Broken Tap Removal by Metal Disintegration Machine (MDM)
HTML-код
- Опубликовано: 27 авг 2024
- Tom Grafton of Jerry's Broken Drill & Tap removes a broken tap from a heavy industrial cast iron part. A Metal Disintegration Machine (MDM) or Electric Discharge Machine (EDM) was used to successfully disintegrated the broken tap saving the customer thousands of dollars. The broken tap didn't have a chance!
This is how to remove a broken tap the right way.
He probably doesn't remember me but i brought him a firearm part with a broken tap in a threaded hole. I asked him how much and he said $50 and come back on Monday (it was Fri morning). So I said " What if I gave you a hundred bucks?" And he says "come back in an hour and it will be finished." So anyways He did a fine job fixing my gun part and we BS'd for about half an hour about guns and offroad riding . Really a cool guy.
Now that there's funny, I don't care who you are. You gotta love the guy!
He porbably thought you were a jerk for having a gun
@@daverowe4566 More like thought of you as a jerk on general principles.
@@The_DuMont_Network no the gun thing
@@daverowe4566 not gonna get in a pissing match over gun ownership. My choice your choice.
I find it shocking that there are enough broken taps in the world to keep a private business open. That's amazing.
They probably do other work in between. Most shops do many types of machining.
there wouldnt be if people used the taps right.
it happens all the fucking time in high volume manufacturing.
yeah, well when the guy in charge of buying shit only gets plug taps and bitches when they get chewed up you start getting taps broken off. seeing as the part is usually worth about many times the shipping cost off it goes to the guy with an mdm
very true!!!!!!
What a cool dude! Could watch and listen to him all day. Notice how well spoken he is, no erms or ohms between words. A wise man with a focused mind. Excellent video, was enjoyable and educational at same time.
he talks so slowly tho
@@drkastenbrot and constantly repeating what he already said
Noticed ALL you said myself

@RollinRat Absolutely so so true, of course if they speak you know they understand because they say the same thing,
''I know, I know, I know''‼️®™️
I was a machinist in a factory for ten (10) years circa '67--'76 and somewhat perfected a process of removing broken taps other maintenance techs had broken. I only had small high-speed steel chisels, such as Tom mentioned made of M2 steel. Later I went to work for another company who brought in an EMD machine. Once the factory tech showed me what it would do I almost hugged him. When you work with "bull work" mechanics an EDM machine pays for itself quickly.
Removing broken taps, drills and stripped bolts was my favorite thing to do when I worked in a machine shop. It was a nice break from running production jobs that never seemed to end and you really felt like you had accomplished something and saved the company some money by fixing a part that would have been scrapped.
Ur a glutton for punishment I wish u worked at my shop lol
We have a local retired machinest that bought a Acer Knee mill. And all he does is broken off taps, Studs, and bolts that guys tried to drill out with a hand drill then got the hole off center and made a hell of a mess. The best yet was a head off a 1066 International Tractor that the grandson had a bright idea of using a air impact on a cold engine to try and fix a exhaust leak. He broke off ALL the studs but 1. When I went to look at the job I told him there was nothing short of pulling the head off and taking it to this gentleman. The Grandfather said no problem, And the Grandson just rolled his 20 yr old eyes. And was positive there was no fixing his disaster. So the next day with head in (2 hands) We set it on the mill table and he started his magic. 2 hours later and 5 inserts to fix the out of shape holes. The job was done. I asked him how much?? He said normally he would get $40.00 a hour, would 2 hrs at that rate plus the parts be good?? I handed the man 4 $100.00 bills and said "NO, I think you need to raise your rates on jobs like this" A good machinest an save you hundreds if not thousands in some cases. Sadly the man's getting older and can't do the work he used to. And there's no one younger coming along to do this kind of repairs any more. Its sickening to think these talented men will take this knowledge with them to the grave with out passing it along to the next generation.
I didn't realize there was that much demand to remove broken taps. From the looks of that casting and the work that had been put into it, you saved them a ton of money. Great work Tom Grafton. You keep chewing your gum, to heck with the boo birds.
