If it were me, I would put the piston at BDC, park out the through-skirt hole onto the piston and cut that first. This is what I have done on my Derbi Metras and it works very very well.

I will suggest windowing the piston versus slotting it all the way through. The imbalance and rocking from the slotting wears everything pretty significantly.
