I vote tard. I could loosen 10,000 lug nuts with a 24" breaker bar in the time it took him to make that doohickey thingamajig that will fit no other place but wheel lugs.

I would vote for the breaker bar ... the do hickey is retarded ...

I think it's kind of a cool hobby thing to build. Lord knows there's plenty of manual impact wrenches out there, probably with 100 year old patents mostly, but home built stuff is OK in my book.

What he really needs to build is something that loosens all the lug nuts at the same time.

Now THAT would be cool!

I suspect the basic patent for an impact wrench would include this device, nothing technically new that I see anyway.

yeah i could so the same job with a breaker bar and not have to worry about a spring coming off and poking my eye out.. or i could just get my impact gun..

Impact gattling gun?

I'd like to see him use that on the lugs on my Dodge Ram. Those things were tightened down so d*mn tight that I ended up having to buy a new impact gun just to get them off. :)

Loosen a lug nut a 1/4 turn at a time? This guys a crack; I don't think you could make the divice any larger if you tried....

Weak. That tool wont work the minute you encounter something torqued higher than the strength of the spring set. All it will do then is fully stretch the springs....

maybe , if he built something that could take off all lug nuts at the same time.

I vote genius. I think the guy did a great job. I love this kind of ingenuity. Basically its just a spring loaded hammer (slug wrench), but effective none the less. I wonder if he just copied an old patent???

This looks like something you would see in a Harriet Carter catalog.

What he did is copy the function of a Swench manual impact tool. The swench works differently as far as the mechanics go, but the function is the same, pull it a ways against the spring till a pawl trips and the spring slams it.

I have three Swench tools, 1/2, 3/4 and 1 inch drives. They are made by Curtis-Wright and are used by the military and in oil fields. They hit hard and will get loose nuts that a regular impact won't touch.

I wonder if he just copied an old patent???+1 good idea. If he gets a patent on it he will be laughing at us. There are plenty of guys that have made big bucks from far less. It is a simple spring powered slug hammer and I bet it could be mass produced in compact and inexpensive form. The auto makers could throw that in next to the crudy jacks rather than the long breaker bar contraptions.

I love to see guys make things like this in their home shops and garages. The ingenuity of individual Americans is one of the things that made this a great country. Still, I would go woth a breaker bar myself, but hats off to American inventors.

The Swench is one of those tools that I would never need - but love to own just because it's a neat piece of machinery.

That looks pretty good to me. I mean, in the 2nd clip, he's using a smallish crescent wrench!

looks like a good idea, howeer it a solution to a problem that does not exsist.

for the application, the breaker bar is better, cheaper, safer, easier to use, takes less space, and will be more reliable.

for a special application it is genius (other than the fact that they aleady exsist from someone else)


he should sell the idea to HF so they will make them and sell them for $19.99 on sale ans a bunch of fools will buy them

Since the Swench ones are good for 600lb/ft-upwards i wouldn't really want one of those to fail catastrophically in my face at full tilt..

dont worry, the HF version will only be good for 60 lb/ft on its best day so it will be far less dangerious

This is an example of why you do research before making something you may believe new. You waste time reinventing the wheel.

Now making it to learn how to make that is different, but does not seem to be the case here.

Actually, after watching the video again, I can see this being a useful thing in my wife's car. Even when compared to using a breaker bar, I think this would require less effort from her to get her lugnuts off in the event that she has a flat and I'm nowhere around to help her.
