Babit Bearings

[ETC57]

I tend to agree with Pix Man on finish your shaft should be reasonably hard with a fine finish, when I was a much younger lad we used babbit bearings in the the 36" jaw crusher at the gravel pit.
When it was time to re bearing, the crusher went out for service so they could check and resurface the shaft before pouring new bearings.
Simpler times, make small rocks from big ones!
