Well here goes... Aluminium frame router design

They're different lengths, well mine were!

Are all pieces there assembled like that?




So if the whole bearings are moving in the housing, then shim the OD of the bearings. If only the ID of the bearings are moving, then shim only the ID. When shimming, dont shim between them, but outside in both cases.

If not freely rotating, then something is not right. It must be something simple, so just check again

It's all there apart from the lock washer, do I need one?

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
