Longboard rail design

I have the shaping 101 video and have seen how john marks his rails. He puts the 2" and 4" marks at the center and so on. I am going to shape a 9’8" and am looking for a way to get a clean 50/50 rail preferably pinched. Does anybody use this same method when making a longboard? If so what are your measurements at the center, nose, and tail. Thanks for your help, P.V.

would very turned down rails in the nose, very rounded 50/50 in the mid, and super turned up rails in the tail work well for a 9’10"???

You are talking about some fundamental design elements used by Morey-Pope in the The Blue Machine and the Peck Penetrator, cira 1967. Both of these boards had minimal forward rocker, putting most of it in the tail (kick tail)to complement the high rails and rolled bottoms. The down rails in the nose do not have to be hard or edgey - you want them to lift, not break away! You might want to check with Jim Phillips about how to effectively combine all of these elements. There is much blending of engineering and artistry with this design. And it works!

personally, i would stay away from “very turned down rails” in the nose. i think it would be easier to steer and a little faster but much easier to catch an edge. i’d keep it soft and simple - smooth. turned up rails in the tail will make it harder to turn, but it will noseride like a champ steve>>> would very turned down rails in the nose, very rounded 50/50 in the mid, > and super turned up rails in the tail work well for a 9’10"???

The idea of the roll in the bottom of the tail is to specifically facilitate rail-to-rail movement; turning! The idea of the down rail and flat bottom is to replicate a wing shape - a shape that will develop lift when it’s moving. Again, I refer any one who is interested in this design to 1) if you can find either a Morey-Pope “Blue Machine,” or a Hynson “Stretch,” check out the bottom and rail contours and/or 2)run these design concepts by Jim Phillips, he does shape them!
