>With a miter saw I want to cut the end of a beam (fig. 1 in the sketch I posted here: ) so that two miter cuts (arrow heads, fig. 3) at 54.4° result at their intersection in a given angle (base angle, fig. 2 and fig. 4) of 10.3° in my example (for a more visual description one might check this video here: where, however, it gets omitted to mention that bevel angle need to be applied). I did a test cut with setting the bevel angle at 5°, tilting right and left respectively for each of the cuts, what resulted in a base angle of approx. 8°. So the approach seems to be correct, but I need to be able to control it and hence I need help in calculating the bevel angle to set at the miter saw when cutting the two miter angles. Any help, even hints pointing into the right direction, is greatly appreciated! TIA!!!
