I have a shaft cutoff machine bought from Golfworks several years ago.  I am a hobbyist who has worked on clubs for over 35 years.  The cutoff wheel needs changed.  When I went to change it I became puzzled how to remove the old wheel.  There is not a standard nut or bolt holding the cutoff wheel.

Can anyone help me with information on how to remove the old wheel and install a new one?

Thank you,

Tom Campbell
