I need to put trim down in my bathroom The rear wall comes down, makes a 45, goes a little bit and makes a 45 and then does the same thing on the other side Basically it looks like an angular U Since it was 45 degrees, I thought that a 22.5 degree cut on both pieces would miter up well. Well, its not even close. Short of trial and erro, is there an easy way to get close on approximating angels so I dont waste a ton of baseboard Thanks |

As above, use scrap to get it right and then cut good stock. I don't waste alot of time on it. I get it close and caulk it. I will not do the trim in the house we are building. It's expensive to have done, but it's an earned skill. Trim is hard to do and I've worked on very few square walls. I cut near perfect left/right and in/out angles to keep and use them to set my miter when I work. All the "upside down and backward" cutting gives me a head ache. |

Go to your local big box home center and buy an angle finder. It's like a protractor and has a few different scales on it for measuring inside and outside corners. Whatever the angle of the wall is to the other wall , split it n half to get your miter. You can use a T-bevel too , but they do not have measurements on them. You can use the scale on your miter saw to measure what the t-bevel measures , then split that angle in half to get your miter. Hope this helps. |

If the angles are all f'ed up, you can break down and get a digital protractor that tells you what angles to cut the pieces at. Alternatively, get a section of cheap fiber baseboard at Home Depot and get the angles down before you cut it on your good piece of trim. Caulk is definitely your friend. |
I just discovered last weekend how great caulk works for fixing cracks in trim. The only trim that will be painted in my cabin is in a closet, but I caulked ALL the joints and they simply cease to exist once it's painted. Amazing! That's a trick I learned here, BTW.  *Please don't berate me for trimming the inside of a closet--I'm obsessive about such things.  **You don't want to know how much time I spent getting the drywall mud "just right."

Cut as close as you can for an inside miter, then use a coping saw to remove the excess. The line of the miter edge to the face of the trim is the cope line. |
