Don't know if you already attempted this, but if it's not too late, don't do it. I played in the era where we always had to torch a blade. No way you can change a lefty to a righty. First, you'd dry out or burn the wood. Secondly, the fibreglass doesn't stretch, the backside fibreglass of the blade is longer than the frontside, so it would buckle. . It will also become unstuck to the wooden blade. Better to just same it as a relic of what the cavemen used before there were composite one piece sticks.
