bevel both ends of 2x4 with circular saw
I need to cut a 2x4 into a trapezoid shape (not parallelogram). The plan I'm following gives the measurement of the long side as 22".
Looking at my saw from the operator position, the blade tilts from lower left to upper right when set for a bevel.
At the end where I do the first cut, the board is of course slightly longer on one side than the other after I make that cut.
I then draw a line 22" from the cut end, holding the tape measure against the longer surface. To get the proper bevel and complete the trapezoid, I lay down the 2x4 with the shorter surface against my bench.
Now where do I place the blade -- how do I line up my guide -- so I get the correct length of 22"? On the cut line? Will that give me exactly 22"?
