    My s510 was indexing rough so I grinded the rounded point off my cam plate(this point was what contacted my side plate. I did this in attempt to make the indexing go smooth, instead it got much worse; oops, shouldn't have done that.                                  I eventually concluded that the roughness was caused by the rounded point wearing away the coating on the inside of the side plate.

          So, can this problem be remedied at this point without new parts? I was considering polishing the side plate where it contacts the cam plate and then welding a point back on the cam plate or or something. This would make metal on metal contact though so idk if that will actually work. Thoughts anyone?

    So metals, particularly not super hard metals, actually tend to gall when rubbed against each other. Even if polished pretty smooth, they'll still feel rough. Assuming you haven't removed so much material that it no longer functions properly, the solution is probably just a quality lubricant. a PTFE thickened silicone grease is probably a good option as it'll have good cling and the PTFE will help it tolerate load and resist wear in a way that pure silicone won't. 

    Of course there are hundreds of other lubricants which would work well, but there are a surprising number which won't. Something to keep in mind. 

    I hope that helps. :)

    well you took a good amount of meat off that part  so welding would be a good starting point but a new part might be your best choice or at least have one on hand

    many sites offer the part but Air Arms has the best price at 19.89 pounds about $25.68 today

    now I don't own this rifle but I do like factory parts as needed, is this an as needed time only after a repair try will you know

    laser welding a bearing ball might be a interesting idea, a small pocket and a magnet to hold in place but that's my imagination running wild again

    down the page for the part price  S560 part number but you knew that

    just my 10 cents
