Coffee Table, Part 2

Last time I finished up the apron and drawer assembly and putting the taper on the four legs of the new coffee table.  Now that the apron was finished, I could fit the legs to each corner.  This involved sizing the thickness of the sides of the apron and transferring the measurement to the legs, then removing that with the big saw:

Then came the fun part: working the tabletop.  I started with the aforementioned big ole' slab of oak...

...and cut it in two...

...jointed the adjacent edges and glued them together:

Then I just used the circular saw to cut the length and width that I needed:

A lot of planing later, the top was smooth, flat, and showed a fair amount of figuring in places:

Jointing the edges of a slab this big is a little more difficult that most pieces.  Planes are meant to be used at belt height which wasn't really doable here:

I then started putting the bevel around the underside; here's one edge complete:

The process starts by using an angled fence on the skew block plane to establish the angle of the bevel.

The jointer and fore plane then taken that bevel even further down...

...which provides a good foundation for the scrub plane to come in and hog out lots of stock.

I then come back with the jointer and then the smoothing plane to finish the edge.

I couldn't wait to see what the stained top would look like, so I went ahead and put on a coat or two.
It became obvious that the surface wasn't quite smooth enough yet.  If you look closely at the above photo you can see plane tracks running across the top.

Only one thing to do...
...plane it down and start over.  The next time I finished it off with a cabinet scraper and it worked out well.

Next I made the brackets that hold the top to the apron.  This just involved planing a rebate into a piece of wood...
...cutting that wood into little blocks...
...and installing them in the groove running around the inside of the apron.  Screws driven through these blocks and into the bottom of the tabletop hold everything together firmly but still allow for seasonal wood movement.  Here you can also see how the legs are attached...glue is involved too.

The oak is stained with Minwax "Chestnut Red" and the tabletop has some polyurethane on it.  The maple is rubbed with Watco Danish Oil in "Golden Oak."

In situ:

With the installed drawer pull.
Really ties the room together, does it not?  Or could that just be the rug?

The Crappywood Challenge

I'm on a mission.

Rid the house of particleboard


My wife has a lot of books.  
These books need homes.
Sagging particleboard shelves are unacceptable.
Off to the wood dealer I go.

This time I wanted to check out Peachtree Lumber up in Kennesaw. They had an enormous inventory of hardwoods including a "bargain bin." The bargain bin was actually a large area with lower grade hardwood to be had for a lower price. I walked out with I bunch of walnut for $2.54/bd ft. and "paint-grade" maple for $1.50/bd ft. 

Have a look:

The walnut is beautiful, wild-grained wood; but that's part of why it's so cheap. That crazy-grained, flat-sawn wood fights you every step of the way when you are working it...particularly if you are a hand-tool guy.  Power tools can usually blow through irregularities but hand tools have issues at times...we'll get to that. 

The white maple was to be the shelves and the walnut was to be the casework. I decided to knock the shelves out first and build the case around them. This runs counter to a strategy that I'm trying to employ of building from the outside in.  In this case I was material-limited so I had to plan very carefully around the limiting dimensions. I knew I had to have 5 shelves for this piece, so a defining dimension of the bookcase was however much I could get from the wood I had. Obviously the planks I bought were a little narrow for shelves, so that meant a long-grain butt joint...you know where this was going: tongue and groove.

Done...

...and done.

Note the tiger figuring on some of this wood:
Very nice, but a pain to work with. Essentially the grain does a little shimmy on each stripe and that makes getting a smooth surface difficult with handplanes.

But that was nothing compared to the walnut:
At least in the above specimen, the grain direction is decisive: first it's one way, then it's the other. On other pieces it was back and forth and back and forth. No fun: tear-out all over the place. But I got it smooth eventually by edge planing short sections in one direction and then hitting it from the other side.

So the stock prep got done...time for construction. It's a very simple design: the case will be dovetailed together, shelves fit into dados, and a nice face frame attached via loose tenon joinery. Simple stuff.
DTs:

The size of these pieces did present some problems to which I was unaccustomed. For example, pin layout had to be done sideways and without a vise...

...and pin cutting had to be done with me on top of the workbench:

But all's well that ends well.

Now time to fit the shelves. Here you can see the length of the shelf relative to the casework:

...not quite halfway overlapped: all good.

Here's how to rout dados for shelves: clamp the two side pieces together, clamp a straightedge normal to them, rout your dados:
I'm going to use this little space here to proclaim how much I love Bosch tools. They're such a pleasure to use. No funky styling either...just function...so nice.

My largest router bit is 3/4", the shelves are a little more.
Dangit

Not a big deal though. I could've power-planed all the shelves down to .748" but that would've been really loud; and since good music was on the radio at the time I took another course:
Oh, skew block plane, I do adore thee.

Fast forward to four shelves later: time to start thinking about the face frame. More long-grain butt joints. I decided to employ the old floating tongue technique that has gotten me into so much trouble in the past. What can I say? It's bound to work some day. Grooves plowed:
Uh-oh, that's no good:
Looks like a groove is exiting and will be visible. That's not really good form. Actually I anticipated this and considered busting out a mitered dovetail joint, but that's a joint that I need to practice a bit more before executing on a live piece. So I'll deal with it. It's not that big a deal:
...and done:

At this point the case was just three pieces of wood joined together with two joints: two sides and a top. I needed a brace on the bottom. My idea was to just attach a brace with exposed through dovetails flush with a bottom shelf. Here is one of the receiving tail sockets in the face frame:
Anyone see a potential problem? Yeah, because these sockets are oriented along the grain instead of in end grain, they are super delicate. Once everything is assembled it will be strong, but getting it there could be disastrous. And it was.

I tried a nice slow, steady assemblage with clamps slowly sliding the tails into place:
And it snapped that middle tail right off. Darn. So I screwed-and-glued it back in place.
All good:

Then I did the other side, this time with a preemptive screw in the middle tail.

That's no good.

That's even worse.

Time for emergency patchwork and a beer:

I used my dovetail layout guide to define the shape of the bookcase feet. This angle jives nicely with the nearby patched up dovetails. Notice how the right side of the guide is aligned with the edge of the wood: this is a trick I use all the time in layout. Doing this facilitates easily repeatable spacing around the rest of the piece.

Here's the exact same spacing repeated on the brace:

A little satin wax to bring out the depth of the grain...

Now we're getting somewhere!
I should do a commercial for Minwax:
