how to straighten radiator fins?

[Acidblast]

Hey guys i just bought a used radiator from the BST forums here. Some of the radiator fins are bent. I searched online and i could use a tool called a "radiator fin rake".

now my question is the radiator has a ZIG-ZAG pattern, how would i go recreating the zig-zag pattern using the fin rake?

Get some bamboo skewers that you would make shish-kabob with and do it by hand, it will take some time so be patient.