I bet you it's because of automation. Got a big CNC machine doing tap work which has no 'feel' like a human doing it.
@@gymkhanadog youd be amazed how many people break taps. some real idiots out there
I was thinking the same thing. We usually just weld a stud to the broken tap and try and back it out. Otherwise you have to drill it out in progressive steps.
@@bradhaines3142 ugh everyone in every machine shop breaks taps.
@@bradhaines3142 look out the master machinist Brad has spoken.
That was an absolute pleasure to see in action. Not nearly enough proper machinists left out there who can still use these kind of tools.
Love watching a skilled artisan at work
+pssst3 thanks a lot compliment
+pssst3 also, if theirs any parts that are small enough, surprisingly, shipping is not as expensive as you might think
As a professional and home machinist. The whole process of conventional edm and wire edm was a very hard thing to master for me. It takes skill and knowledge to do this right. I used to take taps out using graphite and trode holders. Never a dull moment
Hi there! I remember sending you a part (model steam locomotive frame) about 8 years ago to have a #5-40 tap removed. Great to see you on youtube.
Was doing spark eroding in the late 70’s early 80’s in our machine shop where dopey turners kept breaking drill centres in their work pieces!
That calm voice and demeanor makes me think that he can do about anything! Great vid.
As a 40-year Journeyman Tool & Die Maker, that was very satisfying to watch.
Good demo. We have a guy near me called 'The Thread Doctor' who travels around garages and workshops doing in-situ work like that, high quality job, with a high-quality price. He has saved a lot of engine castings from being scrapped, so well worth the money.
Thanks, Tom, for a fine demonstration of old-school, pure unadulterated know-how.
WOW what a natural teacher. Everyone who wants to make instructional videos should follow Jerry's example in HOW TO.
I had no idea that many people were breaking brook buys and taps to have such a highly specialized company in operation. Who know someone could make a living doing this. Amazing.
And now you need to make out the invoice. lol
Very dedicated procedure, and that machine, new to me. This is metal surgery at a specialized metal hospital, at the hands of an experienced metal surgeon!!
Hopefully the client didn't acquire an Invoice Disintegration Machine (IDM).
absolute waste of time, this procedure destroys good equipment and clearly resulted in serious damage to the thread
@@jefrhi clearly you have a micropenis
well, the same machine that burns the hole in the tap, also burns a another hole in the customer's purse.
manlystyleunder50, Oh fuck, here we go again, this same old numpty with no brains opens his pie hole again, When I want to hear from an a** hole, I’ll fart.
Pretty sure this guy could care less that you guys don't like him chewing gum. Its his job and hes making this to show people his machine, not to attract huge amounts of supporters.
Couldn't care less.
I didn't know he was chewing gum until I read all the comments.
A lip full of chewing tobacco would be much healthier haha
His shop his rules.
I’ve been a mechanic around 44 years worked on cars trucks heavy equipment and aircraft and have never seen or knew such a machine existed. That’s the slickest thing since sliced bread! Great job!!
EDM is nothing new
Specialized services like this can be a life saver for some people. It's a pleasure watching an old timer share his knowledge with younger guys who have respect for a lifetime of experience. I never even noticed his gum chewing until it was mentioned in the comments. I was too busy watching and learning something new. Great video
No by guess or by gosh, or scratchin' your butt. Just methodical steady progress to success. I love to watch a pro work. Even in my little town of 3,000 people, I swear there is $50,000 of outboard motors sitting idle for broken off bolts. If you ever come to the Gulf Coast, bring your machine. LOL
Thanks for a good, clear video.
+tom jackson Thanks for the compliment
Sharing the knowledge and the information
This guy know his shit!
Impressive, calm, nice to watch... Thank you for sharing Jerry!
Ah, great to see that there are still some old-school machinist folks still out there! It’s the end of a great era....
Brilliant presentation! Have been an old-school millwright for 40 years and am amazed at this process. The feeling of dread is a familiar one, when either a broken tap or easy-out changes the entire scope of an otherwise straight forward job! Thanks for sharing.
