How can you cut kevlar with a cutting disc? Can you show what tool you use?

2) for LE there is the spread-tow as you can see and i use some colored(black) microbaloon epoxy mixture i apply with a sirenge in the mould before inserting the cores , when the cores are in i go around the LE with my syrenge again , so when i close the mould the excess black epoxy get squeesed out .
Nice trick!

4) i don't reduce anything for skin thickness, cores are cnc'ed 0.3mm thicker .

i made a press to close the mould ,way more then a vacuum set-up can pull .
Does the wing expand after pulling it out of the mold? Can you measure the thickness of the airfoil in the mold and on the finished wing?


Thanks!
