I have a 1/4 inch shaft that’s in two bearings at each end which are in turn in bearing blocks. I want to stop the shaft from moving left or right. I have a 1/4" ID x 1/2" OD shaft collar but it’s too big - it rubs on the outer edge of the bearing, and I can’t seem to source a smaller one.
Other option seems to be to cut a grove in a split ring - but I don’t have access to a lathe and it’s only a couple of shafts - too small a job to pay someone to do it.
Any other options or anyone have a small metal lathe I could ply with beer and / or cake?
