As you can see in the pictures, I milled out a battery space out of an kinda old Sector9 downhill deck. I milled out 4 layers of the 8 but because of the concave “only” the part that is blue is really that deep.
I do have carbon and epoxy and I am intending to support the structure like in this turorial: tutorial by e-sk8.fr
My question is: How many layers of carbon are required to make it safe again to ride on?
Also: Should I add another layer over the whole underside of the deck, too? If so, I would do it as described here: hand lay carbon tutorial
What are your thoughts / experiences / suggestions?
