Hi all,

I'm not a frequent contributor on the forums, but I've found my fair share of good advice and assistance here. To that end, I'm happy to give back to this community in a way that I hope will be useful.

I've been corresponding with Chris Carlin of Far North Rod Rodsmiths, and with his expressed permission I've made his guide calculator available online.

You can find the guide calculator at http://guidecalculat...oattraders.com/

Why?
Simple. I'm not always near my PC, but I always have my smartphone or tablet near by. With this web app you can use the calculator anywhere. You don't need to download anything. If you're a Mac user, you don't have to install Wine or any emulation software. All you need is a bookmark in your favorite browser.

More importantly, This is my way of saying "Thanks" to a you all who are keeping beauty in the sport of (fly) fishing!

What?
It's a simple web app. It's designed with two versions: one for desktop and one for mobile devices. It'll look more like an iOS app on your smartphone or tablet, and like a traditional website on your desktop browser. The calculator uses the same algorithm for both versions based on Dale Clemen's and Jeffrey Baehre's spacing equations.

Improvements?
Naturally I'm not interested in delivering something and walking away. My hope is that you (the community at large) will provide suggestions and feedback to make the tool better over time. I'm offering to consider any and all suggestions which would improve the tool and incorporate them into the tool (or perhaps make additional tools). Since it's online, updates become immediately available.

---------------------

There you have it - I hope you find it helpful. And please, do take me up on the offer to keep it up to date so it meets your needs.


Cheers!

I pasted a a typo in the link. Try it again - I've fixed my post with the correct URL.

Same as above - I had a typo in the original link. It's fixed now

This looks really good. Like the simplicity of this one. I've been using the hexrod Wayne Cattanach calculator (http://hexrod.net/Guide/guideN.html), like the ease of this one but like the index guide concept incorporating the index guide as it lets you work with where the ferules lie.

With this in mind there is one improvement suggestion I have. Input the number of rod pieces and use that to show where the ferrules fall in relation to the guides. Probably need to include a overlap depth on the male ferrule or section length as well for accuracy.

Here's pretty much a layout of what I'm thinking

Example for a 9' 6" foot 4 piece. Happened to have one close and the math works out nice.
Each piece is 30" long
Seat depth is 2"
Ferrules from tip fall at 30", 58", 86"
Math with overlap : 114/4 = 28.5 - 2(set depth)/4 = 28" for first three sections and 28+2 = 30" for tip.
or with section length: 114 - 30 = 84/3 = 28

Output would be something like
CODE

# Inches from Double Foot Single Foot
Tip Top (Snake)
1. 4 1/2 1 5 mm
2. 9 5/8 1 5 mm
3. 15 7/16 2 5.5 mm
4. 21 7/8 2 5.5 mm
5. 28 15/16 2 5.5 mm
---------------- Ferrule 1 at 30" -------------------
6. 36 11/16 3 6 mm
7. 45 3 6 mm
8. 54 1/16 3 6 mm
----------------- Ferrule 2 at 58" -------------------
9. 63 11/16 4 7 mm
10. 74 5 8 mm
11. 85 12 12 mm
----------------- Ferrule 3 at 86" -------------------

This is just the programmer in me at work... but I do think it would be really helpful when tweaking the layout to have the ferrule stations included.

Thanks - Nathan

I follow it for spacing, but see absolutely no reason for that many different guide sizes as it suggests

I'm with Ron
I test on same blank 1(x3) 2(x3) 3(x2) and 1(x6) 2(x1) 3(x1) and saw no difference except aesthetic and weight whistling1.gif

You're the third person to mention the Cattanach system. I need to familiarize myself with how the calculations work. If anyone can explain it to me, I can code it up in no time. I'd be happy to put both calculators online! If you're aware of where I can find a sample of the math, point me to it!

Great job Tyler! I haven't messed around too much but it looks like it works perfect. clapping.gif

My best guess for the Cattanach system is as follows:

Initial variables:
# of Guides (NG)
Index Guide Number (IG)
Distance of index guide from tip top in Inches (ID)
Guide Spacing Increment in Inches (GS)

For our example, lets use the following values for these variables:
NG = 9
IG = 7
ID = 50
GS = .5625 (9/16)

In short, the idea is to increase the space between the guides by GS. To do this we first need a guide number and a delta spacing to start from.

To figure this we'll use the following formula:

SV = ( ID - .5(IG*(IG-1)) * GS ) / IG

This basically takes the number of incremental spacings (GS) we need between the tip and the index guide and figures the total in inches, subtracts that number from the total distance to the index guide (ID) and divides the whole shebang by the index guide number (IG). The result is SV or the Starting Value which is the difference in distance between the tip top (0") and the first guide (SV).

SV = ( 50 - .5(7*(7-1)) * .5625 ) / 7 = 5 7/16


Starting at Guide # 1 we enter the value for SV in the Delta column:

Guide # : Delta
1 : 5 7/16

Now we add SV to that number to get the second delta:

2 : [5 7/16 + 9/16 =] 6

and continue until we have reached the total number of guides:
1 : 5 7/16
2 : 6
3 : 6 9/16
4 : 7 1/4
5 : 7 11/16
6 : 8 1/4
7 : 8 13/16
8 : 9 3/8
9 : 9 15/16

Now, we begin again with a third column for the actual Guide Spacing and enter SV in the first row:

Guide # : Delta : Spacing
1 : 5 7/16 : 5 7/16

Take the spacing number, add it to the Delta and you have your spacing for the 2nd guide

2 : 6 : [5 7/16 + 5 7/16 =] 11 1/2

Continue until we reach the total number of guides, and the result is your finished guide spacing chart.

1 : 5 7/16 : 5 7/16
2 : 6 : 11 1/2
3 : 6 3/8 : 18 1/16
4 : 7 1/4 : 25 3/16
5 : 7 11/16 : 32 3/4
6 : 8 1/4 : 41 3/16
7 : 8 13/16 : 50
8 : 9 3/8 : 59 3/8
9 : 9 15/16 : 69 3/8


You will also find some slight discrepancies between the above and the online version of Wayne's program. I'm assuming these are rounding errors of some sort as the differences are small.
