This S-O Tool Confuses Me.

[Bolster]

SNap-on TZ-1. How does it work?

 

[chadster1]

Its one of those things that you might never use but if you do ever run into the situation where you have to get around a corner, you will be glad you have it.

 

[Bull]

My puny brain cannot fully grasp its purpose. I would hazard a guess that it is for accessing concealed/limited access fastener though, right?

 

[Bruce Lancaster]

Standard quantum connector. The drive exists simultaneously in multiple orientations and dimensions.

 

[daveroy]

Turns your standard extension into a 'static' ratchet! (just a guess!)

Think 'mini breaker bar'

 

[atari]

Im guessing breaker bar and crows foot around an obstacle? It makes my brain hurt.

Description:
1/4" drive extension connector adds versatility to extensions, breaker bars, ratchets and crowfoot wrenches. Connect one or more tools together to make different shapes, lengths and angles to easily reach limited access fasteners. Use in automotive, aircraft, marine, heavy truck, plumbing and manufacturing applications.

Snap-On screwed up a bunch of 1 inch extentions and had to create a market for it, lol

 

[Bolster]

I fear my reputation is hurting me here, I wasn't trying to be funny. (Bruce wins the cake for levity, though.) Seriously, I'd like to hear from someone who has used one, who can explain to me what the usage is.

All the further my brain can process it, is that it's sort of like a t-handle, only a t-handle with the drive that's slid all the way to the end. But I read you often use these in pairs, and that's where my brain explodes.

Is it possible that M.C. Escher designed this tool for SO?

 

[jpoe]

Standard quantum connector. The drive exists simultaneously in multiple orientations and dimensions.

That is funny.

 

[superautobacs]

This type of adaptor was discussed in this thread

Could somone explain how you would use the type that mrshaun posted? I can't figure it out.

[Referring to the TZ-1]

stick any length extension into adapter, then add a socket....or add another extension to it, another adapter, another extention, another adaptor..... have some fun and be creative with it bascially.

What SO charges for those things are ridiculous.

(I got a pair that's made in Taiwan for less than half price with better fit and finish.)

 

[Bruce Lancaster]

It COULD be used with a vertical breaker bar motivated by a crossbar as a kind of crow's foot substitute. I'm guessing that Snap-on just did a study analyzing available arrangements of square drive pins and holes, and moved to fill an empty niche for the people who just bought the grand luxus every-tool-we-make-in-a-box-bigger-than your house set who instictively purchase anything else that might come along.

Well hell, why didn't you say so? That's good enough reason for me to buy one, then!

Why buy just one? You really need at least two of them.

Ok someone explain to me the torque calculations for that second picture by SuperAuto...

 

[atari]

I was wondering if anyone else noticed that. I raised an eyebrow.

 

[Bruce Lancaster]

Maybe they are headed into marketing high end toys...for a younger crowd than us, I mean.
Imagine a cardboard tube with 50 0f these things and a huge pile of various length extensions. A tinker-toy set for baby gearheads with LARGE allowances, and when you send in the guarantee coupon, the kid's address goes to the local Snap-on guy who will appreciate the income stream of an ever expanding set!

 

[Skyline]

Ok someone explain to me the torque calculations for that second picture by SuperAuto...

Looks like a pair of these would be a good substitute for a torque adapter in certain cercumstances like this...assuming you could figure the proper torque like you said. But if it were not for the need to measure torque, I would think a box end wrench would be more convenient to tighten the bolts shown on that motorcycle engine.

 

[DavidB]

Ok someone explain to me the torque calculations for that second picture by SuperAuto...

If he's pulling/pushing on the torque wrench perpendicular to the handle (like you're supposed to) it's the same torque. Torque can be defined as the perpindicular distance between the force vector and the torque vector. The perpendicular distance hasn't increased with that extension setup.

For example, say it takes 2 pounds of pushing on a door at some spot to open it. If you push on the same spot with a stick from 2 feet back would it take any more force? No, not if you're still perpendicular to the door.

Another example might be that you and your exact twin are on a teeter totter. It's perfectly balanced and not moving. If both of you go get ladders and sit on top of them on the teeter totter it will still balance. Same principle. Both of your weights are still the same perindicular distance from the rotation vector.

But since you asked for calculations here ya go:

Say you have a force on your torque wrench of 10 pound acting on it (positive x direction). Your torque wrench has a handle that is 12 inches long (extending in the negative y direction). The nut is at the origin of the axis system.

Torque= r x F
r is the vector from the center of rotation to the force vector
F is the force vector

Since you're pushing with 10 pounds in the x direction F=(10,0,0)

For your non perpendicular extension:
The place where you're pushing is straight "down" 12 inches so r=(0,-12,0)
T=(0,-12,0)x(10,0,0)=(0,0,120) aka 120 in-lb

With a 5 inch perpendicular extension:
Now your handle is "down" 12 inches and "forward" 5 inches.
T=(5,-12,0)x(10,0,0)=(0,0,120) aka 120 in-lb

Or your handle is "down" 12 inches and "back" 5 inches.
T=(-5,-12,0)x(10,0,0)=(0,0,120) aka 120 in-lb

Now if the extension is not perpindicular to the direction you're pushing then it does change the torque. The most extreme case being it's in the same direction as your torque wrench.

I think that's about enough nerd for one post...

 

[anyheck]

If used in this fashion (90-degree angle), there is no calculation, the torque is as specified on the wrench.

 

[comedyman809]

kind of reminds me of this..........

[mjozefow]

It is rather simple to understand once you drop the notion that a drive tool should rotate about it's longitudinal axis. It is NOT a u-joint. Once you get that, it is easy as pie.



It makes one of these:

 

[Strouty]

I want a video of the thing in action, it is still making my head hurt. I can see using it as a breaker bar or with one of those ratchet head adapters, but wouldn't it take up 200' of space if you start turning a ratchet with two 90s on it? Baffling, I also have never used a crow foot wrench, but I understand how that works.

Gun control for stupid people, I still don't understand all the workings of that adapter!

 

[shotgunfatcat]

Gun control for stupid people, I still don't understand all the workings of that adapter!

In my eyes, why would you even need a ratchet on it? I don't get it either, besides having one funky wrench made of a bunch of odd parts.

im a "big" gearhead and that sounds awesome... going on my list

 

[toolfreak]

I took a 2" extension, heated and bent it to do basically what this tool is for. It was for a hydraulic pump that I had a problem finding something to get in there and it was the perfect solution. THat being said, I haven't used it since.

 

[Bruce Lancaster]

"....Once you get that, it is easy as pie."

Yes. It is a 90 degree chunk of metal. Some of the uses shown above seem to assume that it is some sort of miracle 90 degree gear drive hiding within a tiny secret compartment in there somewhere.

 

[mrshaun]

Why buy just one? You really need at least two of them.

if you are an apache mechanic then you need two and it saves you about an hours time getting to the orange seal.
I have sold quite a few of these.

 

[wreckercologist]

They would be quite handy when used with one of these:

Actually that tool was a tech designed tool. It was in one of S-O's magazines a couple of years ago trying to show that S-O really would buy your idea. As shown in an earlier picture you get a couple of them and get around obstructions.

[rayzor32]

you can use them as crowsfoots, they can go flying if used as breaker bar though. Like said before u rarely need them but they are handy when ur a pinch
