Hi - I need to rotate the cutters in my planer for the first time. They seem to be impossibly tightly screwed in ! Clearly my No 20 Torx hand screwdriver was not going to do the job nor could I move any screws with with an L shaped Torx key. So I have now tried an impact driver. This released the first screw without a problem but the end of the Torx bit itself sheared off when I tried to undo the second blade. Are they supposed to be this tight ? Should I proceed with the impact driver (more No20 Torx bits already ordered !) ? When replaced, how tight should they be ? Any help or suggestions gratefully received !
On a related point - how do you tell when the cutters need to be replaced ? I have been shoving seasoned oak through the machine and it’s been getting really hard work. Also the boards have got stuck on occasion so I figured it was time to rotate - but is this right ?
