I have been trying to learn to do this for some time and I just cannot seem to achieve it. My problem is making the lines perfectly straight and consistent and after a lot of frustration I started wondering if manufacturers are using a jig of some sort to do this. All I have to go on is youtube tutorials and they all use a flat piece of stock with sand paper wrapped around it but this just doesnt seem to work for me I cant keep the lines straight and the flawless straight lines I see from some of my favorite manufacturers are taunting me to the point I am trying to devise an idea for a jig. After a lot of testing of sand paper finishing with a scotchbrite pad seemed to give me the luster I am after but again, sloppy crooked lines is the result whether i finish with paper or pad. There has to be a better way then just doing it by hand which is clearly never going to give me the results I desire, does anyone use a jig or know how to make one?
