i bought a cheap set of 3-jaw bearing pullers on craigslist that the fellow said were barely used and the 3" version was slightly damaged but functional. On closer inspection the swivel end had snapped off the screw and one of the puller jaws was bent.
But what i'm trying to figure is how was that swivel attached to the screw? Heated and pressed, or maybe the back edge was rolled over to secure it to the screw? Also i don't have the broken piece to know if it was a ball end or cylindrical.
This same type of construction seems to be used on C-clamps and maybe some jack screws.
Has anyone ever built these and know how it is designed and put together?
