Heard of it, never tried it. I remember years ago, someone on the ***********, guy from Alabama, reported trying it in a lake or maybe finding a log in a lake and making a bow from it.
Honestly, it doesn't make sense to me but I know that old growth logs found sunk to the bottom of the Great lakes where they are preserved forever are in high demand right now. Guy is making a mint recovering them based on a documentary I saw. I'd love to try one in a bow
I have retillered a solid fiberglass kid's bow I got from Goodwill. I just used a rasp, files and scraper like it was wood. I would not hesitate to try a heavier bow. Fiberglass splinters are a pain. I wore leather gloves. Don't sue me if it doesn't work. My effort sure made a kid happy at Cloverdale this year
Peace.
