Just ignore the plank functions, Nethskie.
This couldn't be simpler, really. Pop it into the 'shader' port of a 'transform shader'. Now you can rescale *almost any shader.
This shows the wood multiplied to 1000x, the camera is 1000m up(see preview 'vheight');

You don't need to have the same values in each scale field, scale away!
*** Edit: This is probably something I should have included with the file, it's an easy, one-step scale/move function. I will do in future uploads, where applicable. It's a good shader to get used to because you don't need to fiddle with loads of sets of numbers inside. Any input shader can be easily divided or multiplied in size and also moved around in the world space.
