# Reducing a 9' board to 4'6" in AKU

Hello,

I was sent a 9' template ofan original Simmons board and wanted to see what it would look like as a 4'6" board.

Here is some advice I received on how this might be done. "

"You have to remove any slices that are 2'3" or less (half of the 4"6" you want to remove) from each end. Then, re-add tail and nose slices, shaping to your preference. If you want to maintain proportion of shape, rule of thumb is 1/8" of width for every 2" of length; add width if adding length, subtract width if reducing length. Keep wide point at same relative position. On model, measure distance of WP from center and calculate % of total length. Use that % to determine placement of WP. Tweak nose and tail width to match up"
I have little experience with the program so was interested in suggestions whether this was the best way to do such a rescaling.

If the 9' template is an aku file, then you can preserve the tail and nose "slices" (or any slices for that matter) by exporting them to a seperate folder (name the folder "Slices" so its easy to remember) before deleting them. Then, after you have reduced the length and width, you can "import" these slices back into the file. That way the shape of the slices will remain consistent to the original slices. Unless you want to re-design the shape of the rails, that is.

Thanks TP - If I want length reduced by 54", according to your rule of thumb this would mean (54/2) * 1/8 = 3.375 to be narrowed.  At the widest points the board is 23 7/16" so the board would end up 20 1/8" wide. Does htis ound right?

That's a good question Bob. It seems to me that the 1/8"-width-for-2"-length rule works for a functional shape when changes in length are under 1' longer or shorter . An even then, both nose and tail width need to be adjusted, as well as rocker, and the resulting shape needs to be checked by eye (notice that when you change width in AKU, it automatically adjusts tail and nose width). The mini-simmmons shapes we are seeing don't follow the 1/8" rule, otherwise they would look more like alias. Goddard's belly boards are very Simmons-esque in outline, but never less than 21"-22" wide.
