Another question for Herm, if apologies in this thread!

If I understand it correctly, one of the reasons the peening babbits is to allow the babbitt to have full contact with the engine block.
Is also the reason to compress the babbit to achieve a higher density.
If so, how deep does peening effect go, it looks like you're peening very hard.

After many mil and bearing clearance has become excessive,
how much depends on,

Wear of crankshaft?

Wear of babbitts?

Compression of the babit?

I understand that it may be due to various causes, but is there a rule of thumb?

Hard for me to explain, hope it's understandable.

Thanks
Jorgen
