In Part One we discussed the various foam types available (Polyurethane, Superfused EPS, and Block-Cut EPS). In Part Two we discussed the various densities of foam available and how to find the exact right strength-to-ratio fit. In Part Three, Blank Selection, we’ll help you choose the blank that has just enough foam for your design.
Selecting the appropriate blank for your build is pretty easy to do, but selecting the RIGHT blank will reduce your time, workload, materials waste, and allow you focus your attention on fine tuning the details of your design.
US Blanks offers 85 blank models, from
Shortboards to Guns to SUPs. Your goal will be to envision your desired final
design, and then fit that design within the shape and dimension of the foam
blank. For this example, let’s assume that
you’d like to build a shortboard with the dimensions 6’1” x 21” x 3”.
|No shortage of thickness in these Longboards|
There are 3 main criteria that you’ll assess when selecting the best blank for your build, in this order.
Genre - US Blanks categorizes their blanks by 6 categories; Shortboard, Fish / Egg, Funboard, Longboard, Gun, SUP. Page 10 of their blank catalog has each Blank grouped by category (see the attached document). Narrowing the genre will help you to find the blank with the correct outline and rocker for your desired design. Obviously, for this example we’ll be selecting Shortboard genre.
Height - Selecting the right height is the best way to reduce wasted material and time in your build. Why buy 10’ of foam when you’re planning to build a 6’ shortboard? That said, it’s best to select a blank with just a couple inches of added height beyond your desired design, just to allow for subtle adjustments or potential errors. Since we’re planning to build a 6’1” shortboard, consider selecting a 6’2” - 6’4” Shortboard blank.
Width & Thickness - Once you’ve selected Genre and Height, you will likely have narrowed your search down to 3 or 4 blank options. The selection can be finalized by determining your desired Width & Thickness. We’d like to net 21” of width and 3” of thickness.
