Dynamite .15 Collet on Fastech nitro
i purchased a fastech nitro 3 years ago,never ran it.figured i'd take out the flexshaft today to lube it and run it this evening.unfortunately,when I was removing the nut,2 of the 3 fingers that clapse the shaft were broken due to overtightening from the factory and fell off.i then tried to remove the nut from the flywheel using an allen wrench and a 10mm open end.it would not budge.it was at the point of bending the allen wrench.anyone have any suggestions to remove this from the flywheel,as it has to be removed in order to put another one on.thanks in advance.
