Bevel 120 degree rail cap butt joint or not?

iceman50July 5, 2009

I am almost finished with my IPE deck, but I have a question. I am using a two piece cap rail; a 2x4 on edge with a 5/4 x 6 inch top cap. The deck has several non 90 degree angles. On the straight sections, I did a 45 degree bevel on the butt joints with the top cap over the posts, but I am not sure how to handle the 120 degree angles. I would prefer not to use a non beveled butt joint, but it is not exactly clear to me how to finish off the 120 degree intersection if I use a 45 degree bevel for this butt joint.

Any help from the experts would be appreciated. Thanks.

Wouldn't you just cut the joints at 60 degrees? Or am I not understanding your question?

I am sorry that I was not clear, The question that I had was rather than doing a simple angle cut butt joint, I would prefer to do that same angle cut with a bevel so that you would have a beveled lap joint, so that the butt joint gap would not be visible. However, because of the bevel, the front and back edge mating surfaces do not form a nice intersection, and I am not sure of the best way to form these.
