    Sounds about right.

    Re: 90 degrees

    I’ve never found a need for corner clamps. I try to lay out on a flat surface or the MDF back to prevent twist then check diagonals. I’ve got a long bar clamp to shorten the long diagonal then measure the short diagonal until it’s between the short and long measurements.

    Re: 90 degrees

    I suspect a true 90.00 degree angle is the devil's angle and that nature naturally resists it when joining wood to prevent summoning the lumber demons or something. I don't know but everything I build ends up being ever so slightly out of square which ends up adding up to a few fractions of an inch somewhere on a long cabinet. Fortunately nobody really seems to notice but me. :( I've got a couple of those corner clamps too. I like the idea of that Wood Working Magazine jig tho. I might try to make a few of those!

    Interesting, I hadn't noticed that with mine. Then again I bought eight of them to glue up the whole box at one time, so yeah, YMMV.

    Very Pricey, but they work - Corner Clamp

    Or you can put 4 corner clamps on the top to keep everything square, and some bar clamps on the bottom to hold it together. Your choice.

    These corner clamps are pretty inexpensive, and can be found at your local hardware store: http://www.homedepot.com/p/Pony-3-in...66-K/100180604
    Bought some, didn't really like them, upgraded to these and never looked back.

    You can just buy the squares and use your existing clamps. The squares work.

    I always chuckle a bit in threads like this when the well intentioned advice is "build a jig". Basically telling someone who is having trouble with getting square corners to build a square jig.

    There are better corner clamps available. That was just an example.

    Re: 90 degrees

    Biscuit joints can help, but there is enough play in those that you still must check against a square object. I did biscuits on these and assembled each one in one operation save the missing side. I did screw up one joint on the backside of one cab by about 1/32". Didn't see it 'til the glue had set.

    You can scale them down to fit your needs

    A carpenter's square, combination square, or a square piece of wood used as a template while clamping works for me.

    You can route out a perfect 90 on a couple pieces of cutting board on a CNC table or mill and clamp it on both sides of the panel with a bar clamp. The routed area will keep the wood in place.
