Hey everyone. I am new to woodworking and I am building a simple workbench with a base of 2×4s and a plywood top. I have the base built and the plywood laminated together ready to mount. However the top of the base isn’t perfectly flat. It consists of 4 2×4s making a rectangle plus a few more across. There are also the leg tops. What are some strategies for flattening the top? I was thinking a small orbital sander.

This is the workbench plan:

are you talking about the 4 legs are not even in length ?

if that is the case, without a lot of cutting, apply a skirt of
1×4 around the outside of the frame.
I think that if you turn the leg frame upside down on a true flat
surface then attach the skirt that will hold the leg frame true,
plumb, and square then attach the top. [does that make sense to you ?]
or ~ if the unevenness is not all that severe, you can use a host of
hand tools to make it true. . . . . with a little elbow grease.

Kind of hard to say, without pics and more detail, sanding could be easy or days of frustration depending on what needs to be fixed. I’m guessing you assembled it on a nonflat floor/garage? Are you using pocket screws for joinery? I’d probably take it all apart, get a sheet of 3/4 plywood or MDF and then assemble it upside down with the top resting on the plywood.

I wonder if he means the stretchers and frame underneath the top aren’t perfectly flat and so the plywood isn’t sitting perfectly flat on top?

That is exactly what I meant.

I never thought about assembling upside down. I think that would have worked. I’ll keep it in mind as an option for next time.

I ended up using an orbital palm sander. It’s not perfect but the top lays flatter on the base than before sanding. I used pocket screws to attach the top from the underside.

Since this was my first post it took a few days for the post to be reviewed and approved, so I ended up moving forward with the project before seeing these replies. Thank you to everyone who replied. I look forward to building up my skills and tools! This site looks awesome for keeping a build blog and sharing tips and projects with each other.