Rick (the mech-a-nic)
I might be around Jerry's age. Back in the late 70's my father mentioned that there was this thing called "EDM" that could make a good living for somebody who could apply themselves to it. I was more of a biology/science person and that's what I pursued but I get it. If you imagine not breaking a tap inside final parts, but inside one of a kind tooling and dies for a factory where something went wrong, there's basically no price they wouldn't pay to get that tooling restored and back to work on the line. Figure out what they paid for that one off die to be fabricated in the first place.
My father supplied non-ferrous metals mostly to industry. We had a guy show up at our house after dinner because my dad took home a piece of copper bus bar about 1.5 feet long for this driver to pick up since the warehouse would be closed by then. (My dad was great that way for customer service.) They sent a driver in a 5 ton cartage truck from Sarnia non-stop to Toronto to get that bus bar. That's all that truck came all that way for. The driver was headed straight back to Sarnia with nothing in that 5 ton truck but 1.5 feet of copper bus bar so their factory line could get powered back up.
This is exactly how EDM got started. I worked for a company that built die sinker and wire cut EDM machines 20 years ago. Really neat stuff can be done with those machines.
EDM is a different principle and it is performed in an oil bath.
It is Kerosene not oil, BUT it can also be distilled water ( De ionised )
I would love to look this fit at his age. I like his calm demeanor. Always in control. Good learning vid. Would be amazing to be his apprentice
What satisfying work, and what a great service you provide. I can just imagine how many people over the course of your career have heaved a great sigh of relief when you informed them you saved their bacon.
The amount of money and time you save with your expertise must be phenomenal. Especially if the tap broke very late in the manufacturing process, which is when they are usually used. They could have ended up having to rebuild the entire part to get the precision needed. You also have brilliant presentation skills, you kept the viewer fully informed all the way through. Thank you.
Nice video, good job, I was working on an Owens 30 ft wooden boat in Long Beach, ca harbour assembling an engine in the bilge, cleaning out the headbolt holes from rust, I had a 1/2" x 13 tap almost 1" into a hole, when some a-- hole was speeding through the channel and the wave rocked the boat so severely it through me over the block, and I broke off the tap about 1/8" below flush, 10 hrs of wd40 chisling punching blowing air, I finally got it out clean, plus a Walton 3 flute tap extractor, what a f--%$kin nightmare, anyways glad to see how the pros do it. Thanks

Dad retired as a master machinist years ago and during his career I would often go to the shops and get a little job done here and there. He was a master in every sense and could do the most extraordinary things with metal. I remember him describing this process but never saw it performed until now. Of course, Dad's response would be "don't break the tap." Well, that's good advice but stuff happens. I only broke one tap in my whole life and was able to twist it out with a pair of needle nose. Whew! Lucky.
Scoop oh man, U're really, really lucky ... I've got a 'new' motorcycle last year ... only 30 years old ... had to remove 3 broken bolts for just the first month ... lucky me they were not high hardness. Unlucky me one of them is actually not a bolt, but welded holder with threaded end. But anyways, can't use such machine. This is kind of specific, I see the workhead can't angle, so you have to level the part somehow. It is utterly strange the yellows are not selling such machines in hundreds already. But of course re-modeled for 'home use'.
@@drgrunn174 Wow, I would love to see what you're up to. It's possible Dad taught me some trick that would help you out but without a clear shot at what the problem is . . . well good luck is about I have to offer. One thing though, wonder if someone with some real know how could develop a hand held device that would work. I'd say that guy would make a few bucks.
I was aware of the EDM technology but have never thought about using and EDM machine for broken tap removal.
This is great
I sure enjoy watching a true craftsman work. Would love to spend time talking with him. Well Done, Sir.
You know when an old pro is teaching. Good job.
Cool machine. Did not have one around when I needed it. Had a 300SL in the shop with a broken tap in the cylinder head. Instead of pulling the head I got my Dremel with a few ball grinding stones and ground thru center of tap in about 30 min. Removed the flutes and found a broken stud below that. Did some more grinding to hollow out the stud and collapse it. Saved a $7000 head in 1.5 hr.
