A comment about the relatively slow retrieve-rate of a centre~pin compared with a fixed-spool reel, by Elton in his Early-morning starts thread set me thinking.......

Multipliers have geared-up drums (spools) and you can get geared-up fly-reels (which are small centre~pins), so why not geared-up large-diameter e.g. 5", 'pins?

You can, they are called multipliers !!

Sorry, couldn't resist that one!

Not sure if they are still available but I had a geared up pin about 50 years ago. Bright green if I remember and very shiny.
Mind you it was no good for trotting, but I did use it for pike fishing.........got stolen with a lot of other tackle!!!!!!!!!

I seem to remember it was made/marketed by Milbro??

Why was it no good for trotting?

Chesters'll probably remember who made it

'Cause the gearing increased the resistance and there was no free spool. Yep, Milbro was the maker. And the line used to get behind the back plate. Mine was blue, you had a choice of colours.

This geared-up fly-reel has a 1.85 : 1 ratio

5" 'pin = 10 inches
fixed-spool reel = 22.8 inches

So it follows that your pin has a drum circumference of 5 inches, and your f/spool gives you a circumference of just under 9.2 inches per revolution.
This tech'ie stuff could become catching.

As someone has said, too much line could give you problems laying the line properly, but how much would be too much when, at speed you get a side build-up which then falls an traps the line under it?

Doh! the pin should be a circumference of 10 inches, I blame the fact that I just popped in whilst cooking Sunday lunch.

Hi Nugg,
Yup, with a centre-pin it's easy ... one turn of the handle is πd .....pi (3.1416) x the measured diameter of the line loaded on the drum. So if the diameter of the line on the drum is say 10 cm, then one turn will retrieve 31.416 cm of line

_________

With a fixed-spool reel, it's the diameter of the spool loaded with line (in my case 3.7 cm) multiplied by pi (3.1416) ..to give the circumference, then multiplied by the number of turns of the rotor per turn of the handle ... this is the gear-ratio (5.1:1 in my case) ... hence a 58 cm retrieval of line per turn of the handle on the fixed-spool, compared with the ungeared, direct centre~pin's 25 cm of line retrieved .... but, with a flick of the finger, you can spin the 'pin at fast revolution, something you can't do with a fixed-spool set-up

Re: 3.7 x Pi

A friend of mine once tried to do this calculation on paper, and three years later he was still trying to write down what Pi was.

;-)

steak and kidney
i always "tell" the difference between fly reels and pins by the amount of handles ,not being a pin user or fluff chucker ,why is there a difference?? seeing both are centerpins albeit fly reels dont have to free spool as the line is on the reel only as a "holder" :confused:
and why dont centerpins have decent drags such as the intrepid super fly :confused:
