3D binding offset map

This chart shows possible fore/aft locations of various bindings when used with the Burton 3D insert hole pattern. For each binding, a vertical series of x's indicates locations where the center of the binding disk can be positioned. The x's are grouped - each group uses the same 3 board inserts, but different holes in the binding disk.

At first glance, this chart would appear to be a useless exercise in trivial minutia. But closer inspection reveals hidden subtleties:

• Burton binding disks with a single set of holes, and Bomber TD1s have large spacing between some fore/aft locations, which means you might not be able to dial in the ideal stance width and setback. It's another reason to upgrade from TD1s to TD2s.
• For TD1s, the possible locations for the binding disk center holes was highly constrained, which explains the nonuniform fore/aft positions. Because of the binding disk hole placement, you don't get additional positions by rotating the bindings disks 180º (which you could do for a 0º cant disk)
• For TD2s, more uniform spacing would result if the hole pattern on the disk were shifted a few mm toward the edge near the center holes, but doing so would also reduce the total possible range.
• For TD1 and TD2, you can theoretically rotate the binding disks 120º, which provides additional fore/aft positions, but those positions will also offset the binding on the board widthwise, and may cause weird stress patterns on the inserts.
• There is a 1:1 scale pdf file of the image. You can print it out on a transparency, then overlay the transparency on top of the board, aligned with the inserts. Why you would want to do this, I have no idea- it's just a random thought.
