Macnum wheel hub mod

[madmax]

After building macnum I found that the rear hubs don't have a spacer in the middle of the bearings and found that when I tightens the wheel nut up their was a little bit of binding. To solve this I have used a pice of brass tube 6 x 0.5mm and cut a lenth of 4mm to sit between the bearings this allows you to tighten the nut up properley.

And on the front I found the same problem but it binds up compleatley but putting a pice of the brass tube in of about 7mm and grinding a tiny part of the flat grove out stops the front from binding compleatley
