Hi guys.

First time posting in the cave.

I'm making an armoire and the side rails for the upper portion are 64" tall. The method of attachment to the 1/4" plywood panels is called stub and groove or something.

I ran my 3/4" stock thru my table saw to create this groove. However, one of these boards had a slight bend over the length of it. It was impossible for me to hold it tight against the fence and I ended up creating a very wide groove in the middle. You might be able to see this in the top of the photo.

I was thinking the only way to avoid this in the future is with hand tools. But I'm thinking is it even possibly (while maintaining sanity) to make a 1/4" wide 3/8" channel along the length of a 64" piece of wood with hand tools?

The first picture shows one complete middle side of the armoire. The second is what I was talking about making the second side.