Sounds like something I would attempt to do. how did you center it and how did u get to that depth to get the broken stud. how was it held so steady that u did not hit the threads?
John Conrad Thanks for the question. The amount of stud in the head was shallow. On a 2 1/4" long stud only 3/8" of it is in the head. This seems to be common with European DIN studs. So the Dremel ball grinding stones had plenty of shank. As for holding it steady I had the intake and exhaust manifolds off so I could crawl into the engine bay and brace myself. Then just grind a little bit at a time. I submitted this as a Tech Tip to Engine Builder mag couple years ago and they published it. I had no choice but to do this. Didn't have access to Tom and his cool machine.
Im an EDM master 23 years now - I do it all, hole pop,wire EDM, sinker EDM ! cool video man !
Thank you very much for sharing your knowledge, Mr. Grafton. It was a privilege to watch you work.
He has probably forgotten more then most of us ever learned ^^
In England this process is called Spark Erosion.
Fascinating! I'm a 66 year old gearhead who does a bunch of my own work and I love these kinds of videos. Super cool, Jerry!
These elderly master craftsmen could put newer engineers to shame...Loved every bit of this Video.
This is a craft I didn't even know existed. Cool
The hard rods are no longer the rockwell you state after grinding. When you grind it and you see that metal change colour, that's the metal losing it's hardness and slowly becoming annealed.
The tip need not be that hard to fuck the hell outta that dead tap shred. the back needs to be hard so the hammer could strike it well.
I have always wondered how professionals did this. Thank you for showing that.
Great job Jerry, seen this done in the early 70's, always interesting to see this special work completed. Thanks
Wow, I was so in to the tap removal, never noticed the gum. Soap opera people do ,I guess .
Mike Sokolow Or little nerds that couldn’t turn a screwdriver but know 69 positions on butt-fuckin
Who could _possibly_ give this a thumbs down? Why?
Some people's kids, Jesus H Cri...!
All I wanted to do was go to sleep because I'm exhausted but I couldn't stop watching. I wish everybody making a video was as cool as this cat. I get the feeling there's nothing he couldn't do. And if there was something he'd tell you and be right about it.
Wow Tom I could listen and watch you talk about extracting broken taps all day long. Great job! Ugh what a head ache broken taps are... I remember when I was learning Machine Trades I became very familiar with the RAM EDM as I had to burn out a lot of my own broken taps! Those "tap remover" tools very rarely worked!
I use carbide used endmill , about 70% smaller diameter then the happy itself, to fill out the tap.
Of course works only on HSS taps.
Thas called removing broken taps like a boss
Machinists are the coolest people with amazing knowledge and skill.
That was practically a life-changing experience watching such a professional approach to handling the problem. ... a great example to follow, and I think I will!
Excellent video, kept me riveted (LoL) the whole way thru.
Oh and I'm 71 and I can't chew gum it sticks to my dentures, keep chewing !! 😆
Im 28 lost my front teeth at 16. I can't chew either sticks to my partial dent
All that effort I’ve done using busted old tap extractor kits 😥😥😥 and here you are relaxing on the damn deal 😂😂😂
Exhilarating to see someone on RUclips that isn’t a total hack. This man knows his trade and does it well. Good job Tom!
Man that’s cool. I bet that tool is exspencive as hell
Wouldn't it make sense to include the service of finishing the taping for a small fee?
1) the customer doesn't have a tap anymore 2) if you break your own tap again finishing the job, you have the means to get it out without too much extra cost, the part is already on the EDM table.
+nraynaud1 You'd need full specs for the tapped hole - thread depth, thread tolerance class, bottoming or taper tap.... much better to let the customer finish the job than risk screwing up a big, expensive part! Plus, there's likely other holes that still need tapping.
Very interesting. Tom is well spoken and a pleasure to listen to.
At Kearney & Trecker we had a tap burning Machine very similar to this one, but I never was shown how it was done till now.
