Honestly, I have no idea. I briefly considered trying my hand at it, but I didn't want to invest in the extra equipment and supplies. :) I messaged you, so if you have a price on mind, or examples, feel free to let me know.
I would have to buy good parts, make the molds and then do some layups. Then I would need to test fit to make sure the molds are the proper shape.
I cant figure out how to clear out my inbox on this tablet, I will when I can sit down at my desktop.
