The full-size table: The top is ready for sanding

table-top-glueup-3-all

Whew!

Today was time to glue up the two halves of the table top. I trimmed each of the two halves on the table saw, using the crosscut sled. Leaving each half slightly over final length, I tackled the glue-up. Sandy came to the shop to lend a hand, as I did not want clamps moving and lumber falling to the floor.

Three hours later I removed the clamps, scraped the dry glue, and completed preparations for sanding tomorrow. I will drop off this panel at my friend’s shop, and will wait for his call. He requested I write down final thickness, width, and length. I may not be able to share you this part of the job – but I hope to snap some photos of his shop.

Next: I will start milling the walnut legs, in preparation for glue-up; the legs will be 3 inches square, so I must mill two halves, and glue them to prepare the legs for final milling prior to machining the mortises on the FMT. I also have to mill some 4/4 (1-inch, rough) quarter-sawn white oak (QSWO), for the aprons; then to the FMT to machine the tenons.

I purchased gorgeous walnut and QSWO at Simpson & Sons, a large saw mill just South of town. The people at the mill go out of their way to help customers dropping in to buy one board, or a full truck load. Simpson has “… in stock walnut, maple, white oak, red oak, hickory, hackberry, red elm, and ash, and gun and rifle stock blanks.  From 4/4 to 8/4 we have all your furniture grade needs.  Planing is available on request. Stock lists and price lists are available by fax…”

The full-size table: Gluing up the top

After prepping the boards that will make up the table top, it is now time to glue them up. Due to their sheer size, I do this in stages, two boards at a time. Doing it this way removes much of the anxiety associated with large glue-ups.

I apply sufficient glue to get some squeeze out and, using several clamps while carefully lining up the edges as I go, I gradually start clamping down from the center toward the edges. When finished, I normally want a small bead of glue all along the glue line, on both sides of the boards being glued. I then wipe down much of the excess; and, when the remaining glue starts to gel, I scrape it off. The following photo shows one half of the table top immediately after tightening the last clamp; note the size of the glue bead I get (click on the image to enlarge it):

Once I remove the bulk of the remaining glue I check for flatness, using a good straight edge; the two glue-ups I did today were perfectly flat – a pleasing result after the work that has gone into these so far.

No doubt, the nice flat surface is the result of spending the time with a hand plane to touch up the board edges, in preparation for the glue-up.

Next: I will glue the two sets of boards I glued up today. At that point the entire table top will be ready for sanding to final thickness. Since I don’t have a machine that will take this huge slab, I will use a friend’s wide belt sander. Later I will use another friend’s slider to cut the top to final length on his table saw. I hope to document those two critical steps soon.

I think my newly-found muscles are starting to feel better. They ached for two solid days. And, to quote Peter McDonald, one of James Patterson’s characters, today “…everything was copacetic…” (1)

The full size table – the beginning

I received many e-mail messages about the half-scale table I made and submitted to the Lumberjocks Winter 2009 Woodworking Awards. As it turns out, I made two other half-scale models, to show a client for whom I will build a conference table and a stand-up desk.

The individuals from whom I received e-mail and questions in some of the woodworking forums wanted to know if the top, for example, will really be 1-1/2 inches thick. Yes, I am starting with 8/4 (rough) lumber; it will be a real workout. Everything about the half-scale tables was true to scale, including the mortise & tenon joinery.

In this entry I share with you how I approached the build of the table top. I will not have video, as this job is for a client, and I must keep totally focused. The photos will illustrate the entire process – and I can take photos as I consume a nice cup of tea while taking a breather.

If you have any questions about anything in this table build, please leave it as a Comment, or send me an e-mail message to sandal_woods@bbwi.net.

Ultimately, the table will be 30 inches wide, 60 inches long, and 30 inches high. The materials are quarter-sawn white oak for all but the legs; the legs will be black walnut. This table will be 2X the size of this one:

However, the bevel will change, to match the one I machined on the top board in this photo:

bevel-router-vs-hand

This is the table top, in raw form. The boards are 8/4 (about 2 inches thick) – the original design calls for top thickness of 1-1/2 inches; the top will be 30 inches wide, and 60 inches long:

The lumber for the aprons:

The lumber has been in the shop for two weeks. Now is the time to see the grain in the four boards will match. To find out, I planed both sides using a Stanley #3 hand plane, with the iron tuned with a little more camber than I normally like. This will allow me to quickly remove shavings to get a clear picture of the grain, including pattern, direction, etc. Since at this stage I am *not* flattening the boards, the #3 is perfect and fast for the job:

Hmmm…The 1/8-inch planing stop did not work, as the board is jumping over it – the board is not flat at this point. It is time for something a little more serious. Out came my new Gramercy holdfast (from Tools for Working Wood). When I first got these (I bought four), they did not hold well; I am certain this was my own doing, as my technique with a brace is not the best). And maybe the 3-1/2 inch bench thickness aggravated this issue. Long story short: I used a file to score several horizontal grooves along the shaft of the holdfast. Now it takes but one good whack! with a mallet, and they hold like crazy:

Now I could work at full speed with the #3. To my readers: Notice the logo just above the pocket on the tee shirt? Sandy can now embroider these! I may announce something new in the future:

After hand planing the four boards on both sides, I had to stop to clean up the mess. I will need a clean floor, to arrange the four boards – the table top will be quite a bit wider than my workbench:

This is better: Getting ready to look at the boards together:

shavings-a-mess

This is the payout of the hand-planing workout: I can determine the best way to cut the boards, for machining on the jointer and the planer. I just don’t like to machine all the excess lumber:

Now I have some boards of a more manageable size, with good preliminary grain match, and about 6 inches longer than the table:

After jointing and planing all surfaces flat, I now have two boards that are perfectly flat on the entire width and length:

two-boards-after-tweaking-edges

I had to tweak the edges on the boards, to get a spring joint and minimize the risk of a gap developing in time. For this I used a jointer plane, checking the fit as I worked. Here I am working on the third board::

tweaking-third-board-edge

I could not help it – I had to check out some of the boards I bought for the aprons – what else can I say? I hope this is not too much fleck:

If my muscles are still working tomorrow morning, I will continue work on this table top.
