Re: Replace cotter pins with welding rod
The problem with either the wire or cotter pins is that once bent, they may break due to hardening. This seems to be especially true of overly-expensive cotter pins which seem to be a fairly brittle alloy. At least with recycled wire (see post above), you're not throwing away a lot of money when replacing. Cotter pins are a royal PITA to unbend and pull every time you want to make an adjustment. As mentioned, they are prone to become "meat hooks." Both the single wire and rings are better in this aspect, being easier to remove/replace with fewer sharp ends. Being able to quickly remove pins makes it more likely that fine adjustments will get done.
