Planing and Scraping Plywood?!?!?!?

Christopher Fitch @ Memphis

>Hey all,

in my seemingly never-ending odyssey to finish my bench top, I resorted to extreme measures.

Some background:

I build my bench over the past 6 months or so. The base and drawer cabinet have been completed for some time now. The top has been close but not quite done.

This is the second bench I have built so I have some experience with what is important, as least to me. One of those things is having a relatively flat top. My first bench was made out of SYP and had as many waves in it as a lake on a windy day. So I developed a probably unhealthy paranoia for having a flat top on my next bench.

So I decided to make a new one and I followed Christopher Schwarz' recipe for making a top by gluing together 4 pieces of 3/4" baltic birch and framing it with an apron. It went together well enough and it was mostly flat except for a dip here and there. However, the worst part is the one corner that is lower than the rest of the top by about 1/16".

So, having attempted to plane plywood once before with little success, I decided to pull out the dreaded dust-maker, my PC 333VS ROS, and sand the top to mostly flat. Well, I have been sanding for some time. I learned alot about sandpaper, how well my dust mask works (very good), and how dust gets everywhere, especially on the furniture after you come in from a nice sanding session.

Well, a few months and many sheets of sandpaper later, I'm closer, but the dip in the corner is still too much for my comfort. So last night I decided to try my new LV scraping plane.

Whipped it out, cleaned the blades (I bought the hard one), put on a burr, and scraped away. The plane worked like a dream, but it was even slower than the sander. So I was still no closer to having my top flat, so I decided to try planing.

This time though, I decided to use my #4 1/2 and just deal with the tear-out. It was better but still not good enough. If I set the blade to a bigger cut, I could get it but I would also lose some chunks of the top veneer. But I am closer, so I think one more good sanding session tonight might get me close enough. And then I can put a finish on the sucker and move on!

On a side note, if anyone wants practice dealing with stubborn or reversing grain, plane or scrape some plywood.

Thanks for following along with my odyssey!

>Belt sanders really hog off the plywood. Your only problem will be avoiding crunching through the layers, when you'll hit glue, which will cut up your sandpaper. Have you considered turning over the top? Seeing a shrink? :)

PS Belt sanders also hog off regular wood

or shimming the corner?

>Can't shim it... I thought about that.

It's out a distance from the nearest base leg. I shim that corner, then the rest of the top in that area goes higher and I end up with a hill.

>heh...

I'm trying to avoid buying a belt sander. I don't need another dust monster in my shop...
