Mike cc had us over for a rod building class 2 winters ago. About 2 weeks ago with my upcoming vacation I'd decided that would treat myself to a new rod. Being under the gun time wise it would be unfair to ask a builder to have it ready for me in 5 days. That being said I started doing some research and came up with the following. Credit goes to Sargeant S. online I forget where it was but it was a distance casting forum I stumbled across. I've prepared a similar document to the one which helped me. Scotty and Mike Cc were also a big help.
The document:
The prototypical spacings and the formula for adjusting them because of length / reel seat differences is found on page 41 of the Fuji catalog.
http://www.fujitackle.com/catalog/imgs/36_41.pdf
Looking at page 41 we will use the bottom rod in the third group as our prototype. It has seven guides plus the tip.
Blank length -- 425cm
Butt to center of reel seat. 88cm
center of reel seat to gatherer guide -- 120cm
Space on rod that has guides = 217cm
Guide spacing - tip down
Tiptop to first guide -- 17cm
first to second -- 20cm
second to third -- 25cm
third to fourth -- 28cm
fourth to fifth -- 33cm
fifth to sixth -- 44cm
sixth to seventh (gatherer) -- 50cm
17 + 20 + 25 + 28 + 33 + 44 + 50 = 217cm
217 is value "A" in the Fuji formula.
Again, formula is found on page 31 at:http://www.fujitackle.com/catalog/imgs/36_41.pdf
New layout . . .
New butt length & keeping reel seat to gathering guide spacing to Fuji recommended 120cm:
Butt to center of reel seat. 68.58cm
Center of reel seat to gatherer guide -- 120cm
We must now solve for the remaining rod which will have guides placed on it. . .
(Total length of rod =132.2 inches or 335.78 centimeters)
Formula:
Total Length of rod (minus) Center of reel seat to gatherer guide (minus)Butt to center of reel seat= B in Fuji formula
So assuming the following:
335.78-120-68.58=147.2
147.2 is “B” in Fuji’s formula
B" divided by "A" gives us the ratio to grow the spacing: 147.2 / 217 = 0.678
Tip to first guide – 11.52cm or 4.5inches
first to second – 13.56cm or 5.5 inches
second to third – 16.95cm or 6.5 inches
third to fourth – 18.984cm or 7.5 inches
fourth to fifth – 22.374cm or 9.0 inches
fifth to sixth – 29.832cm or 11.5 inches
sixth to seventh (gatherer) – 33.9 or 13.5 inches
11.52 + 13.56 + 16.95 + 18.98 + 22.37 + 29.832 + 33.9 = 147.112 cm or 57.95 inches (58)
Suggested spacing, still needs deflection testing etc.
Butt to reel seat 68.58 cm
Center of reel seat to Gathering guide 120cm
Portion of rod with no guides on it: 188.68
Portion of rod with uides on it: 147.112cm
