Shafts, bearings and circlips....

Thanks John, not come across those before and I thought I'd had some experience. Just shows you never stop learning! Presumably they can be used internally as well as externally?

What's your thoughts on using Loctite v a retaining lip and cover plate? I'm keen to minimise machining efforts.

Edit: of course I have seen those before - retaining gudgeon pin on pistons, I'm losing my marbles :(

What John posted is what I'd call a snap ring.

Another option could be a flat snap/retaining ring. Think a circlip with a continual rectangular profile, which usually just have a notch in either end to help springn them apart.

The rectangular section ring works for me and is easier IMHO to machine the groove for.

Still wondering about use of Loctite to retain bearing outer race. If I go that route it can be 5mm mild steel plate with bearing pressed and glued in. If not it needs to be 8mm at least to make room for retaining lip and groove for snap ring. Plus two more accurate machining operations.

I'm trying to make this construct-able at low cost in the future.
