Good morning,

Several formulas about to machine crushed core to a profile then expand again

have done repairs to Dornier wing flaps where the core has to be square to the centre axis not follow the wing surface so the core is crushed till its almost solid,a profile is machined on it using the correct formula then its pulled back into shape and has the perfect profile of the flap

Also done a satellite where when the core is cooked we had perfect honeycomb hex,s machined from stainless that we had to check and re size every single hole-And there were a lot of holes !!!
