I’ve followed this excellent forum for some time and it has given me much knowledge and pleasure. Hence, hopefully I can contribute to this discussion.
My understanding of the notation on the Sage S-glass blanks is as follows, and it correlates mostly with what is mentioned in previous posts.
B(blank) : Line weight/power : Length : Material : Type of rod.
In this case, Blank (if there is a B before the numbers) : 2 : 6’6” : S-glass : Spinning
If the power is the same as for my 7 footer below, and in the Sage 1986 catalogue for graphite spinning blanks, it is for casting lure weights of 1/8 to ½ oz. As the power value is relative to type and length of rod, it might be a bit lighter, say up to 3/8 oz, but that is only a guess on my part. This blank will make a very nice rod.
Alas, the 1986 catalogue only describes graphite. It would be interesting to see a catalogue from the years they produced S-glass rods, circa 1981-1983? I’ve searched the web, but without luck.
The above is in line with the data on the blanks I built rods on in the 80s, which may be of interest as a reference in this thread.
B 159 SSP Blank : -1/4 oz. : 5’9” : S-glass : Spinning. 2-piece.
(chform has a recent thread on this kind of blank built as a fly rod)
B 270 SSP Blank : 1/8-1/2 oz. : 7’0” : S-glass : Spinning. 2-piece.
B 486 SSH Blank : 3/8-1 ½ oz. : 8’6” : S-glass : Steelhead. 2-piece.
B 476 SFL Blank : AFTM 4 : 7’6” : S-glass : Fly. 2-piece.
B 686 SFL Blank : AFTM 6 : 8’6” : S-glass : Fly. 2-piece.
I think the number of sections, if other than 2, is showed by adding, for example, “-3” or “-4” to the notation.
