Entry hall table for a niece

[Derek Cohen (Perth Oz)]

I thought that the build might begin with preparing the panels, since there has been some interest in the past shown in the shorter Hammer K3 sliders. Mine has a 49" long slider and a 31" wide table for the rip fence.

The build is an entry hall table for a wedding present for a niece. Her choice was this mid century modern piece, which will be the basis for the build. My job is to re-invent it somewhat.

She wants Jarrah, and I have managed to find something spectacular ... a subtle fiddleback (curly) set of boards that will make a book match (as they are only about 9" wide each).

Most imagine that the value of a slider lies with cross-cutting. It certainly is so. However it is the rip using the slider - rather than the rip fence - which is so amazing.

One side of each board was to be ripped on the slider, before being jointed and resawn. Ripping on the slider is such an advantage with life edges. No jigs required. No rip fence to slide against. Just clamp the board on the slider, and run it past the saw blade. The long sliders can complete the rip in one quick pass. It occurred to me that I should take a few photos of ripping to width since the boards are longer than the slider.

Here you can see that it comes up short ...

In actuality, with the blade raised fully, there is a cut of nearly 54" ...

The solution is to use a combination square to register the position of the side of the board at the front, and then slide the board forward and reposition it ...

... and repeat at the rear ...

The result is a pretty good edge, one that is cleaned up on the jointer in 1 or 2 passes, and then ready for resawing ...

This is the glued panel. It is long enough to make a waterfall two sides and top section (still oversize) ...

The following photo shows the lower section at the rear. What I wanted to show is the way boards are stored. Since I shall not get back to this build until next weekend, all boards are stickered and clamped using steel square sections.

The steel sections are inexpensive galvanised mild steel. These are covered in vinyl duct tape to prevent any marks on the wood and ease in removing glue ...

Done for the day ...

Enough for the case (top/bottom and sides), which will be through dovetailed with mitred corners, the stock for 4 legs (yet to be turned), and rails for the legs (the legs will be staked mortice-and-tenon) and attached with a sliding dovetail.

Hi Derek,
Looking forward to another of your superb WIP.
I too have a slider with about a 54” capacity. To extend it, I use a carrier board that has a strip mounted underneath it that fits exactly into the slot. The board to be cut is secured on top of the carrier board and both are slid forward to achieve a longer cut.

Hi Derek I’m 44, my name is Fitzroy and I’m a great guy. I’m hoping you like to adopt me as a family member and make me an awesome piece of furniture!

Looks great already, roll on the wip.

Fitz.

The WIP has barely begun, yet you have already shown us a clever detail for the weekend woodworker that I have never seen mentioned before - the tape-covered steel to keep the precious boards properly stacked and clamped flat between sessions. Nice one!

Hi Deema

I have a kit from Felder for building a sliding table on the slider. Its use is, in my understanding, primarily for sheet goods since it will reduce the cutting height by the thickness of the carrier board.

Derek,
I always enjoy your projects and this one looks to be very promising too. The Jarra is beautiful.

We are building a version of this hall table ...

We left off last time with basic preparation of stock from rough sawn boards ..

A word of introduction before continuing: while I am best known for hand tool work, I am a blended woodworker and have a pretty full compliment of power tools, which I use. It is horses for courses - power does the grunt work and hands do the details and joinery. So there are machines here as well as hand tools, and I like to believe they coexist well in my builds, as they should.

I began this session by turning the legs ...

The Jarrah for the legs turned out a few shades lighter than expected, and I made an extra piece to experiment with different dye mixes. A final decision shall be made once the case is completed.

The panels needed to sized, which involved measuring from the centre line of the book-matched panels. The quickest way to square this up was to mark a line (in blue tape), and plane to it ... much faster than using power saws, etc.

Once done, you can square up on a jointer ..

... rip to width ...

... and cross cut ...

Here are the panels for the case (sides yet to be dimensioned for height) ...

Packed away for the night ...

When marking the dovetails, it pays to work precisely. Mark carefully ...

My favourite dovetail saw is usually the one I sharpened most recently. This is an original Independence Tools saw by Pete Taran (circa 1995) ..

Completed side panels ...

It begins to be a little more fun as I get to use one of the features I recently built into my new Moxon vise - the Microjig clamps (details of Moxon vise here: http://www.inthewoodshop.com/ShopMadeTo ... Moxon.html).

