To all of those who have posted questions and comments about restoring and rebulding teak and holly soles. I have found the following site that I think might be your answer: WOODWORKINGFORWATERCRAFT.COM (AKA) JR@WOODWORKINGFORWATERCRAFT.COM
. They are located in that great seafaring state of Arizona. JR is very helpfull. Here is where you find 1/4 inch thick teak and holly, not that 1/64th inch ply.
