what angles do you use on a compound miter saw to do an octagonal room?

Answer 1

cut a 22.5 degree angle and butt it up to a 25degree angle. it should work.

Answer 2

Assuming you are talking about installing baseboards, this is the same as installing to a square room except using half the angles. In other words, 22.5 degrees.

Usually coping the joint gives a better result. If you want to do that, read a basic DIY book and modify the directions to use the 22.5 degree angle. In a nutshell, you will install one baseboard butted flat to the wall using a reverse 22.5 angle. Then cut the next board at 22.5 degrees and use a coping saw to remove the end, flushing to the cut line.

Answer 3

45 degrees for 4 walls. 22 1/2 degrees for 8 walls. 11 1/4 degrees for 16 walls, and so on and so on.

Answer 4

22.5, ignore the answer from flstc88. That would give you angles for a 16 sided room

Answer 5

I would use a stiff piece of paper and fold it to fit into the place
that you want to splice lay it on your wood and mark it with a pencil and just cut it by hand.

Answer 6

you would use a fourty five degree angle.. a four sided object has four ninty degree angles so an eight sided object should be 8 fourty five degee angles..

Answer 7
