Not a fan of the trimmer this unit comes with as it never seems like it's precise enough. Starting fiddling with it and was hoping to mount a drill chuck to it so I can run a Giraud or Gunworks trimmer on it. Seems like it would be the perfect setup where I could trim, inside and outside chamfer all in the same step. Not sure of the thread size on the cutting head but figure there has to be a way to adapt it to mount a regular drill chuck on it. Anyone?
