So I bought the chain only to find out I need a Regina chain peening tool to peen the tool the right way. Regina chains use a flat rivet master link instead of a dished head rivet like DID. Anyone have any brilliant ideas on how to peen the thing over without the Regina tool? What I have found so far is: -use vise grip to distort end of pin (aka make oval) -use thin blade dremel and cut a shallow (1/32") X in head and use standard rivet press head to flare. -use block a steel behind link and use a hammer on front side to work a peen around pin.
