Seeking wisdom from the collective.
Nice little gift for me on the last monday before xmas. One of the sieve shakers broke down over the weekend, a little exploratory surgery revealed the cause to be wear to the cam that gives the shaker its vertical motion. This was replaced only a year or so ago as the same failure had happened to the original part (itself nearly 30 years old, don't make em like the used to or what??) this at a cost of £220 for the part.
This is the part
This is the cam that has worn, this wear was caused by a freely rotating follower wheel with the whole mechanism submerged in oil.
This is what the profile should look like across the whole width of the cam
So the question is can this be fixed? I believe the material is cast steel (it is definitely a cast piece) that has then been machined. Could I build this up with A18 mig wire grind back to shape and then try hardening it? Or is it a case of new part needed?
Thanks in advance
