Perimeter stringer thought

If I used 4x 1/8 strips for the perimeter stringer on a balsa sandwich board, but stopped two of the strips about 10 inches from the tail, leaving just 1/4 of perimeter stringer aft of the “bump”, do you suppose that would give me a little extra flex in the tail so I could run a flatter rocker? Or do you suppose that would create a break point right where the 4 strips transitioned into the 2 strips, that would eventually result in failure/breakage?

nah that will be sweet to do that

i swear i think these type of boards are virtually unbreakable

they will more likely crease but i dont think the perimeter width has to much influence on in fact i think the narrower stringer would have more give so less likely to have the board crease…

seems strange but that is just my opinion

Logically that should make the tail have more flex. Just dont make the end points abrupt, build it with all 4 then belt sand away two over 16" or so.

Shwuz,

That’s what we did with my balsa perimeter stringers, to make the wings, see pics in this post.

I don’t think it will effect flex much, stringer depth influences stiffness more than width. If you want more flex you should foil the tail thinner.

Good time on this post! I’m just playing around with how to do this on my next board. Definantly gives me something to think about.
