Can anybody help I have a coronet minor I need to get the grub screw out that locks the head spindle it’s on the left hand side next to the drive belt pulley wheel a 3m alun key is to small and 4m is to big
It will be a 1/8" Allen key for sure ! Personally I would buy a single or a set good quality keys, Bacho, Unbrako, or any well known brand, many of the cheap unknown ones leave a lot to be desired -- to soft mainly.
