Japanese style walnut slab coffee table
« on: August 02, 2020, 11:01 AM »
Recently FOG member @rmhinden posted pictures of some bonsai stands that he made.  I really liked how they came out so I decided to cop the design for a coffee table I was making



The one design modification is the angled front support (done at 11 degrees), a detail which I saw in a similarly styled table later on.

Got the slab from Boards and Beams in NJ



Had to sort through a bunch before finding this one -- most were either too wide or too long, and since I only planned on doing this table at the moment, I didn't want to have too large of an offcut lying around.  It's a bit in excess of 7 ft. in length, and 21" at it's widest.

I ended up with about a 3' offcut, which I'll use at some point in the future for an even smaller table



Surfaced the slab with the Woodpeckers slabbing mill, then stabilized the crack with wenge butterfly inlays, cut out and mortised with the Shaper Origin





The Makita brush sander did its thing cleaning the live edge via the nylon wheel without excessive degradation to the softer wood


'


For the base, made from 8/4 walnut, I fortunately had all the wood on hand in my shop leftover from previous projects.  The only downside was that one of the boards had a substantial amount of the whiter sapwood along the edges, so I concentrated that along the center line of the larger leg when edge joining the boards, and faced it to the outside of the table for less visibility





Base is put together with bridle joints made on both the table saw (w/dado stack) and router table

Base attaches to the top with 14mm dominoes, and then screws through the perpendicular collars on the two supports.  I aligned the dominoes by securing stops to mark the position of the base on the underside, then added 5mm wooden shims to compensate for the 15mm offset of the domino centerline from the XL base (supports had been mortised at 20mm using the preset height on the machine)







All the mortises were done at the wider setting to facilitate the fitting.

Routed the bottom stretcher about 1/16" everywhere except a;long the bridle joints so that it floated slightly above the floor and didn't affect the stability of the table



Had to spend a bit of time preparing the glue up.  Used a pair of 48" and 24" bowclamps to target the clamping pressure.



Finished off with some Osmo matte

Wow, that is very nice!

One question, how did you allow for wood movement between the top and the base?

@ear3   Another nice build!  Looks great!

In general, I'm not a big fan of butterflies, but I have to say that the shape, with the curve (as well as the choice of wood/grain), really makes yours stand above the rest.

Thank you for sharing and posting so many photos!

Thanks!

@rmhinden I slightly slotted the scrfews and left the middle tenon on the perpendicular support floating.  I figured that was enough for a piece this narrow, but I guess we'll find out?  It's a piece of home furniture rather than a commission, so I suppose I can troubleshoot if something goes awry.

@Michael Kellough  No trailer unfortunately -- see you on the other side of the vaccine I guess?

That’s really nice. Helps me a lot to think about how to use some nice slabs I brought to San Diego from Maui: two long pieces of chocolate albezia, and a big slab of mango that will make a great table. When the time comes I will solicit advice on how to flatten the cupped albezia.
No hurry now because we have a two-year-old granddaughter and another on the way soon, and live edges are not exactly kid-friendly. Contrarily, kids are not exactly live-edge friendly.
I will bookmark your post for future reference

I wanted to mention that I got the idea for the Bonsai stands I made from:

Bonsai Mirai

The web site says they were built by Jason Eider.  Just found his web site.  Lots of nice work.

Edward I really like the bridle joints. Good job. Did you have to do a lot of sneaking up on the fit or did you come up with a good way to hit it off the bat?

Thanks for the reference @rmhinden

@rvieceli I got it pretty close with the table saw using digital calipers to monitor depth of cut (did the legs first, and then the crosspiece second).  Was able to do the finish work with just a paring chisel to take off last few thousandths to get a perfect fit.  For the angled joint, I obviously had to chisel off the ends of the notch to match the angle.  Then used a jointer plane to even out the crosspiece relative to the bottoms of the legs.

Mixed in a little blood with the wood in the process:

More wood art...great stuff.  I've worked in glass industry for the last 40 years (among other things), told an ER nurse after slicing my forearm 14 stiches worth that I felt that it was good to bleed on a regular basis so my body would know what to do in a serious accident...she didn't think much of my theory, but isn't that how the body develops disease resistance, she still was not convinced.  Maybe not but I have tons of scars and at 67 still rapidly.

 [thumbs up] Nice job Edward...the 11º angle makes all the difference.  [big grin]

Never really been a fan of bowties/butterflies but those were really executed nicely. Again, the continuous curve makes the difference. How did you finish off the pockets? Maybe an 1/8" diameter router bit and then a sharp knife for the corners?

Yeah, angle definitely helps.

Correct, initial pocket with a 1/4 bit, then finishing inside cut with an 1/8 bit, then just chiseled out the corners.  I didn't think of using a knife, but I see now that might have been effective too.  Found that I could have really used a fishtail or skew chisel for that work, which I don't have, but which going forward I guess I will have to remedy.  EDIT: Lol, speaking of which, I was looking at the bluespruce skew and dovetail chisels -- yesterday they were set to ship in late September, this morning I checked again and they are now set for late October shipping.  Guess I should act soon.

Thanks  @six-point socket II ! I had considered doing an even steeper angle -- maybe 13-15 degrees -- but I was worried about deflection from the downward clamping pressure during the glue-up.  11 degrees was the steepest I could get where there was an imaginary perpendicular line that still intersected a portion of the top and bottom edges of the support.  The bridle joint ended up being pretty tight and effective though, and I probably could have gotten away with a few more degrees in the end.  But by the time I realized this I had already cut the joint and could not change it. 

Looks great, love the bow ties & 90 degree turned and angled foot.

Kind regards,
Oliver

So for the final cut with the 1/8" cutter, did you take any additional material away or was it just run around the periphery to clean up the 4 corners? Gotta know these things so I can finally get my Shaper up & running. [big grin]

@Cheese If I understand you correctly, you just mean the settings on the final inside cut?  (please forgive me if I go on to explain something you already know)  There was no offset on that final cut, but just set to cut right up to the line -- machine calculates what to do once it gets into acute corners like that so that it doesn't move outside the cutting area, so there ended up being more hand work to do to square off the corners than there would have been if they were 90 degrees.

The nice thing about the Shaper is that on the pocketing cut, it stays well away from the perimeter of the cutting field, because it assumes that you will take a final finishing inside cut to get up right to the edge.  Except the first few times I did this sort of cutting I did not realize that and attempted to do everything with just the pocketing cut (rtfm, right?), and so I would adjust the offset so that it did cut up right to the line in the pocket setting.  The line was predictably ragged in a few spots.

Thanks @ear3 for that info...interesting to know the amount of machine intelligence that's incorporated in the Shaper.  [cool]

But those corners and the shape of the butterfly is soooooooooooo much nicer than a simple 90º corner. [thumbs up]

True story, when I did this countertop about 2 years ago I was going to place a couple of "your style" Ebony butterflies in the gap on the LH side. However, lacking a Shaper and the tooling/fixturing I needed, I just decided to move on without them. I tried to keep the task as a home improvement project and not turn it into a science project.  [smile]  I also didn't want to hack up and destroy a 200 year old chunk of white oak. If I had the Shaper back then it'd probably have been a different story.
