Do you know what “flush” means in carpentry?

It’s not the same thing as in plumbing, that’s for sure. It means that two surfaces are in line; that a board placed against those boards would be perpendicular, not slanted.  It is important in construction that corners actually be flush, plumb and square.  Don’t know what those terms mean either? You’re not alone.  That’s part of NCSC’s Hearth wants to do, help people become familiar with these terms and how to use them.

BTW, plumb means perpendicular to the ground and square means all angles are 90 degrees. This is vital to the strength of any construction. Geometry in action. See the value of this type of instruction?  Please support  us at http://www. so that we can get our Hearth built, square and plumb!
