Mounting encoder/cutting 12 in axel

[intellec7]

I was trying to mount the vex shaft encoders on the squarebot, but found no easy way, so I took it apart in hope that whilst I would have some idea as to mount it, but no. :-) I think what would help is if I had a aprox. 5.5 inch axle. What would be the best way to cut the axle? More importantly if it requires a bandsaw, where do I have access to one :-p
Thank you
