OSB Pie-Slice Table

Some years ago, my wife and I were going through an “open studio” tour in our area. One artist had done the floor of her studio in OSB and had it semi-finished. That way, she had the warmth of wood, but didn’t have to worry if she accidentally spilled paint or something on it. It was beautiful!

So I started playing with OSB – sanding it, filling it, planing it, varnishing it, etc. and found that you can get some very nice depth to the finish by treating it right.

Since the edges are the least pretty aspect of OSB, I trimmed those with thin veneers cut from 2X4’s, and then putty, sand and varnish the whole thing.

The original purpose of this table-top was to show that you could build a table with an 8 foot diameter (4’ radius) out of sections that could go through my 1-foot-wide Delta thickness planer. A little math shows that you would need 16 such pieces. So I made an experimental one 2 feet across roughly, and my wife asked me to turn it into a real table – There has been no stopping me.

On top of it – since most 2X4’s are new growth lumber, and OSB is essentially scrap material, it’s environmentally responsible, and reasonably priced – especially good for projects that are going to be subjected to the tender mercies of kids.

Very neat use of OSB. Great job.

Love the table. We should be neighbors. I too use deminsion lumber (Pine) and sheets of plywood, some exterior, some construction grade. All the cabinets that I built for my shop were built with construction grade plywood. If I screw up, It don’t cost me a whole bunch to scrap it and start over. I’ll have to try the OSB. I’ve got plenty laying around. In fact I just built two wing shelves onto my table saw from OSB that attach to the base of the saw to put push sticks, miter gauge, etc… on. I’ll have to take some pics and post ‘em when it gets warm enough to go out to my shop. Haha.

As you can see in the pictures of my shop, OSB are the interior walls of the shop. I was able to get a real good price on a pallet of 1/2” OSB. I still have a few sheets left.

Bob – Very well executed. It looks pretty darn good. Did you actually run the OSB through the planer? I would have assumed it would have had a lot of chip out.

Pretty cool interpretation for material that is associated with construction grade projects.

It look nice but I’ll bet that thing is heavy.

Thanks alll! That was just my first OSB project – I’ve done many more – with some still in progress. My wife loves the appearance. I recall many years ago when OSB was first coming out, I could find it sometimes for less than $3.00 per sheet – no more of that though.

To address comments/questions:
- There is a modest amount of tear-out, but not much. OSB is apparently made with a pretty good glue/resin binder.
- The table doesn’t weigh all that much – maybe 10 lbs on a guess (not hauling it up to stand on the bathroom scale with though)

Heading down to Pasadena, CA for the Rose Parade – I’ll post more stuff after the new year.
