I have just bought a new drill press, the General International
75-025, and am trying to attach the General International 70-900 mortising accessory to it. Whenever I turn the unit on with the mortiser installed, it spins a couple of seconds and then the arbor and chuck fall out of the quill.I have followed the instructions for installing the arbor and chuck and the drill works fine with an ordinary bit installed. As far as I can tell everything is correctly set up. The rather brief instruction manual contains no trouble-shooting guide.
Is there a way to install the arbor in the quill more positively? Could there be something wrong with the mortising bit? Alignment?
I would appreciate any help on this as I am new to this kind of setup.
Best Regards, Jack Fearnley
