Hello all, long time lurker, first thread.. I'm a mechanical engineer just building my shop up. I graduated a few years ago and now am working in the oil patch. I have been working on a solid maple coffee table for my wife for a few months now off and on. It is loosely modeled after the Pottery Barn "Benchwright" line of tables: http://www.potterybarn.com/products/benchwright-coffee-table/.

After reading up on the quality of their furniture and feeling the general heft (or lack there of) I assumed I could build one using the old techniques - mortise and tenons, solid wood, breadboard ends, etc. Unfortunately I don't have too many pics of the actual construction of the pieces. I learned 99% of how to make tenons and mortises from youtube and various woodworking forums. I'm a firm believer that the everyday guy can produces work that has 95% of the quality of a true craftsman if he is devoted to patience and works and studies the craft.

Now, back to the "build." I bought the maple surfaced S4S, meaning surfaced-4-sides. This was because I did not have a planer, hand planes, jointer or anything else to really straighten wood. It's from a local mill - great guys - and I wouldn't recommend anyone tackle something like this with wood from a big box store... I built the rest with a 12" Ridgid compound sliding miter saw, a Ridgid worm drive circular saw, a 1HP Craftsman router and cheap router bits and a Craigslist Craftsman drill press. I built a lot of jigs out of 1/2" mdf to route the mortises. I also built a mini router table that clamped to my regular table (which I also had to build to have something to clamp it to..). I used the Incra rulers to lay out the mortise lines (thanks to the Aerodrome studio for that), routed them with 3/8" plunge bit.

The tenons were cut on the router table using a rabbeting bit. I ended up rounding half the tenons over and squaring the mortise corners. I found that generally for me, squaring the mortises was easier. Also, a good, SHARP, set of chisels was invaluable for this project. Sharpen them often and they will work for you.

The top is made from 1 5/8" maple, roughly 6" wide. They were joined using a boatload of 1/2" dowels. I drilled the dowels using a cheap jig from Rockler and a hand drill. The breadboard ends were one of the most difficult things to make. They have a long mortise that is 1/2" wider than the tenon on the table runner boards. They were attached using glue in the middle and drawbored with 3/8" oak pegs from the bottom. Fantastic way to attach a "floating" piece of wood that I learned about, naturally, on the internet.

The bottom shelf is made from 3/4" maple with a :gasp: mdf center piece. Now, critics beware - I don't feel like I ruined this fine furniture by using mdf. Here's my reasoning: 1) I needed a piece that was 1/8" thinner than the maple boards. This is because there will be a 1/8" steel strap running lengthwise down the shelf. This is part of the "industrial" look that she wants. 2) mdf, when used and attached properly is very dimensionally stable - meaning it won't expand with changes to temperature and humidity. This was important to me as the steel strap will be laminated to the mdf. I didn't want the substrate to be expanding when the steel wasn't - leading to cracks. I live in Houston, we have wild changes in humidity and temperature, everything needs to be able to float and move.

On to the pics - any questions please ask. Next I'll show how I'm attaching the turnbuckles and threaded rods, attaching the top using the "old" method and finishing/sealing.

That's a beauty. Those breadboard edges are a real bear to build. I did one on a kitchen table once, and I'll never build another one.

Thanks and Gig 'em!

@Steevo- agreed regarding the breadboards... next time I'll learn to love open end grain and just skip that step.... btw, love your work bench, I had something similar in mind - think I'll just steal your idea...

I just built the same thing for my wife. You really went the extra mile with the mortise and tennon joints . Very nice! I used all pocket hole screws and finish nails.
Nice job it looks really good

Two more: detail of leveling feet hardware recessed into each leg. The second is just a snapshot of the plans I originally drew up on drafting paper.

Detail with some finish on the table and of the 5/8" turnbuckle assembly.

Turnbuckle was from McMaster - stub/stub. Interestingly I could only find left hand nuts in a plain finish... To get right-hand threaded nuts online one usually had to buy in bulk, i.e. 50 or 100 count... I only needed 4..

So, off to big box store to buy some nuts and some muriatic acid to remove the zinc plating. Tip here: use gloves, ventilation, goggles and caution. The muriatic vapor will do two things: 1) lock up your lungs (experts comment here) and 2)rust all of the metal in comes into contact with. I recommend doing this outside at a working height that way you are not bending over a jar of acid.

I just used a plastic paint cup, poured in some acid. Slowly lowered in each nut with a copper hook. Let them "simmer" for about 15 minutes. They will come out with all of the zinc plating removed. Neutralize with baking soda/water. Immediately coat or they will tend to flash rust.

Forgot to mention... naturally, SWMBO took one look and hated the color... Naturally she picked it, approved the test panels and OK'd final staining...

Large amounts of sanding are now in order...

Any finished pictures? I enjoyed skimming through your blog (haven't had time to fully read everything yet)... and thanks, now I want to go get a welder!

This is very nice project.

I built a full-size dining table out of cherry using only hand hand tools for the joinery. Breadboard joining is not that bad done with hand tools.

The fun part for me was planing the 42x72 top with a No. 8 plane; that was a real workout.

You can attach the top to the frame with shop-made wood cleats that go into routed slots that allow the top to move (old school). You can also buy these in steel.

I don't know if you know this, but hard maple takes a more uniform appearance with dyes (Transtint) instead of pigment (Minwax stains). As for the topcoat: waterborne, wipe-on poly or lacquer will all be fine, just be sure not put hot items on the top. You can even apply shellac (old school).

Have fun.