These are used to hold the tail board to transfer to the pin board ...

Here you see the transferred tails outline in blue tape (easier to see in the hard wood). On the left is a model of the mitred ends that will be part of this build ...

Saw the pins ...

Note that the end pins are not sawn on the outsides.

Now turn the board around, and strike a vertical line at the outer pin ...

Saw this on the diagonal only. Do both sides ...

Place the board flat on the bench and create a chisel wall for each pin (earlier, this would have been done for each tail) ...

The chisel wall will make it easier to create a coplanar baseline when removing the waste (by preventing the chisel moving back over the line). Do this on both sides of the board before proceeding.

Now you can fretsaw away the waste.

Try and get this to about 1mm above the baseline ...

Here is a video of the process:

To create the mitred ends, first mark ...

... and saw about 1mm from the line. This will later be flushed with a chisel for accuracy.

And so this is where we are up to at the end of the weekend ...

So will the sides fit ... or won't they .... mmmmm

Are there side bets? Odds?

In truth ... it is a lot like like Christmas morning as a kid ... the result is never a foregone conclusion. The element of surprise is always there.

I've been away from the workshop for a month, travelling around a few cities in Austria and Germany, as well as Prague. It was a good trip, but it's great to be home.

The current build was on hold. This is the entry hall table my niece asked me to build ...

... and this is where we left off last time - ready to fit the first corner ...

Past builds:
Part 1: http://www.inthewoodshop.com/Furniture/ ... iece1.html
Part 2: http://www.inthewoodshop.com/Furniture/ ... iece2.html

Today we shall put the complete case together. What I wish to focus on is the dovetailing. Not just any dovetailing, but mitred through dovetailing in unforgiving hardwood (here, Fiddleback Jarrah).

Of all the commonly used dovetails, I consider the through dovetail more difficult than the half-blind dovetail. Why ... because two sides are exposed against the single face of the half-blind.

In my opinion, by mitering the ends, the level of complexity is tripled .. at least. Not only are there three faces now, but each needs to be dimensioned perfectly, otherwise each is affected in turn.

This is more difficult than a secret mitred dovetail, where mistakes may be hidden.

I have posted before on building the mitred though dovetail, and it is not my intention to do this again. Instead, what I wish to show are the tuning tricks to get it right.

This is the model of the tail- and pin boards …

In a wide case, such as this, it is critical that the parts go together ideally off the saw or, at least, require minimal adjustment. The more adjustments one makes, the more the dovetails will look ragged.

Tail boards are straightforward. Let’s consider this done. Once the transfer of tails to pins is completed, the vital area is sawing the vertical lines … well, perfectly vertical.

I use blue tape in transferring the marks. The first saw cut is flat against the tape. Note that the harder the wood, the less compression there will be, and so the tail-pin fit needs to be spot on. Where you saw offers an opportunity for ensuring a good fit: if you hug the line (edge of the tape), you get a tight fit. If you encroach a smidgeon over the line, you loosen the fit slightly.

Saw diagionally, using the vertical line as your target …

Only then level the saw and complete the cut …

I do not plan to discuss removing the waste. That was demonstrated in Part 2.

So, the next important area is the mitre. These are scribed, and then I use a crosscut saw to remove the waste about 1mm above the line on both the tail- and pin boards …

Now we are ready to test-fit the boards …

Mmmm …. not a great fit …

… even though the mitres at the sides are tight …

The problem is that the mitres are fat, and the extra thickness is holding the boards apart …

Even sawing to the lines here is likely to leave some fat, which is why it is a waste of energy to try and saw to the line in this instance. It needs to be pared away with a chisel, using a 45-degree fixture.

As tempting and logical as it seems to pare straight down the guide …

… what I experience is that the chisel will skip over the surface of the hard wood rather than digging in and cutting it away. What is more successful is to pare at an angle, and let the corner of the bevel catch the wood …

This is what you are aiming for …

Okay, we do this. And this is the result …

Not bad. But not good enough. There is a slight gap at each side, quite fine, but evident close up.

The source is traced to the mitre not being clean enough. It is like sharpening a blade – look for the light on the edge. If it is there, the blade is not sharp. If there is a slight amount of waste on the mitre, the case will not close up.

