Anyone has experience on Mayhew Shake n Break

Like the title says. Just wondering any experience and opinions.

Mayhew Shake n Break

 

[Buckgnarly]

I got it for unit bearing removal, I can use any size socket for any bearing bolt that has a shoulder. Of course I have not had to use it since buying it, but sure it will work great for pushing them out of knuckles.

 

[Mohawk Dave]

1/2" would probably be the one to get, huh?

 

[dudutzu905]

I got both sizes, mostly using the 1/2". I use it for long bolts(subframes, motor mounts, stuff where you definitely don't wanna break a bolt in) that don't seem to initially wanna come out without extra force, that's when I switch to a bigger gun and that's when they snap, learned my lesson... 10-15 seconds with the air hammer while while a helper is putting pressure with a long wrench(depending how big the bolt is). It sure makes you smile when you see that bolt come out with very little push on the wrench when it wouldn't come out 30 seconds ago with a 1/2 impact. A must have in my book - get one!

 

[Arbybe]

I have found that I need to put a couple of washers inside the socket so the
Hammering is directly on the fastener rather than the thing it's stuck in.
If that makes sense.
This makes a big difference along wih Kroll
This process almost always works but you must be patient.
Tool is also known as a "knocker"
We used in aviation

 

[Charles (in GA)]

In aviation that would be a screw knocker. Add a handle to it, and an apex bit holder with a #2 or #3 phillips and that is what you have. Also known as a screw extractor or an old man.

That Mayhew is expensive, the two in the pic are $38 together and are both 3/8 sq dr.

This ^ though , you did not have to call them an olde man .... :{ check www.theyardstore.com they prob have them there . It does work very well in the right hands and on the right rivet gun. Be mindful it is not really meant for thin materials..

What does this thing do?
You put your socket on the end of an air hammer?
Wouldn't that just make the socket fall off the nut?

 

[Cypherian]

Place socket on the end place opposite end in air hammer place socket over bolt depress trigger on air hammer. The in tense and deep vibrations can loosen bolts and in this case you have control so no heads shear or strip etc. Works on bolts or screws as long as the material is thick enough.

I hate to do this, but if this is the case, why is it called the "bolt breaker" and not the "nut breaker?"

 

[Wrenchinfool]

Got 3-4 years ago from Mac I use #2,#3,#4 Phillips and various torx bits with it works like charm.. Better than heat, beat and lube

Cause it goes both ways bolts or nuts and even screws l... LOL I have spent many years honing this rapier wit LOL or Abrasive wit depends on who you ask LOL

I have one, works great, however the wrench would sometimes vibrate off of the hex so I welded a thin bead around the end.

 

[Charles (in GA)]

We use them to remove stubborn phillips screws on panels on airliners. Screws are tight, or corroded, full of paint or whatever. The phillips will cam out and mess up the screw head, but with the screw knocker, it drives that tip in and holds it in while you are turning it by hand. The pounding loosens the screws by compressing the panel slightly, and vibrating it. Have to be careful however as once it is loose, any further knocking on a aircraft panel screw will break off the nutplate on the backside. Once its broke loose, stop and go to the next one.

 

[Jacobson]

I still can't picture how this works. If the bolt if totally stationary, won't the air hammer just bounce back in your hands? And the socket is AROUND the nut, so the nut is not even being touched. There's just a lot of noise surrounding the nut. What would this do??

Like without this tool, if you simulated it by hand, it seems like you're just putting the socket onto the bolt, then removing it, then putting it onto the bolt, then removing it...That would do absolutely nothing to get it loose. Totally confused.

 

[GTA Matt]

Many factory fasteners are shouldered so the socket will be pressing on that part, or like someone mentioned, stack a few washers inside the socket to contact the head of the fastener.

It says right on the for bolts

It's the same thing as an impact driver. You squeeze the trigger and use a wrench to turn the shaft loosening the bolt

Is not going to work for nuts unless you have a 3rd hand. I use mine for rotor hold on screws. But 9/10 I just use a air chisel instead for that

Receipe for nuts:
Use flat or lock washers that the split is twisted together, inside socket so that
The hammering (vibrating) tool is not damaging the threaded end.
Moderate twisting right or left with a short handled wrench will get the nut/cap screw loose eventually.
The principal is the same as using a sharpened punch to hammer a nut,
Capscrew into submission without the damage.
Heating,cutting should be last resort.
Obviously this is time consuming and if damage is not an issue,cut.

Send me all your spare British standard whitworth fasteners.

I still don't get it. What exactly is happening when you put a socket over an air hammer. You're trying to HAMMER the socket onto the bolt? But, it's already seated? All the force is missing the bolt entirely. I can't possibly see how this does anything. Are you twisting the socket at the same time it is jackhammering up and down?

It's about vibration. And yes ,you are twisting the socket at the same time.

 

[Jacobson]

But, how does it vibrate? There is only on/off motion, not sideways.
It sounds like putting the socket on, then pulling it off, but a lot of times.
That would do nothing to remove the bolt, even if you did that for 10,000 years.

 

[BFHtime]

I have used an air hammer with a wide flat hammer was bit if you will, to tap the bolt while turning a wrench. Trigger control is necessary with the air hammer. It usuall works best with 2 people, one for the gun and one for the fastener/part.

This seems to work great for corrosion and tends to be less abusive than hammering the heck out something, and doing damage. In a pinch or when not wanting to run the air line as I use mostly cordless power tools, I will hold the socket of an impact driver, to get a hammering effect on a fastener, it works sometimes.

To the OP thanks for posting I need to get something like this. The techniques posted previously, are the way to go with hammering the bolt not the nut, by adding washers to the socket. Also the lock washers to add some spring to protect the fastener from breaking is another great nuance.

Please post part numbers guys, thank you in advance. It looks like a better way to airhammer. Also will save time.

I just noticed this, while looking at your avatar. Too funny.

That's where the wrench comes in

As other have said earlier, they need to be flanged bolts or you need to put some washers in the socket to contact the head.

Try to think more on a microscopic level. Sort of like an ultrasonic cleaner.
I have no idea what,s going on,scientifically,but if you introduce vibration.. Something is
Going to happen, it's the frequency as well as the intensity .
A well placed hammer blow is intense but infrequent.
If they can de-rust a 1000 year old cannon you should be able to get some oil/solvent mix
Down in the threads of a frikk'in nut.
I hope this helps.
