To make a miter cut, precut the wood slightly oversized (1/4" or so) and then trim each end with the trimmer. When making multiple cuts of the same length, the Measuring Attachment speeds things up and ensures accuracy. To make a compound miter you should make your miter out on the trimmer and then using a block, tip the wood to the desired angle and make a second cut.
To miter angles other than 45º, depress the pin stop and loosen the thumb screw to move the gauge. Use a protractor or adjustable bevel square to set the desired angle. You do not need to tighten the thumb screw with anything other than your fingers. Using too much force will break the gauge. To make a chamfer cut, first cut the piece at 90º. Then, using a block, cut bevels around each side.
Set your gauge to 90º and trim your wood to the desired length. Draw the shape you want and then use a series of cuts to achieve your round. It helps sometimes to remove one or both gauges to make it easier.
