mitering trim

[Harolyn]

I need help finding the correct angles for mitering trim on the edge of a piece of furniture that I am presently building. It has one outside corner that is larger 90 degrees it is somewhere around 120 degrees and then there is a inside corner almost the same. I do not have a compound miter saw at the present time. I have a nice table saw. Any help would be greatly appreciated. The trim seems to not meet it sticks out further on one side than the other when they go to meet. It is 1 1/2 wide and 3/4 thick oak that has been routered with a roman ogee bit for shape.

I'm not sure there is enough information to figure out what the problem is, but it sounds like something may be asymmetric (not square or not the same angles). If so, the only solution may be to just cut and fit. Make sure the saw blade is at 90 degrees - unless the trim or the edge is not square, you should not need a compound cut. Miter the trim at each end at an angle equal to one-half the angle of the edge. Do one end first, then "creep up" on the final length by cutting and fitting the other end until that piece of trim exactly matches the length of the edge. Then cut the matching end of the next trim piece without moving the miter gauge adjustment. Try it - if it does not fit then "creep up" on the angle until it does. Then readjust and cut/fit the other end. Repeat around the edges until the last end of the last trim piece is fitted properly. The last joint will be the worst, so try to put in an inconspicuous place like the back.

Hope this helps. You might want to go through a few scrap pieces to get a good approximation of fit at the corners before tackling the final trim pieces.
