Exhaust clamps for lap joint 1.75?

measure twice - cut once! cut off wheel works like a hot knife through butter - be SURE to draw a guide line.. really easy to get off straight with something that cuts that fast. If you're doing butt joints you'll want to be right on the $$ with your cuts.. if going lap joints you'll have a little "wiggle" room but still will want to get it as close to tight to each butt as possible.. make sense?
