Reel Measurements (pun intended)

This is another why don't they just.
Why don't reel manufacturers list their reel dimensions as cubic inches of capacity. The math is pretty simple and it would make it easy to find a comparable reel as opposed to the method now (WF9 and 200yds backing)

That would require them to tell the truth about their reels! And we would be able to compare! I bought a daiwa baitcaster that said it held 170 yards of line and spooled it up to the limit with 110 yards--I dont think it would have held 170 of braid!

You haven't included any of the math. Wouldn't it require backing and flyline manufacturers to provide additional info on their products? Not sure much of this would sink in anyway. I had a conversation with a guide a couple of years ago about the retrieve rate of large arbor reels. I tried to explain that all things being equal my Lamson LP-4 with a 4" spool would reel in line as fast as a large arbor reel with a 4" spool. I was not able to convince the guide.

I know the math our talking about. Takes into consideration spool width, arbor diameter, max capacity diameter, backing diameter, flyline diameter (and changes).

Here's the problem. That represents a perfectly wound spool. Each wrap next to the previous one and each layer containing the same # of turns.....

This does not take into consideration the variability of such parameters.

The equation would start like:

SUM (n=1 to n) (Diam Arbor + 2*Diam backing) * (Width Spool/Diam backing)]
n = number of layers

I'll have to finish this tomorrow, time for hockey

Tomorrow's lesson will start with removing the volume of the flyline then determining the max amount of backing based on the above expression.

i think if the industry just came up with a mathmatical equation, be it the "perfect number" of wraps around, or whatever, atleast if would give a number that can be compared as a constant. Then after the fact you can look at diameter or the spool and arbour, aswell as the depth.

All you need is total area: the spool width x (pi r squared of the spool minus pi r squared of the arbor). Now you have the cubic inch capacity of the spool. This can be used to compare apples to apples with other reels. Exactly how much line fits does not enter into the equation. This would be an accurate tool to compare reel sizes. If every manufacturer did it we would have a easy tool to compare reel sizes and I'm sure after a short time everyone would know that you needed a X cubic inch or centimeter reel for a 9 weight rod. :)

that is how I sized the reel I designed. I took 4 spools with known backing size and amount, then interpolated the volumes.

Freakish but I have a Lam velocity 4.0 that claims to hold around 200+ yds of 30# backing.....the guys at my fly shop spooled it with 350+ yds of 30 lbs micron backing plus a WF10 line.
I find my spinning reels tell a lot of BS when spooling line. Never can handle what they claim

the 200 yards of 30# is probably for regular old dacron, the micron backing is thinner allowing more to be put on
