   *Don--Used those Delta charts more times than I can remember. They work great for standard angle crown mouldings. If you've purchased your crown from a stock profile, chances are those tables will work.If, however, you're using anything other than a 45 or 37 degree crown, the following formula can be helpful. You can also find it in the July '91 article:M=arctan(A/(Cx tan (F/2))B=arcsin ((D x cos (F/2)/C)M=miter angle settingB=bevel angle settingF=corner angle of wall (usually 90 degrees)A=distance along ceiling from the wall to the back side of the moulding where it intersects wallD=distance along wall from ceiling to the mouldingC=length along flat back side of the moulding.Therefore, A,D,&C form a right triangle, and the angle the moulding makes with the wall is arctan (A/D).Formulas won't always get you 100% the first time, due to misaligned saws (how good is the scale on your radial?) crppled walls, but you can usually get close enough so its perfect with just a minor tweak.Another option is to buy one of those fancy Bosch (?) protractors that do everything but pull the trigger on the saw for you.Happy trimming.

   Thank you all, managed the inside and outside corners OK, with a little caulk and paint they'll look fine.

   b ARRGH!!!!!!!!!

   Cope crown molding. COPE IT!!!!. However, to cut the molding at the right angle, set the board on the saw as it sits on the wall. I usually clamp a board on the saw to make sure that it stays in the right plane. Simple! No angles to calculate whatsoever.

   *Don:Use the Breaktime b Search function. This is an FAQ and has been discussed in length several times.

   *Don, Get yourself a chopbox, set the crown against the fence to make a triangle (inverted from how it would appear on the wall) and simply cut a 45 degree miter.Dave

   *Thats the way I've always done it. (With the occasional cope saw solution for irregular walls/corners) I have found it very surprizing how many people are unable to visualize the cut upside down tho. Not an indicator of intelligence, rather an indicator of right brain/left brain function and communication.

   I'm a weekended having a tough time installing crown molding around outside corners in my basement re-room. 45 bevel I 45 miter on my radial arm doesn't seem to provide the right results. How do I compute the settings.
