[ATM] plywood question

[aart at insightbb.com (Aart Olsen)]

For warped wood, instead of a table saw dado I'd use a router.  A table 
saw depends on the wood being at a uniform depth over a large area, and 
a big warp can introduce an error that's greater than the thickness of 
the wood.  A router only needs the thickness to be uniform over a small 
area, so warping doesn't matter too much.

Use a large square when you're clamping and gluing joints.  I usually 
clamp the square to the structure with big spring clamps, adjust the 
pieces until there are no gaps under the square, and leave it there 
until the glue sets.