Thank You for the excellent demonstration.
This shit makes me happy. Old school techniques shared.
worst technique ever, incredibly time consuming, ruins good equipment and causes significant damage to the thread
so this is where iron-man ended up
Had a smaller version of this machine at the machine shop I worked at. It had a chart with common standard thread diameters against electrode diameters and machine heat settings. We could burn out between #10 to 5/8" diameter and simple calculations allowed for metric conversion. For some reason I was fascinated with it and took time to clean the machine up and organize the electrodes. It wasn't long after that it became my duty to repair broken taps for all of the machine shop and mechanical assembly. Most taps were broken by manual drills going into large steel tubing followed by bottom end taps into aluminum, again manually.
In my 2.5 years at that company I had burned taps out of many different mild steels, cast/6061/7075 aluminum, and phenolic which is a plastic composite for high temp applications. I used old center punches ground the way Jerry used his M2 magnetic chisel. For larger than 5/8" broken taps, which was rare, I'd burn a 1/4-1/2" hole and slide a bolt in, tack welding it in place and turning the tap out as anything we had of that diameter was a through hole and cold be accessed easily from the other side, with few exceptions. Aluminum threads that were cleaned out usually were drilled out after the tap was removed and were rethreaded with a special insert depending on application. Aluminum is very gummy when machined and takes special care to ensure it doesn't weld to the tap. Something that when using a cordless drill will happen instantly if the drill is wobbled and the clutch isn't set right.
Another place where people screw up is trying to "eyeball" a drill size to the inner diameter of a tap. The smaller the tap the more precise one has to be and the blueprints will specify the basic minor and major diameters necessary for the drill. Engineers [should] take care when they specify those sizes since different applications require different contact areas between the screw thread and base thread.
The first time I ever heard of a metal disintegration machine was when someone was doing a performance build on a 7.3 Powerstroke engine. Someone installed tool steel head studs to handle the pressure, but one of the studs broke. All the usual methods of removal were tried, and it was determined that metal disintegration was the only solution.
I didn't read through every comment on here, but I didn't see anyone bring this up. He mentioned that he has these chisels that have been tempered to a certain hardness. He then proceeds to sharpen them on a high speed grinder to red hot. Doesn't that remove all the hardness or tempering and normalizing that the manufacturer put into them? I'm no expert, and don't profess to be. Maybe someone that knows can enlighten me.
in theory it could, it depends all on how long the heat has time to travel trogh the workpiece. If you grind only for a short time it has very limited effect on the hardness.
Also keep in mind that the part which is glowing is also grinded off.
Keep the grinding time short. If you need to grind more , always have a water pot nearby so you can cool the part every ~3-8 seconds or so ( you can feel the heat with you fingers, if its hoo hot to hold, you are too late, cool it before you reach that point.
the tip has lost its hardness at that point, yes
I think he only got it to dull red, not cherry red.
once I heard the chewing I could not stop hearing it haha great video.
Its been an honour to watch you at work
I had no clue that this was a legitimate service. That hunk of machining that you removed the broken tap from was gorgeous.
Excellent work sir, that's a cool ass machine.
Lol at you entirely ruining the temper on your “hardened” m2 chisel on that grinder. You can actually see the tip glowing red. Lol
I guess you think he never did this before. I would venture to suggest that the chisel isn't meant to be sharp, just tough.
I guess you don’t understand the basic heat treating/metallurgy. Chisels are meant to be in the 40-50hrc range. M2 steel is usually hardened to around 61hrc and above. So this would be kind of a special purpose chisel. Heating it up to the orange temps(1500f or probably higher from what I could tell) isn’t only going to drop it beneath that hardness, but it’s going to completely ruin the heat treat. If he intended it to just be any old chisel that would be super soft, why the hell would he use m2? The fact that he took the trouble to mention it was m2, leads me to believe that isn’t the case. Lastly, doing something wrong for a long time doesn’t make it right.
