Hi guys and gals. Today I replaced the chain on my bike. This is the first time I did a chain. When I flared the ends of the pins on the master link, I measured the diameter with calipers. After flaring as much as I could, the diameter only increased .4-.5mm. Is this enough? I'm a little nervous about riding it to work tomorrow.

 

got any close up pics?

 

and what are you using for a riveting tool?

 

Here are some pics and the tool I used.
