attaching hinges and springs to resin moving jaw

i ordered a fox resin blank and hinges from dreamvision creations and i am currently looking into ways to attach the hinges and springs to load the movement

i decided to use the L hinges as to minimize any need to drill into the resin (cause im terrified of cracking it) i read somewhere that a 2 part epoxy glue would attach them just fine

but my main concern is attaching the springs as i cant really envision a way to attach them without drilling

i know some people use elastic instead but i think elastic would wear out far faster and wouldnt have as sensitive movement as a metal spring

does anyone have experience drilling resin? or more specifically drilling into mask made by DVC
