Amazing new stud extractor

[KiWinUS]

46 studs out on 40 minutes. Only broke 2 & maybe could have avoided. 2 months ago they all felt like they would break. Soaked with Howes penetrant. Purchased this cheap $16 stud extractor off eBay $16 that you can use an impact on. Used my powerful Mac impact. I had to bore center of extractor all way through with 1/2 endmill as it’s hard. What amazing results.

I have one like that and decided I didn't like it. I didn't like the way it is hard to detect when a stud is going to break. The part you turn keeps moving and it is hard to tell if it is the stud or the tool moving.
I didn't use an impact with mine, though. Maybe that makes a difference.

Hey Tony - what do you mean you had to bore the center all the way through? What is that all about?

[KiWinUS]

It has a 3/8 drive square as well as the 15/16 external hex. I wanted it to grip at the base of stud as close to the deck as possible so I bored the center out with an end mill ( it’s hard). Now it drops all way down on stud. As well as impact I used a 1 7/16!wrench briefly on outer housing. Probably not needed with impact as once it starts to grip it keeps tightening its grip. It never slipped.

Mart I believe the impact is a key part of why it worked so well. Particularly a powerful impact. I didn’t care if they broke as I will drill broken studs with 1/8th drill & then blow out with gas torch. Just too easy & barely heats the block or it’s threads.

[Mart]

I think mine was the 1/2" drive version - it fits over without needing modification.

[Mart]

Kiwi, any chance you could video that process? I tried it and made a real mess. But I have no oxy cutting experience.
If you do film it on your phone hold it sideways. It makes a big difference to viewing.

Mart.

Mart it may be a couple of weeks but sure I will try.

What does the inside look like? Jaws like a drill chuck? Does it mark the threads, are the threads reuseable afterward?

[JSeery]

I've used one similar and liked it.

Jaws similar to a drill chuck. On flathead studs the jaws do not get into the threads.

Dale I have just ordered a second stud extractor. When it arrives I will take pics before I modify and show both together.

Much appreciate it!

Tony:

I'm glad to hear you had success with this unit. My buddy, who is a Snap On dealer, gave me one as well and he sells it on his truck. I did not have as good of luck as you did.

At times, it would over clamp and I would have to take a breaker bar to break it free. The studs I was using it on gave me the fight of my life, so that could have something to do it as well.

I still have it and will try it again on another project.

Hi KiWinUS; Years ago when I was visiting Walt Dupont he showed me his extractor, I got one right away. It's been so long now I can't remember where I got it. It looks like a deep socket and is bored all the way through and will handle any length stud and is turned with wrench. They come in different diameters and is the best I've found. Soak studs in a fifty fifty mix of automatic trans fluid and Marvel Mystery oil. Don't use a plastic bottle. If you break a stud weld a washer to it with a smaller ID than the OD of the stud then weld a nut to the washer. Important you let it cool first and then just wrench it out. if the nut breaks loose just reweld it and it will work. Good luck, Craig.

You can find them on ebay under roller stud extractors.

Thanks Craig. I have a full set of that style extractor unfortunately you cannot use an impact on them. I believe the impact is the key to this new extractor working so well. After close to 50 years of messing with these classic old engines along with many others, I have tried most every penetrating fluid concoction and every imaginable way of removing broken studs. For me I have narrowed it down to Howes penetrant & a drill & gas torch for broken studs. Quick & easy with zero issues. Thanks for your input.

Thanks KiWinUS; Ron told me a little about you some years ago, all good. Anyway thanks for sharing your experience and I'll have to try the Howes. So do you drill the stud heat it,let it cool and and then use an easy out?
Thanks again, Craig.

[Mart]

Easy out? Easy, out? Wash yer mouth out! The last thing you want in a broked stud is an easy out.

Hi Mart; I was laughing out loud when I read this, thanks, Craig.

LOL I’m with you Mart.
Use gas cutting torch have it set just like you going to cut 1/4inch thick steel.
Drill 1/8th hole all way through broken stud in block. Now take gas torch heat broken stud until it’s very red then pull lever & blow molten metal through into water jacket. Careful blow all of remaining stud out. You will see it does not even heat threads in block up. Clean hole with “real” thread chaser.
I have seen way more heat put into block& threads by people trying to free studs.
Good luck.
Cheers
Tony

They're also sold by Jegs, Amazon, and other retailers.

The one being discussed here, is a chuck type. It's like a self tightening chuck that only works in the undoing direction.

The roller type is a different type. I have a roller one here that is for 5/16 studs. It was used at the factory for putting studs in the A series mini engines.

Totally correct Mart. I have never seen the roller style you can use an impact on. They self destruct with an impact. This chuck style can be used with an impact.
Oooh Mart why did you have to remind me of your wonderful British motor cars. Like most every thing on the minis to change a lower radiator hose is pure fun. I worked on all those Austin’s & Morris creations in the early 70’s from minis to big dump trucks. An the same garage I also maintained a fleet of 41-47 Ford US pickups. Quite diverse.

Kiwi I have a Mac impact and they are amazing aren't they? Crush sleeve on a one ton rearend no problem, rusted off cotter pin on perch pins no problem just brings it right off!

Bringing this back up, as I purchased one of these back in 2021 when this came up the first time. I finally had a chance to use it yesterday, as I needed to pull the short studs on a 59A in order to put tall Edelbrock heads on. I was able to pull the lower studs, plus 3 for an offset generator mount in about 30 minutes, and no broken studs. I was very impressed. Thanks for the recommendation.

Neal,

I agree. This tool and the heat induction tools (like the Bolt Buster) are game changers for us in the old car hobby.

[The Liberator]

Looks like a good tool, almost looks like the extractor that has the sprag bearing design.

[jimTN]

There are some stern warnings about using the heat induction tool near a pacemaker and other bits of metal in the body. I would think that stainless implants would be safe.

[OldGold360]

I removed the studs from my ‘36 LB today and the first 41 came out no problem, but that last one decided to break. Why does it seem like it’s always the last one that gives us problems… or is it just me?

[Zeke3]

Nah, I removed the studs from my 37 21 stud engine, the first 40 came out okay, but #41 got me. I was able to finally get the remainder out recently. I should have followed my son’s advice, “let the machine shop remove it.”

If I had to do it over again, I would go right to welding a large flat washer and a nut on the broken stud.

[tubman]

Another reason I'm an "8BA guy".

[rotorwrench]

It looks like a collet type. My old Snap On set is a bit longer to give a good taper length to the collets. I've pulled and installed many a stud successfully with that set. The old Snappy stuff came in metal boxes. I don't know if they still make them or not.
