rails

...here few steps of how to do the top part of the rails (+++)
in the first and second pictures you can see one side with a rail "band" and the other kind of 90º yet
several passes with the planer to do one band; then repeating the process in the other side of the board; after that you make a second band besides the first, in both sides, then blend the beveled edges
3 picture shows shallow passes to almost finish the rails with the planer
4 picture shows a closer view. click in the picture to see in detail
then blend everything out with sandpaper and/or sandscreen

+++normally I do the bottom part of the rails first (most good shapers do in that way too)
but sometimes I prefer to start in this way
