Any way to flatten it ?

Thanks,

"underlayment lumber" What's that?

When I hear "lumber", I think of a board. (2x4, 2x8, 4x4, etc) When I hear
"underlayment" I think of sheetgoods, e.g. plywood (luan, perhaps), particle
board, maybe even MDF depending on the application.

What type of product are you asking about? What are you going to do with
it/why do you need to flatten it?

A piece of luan underlayment could be "flattened" by attaching it to
a frame made of "lumber". ;-)

I want to make a small shelf with it.

Underlayment is a plywood that is 1/8 inch thick.

1/8€� material seems too thin for a shelf that would be expected to hold much of anything.

Perhaps if you gave us some more details, we could offer something useful..

For now, I'll go back to my original thought. Make a frame and attach the plywood to
that. A 1/8" thick shelf is going to need a lot of support anyway.

I'll go with a frame made of 2x2 inch wood.

Shelf will support a DVR which weighs less than 5 lbs.

If wood was flat I could use simple shelf brackets.
