Knot wars apparatus

[clh121787]

So. I want to build some thing. Budget friendly that I can test knots head to head. So far I'm thinking a frame  with a crank on one end with anti reverse gear and catch, similar to the winch on a boat trailer. With a fixed eye on one end or something.  Then get a length of line tie two different knots to some hooks (with clipped points for safety) hook them to the crank and the anchored eye and start cranking.... There's has got to be someone more creative than I. Input needed please. GO!

Here's one idea.

I often compare the knot-strength of two different knots. It's a very basal task that requires no skill

and no special apparatus other than one heavy-wire barrel swivel

 

Simply tie the challenged knot to one of the swivel rings, then tie the challenger knot

to the opposite swivel ring.  Now pull the line ends apart until one of the two knots explodes.

It's immaterial whether you use manual or mechanical force, and the numerical pressure

involved is also immaterial (you're simply looking for the winning knot) Repeat this simple exercise

until you are fully satisfied that you've determined which knot is stronger.

In this same manner, you're also able to compare dry or wet strength,

as well as the ability to compare the breaking strength of different lines, it's fail safe.

If every fisherman performed this simple comparison there would be more answers than questions.

Hello

 

I noticed your post about testing knot strength.

I have seen the Knot Wars episodes and it looks as if they are using a servo motor turning a cam or moment arm and recording the torque required to break the knot.

 

Servo motors can be used in conjunction with a gearbox inexpensively.

The current of the motor relates directly to the torque required to break the knot.

Also servos are very repeatable.

 

This is an example of a linear servo actuator and controller that can be purchased very inexpensively

 

 

Hope this helps

In case anyone was curious, the Polymer knot took top prize in commode wars tonight.
