Having got a few more Staniers today from preorder I had 8 that had no problem at all.
The rest had minor issues with the 50' brakes as bad as yesterday.
Having discovered the slop in the axleboxes I thought I would try to pack the axle a little.
This has worked very well with some very thin plastic bent to drop in the axle slot.
It needs refining a little, maybe with tube around the axle (possibly brass when I get some) but it saves all the grinding.
The white is a little thick but I left it in for the video as it was easier to see than the black.