He never specified how exactly it was hardened though did he. My supervisor showed me nitrided ejector pins that looked almost identical to those he used. Hardest metal ive come across and would be perfect for this job
@@jamesmgordon83 He told you it's M2 High speed steel. You can get it red hot without affecting hardness.
@laurie Agnew He went to the trouble of saying “m2 steel.” That is a tool steel and it’s meant to be heat treated before use. Otherwise any old mild steel would work. Seriously, I don’t know how this is hard to understand. In regards to the “nitrided” ejector pins, that is a process that only hardens the surface. Once you sharpen it a time or two, it’s gone.
Insane, I had no idea!
The process has been around a lot longer the most people realize.
Tom Grafton Brilliant, how much did that rig cost?
tickyul 25,000.00
Tom Grafton YIKES, that's a LOT of repair jobs! Well, then again, seeing the complicated jobs you do......maybe not THAT many!!!!!!
You would learn more with Tom in a week than a year in school. I appreciate the video.
Thank you Mr. Grafton for showing this. Scares the heck out of me when I tap a pistol so I use a new tap and use carbon steel so I can use an carbide endmill to remove it if necessary. When I'm making things at work, I'll tell the engineer how many operations are left where I can turn my work piece into scrap. :)
Hey Jerry ... does grinding the M2 Chisels not draw their hardness ??
Great vid by the way 😎👍☘️
M2 is HSS steel and probably they are tempered to "red hot hardness" - but even if they get a little softer, they seem to work well for him🤷🏼♂️
@@kknives_switzerland yeah... Its jist that I've ground a lot of hss over the years & tbh I've found that "bluing" it during the grind doesn't help with tool life, on the capstan lathe I ran, despite the "red hardness" attributed to hss... but as you say, it seems to work for him ! 😉
Thanks for chipping in !
😎👍☘🍺
@@peterfitzpatrick7032 I totally agree on the blueing part; I run all my grinding equipment water cooled for that reason - in knife making, not the slightest discoloration is allowed to occur.
@@kknives_switzerland I'm assuming its flood coolant... No dipping a hot piece in cold coolant.. 🙄😏
I dry-grind to reduce the risk of micro-fractures... just takes a little longer... 🤓
But I'm mostly only grinding hss blanks so not as critical as your grinding sounds... 🤔
😎👍☘️🍺
@@peterfitzpatrick7032 Yes, flood coolant! Got some videos up on it if you want to take a look. Thick blanks are an entirely different game than a 0.015 inch thick cross section like it is common in knives - let alone the edge itself! Always cool to peek into other crafts!
People must be breaking alot of taps for you to be able to make a career out of this lol. Best wishes.
Like " this old codger " , I am 65 and still working as a millwright and chewing gum constantly. It helps the brain stay sharp . Nice work Tom , beats the hell outa working hours with small chisels .
Not sure how I ended up watching this, but this old dude is cool. Reminds me of being a teenager I used to sit around and listened to the old country cowboys, I mean real cowboys not Urban and I'd be amazed at some of the stuff they have done and how many hours they worked a day
Excellent. Wouldn't it be funny if the tap you used broke off again in the hole. :-)
***** It's happened!!!
***** I was joking. (That's what the sideways smiley is for) :-) But Tom (above) says that it has happened.
***** Chasing threads just means gently running the tap through to check the integrity of the threads. Tapping is where you actually cut the treads and he did say he was chasing them. I've never seen someone break a tap chasing threads ever.
***** I'm sure the company that broke the tap weren't using any cheapo taps; judging by the piece they sent in.
were not in church or in a formal setting, chew on brother.
You are awesome!!
Keeping alive techniques and professions that are slowly disappearing!!
If my tap ever breaks, I can only hope my doctor is as skillful as this man.
Jeez spit the gum out
Yeah, I'm gonna throw a guess that he doesn't give a shit Blayne
ASMR for the people who love hearing people chew gum... Me on the other hand. I can't stand it
Fucking mounth clappng pig, can't listen to this abomination
Not gum, it's the putty. Chewing keps it moist and reusable.
