I'm trying to imagine the octagon shape around your fireplace, but I cant!! Are you saying it bows out with eight equal sections ? If so it can't be a complete octagon, so 8 x 45° angles (16 x 22.5° cuts) will not be any good? How many sections are there? and how do they relate to the main wall? You may be better to measure the angle with a TREND angle divider and transfer half the angle to your cutting jig. Most tool shops should have this or will get it for you.

Buy a precision mitre saw - the type that has angles from 0 - 90 and back to 0 marked by the blade. Measure the angle you want to cut and away you go. They are not expensive - around 10 pounds from B&Q. I used one for skirtings and covings with great results. Cut my finger once or twice and my thumb three times, but that is DIY for you. Have fun!

from the centre of each corner / angle hold out a straight edge this should give you an even angle each side of the staight edge you can either use a protractor to measure the angle or use the straight edge to mark your coving ,so long as both angles/ mitres are the same you should get an even corner joint ,also you'll find that if all else fails the adhesive makes a great filler which you can sand down and you'll never see it when it's painted ,good luck.

To match each piece (8pieces) and look like an octagon, try 22 1/2 degrees for each piece. That would be 16 cuts at 22 1/2 degrees.

Go get yourself an electric compound mitre saw...(I recommend DeWalt 12 inch).
Now, get yourself a bevel or locking indicator for wood. (basically two pieces of metal, that when you turn the wing nut, will hold it into place. You put the bevel on both edges of the octogon and lock the nut, then, you have your angle). Transfer it to the blade of the mitre saw and cut away...
Easiest way I ever found to do angles, and I did a whole room with slanted boards and they turned out beautiful!
I wish you well..

its all in the angles:
the whole room is 360 degrees & you want to divide it into 8 pieces that all fit together?
try 360/8 ~= 45 degrees (i.e. half a square)
get a small piece of coving and try it out first!

You can buy a coving cutting template from DIY stores. I bought one myself when i did mine. It has different angles on it purposely for your problem.

Since you will be filling the joint anyway the accuracy is not too important as long as you are talking about coving and not cornice.
