Product Description

Note: the last photo is an example of deep blue & clear coating on Payne Replicas.
These ferrules are  our  premium line of nickel silver ferrules, crafted by the masters at CSE and widely recognized as the finest available. Appropriately named Super Swiss, this ferrule system utilizes a time-proven design that needs no introduction.

  • Standard Super Swiss ferrules are typically used for 2 pc. rods
  • Truncated Super Swiss ferrules are typically used for 3 pc. rods
  • Step-down Super Swiss ferrules best complement the system used by well-known rodmakers like H.L. Leonard, E.F. Payne, F.E. Thomas, & others. These ferrules are particularly useful for general restoration jobs where precise replication of a maker’s ferrule set is not necessary.

Males are 0.001″ oversize and require minimal lapping.

  • Whole set (WS) indicates one female & two males.
  • Half Set (HS) indicates one female, one male.
  • Female Only (F).
  • Male only (M).


For those of you who are itching to know just how big a step do “step down” ferrules take, here’s an email response I wrote on that very subject:

I grabbed a Nominal 15/64 Step Down and a Nominal 15/64 Restoration Step Down from the bins.  I’ll break out the specs, which may help to clear things up.  Truly, not trying to be salesy, it may be worth buying one set in a common size (13, 14, or 15) as a reference.

15/64 Step Down Ferrule

Female ID where it fits over the ferrule station: ~0.232″ (14.84/64)

Female ID where the male ferrule fits: ~0.231″ (14.78/64)

(this female is essentially a straight piece of tubing with a water seal soldered inside and a welt soldered on one end, with the other end tapered slightly then slit for tabs)

Male ID where it laps over the ferrule station at its MAX, or shoulder, ID: ~0.232″ (14.84/64)

(there will be a smaller ID inside tubing that forms the stepped down male slide, approximately equal to 13/64)

Male OD on the slide, which must be lapped down to fit into the female ID: ~0.234″ (14.97/64)

There are two ways of looking at this “step”….

1) There is, from one perspective, no actual step because the maximum ID of both the male and female ferrule where they fit onto the bamboo at the ferrule station is almost 15/64 and you’d need to build your blank to be just a hair larger than this spec at BOTH the butt of the tip section and the tip of the butt section so you can turn each down to fit snugly into the ferrules at their max ID.  Under this view, the ‘step’ of the Step Down Ferrule is more of an aesthetic step down and less of a functional one when crafting the bare blank.

2) There is another camp that looks at two portions of the male ferrule and say it steps down from a max OD on the skirt of ~0.272″ (17.4/64) down to a minimum OD on the male slide of ~0.234″ (14.97/64) and maybe they’d call that a 2/64 jump, but it’s NOT a 2/64 jump across the ferrule station, just a jump of that size relative to the max/min OD on the male ferrule.

These Step Down ferrules are commonly said to have a 1/64 drop, but the more I sit here typing and thinking about the specs of the various parts, I think I’m leaning toward saying they have no drop.  This seems sort of counter-intuitive when you look at the parts and clearly see the stepped male, but if you hold the male and female ferrule so that you’re looking into the tabbed end of each – the bore where each ferrule fits over the ferrule station – you’ll see that the two bores are visually identical.


15/64 Restoration Step Down Ferrule

Female MAX ID at the skirt where it fits over the ferrule station: ~0.264″ (16.89/64)

Female ID where the male ferrule fits: ~0.231″ (14.78/64)

Male ID where it laps over the ferrule station at its MAX, or shoulder, ID: ~0.232″ (14.84/64)

Male OD on the slide, which must be lapped down to fit into the female ID: ~0.234″ (14.97/64)

This has the true 2/64 jump across the ferrule station.  Look at the Max ID on the female (16.89/64) vs. the Max ID on the male ferrule (14.84/64) and you can see that’s almost a perfect 2/64 leap across the juncture.  In other words, when you build the blank, you’d want the butt end of the tip section to be a bit over 15/64, then that would be turned down, in stepped fashion, to fit into the male ferrule…and you’d want the tip end of the butt section built out to 17/64 so you could turn that down, again in stepped fashion, to fit the female ferrule.  It’s this jump that makes me say that Restoration Step Down Ferrules have the 2/64 jump.

If you look at the bore of these two parts, male and female, your eye will instantly register the fact that there is a discernible leap up from the bore of the male to the bore of the female.

I really hope all this helps.  If it does, let me know and I’ll probably post it onto the website pages.  If not, then I’m not sure how better to explain it and I’m back to suggesting you buy a set or two (i.e., one of each type in the same nominal size) so you can look at the construction and see how one sort has essentially no jump while the other has a rather large jump.