Did you learn something new or saw something new... wow I would of loved to have you tube when I was a kid
I recently found that you can drill through the center of a tap using a carbide endmill. Had a customer with a dually wheel extension for a John Deere tractor. Two broken bolts and a broken 3/4 tap. 2 inches of engagement and nothing above the surface of the flange to grab. Drilled straight through the hss tap. Bright red chips even with flooding it with cutting oil
I would have thought drilling it out with a carbide drill would have caused less damage than he did to the threads
The days of old school machinist like this man are over unfortunately.
That chewing gum sounds are driving me nuts...
if you are going to make a youtube video, take the time to spit out the gum. Rude.
the man looks like he could probably break you in half with a look. He's been at this for years, and his experience speaks for itself. If he wants to chew gum, let him chew gum, man. He's earned it.
quit your fucking bitching and enjoy the video
Why is it rude to chew gum while talking?
hey now, picky as he is, no one deserves that. he just didn't like the dude chewing gum. Is that really worth saying things like that? I'd rather remain quiet and be thought an asshole than open my mouth and remove all doubt.
Be kind, people.
Lol. "he's earned it". Either it's loud, obnoxious and disrespectful or it's not. I've worked very hard in my life too - so what's this supposed to be, a comparison game to see who deserves to be obnoxious or not, or who could beat up the other person or not?
This machine reminded me of a small bench model I used to use way back in 1965 for removing broken taps working for Lesney Products the Matchbox toy company, it was called an AGEMASPARK, brilliant idea.
Bravo to YOU!... This kind of expertise is not seen by every human!.. The precision and the thnking that goes into the process of repairing, what ever goes wrong, is what lands on hands that are capable!.. Bravo for making this so easy understood. Thank you for sharing your experience!..
dude... the gum ... really....
probably paranoid about his breath after smoking a huge joint
All I hear is his mouth smacking gum! I can't watch it anymore or I will vomit!
What we called 'Spark Erosion' process back in the early 60's. The 'Jaguars' fitted to the bonnets (hoods) of Jaguar cars were made using that process. Great video. Thanks!
A pleasure to watch a craftsman. Well demonstrated and explained.
Great video. But man dont chew gum while recording your audio like this .......
+Isaac Dahlvang hard habit to break, but i did, thanks to your comment!
+Tom Grafton great job on that! stronger than I am haha. I can't get off cigarettes. thank you for your response!
the open moth chewing and talking with gum in his mouth is very distracting. sorry.
nah
that guy is cool as fuck he can do what he wants
I think the subject matter is great. Just wish it didn't have the extra bit.
You better be fuckin sorry.
Sean K yeah, i hate when those moths buzz around chewing and eating your cloths and shit....and those moths with gum are worse. I got a bug zapper just for those moths. Those moths get really upset when you confuse them with butterflies 🐛
Way cool machine you got there, Jerry! Reminds me of air-arcing welds at B & W in Canton, OH back in the early 70's! Awesome video, 5 Stars! Thanks for posting. You're an artist...
There are a few times during my career that I wish I'd had one of those machines. Nice work.
That gum chewing though.
God, man, take the gum out of your mouth when you talk to people.
haha, i hear ya man my mom tells me the same thing all the time she's so lame
respect your fucking elders
therealnightwriter Alright man. I´m sorry for being rude. I love your work.
+Richard Spikman I'm on the shiter watching this video and reading these comments which I read a lot of comments and by far that was the best hands down I've ever read I came to tears, good work buddy!!
Moron.
Years ago, I had heard about this "Tap Disintegrator" technique - this is the first I've actually seen it. Very nice. I would never touch a job like this with a TiG rig or a grinder - too unpredictable. Also, ain't nobody using harbor Freight taps on that casting. The taps used on pieces that expensive are hard, and tough. not the kind of tap you can Dremel through without risking damage to the part itself. Great video.
Great video I worked as a welder fabricator for 38 years retired now ,And broke many a tap building ski lifts I sure do miss working in the shop welding and Fabricating anyways keep the videos coming... be well
