Ripping with a circular saw
How do you safely rip large sheets of plywood and similar materials with a circular saw? (I do not have a table saw.) In the past, I've put the sheet up on sawhorses, begin the cut from one side reaching into the wood as far as I can, then stop the saw and go to the other side, restart the saw and finish the cut. But it doesn't feel like the safest way to do it - I am stretching to reach the center of the board, and feel uncomfortable with the saw coming at me for the second half of the cut. Is this the proper/safe way to make the cut? Or is there a different method that someone could describe to me? Thank you in advance!
