The rodbuilder will be able to use the FUJI specifications, which you will find numerous copies on the Rodhouse forum, which indicate a number of rings, a spacing of the rings with respect to the scion, as well as a size of rings.
These specifications are valid, proven, and allow you to build safe and reliable rods, and we recommend them for those who are new to rod assembly.
However, we will be able to overcome some of these constraints and prefer other arrangements, given that these specifications, based on length, obviously can not take into account the action of each rod, see action that the we want to give to a blank, that is to say that we choose a given montage according to the action it will have on the blank, the use that we want to make of the cane, which it too will determine for example a specific handle length so a placement of the first ring adequate, etc ...
To caricature, single-legged micro-rings will find their place on a jig rod, and conversely we will not mount on a vertical rod of 1.90 the reel holder in the same place as on a cane finesse kayack, while the Gross lengths could be comparable and therefore at first sight correspond to the same mounting chart.
Cane mounting allows great freedom, great adaptability to each user and each fishing situation: we can inspire existing canes, correct what we consider to be weak points, we can invent any cannes for its own use and more to be dependent on the modes which impose to practice such type of fishing with such type of length of cane, and sometimes counter-themselves from years to years.
With regard to the rings, the current tendency is to a certain increase of the number of the rings, and thus to a certain ... decrease in their size, points which would favor the sensitivity of the cane, its resonance, the length and the precision of the rings. throws ...
Without being definitive on these points which are for some rather subjective and personal (will find two people agree on the definitions of resonance, sensitivity, etc is the feat), we can however agree on a few bases:
A larger number of rings soften the blanks, and allows the thread to marry its shape better.
Rings smaller and closer to the blank allow the wire to be looser, closer to the blank, more tension, and therefore better to transmit impacts
Smaller rings associated with light blanks induce less weight and therefore increased resonance; We will remember to caricature the image of a fisherman with a wooden cane of 6 kilos and another with a carbon rod of 70 grams, it seems obvious that one of the possible axes in the search for sound of a cane passes through a lightening of the whole, and that the rings participate in this set: to equal material of smaller rings weigh less heavy than large.
Conversely too many rings will bridle the thread during throwing by increasing the friction surfaces, too much change the action of the blank, and rings too small will badly hurt the knot to pass and weaken will launch after to throw to the breakage: everything is a matter of compromise and to study what are the needs on a given cane.
