I'm going to make an octagon around a round column using crown moulding and want to know how to determine the angle to use on the mitre box. Let's just say for this example the column is 12" round.
I can somewhat figure out that it is probably half of a 45degree angle used for 90degree inside/outside mitres on 90degree walls, and making the same angled mitred cuts on both ends should get me the results i'm looking for.
Q#2: If it was previously done and one section needed to be replaced how are the mitres degrees,angles determined for the piece being replaced.
Is their a tool that will give me the angle?
360 degrees in a circle divided by 8 for your octagon is a 45 degree angle divided by 2 for your mitre cut is 22.5" on your saw. doesn't matter if its a 2" circle or a 22" circle. you just need to determine the length of your parts. I suggest drawing it out on paper first so your not cutting up your wood figuring it out

A common problem for first timers is laying the crown molding flat on its back when making the cut. This requires a compound angle saw and multiple angles.
Lay the crown molding against the saw fence at the same angle as it sets on the wall (or column). Clamp a strip of wood to the table to maintain that angle. When working with crown molding you must pretend that the saw fence is the wall and the table is the ceiling. The 22.5 degree cut is made without tilting the blade.
