This started out as an experiment to use up a bunch of scrap OSB that had been cluttering up the shop for quite a while. The top and the lower shelf are made of OSB strips glued up butcher block style. Prior to gluing I ran each strip through the drum sander to get each side flat, as the back side of the OSB is dimpled, and the front has a finish on it and is far from flat. This uses a lot of glue, but it was a good opportunity to use up all the old glue I had in the shop. After the glue set up I ran the whole thing through the drum sander to flatten the whole thing. I can’t imagine doing this project without a drum sander. At this point the wife decided she liked the look of the top and she wanted it to be a table to feed her cats on (so the dog can’t get the cat food). Initially I thought it’d be a table for my mini lathe. I filled small voids in the top with glue mixed with sanding dust. This was a mistake as those areas didn’t absorb the finish in the same way the rest of the top did. The bottom is made of 3/4 and 5/8 inch Home Depot OSB with the red edge paint. The top is made of 1/2 inch OSB with the green edge paint. I’ve been told that the green paint indicates higher quality OSB. Whether or not that’s true, the 1/2 inch OSB produced a much lighter colored product. I finished these with System Three’s MirrorCoat. I hoped one coat of this would be enough, but I made a mistake. I didn’t put any kind of sealer on the OSB so the epoxy soaked into the wood unevenly and left dry spots. So I had to apply a second coat. It looks really nice except for the gnats that flew into it.

The frame structure is made of pine that I salvaged from an old deck I tore down. It’s just basic mortise and tenon construction, nothing fancy. I filled nail holes and cracks with Bondo and painted it with regular latex paint shot with and HVLP. The wife picked the color. Opinions are mixed on that subject.

That is surprisingly freaking sweet!

Sounds like a lot of work but nice job!! (I maybe agree with the mixed opinions on the color though)

Very cool! Who would have guessed? My OSB all has blue painted edges. Never saw red or green.

Very cool! I’d try it, but I don’t own a drum sander. :-) I really like how the “grain” on the OSB turned out. You probably have a few pounds of glue invested in that thing.

Thanks guys. I honestly didn’t expect it to turn out as well as it did considering it’s all just a bunch of scrap.

It has a cool look! Any idea is worth to try, sometimes you end up with a great result like this.

You have figured it out well. The wood, color and design are awesome. You must be really
happy with the result.

Very nice. I believe I will have to try this.
The only change I will make is to band the whole thing in a solid piece of wood. That way people may be stumped as to what the top is made out of. I wouldn’t have guessed correctly until I saw picture #4 and realized it was OSB turned on its side.

Thanks again folks.

Ohwoodeye, I thought about wraping the outside as well. Without the sides the wood has an exotic look to it. I might do that next time.

Have your say...
