Question on triple blade chainring



The more expensive chainrings has milled out pickup teeth. The two larger chainrings on my tandem has little studs riveted to the blade. Each has four holes and I pressume there were four riveted studs in each hole. The large ring has one missing and the middle ring has three missing with the third riveted stud half loose. Do I have to buy new chainrings or can these be repaired?????

Thanx in advance

Keep those wheels spinning!!!!!
