Topic tags/keywords: workbench building

Got a question. I found some 4”x4”x8’ pieces of lumber from where I work. I thought it would made a great frame for workbench. They came from a frame of a box that held 10 ton machine, so I figured it would hold up a workbench.

The question is could I use lets say 3, 1”x8”x8’ pieces of lumber placed side by side for the workbench top. Would it warp or bow. I don’t have a whole lot of money so I’m trying to do this as cheap as possible.

Any advice would be nice.

maybe, maybe not. I think it would be ok if properly attached to adequate framing.

My thoughts are that that’d be O.K. for a light-duty bench with, as Mics_54 said, adequate framing.

You may be happier with watching craigslist (free section) in Indianapolis and find a solid door or something like what was listed in Minneapolis yesterday; “18 – 4×8 sheets of MDF” and laminate a couple pieces.

Absolutely. But I would also add some 2×4 support underneath.

I agree with Charlie to add some 2×4 supports underneath for cross bracing.

Why not just use 2×4s for the top also. Stronger and cheaper than 1×8s. Where I live, pine 1×8s from the borg probably cost about $6-8. 2×4s are under $2 each. Try to find kiln dried so they won’t leak sap. In California they mix Douglas Fir (DF) and Hemlock Fir (HF) depending on the supplier that day. The price is the same, but DF is a lot stronger.

I made mine from this plan and it works great. (Cheap too.)

I don’t think you would be happy with a 1x top. My old workbench had that and things would bounce off the top from vibration.
