flathead screws(for expantion or contraction)
6/16 #22: Large dining room table ...

Plan ahead. You may need to import the Samoans from Vegas. ^^^
1/22 #24: Large dining room table ...

I think you should think once more on the size. After you glue the edges properly and dry them, decorate it with candles and a vase of red and yellow rose.

WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.
Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).
Libel: Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.
Improper Decorum: Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).
Advertising: The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).
Repeated Forum Abuse:
Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.
There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards.
