Torque Needed to Remove Fish Scales

03/13/2017 2:17 PM

‏what should be the torque needed to remove the scales from the fish? And the formula used to find the torque?

That should depend on the kettle of fish you plan to cook...

Shark scales are one thing, red fish scales are quite another. Dock scales generally do not respond well at all to torque, especially when loaded with a really heavy tuna.

Talking about Trolls fishing, why are you still here? You've been booted off three times before. You're like my ex-wife on Every Ready batteries®(no endorsement intended), that keeps going and going with nothing to say. Can't take a hint, huh?

Nah, his name is Billy, but I call him "Buildy". Usually he just barks around and lets the victim fall out. Sort of like a drill Sergeant. Other dog named Sergeant, but he has such a shrill bark, he is a weapons platform unto himself.

2 dogs myself. One called Caution. The other called Cigarette. (poor thing has no legs).

I take Cigarette for a drag each day while exercising Caution at the same time.

My dog is named "Smiley" for her friendly and engaging attitude.

Smiley says "Hi, I hope you have good taste."

No, I distinctly heard her say, "Hi, I hope you taste good."

Is that a terrier, or is that a blue heeler? Wait a minute, hold the phone, that is Chihuahua!

The most prolific ankle biter in the Western Hemisphere! Known to hang out near urban taco stands.

She's not crazy, we had her tested.

We did a genetic test and she is 3/8 Chihuahua, 1/4 Jack Russell terrier and 3/8 mutt.

We call her a Chimutttrier, a new and important designer breed. We got her partly because she looks just like a rat terrier we used to have.

Depends on the species of fish. Cat fish would take 0 torque.

Of course they do. Just as buffalo have wings. Try plucking a flying squirrel or de-scaling a dragon fish. You have not lived sir, you would die in the wild outback of national park. The easiest creature to de-scale is a kettle.

What the heck are you talking about? Fish scaling, torque???? This is about cleaning fish, not mechanical engineering. Scrape the damn thing until the scales are gone, who cares about the torque to remove them. Every fish species will need a different amount of energy to remove their scales.

Skin them like I do, and you won't have to worry about the torque to remove their scales.

This is the second similar post by the same person. Last one involved proper angle to de-scale. I suspect we have an attempt at inventing the next "big thing" for TV infomercials. Trouble is, there seems to be a number of them available already. Filleting is still better.

Re: Fish scaling

I'll play. The torque would be the force needed to remove the scales times the moment arm from the point at which the fish is held stationary (the pivot point), and therefore would be a function of the size of the fish and how tightly its scales are attached (the type of fish).

Are you writing instructions for engineers on how to clean a fish?

That's why they make trolling motors-go slow enough not to outrun the trolls.

T = F * r * sin(theta) *Bd - Ce/EG

T = torque

F = linear force

r = distance measured from the axis of rotation to where the linear force is applied

theta = the angle between F and r

Bd = blade depth

Ce = Cutting edge

EG = Elbow Grease.

NOTE: do not attempt this unless supervised by an adult. Do not attempt this at home.

I tried this formula on a mountain. I could not scale that at all.

It depends on how many scales you are trying to remove at a time, and on the species of fish.

Re: Torque Needed to Remove Fish Scales

Depends on the radius of the scaling cylinder.

Clearly if the radius is 1 foot then you will require 24 times as much torque as you would if the radius was ½ and inch.

Type, age, size of fish...

What you need to know first is the linear force required to pull out one scale. Multiply that by the number of scales you expect to be removing at any instant in time. Then multiply by the radius to get the required torque. Double that at the very least to get a reliable solution.
