CSE Step Down Super Swiss Ferrules (full set one female and two males)
CSE Super Swiss step down ferrules are made in Vermont and represent the highest quality in design, workmanship, and materials. Made from Nickel Silver these ferrules work great for both new and restoration rods. The Super Swiss step down design features two diameters in the male slide. There is a pronounced "step" that drops to a smaller diameter. All ferrules are tabbed to work with hexagonal blanks.
Would you like us to blue the ferrules for you? We offer the service here: Ferrule bluing
Please note: Ferrules need to be lapped (fit) to each other. The male ferrules come very slightly oversized (roughly 0.001") than the inside of the corresponding female ferrule. To fit ferrules we offer a set of polishing paper that works great. You can find the papers here: Polishing Paper.
A few things to consider when ordering ferrules:
1. Ferrules cannot be mix matched. By this I mean if you have a rod that has a good working female ferrule and a split male ferrule both will need to be replaced. Ferrules work as a team and are fit so close getting two different styles, manufacturers, etc... to play nice together just doesn't work.
2. Ferrules are measured by their inside diameter.
3. Ferrule sizing: Ferrules are size by their inside diameter and are measured by the 64th of an inch. So a size 10 ferrule is 10/64". I have included a conversion chart below to simplify sizing. Sizing ferrules requires a degree of precision. You will need to use a caliper to ensure a proper sized ferrule. I recommend measuring around 1/2" up from the end of the bamboo. For restoration rods, in particular, the numbers might not come out perfectly. For example: a size 10 ferrule measures .1562" on the inside. Now say you measure your blank 1/2" up from the end and it comes in at .1570" (there is a bit of play allowed on both sides of the measurement) the size 10 ferrule will be the correct size. Once you get your measurements take a look at the ferrule sizes both above and below the number and go with the slightly smaller ferrule. It is pretty common on restoration rods to have some build-up of glue that can skew the numbers just a bit. It's always a good idea to measure both the female side of the ferrule and the male side to ensure the sizing is roughly the same.
