360 - mini hypnodisc

[Eventorizon]

Found a few tutorials which explain it but lacking on tools. The shaft on yours was only 6mm wasn't it? The Hk-4035-800 can have an 8mm shaft. If I support it in the same way as you did on 360 then it should be fine. Might work out a way of supporting both ends.

Edit: Also cos of the way a Brushless is assembled, I don't think you can widen the shaft very much. It might be better to just give it good support.
