So I believe that your problem is that you cannot "lock" the wheel on the axle because the wheel is too large. Yes?
Here is a solution:
You can dremel the inside of the tip of the quick change aluminum bit until you can "lock" the wheel. I did that with my 950 and it worked for me. But you have to be careful and do it little by little until the fit is perfect and be careful not to break the bit.
