I have several flag cases to turn out for an upcoming event. I've never done acute angles on the table saw. What is the most precise way to make the 67.5 miter? I don't want to use the chop saw. I prefer the accuracy of the table saw, though I know how to do them on the chop saw.

From contributor J:
Felder sells an add-on for your slider that makes acute miters easy. It is called the EGL. They also have a model called the DGL. You can search the Felderusa.com website using the part number 401-152 under tooling and accessories. Even if this unit won't work for you it may give you some ideas on how to make a jig for your table saw. The EGL pivots near the saw blade and has a very large scale making acute miters and tapers possible from zero to 90 degrees.
I did end up making a wedge with a fence and attached to my miter gauge. Then mitered with the work standing up. Worked out great except I had to make the box and lid separately due to it being too tall for a 10" table saw.
