Hot wire guide

Hi Everybody - Anyone have success with this idea? I did a search and found one post by “Cross300” who was going to try, buy that was it.

Before you all tell me how much easier it would be to make a set of rocker-foil-“stringer esq” pieces to put on each side of my EPS block - I don’t mind some extra work, and I don’t plan on making the same exact board again, and again.

My thought is a flexible material, w/some spring to help “true” the curves (I have good success using an old sail board sail batton (?) to do rail curves.) which I could put some small angle pieces on - for mounting to the foam block - and then run the hot wire along it.

Thanks - Taylor
