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:

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:

What are your thoughts / experiences / suggestions?
What fabric you use will determine how many layers you need. As an example, a 200gsm fabric would require 4 layers to do what 1 layer of 800gsm would do. This is relative though, and there is the possibility that 4 layers of light fabric would be more rigid than a single layer of heavy fabric. Additionally, the term “safe to ride” depends on how fast you wanna go.
