i have done the opposite as everyone else and cut the blade end. drilling the hole was no problem using a drill press, a couple of clamps and a new speed bore bit (with the little screw tip on the end to start the hole).
you can't cut 6" off a shaft because the existing button hole is centered at 6". you have to remove almost 6.5 " to clear the exsisting hole. this doesn't really matter if your cutting a pair but if you trying to match a 9.5' to a 9' oar, it is going to be 1/2" shorter unless you don't mind having half of the existing hole at the connection between your shaft and blade.
use the 6.5"' section that you remove to do a few practice holes for accuracy. if you have problems with this then call a friend with more tools.
measure carefully for your hole and start by using a small punch to start the bit through the plastic and into the aluminum. aluminum cuts really easily and can be cut, drilled and routed as easily as wood but- always use sharp blades and bits and wear eye protction!
