Re: Crown molding coping question
another thing to consider is if the first peice thats already on the wall is laying at the correct angle on the wall.. meaning is it actually sitting at 45 degrees.. having it off by a degree or two can throw off your mitre cuts angle. check the lay of the crown by nesting a piece of it in a framing square.. when its hitting on the same measurement both on the blade and tongue of the square make a gauge block thats the same dimension..now use it to make small ticks on the wall and ceiling every 16"-24" or so. use the marks as a guideline to keep the crown laying correctly.
another to do is dont nail the last 2' of the first peice of crown.. just let it float.. you can manipulate it and the coped peice until they joint up just perfect.. use thin shims as required to make the joint nice and tight by shimming where the crown hits the wall or ceiling.. dap it to hide any small gaps where it meets the ceiling or wall
fire up the saw and make some dust
