I have a general question about crown molding. I have tried to study all the ins and outs of all trim work. The best ways to do things and have been doing trim work for some time now, but I have never had someone explain to me WHY crown molding has to be cut upside down on the miter saw. I know that it will not work the other way, but like I said i have never had anyone explain to me the WHY. I have asked other carpenters why you do this and all I have ever got for an answer is “well that is the way you just do it“. Most of the carpenters that I work around could care less about the whys of carpentry and they just do it. I like to understand the whys to better help me complete any job or task that I am doing. I totally understand that different crown moldings have different spring angles. Most crown that i install has a 38/52 spring angle. What if you had crown molding with a spring angle of 45/45 degrees, would you be able to cut that molding either way, it would seem like you should be? I was watching a video on installing crown on vaulted ceilings and I did not know that when you cut the crown going up the rake side of the room that you do not cut the crown upside down in position but rightside up, don’t understand. Can anyone offer some insite on this subject. Thanks
