Well here goes... Aluminium frame router design

[CharlieRam]

Heres a little video of what I mean, if the screw is pushed upto the sleeve, the seal starts to spin. I'm wondering if the spacer O/D is catching on the seal and when it is butted upto the bearing face it is dragging it round? Also I'm still not sure how freely the screw should move, I was expecting it to spin a little like a roller skate bearing, it seems to have resistence even without tightening the nut. The spacers are different lengths but if I put them the other way round the outer one would be too short and be inside of the seal, the way they are now both sides protrude from the seals.
Any help and advice greatly appreciated.
Cheers, Charlie
