I need to create a perfectly flat surface. I am using a router and attempting to engrave in wood 0.05” deep. What I have noticed is that my block sanding efforts, unfortunately do not always yield a perfectly flat surface. I’m considering a sand-flee, a drum sander, or maybe a planar to get the flat surface need, or is there something else I should be using. Your advice is most appreciated.

A planer smooths, thins, and duplicates the opposite face….it does not inherently flatten boards without the help of a planer sled, but a jointer definitely will!

It will depend on the size of the surface. How big is it?

A “sanding board” is very useful, and very cheap to make, for
making wood surfaces very, very flat.

I cant remember which episode of the Wood Whisperer but he made a router jig for flattening out very large pieces.

I usually start with a 6 or 8 inch wide board, so a planer would work. The joiner idea is one I keep coming back to, but I just don’t understand how they work. It seems to me that running it through the joiner would take the same amount of surface off of the board for the entire length, and it still wouldn’t flat, just thinner. I am obviously missing something.

Works the same as a handplane. A jointer takes off the high spots. Take them
all off and it will, in a perfect world, cut your board uniformly flat.

In our imperfect world however, operating a jointer and milling extremely
flat and straight boards requires considerable operator skill. It’s much
easier if the boards are 24” or less. Accurately flattening 8 foot boards
on a jointer requires skill and insight with the tool.

Becikeja, with the jointer, the infeed side of the jointer is slightly lower than the outfeed side. When you feed the board into the blade it takes a smidge off. When you get enough of the workpiece past the blade you keep your pressure on the outfeed side of jointer just past the blades. This method is what makes a perfect flat board.
