I was researching different ideas for a deck in my back yard and found some interesting decking patterns on the internet, then stumbled across this video about the ancient japanese finishing technique call Shou Sugi Ban, which involves burning and scrubbing the cedar wood to give it weather resistance, bug resistance, and strangely enough, fire resistance. The end effect leaves the wood with a metallic sheen that changes with the angle you view it at and is quite beautiful.
I realized it would be way too much work to do a whole deck this way, but it might be really cool as a coffee table. I then decided to basically make a coffee table using the same style as a diamond pattern deck, but scaled down.
The table is all cedar except for hidden support, and all wood is readily available at your local big box home improvement store. Total cost is a little over 50 dollars in wood, plus whatever tools you don't have.
I am a total amateur wood worker, which will be obvious when you look at my pictures, but the table receives a lot of compliments and if I can make it, so can you.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Materials List
1x4x8 cedar board 6.48 x 3= $19.44
3.5x6 cedar picket 1.48 x 8= $ 11.84
1x2x8 furring (white wood) 1.02 x 4 = $ 4.08
4x4 cedar post $ 8.00
tung oil (optional)$ 10.00
stain (optional) $ 7.00
Step 2: Tools
A 20 dollar propane torch from Harbor freight is the best way to make short work out of burning the wood. Be aware that the intense heat from this thing can set things on fire several feet away from the piece you're burning.
A compound miter saw makes it easy to do any pattern you want for the planking, and allows mitering the corners of the border pieces. A miter box and a hand saw would work, but you will need a lot more time and patience.
A pocket hole jig can make extremely strong joint connections if you have one, but glue works just fine.
A square helps in keeping the table aligned.
A nice flat build table and some long pipe clamps would have helped a lot, but I was able to make do without.
Step 3: Design
With just a few tweaks, this design can be as different as you want it. You can do your planking in a different style like parquet or herringbone, you can shou sugi ban the frame too instead of doing it in a contrasting stain like I did, and you can make it any size you wish.I decided on 32" x 60", just because that seemed to fit the area, and went with a contrasting merlot stain on the frame to match the wife's accent colors in the room.
You may have noticed in the video the step where the wood is oiled. I intended to do this, but after some experimentation found that the oil draws the ash out of the wood and keeps it in suspension, so that you get a black smudge on your fingers every time you touch it. Non-oiled wood handles cleanly. If you're planning on a glass top, the oil might be a nice touch, but it only makes a subtle difference in looks.
Step 4: Building the Frame
First I mitered the 32" and 60" pieces at 45 degrees.
I then found out that using pocket screws on mitered 1x4's is problematic, or at least beyond my skills. I wound up just using glue at the corners and using pocket screws on the divider pieces.
Step 5: Support Furring for Planking
Using a scrap piece of planking as a guide, install the 1x2 furring along the inside of the framing at a depth to make the planks flush with the top. I experimented here with screws, but titebond glue and clamps seemed to be the best way to get these attached.
Step 6: Cut Planking
This is what I would do different if I could start over. I cut the planks to size and got them all to fit tightly, but after going through the burning, scrubbing, washing and drying process, the planks shrank some, and afterwards the fit was loose with some gaps between boards.
I recommend you do shou sugi ban on all the planks before cutting them, so you can get a tighter fit than I did.
I started each section trying to cut a uniform first piece at the center, so all four sections would roughly match.
Step 7: The Fun Stuff, Playing With Fire!
Burning the wood is straightforward. My apologies for the focus on the video, I didn't realize it was that bad till I was finished.
Once again, exercise extreme caution using the torch. Dried out winter Bermuda grass will ignite a surprisingly long distance away from where you are working. (Yes, I speak from experience).
Keep an extinguisher and/or water hose close by.
Step 8: Scrub the Planking
Using a wire brush, wet and scrub the planks. The longer you scrub, the lighter the finish.
Step 9: Legs
I attached a square piece of planking in each corner for the legs to attach to and reinforced it with a mitered piece of furring as you can see in the second pic.
I then glued each leg in place with glue on the end and in-between the leg and the perimeter piece.
Lastly I added a couple of 2" decking screws down through the plank into the top of the leg.
Another option here would be hairpin legs, or galvanized pipe legs from the plumbing section of the home improvement store.
Step 10: Bringing It Home
I used a palm sander to round off the sharp top edge of the perimeter piece. If you have a router, a routed edge would look really nice.
Next I stained the trim according to the instructions on the can. Lay it on thick, wait a couple of minutes, then wipe it off using a lint free rag.
This was a lot of fun and I enjoyed making something I conceived in my own head. The possibilities for customization are endless.
I hope it has inspired you to try something new.