To clear this, instead of a chisel – which is tricky to use for such a small amount – I choose to use a file. This file has the teeth on the sides ground off to create “safe” sides.

Try again. The fit is now very good. I will stop there.

So, this is the stage of the project: the case is completed. This is a dry fit …

One end …

The other …

The waterfall can be seen, even without being smoothed and finished …

Nice, Derek.

In the same way that shoulders can be undercut, so can the mitres. You have two edges (top and outside face) which will be on show and have to be perfect, but the rest could angle away slightly on both pieces (tail and pin boards). Particularly in a hard wood like jarrah, taking the carcass joints apart repeatedly to adjust is an absolute pain, so removing one possible area of mis-fit might reduce the risk. Obviously you couldn't do this if the corner/ edge was to be rounded over, as I think you did in your last jarrah table.....but then you probably wouldn't have mitres anyway.

For English woodworkers, you have no idea just how damn hard jarrah is. It's sort of like working in steel. You couldn't drive a nail into it without a pilot hole. I've fiddled about with bits of it in my dad's workshop when I was a kid in West Australia, and a couple of pieces as an adult, but I dislike the colour as well as the difficulty of working it.

 

[AndyT]

That's a good point. Jarrah used to be imported to make beds of lorries where it stood up to all sorts of heavy abuse.

Thanks Mike. It is not just that Jarrah is hard; it is also brittle and this example is very interlocked. But I am used to it, and the fiddleback in this piece is spectacular.

In the current build it is not possible to undercut the mitres to make them fit. The reason is the inside edge on the model calls for a bevel/mitre all the way around. I plan to do a slight cove. In any event, this open up the mitre from the inside, and any undercutting would show.

[Derek Cohen (Perth Oz)]

Having completed the dovetailing of the case, the next step is to bevel the front face, and rebate the rear for a back panel.

I had been considering a cove in place of a bevel, however when I mocked this up it came across as appearing too busy. So, back to the bevel.

The angle for the bevel was finalised at 55 degrees. This enabled a 6mm (1/4") flat edge and a bevel that ran to roughly 4mm of the first dovetail. A 45 degree bevel would run into the dovetail.

The lines for the bevel were marked and then roughed out on the table saw ...

The table saw is a slider, and the rip fence was used to position spacers, before clamping a panel for cutting the bevel.

The bevel was then finished with a hand plane ...

This Jarrah is particularly interlocked but planes well with both a high cutting angle (the little HNT Gordon palm smoother) and a close set chipbreaker (the Veritas Custom #4).

Once the bevels were completed, the rear rebate was ploughed ...

Now the panels could be assembled into a case once again, and the work examined for tuning.

Three of the bevels needed tuning. This ranged from a smidgeon here ...

... to a largish amount ...

The case was dissembled and the bevelled edged planed down, re-assembled, checked, pulled apart again, planed ...

The rebates at the rear turned out to not require any tuning, with the exception of one corner ...

... where I had obviously forgotten to plane! :\

That was easily rectified ( ... but the case had to be dissembled again). Finally, this is the rear of the case and the completed rebates ...

This is a rebated corner ...

Here are the front bevelled corners ...

This illustrates by the mitres on the corners of the dovetailed case needed to be perfect. Any undercutting would show here.

Next, the drawer dividers need to be done. I'll mention here - since I would appreciate the thoughts of others - that this area has been my biggest headache.

The reason is that my niece would like the drawers to have the appearance of a single board. However, to achieve this, because of the bevels, is quite complicated.

First of all, the table cannot have just two drawers. The width of the drawers will be greater than their depth, and this would likely lead to racking. Consequently, I plan to build three drawers, which will be more favourable for the width vs depth ratio..

Secondly, if the drawers have dividers between them, which they need (since I do not do runners), then there will be a gap between the drawer fronts (which will not flow uninterrupted).

As I see it, there are two choices: the first is to build the drawers with planted fronts. This is not a method I like (but it may be expedient). The second option is to set the dovetailed drawers sides back (recess them) to account for the internal drawer dividers.

Thoughts?

Derek, I don't know what a Since board is. Can you elaborate, please, I'm enjoying following this, even though it is way above my pay grade

 

[Derek Cohen (Perth Oz)]

Steve, I don't know what a "since board" is either ... must be a typo. Where did you see this?

And I very much doubt any of this is beyond your excellent skills.
