    You can’t trust the factory edge of plywood to be straight or the corners to be square. It varies from one type to another but in my experience most types can have curved edges and out of square corners on at least some of the pieces. I recommend verifying the straightness/squareness with tools that are known to be straight/square before using it for any project where accuracy is critical.

    In my own work I make it a habit to straighten one edge with a track saw and then square it with a panel saw and work off those sides/corners for the rest of the sheet.

      Plywood edges are usually pretty straight because the perpendicular grains of the ply basically removes horizontal stretching of the wood so it won’t warp and therefore will retain the straight edge cut by the factory.

    the link to the toggle clamp is for a horizontal one. this won’t work as it interferes with the fence. make sure you get the vertical ones (which are actually shown in the video).

      Thanks for suggesting this tip. I almost was stuck with horizontals because I didn’t know the difference. These are available for close to the same price at HF.

      Thank you. i’ll probably find a use for the horizontal ones I ordered, but now I ordered a couple of vertical ones too. Glad you alerted me before i tried to figure out what I needed when I couldn’t get the horizontal ones to work! 🙂

    I just made my own following your instructions. (Found the vertical toggle clamps at Harbor Freight.)
    Thank you!

    Not sure if my message went through. My question is how long is the edge joiner. Or does it matter.

    Just built mine, it’s literally drying as we speak. I’ve tried jointing on the router table but can never get it right and end up chomping all the wood away!
    A few questions about length. I made mine just a bit shorter than the regular fence. I’m likely to want to hold work pieces that are a deal longer than my fence so I figured go for the most stable I could handle.
