The stainless steel jump rings seem like they could add up to an substantial total given the quantity you need ( four per disk). Fishing and support ing goods stores (e. So Yesterday By Scott Westerfeld Pdf there.

Bass Pro Shops, Gander Mountain, Sports Authority, Dick's etc.) have small 'split rings' (like those used for keys) which are used for fishing tackle. They usually sell in paks of 5 or 10 for a little more than what one jump ring seems to cost. If true stainless steel is not available, some fishing ones are labeled as 'English stainless' which is actually some kind of plating on either steel or brass, but seems to resist corrosion fairly well. It seems like these would be easy to install as compared to having to bend open and then bend closed the split rings, as long as you buy relatively thin split rings. If opening the split rings is difficult for you (as for me, having lost some feeling in my finger tips as I get old and decrepit), you will find very near the split rings in the sporting goods store a tool called a 'split ring pliers' (for about $10). The pliers make opening them simple. I just have some questions.
