How many independent free floating silicon disks should the ideal  low-start-up-inertia fly reel disk drag  system have and does the requirement differ depending  on whether or not the reel is CNC machined from high grade aerospace aloominim or standard bar-stock aluminum?

How many independent free floating silicon disks should the ideal  low-start-up-inertia fly reel disk drag  system have and does the requirement differ depending  on whether or not the reel is CNC machined from high grade aerospace aloominim or standard bar-stock aluminum?

The number of independent free floating silicon discs should be lesser for a reel machined from high grade aerospace aloominim, as the resultant reel is lighter and thus has less inertia to start with. However the extra strength of aerospace grade metal allows less to be used in the design (for the same strength) thus the reel can have a greater number of nicely designed holes in it. This reduces the space available to fit the floating discs. BUT to provide the same amount of drag, the total surface area of the discs must be maintained. So in the end, a greater number of (smaller) discs are required on an aerospace grade reel.
These technical requirements are beyond the engineering knowledge of the majority of wild fisherpersons (you're no gonnae sack me for sexism) so let me put it in simple terms for you. And in three simple steps.
1) Look at the box the reel comes in. Was the reel machined from (A) old coke cans or bits of (B)Concorde?
2) Does the drag (A) click, or (B) have an independent free floating silicon disc system?
Add ?100 to the price of the reel for each questions answered with option (B) above.
3) Count the discs, add ?25 to the price of the reel for each disc.
Simples.

Some interesting and very well thought out comments there. One small problem that immediately springs to mind is that the ideal number of 42 disks can take up rather a lot of space and that  by substituting the  silicon disks with carbon fiber disks, similar coefficients of friction values might be obtained with fewer than 42. Obviously some of the disks would have to have their fibers arranged transversely and some radially. The total number of disks required and the proportion of transversely  and radially  arranged disks is difficult to calculate, the actual numbers being the roots of a quadratic equation that has no  real roots. The choice of high grade aerospace aloominim or standard bar-stock aluminum further complicates this. In your opinion should these numbers be approximated by use of the Newton?Raphson method, or would just taking a wild guess be enough?

Wild guess should do it, but to refine your resolution of insoluble quadratics, please understand the basic principle of ADLAW. (the first law of marketing). This defines the required four possible variants and interpolates their quadratic relationship. They are-
Mugs
Price
Pseudo Engineering and Science Speak
Brand Perception
The four variants are set such that the functional outcome of the process tends towards ?P=?M where P= Profit and M=Maximum.
Conflating Haresear's wise words and my qualified and experienced post- from the base of a ?10 Okuma plastic reel- a price of-
?10 (base price)+?100 (disc drag)+?0(standard aloominim)+(?25x42)(number of discs)= ?1,160 at a probable FEC (That's "full economic cost" numpties!) to the manufacturer of around ?1.26.
However the variant "Mugs" cannot exceed the median of the standard distribution curve (0.5). Thus the price of the optimum reel is ?580.

You've missed the obvious here lads: remember that a sintrix is a matrix of nano-tubes intergrated by i, therefore, by substitution, the answer to the number required is simply to discover that number whose square is -42.

Right back to work.

[Wildfisher]

That's  fair enough Malcolm, but it does place severe limitations on hole pattern choice. We mustn?t  forget that hole density is major factor in final weight calculations or  TRM (total reel mass) and directly relates to start-up inertia and therefore disk material choice. It?s essential  to get the type of hole, it?s position relative to adjacent holes  and the overall hole pattern exactly right. No two holes are ever the same and to simply integrate the nano-tubes matrix   without taking this into account will undoubtedly have an adverse effect on the rotational aerodynamics of the spool and could result in break-offs in bigger fish.

And, of course, you have to leave space for the manufacturer's badge on the reel cage. Assuming the same font size and no logo. You have to include the following factors to hole size, and position
Sage=4
Loop=4
Orvis=5
Hardy=5
Greys=5
Sonik=5
Leeda=5
Airflow=6
Scierra=6
Wychwood=8
Guideline=9
Stillwater=10
Ron Thompson= 12(don't forget the space)
