Cutting a straight line takes practice with a AG but can be done almost straight with practice. Short "touch" cuts, connect them to make a groove, then follow the groove deeper. When done, Kiss the cut with side of disc to square. When you really get good you can follow the line in one pass to make a groove or cut. You have to man handle the thing though or it will bite you. Real men take off the shield. But I do use googles and face mask.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
