The Texas-Cut is more of a straight cut down the leading edge of the propeller blade. Along the leading edge that you show in your picture as the (spoon and cup area). This area will also control your leading edge pitch numbers. Your trailing edge (lift area) is the area that we cup the trailing edge on in the older style propellers. Your picture is more of a older style propeller design. Some of the new designs are a lot different. Your Barr-Cut should be cut at the same angle as your trailing edge surface angle. You have some interesting (pitch areas) in your picture as well as your (lift area). Keep Testing And Learning About Different Propeller Designs. Thanks For The Pictures, Mark Sholund

Polishing will throw off your balancing unless you continue to balance while polishing. It will also cause some cavitation on some applications. Another good tip is to have a metal lathe in your shop with a 3/16” or 1/4” drive dog installed and chuck it up in the lathe to make sure the blade lengths are even. This will save you hours in the balancing of your work. Keep up the good work! Happy Holidays, Mark Sholund
