Well you had better be quick because this thread will die in a couple of weeks time !!!!

I will try to get the video up very soon but am currently very busy with our main business. When I arrived at my office today we had just under six hundred e-mails and many orders for prop wrenches and other products (Thank You). All but six stated they were certain we are correct! We will see.
My home is located in the mountains above beautiful Redlands California and we have an over abundance of very large, fat juicy CROWS on my property. Should you few nay-sayers wish, I will save some for you to help make the eating easier. Regards All, Allan

Guess that seals the deal for me. I was going to send my nosewheel to Allan for his bearing mod.

But with this kind of attitude, which is made entirely OUTSIDE of the spirit of education and recreation, I will no longer be ordering anything from him. I wish you luck in your business, Allan. A little humility and an open mind will go a long way toward not losing more customers in the future.

So internally it's a torque wrench with a small fixed length extension.

This is true. And, because the internal pivot is very close to the head, there is a big error from shortening the handle, and a fairly small error for extending it.
With a wrench extension, the correction gets closer to 1.0 as the torque wrench gets longer.

The equation has a variable that represents the length of the torque wrench. The argument to support the original claim is that we can eliminate this variable by the choice of our measuring units. I submit that this idea would get you a failing grade on any high school physics test.

Or an M.I.T. physics test!

To sell a product, you need exposure. To get exposure on this site, you must create controversy.

Anyone that has ever owned a torque wrench that had the instructions with it has looked at the chart that explains using an extension. All Allan had to do is make one little statement that went against every torque chart out there and BINGO! his entire first run of wrenches are gone in less than a week.

Now he has two choices. 1, produce the video that will prove the torque wrench world wrong. Or 2, call our bluff and admit it was all in fun knowing the topic would explode.

Waiting for the video............

Good point, but perhaps you should wait til the shows over. He may yet eat some of that crow he's saving.

...This is all in fun, and I was only teasing you guys. Don't be so sensitive. I wouldn't really kill any of my crows! That was joking as well, no animal rights guys please. I am about to make a sizable investment, monetarily and in time as well to create an educational video. I am doing this for you guys, not myself. Please cut me a little slack here. If I am wrong, you can bet I will state so in the video and post an open letter to everyone stating so. Soon we will see! Relax and enjoy the ride. Allan

Absolutely. Whatever the outcome, this will be educational. And the tool is a great product that is worth having, regardless of which side of the fence you are on regarding the relevancy of the length of the torque wrench.

all this discussion has the basic principle of torque changed?

In most wrench applications the force relationship may be expressed by the following formula:

F x D = T
FORCE x DISTANCE = TORQUE

Where:

F equals turning force in pounds applied by the Operator.

D equals lever arm or wrench handle in inches or feet.(Whatever the distance)

T equals total force applied to wrench head in pound-feet, kilopoint-meters or Newton-meters

I'll just continue to keep it simple!
My money is with Allan on this one!

When I first saw this thread and the product, I thought of the mechanic on our field and decided to show it to him and see if he had any interest in it, given that he has to remove and install a lot more C/S props than I. It sure looks like a nifty little tool to have. Before I finished looking for his e-mail address, this thread had grown to 10 pages!

I'd see the thread on the main page and it would jog my memory. Still haven't located his address.

However, in scanning through the last 30+ pages of banter, I saw several posts that contained a whole buncha letters-n-nummers and math symbols that brought back really bad memories. In fact, I started to itch when I read a couple of posts that had engineering formulae.

So, to keep this thread from totally deteriorating (after all, Allan has already alienated one potential customer), I have a serious question for him: Does the wrench need to be PRIMED?

Seriously, you engineer-types are in your element. I bow before your intellectual affliction and hope that you will someday find solace in truth.
