Snood length on pulley rig

Hi,

I have been making pulley rigs for use with an impact lead by making the snood length to exactly match up with the impact lead clip when the main rig body is tight against the swivel that attaches to the snood. I have done this on the basis that the strain of casting is then applied 100% through the main rig body.

Looking on youtube all the instructions don't do it this way - the snood is simply shorter than the main body and on casting, the running pulley swivel is positioned half way (at the folding point) of the main rig plus the snood - not hard against the swivel that attaches to the snood.

I have a rudimentary understanding of physics which tells me that the youtube methods are applying only 50% of the casting strain down the main body and 50% down the snood (unless one stretches more than the other).

Is it normal to do it the youtube way? What do you do and have you had crack-offs doing it the youtube way?

Cheers,

Rich

Hiya Rich,
Sounds like i build mine the way you've seen on youtube.
I use a minimum of 80lb line for my rig body & use a 60lb hooklength (if you're not targeting small stuff there's no need for a lighter hooklength)- a doddle to tie, no worries about snood lengths or crimps/stops & easy to replace a knackered hook.
As regards snood length when i tie my rigs anything around 3ft or so (if i want a longer snood i use an up & over rig.
Rick;)

A lot of pulley snoods seem to be fairly hefty if not the same as the weight section. Makes them less tangly I think.

If one used 5lb and 80lb then yes we wouldn't have 160lb of total BS between swivel and the lead when clipped up. (Remember, there are weaker points in the chain than the double line of the pulley).

And the knots / hooks etc reduce this anyway. All comes down to how much force the caster generates and the weight in the end. Most setups I've seen have plenty of safety factor.

I always make my pulley rigs with the hook length about 3 inches shorter than the main body. This ensures that as long as the bait doesn't weigh more than the lead then it will sit nicely either on an impact shield or impact lead for casting.
Also generally speaking when using a pulley rig I am targeting the bigger species, hence my hook length material matches this, for example my rig body is made of 80lb mono and hook lengths vary from 40lb to 80lb depending upon target species, hook size, bait size and rig length and what I am trying to achieve etc.
Generally speaking again I like my rigs to be 40 inch bodies with around a 3 foot hook length, these dimensions seem to work best for me when fishing deep water sea lochs, you might find that if you are fishing the Bristol Channel or Chesil etc you will have to adjust your dimensions to suit you best depending upon tide strength, ground conditions etc, etc.

Spot on, I like to start long so 3 foot and maybe a bit is perfect for me. Deep hooked fish... (Doggies usualy) just cut the snood as short as possible and tie on a fresh hook. The fish will spit the hook eventually.

I find that the strain is not evenly applied. That having the snood shorter allows the main rig body to come up, over, and down some distance. I use lighter snood materials that would never hold up to the stress of the cast, yet they survive. So maybe the fact that the main rig comes down a ways prevents over stressing the snood. Although I’m sure one could design a rig that would snap the snood, I see no need to use an unnecessarily heavy snood.

A shortened pulley rig really flies well. I like mine to be less than two feet long when engaged/cast ready. Most seem to prefer longer lengths, for presentation purposes I imagine. Good luck

Is it not true if you have a simple pulley system with an upwards force in terms of the cast, then the opposing force imparted on each side of the trace be equal and 1/2 of the total. So technically using a 30lb snood clipped down with a 6oz lead should be fine?

Not sure if there really is a halving of the stress, as I mentioned. Maybe so, maybe not. I know that I use a very heavy main rig body on my pulleys, and usually 20 lb on my snoods. I suspect that the stress is not equalized. Surely if it were I would experience separations. I do add a twisted loop to the end of the rig body, and maybe that is acting to absorb the stress, like a spring.

Do you experience failures ?

And how do you work out 2x 30 lb don’t give you 60 when returned to same point it started from,give or take the crease in the line/ knots that is running through the clip / swivel or pulley bead which will knock down the b/s a small amount.if what your saying is true if you incorporate a plastic impact shield into the pulley rig and as you say doubling up don’t give you around double,your 80lb leader an average snood b/s, what force is applied to the impact shield,beacause i doubt imo the shield would withstand a 7oz on a proper power cast.

Havent experienced any yet. Im the same, my main rig body to the sinker is at least 60lb bs and snoods between 20-30 depending on the lead weight. I agree and assume the stresses will not be equal due to the two line ratings having different stretch factors aswell as slight bending of the hook. I would think the rig body would take a majority of the stress as it requires more force to stretch.

one side would be weaker or stretch more than the other then the result would slip and reduce the length around the pulley / pivot and break if the maximum stretch was exceeded for that line , if in doubt tie one up with braid and see if you snap something , 2 lots of 30 on a pulley dont make an overall 60 !!!!
never have the rig body lower bs than the leader , i normally have my snood length about 10mm or less shorter than the length required to clip in any device , coupled with a few hardish rubber beads at the pulley end , this generally has enough elasticity in the set up to sort out any dodgy casting releases ect and also to stop any excess forces on the clip down system which can cause premature release
Even so If that was the case, surely there will not be a need to use a snood the same bs of the rig body. I do use a heavy main rig body for safety reasons, theoretically 30+30 should be ok but then knot strenght and potential damage to line makes for some uncertainty.

i dont use a snood the same bs as the rig body normally .5 rather than .8 for the rig body
I dont rely on the snood providing ANY strength to my overall set up , thats the rig bodys job
30+30 on a pully dont equall 60

Spot on for any kind of fishing regarding the line.
Why would your snood be thicker than your main line?
only for abrasion resistance from teeth I imagine, tangling perhaps, I got congered a few times at Chesil so went to .8, normal specimen ray type fishing .5 is normally fine for me, just keep check on it after a capture

The way you describe is the way Dave Docwra describes the rig in his booklet published years ago (see attached). It allows you to use a light snood which can be useful if the fish are shy or you are fishing in rocks and the hook gets stuck.
