Like most things that break in, this I think should be expected as the surface improves. I've torn apart a couple old piston and rod, and the surfaces on the ball were less perfect. I recently read about Gilbert ball sockets being reset.
A look at the timeline of various designs may show that Cox was the first to use their process successfully, but I don't know much about other makes. G-Mark appeared late in the game and appear to be made just like Cox. Swaging at elevated temperatures seems impractical from a production standpoint, because it would likely require finishing the piston OD with a rod in it. A few hundred degrees makes no difference for steel, it would have to be near red heat to soften enough to matter. Alloy could be a factor if work hardening allows it to bend a certain amount, but after that it fails.

Re: Ball - Socket Joints
Yes I hope it will work maybe with luck I could make a part that could replace the old one and make one for others who have the same problem if the pistons are the same inserting the new retainer cup will not be a problem I myself can't wait to repair it, it's just a matter of time between all the projects that I have to do, the most important thing is what will be used before the rest, currently I'm building a motorized bike that looks like a motorcycle it wil be My way to save on transportationrdw777 wrote:davidll1984 wrote:Making the retainer cup will be easy I think
I hope you are able to make the part David…… Challenging but should be possible if you have a small lathe…..You may just come up with a procedure that saves a lot of old Wasps… Good luck and please let us know how it works out

Re: Ball - Socket Joints
David do you have a pic of it I don't quite understand ? Sorry, sounds like you have a broken in half cup to fit the boss in the piston ? It would bee very hard for me to extend the cup set length *make it go deeper) I will have to get my mind set right to do this so as maybe not mess it up and Yes I will share Robert .

Re: Ball - Socket Joints
Resets are needed less because the material work hardens every time you reset it.
