Replicating is a lot easier with a cnc shaping machine than by hand shaping.

It is possible to be pretty accurate replicating a surfboard by hand. It will take some time, making sure all your cuts are right, checking rocker curves, deck crown, rail profiles etc. But, in the end you can be right there with making one board the same as the other.

To replicate a board with a machine you can either scan the board you’d like to replicate with the machine… if the machine as that capability or, you map the board and input the numbers into the software program and build your computer surfboard file that way.

Basically mapping a board for program entry is the same as mapping a board for replicating by hand. You make a list of all the particulars… numbers… of the board like rocker, what the rocker curve is like at the nose tip, at 6 inches from the tip, 12 inches etc. Then the same for the tail. What the various measurements are of the outline or plan shape. Like width at center, 12 inches from nose and tail, 18 inches from nose and tail and so on. Rail apex point at different potions along the boards length as well as thickness at 6 inch intervals down the length of the board.

Once you’ve got all your numbers then you input them into your computer program and build your computer model for the machine to replicate. If you hand shape you reference all your numbers as you work through your shaping process.

In the end whether you hand shape or use a machine you have your board. The one thing you don’t have when you hand shape is knowing what the over all volume of your board is. When using a computer program you get that information.
