So, we got tired of a cookie cutter, nice, coffee table. At the same time were given an interior door from my wifes great-grandmothers(Maw-Maw Walker house.
I looked on the line for ideas.
OMG!!! It's been done a billion times over...Can I put my own spin on it?
I started looking on instructables and saw a coffee table that is based on geometry:
I piddled with this a little when I was little and could remember folding up some funky stuff. Later on in the Google age. I liked trying to do some geometric origami. Tessellations. Google that.
Yep pretty awesome!!!
This is my What & Why...The rest is the How
Step 1: Can I Make a Small Scale?
I figured that I have one door and one chance. So to make sure that I don't screw my door up, I made a mock up. And I am glad that I did.
The door started out 80"x30". My finish table top will be 24"x48". To get the ends to be right, I had to cut the middle six out. I did not realize this until my mock up.
I labelled all of them from the bottom up. Started with L1&R1. The Angles that I used is 13degrees.
It just looked right. I couldn't find my pics. But I mocked up a 2x4 12, 13,14, degrees. I thought they all looked the same. So I chose 13 because it sounded cool. Plus, I went to get a tattoo, yeah, gettin' ink done. Asked for a 13 but they drew a 31!!!!
The flip flopping of angles was hard to do. It was a lot of turning around on a chop saw. I started out with eight feet by four feet of three/quarter plywood. It was not enough. Between the missed cuts and "dangit" wrong angles. I ended up using about sixteen feet.
Step 2: Cutting Up the Door!
The things I used most was a Compound Mitre saw and a table saw.
Start off with the table. I wanted to save as much as possible in case I needed some uh'oh material. I ran it on the cross cut down to thirty(wide)x48(tall). Making sure to keep the mortise for the knob.
The know would be a big selling point to keeping the door theme.
Next, Split it down the middle. then I had two pieces 15x48.
Now to the Chop saw?
Being 12" square, the hypotenuse is longer than my chop saw. This makes my cutting a little more precarious.
Either way, I stick to the plan. I use my mock to check all my angles. No room for missed cuts. If each panel is to line up. No pressure????
Whatever!! It worked.
Step 3: Biscuits, NO Gravy?
Joinery and Glue.
The first pic is my biscuit jig. It keeps allof the angles and facing lined up.
I always thought the cutting of the door would be the hard part.
The second pic are the boards with 13 degree angles cut on them. This will serve to mount and screw the door up while the glue hardens. Clamp jigs that I made up sucked!!!
The best thing was to line up the left and right first. then glue up to the big mast.
There was a few gaps and offsets along the way. Nothing that a little wood glue and saw dust couldn't fix.
another thing that was part of the original concept is; we wanted a rough patina. Learned that from Lara Spencer on Flea Market Flip.
Step 4: Making the Table
The Table needs to be topped out at 19 inches. the door is 3 inches in girth. This gives a rough table of sixteen by 48 ish. It also had to have a bottom shelf.
I won't bore you thru all the details. The top part is made of white pine. The legs are doubled yellow pine one by four on a 13 degree angle. I thought this would accentuate the top a little. The shelf is yellow pine also with plywood in the middle.
The hard part of this was getting the apron to fit tight under the crooked part. The best jig I could come up with was a two inch offset marking scribe. This set off all the angles. Then I cut on a bandsaw at a thirteen degree angle all the way. It didn't hve to be, but it can't be seen and makes it all tight with no problems.
Step 5: Sand and Paint
Before I could sand I backed out all of the screws. Filled with a wood putty made from titebond glue and saw dust.
I used a random orbital Ryobi and a mouse sander for the corners. 80,120,220 grit.
The trick of the matter is to sand smooth but leave some bumps and imperfections. To purposely leave these imperfections is a little disheartening.
I then sprayed the table, and brushed the top.
Step 6: More Glory Shots!!
Hey! It took me two months. Let me show off my hard work. Thanks for looking, and sharing, if you did.
Step 7: Kick Back
Kick Back, Chill, and vote for me in the laser contest.
Step 8: Write an Instructable
This part is fun. Go thru all the pictures and just think about the whole process.
When I was thinking of the title, I just hit the wall. All I could really come up with was lame pun ideas. Or non exciting titles.
Another old door coffee table?
So I shot a message to a very respected, creative, helpful member for help.
He came up with this crazy title and I love it! So, big thanks to him and the whole instructable community for such a great site.
Is this a tessellation?
A lot of discussion on the comments suggest it isn't. Here is websters definition:
a covering of an infinite geometric plane without gaps or overlaps by congruent plane figures of one type or a few types
Math is fun:
A pattern made of identical shapes:
• the shapes must fit together without any gaps
• the shapes should not overlap
The table has six exact same trapezoids with contrasting side angles.
And four halves of the same trapezoid. Confused? A Tessellation? Seems like it to me.
Also, is it an optical illusion? I took a lot of pics of the table. I intentionally used the ones in this ible that distinctly showed all of the shape and angles.
