- Hi.
This video shows - the whole production process of the dowel pins puller.
- milling - drilling - turning.
When repairing a cylinder head with this tool the pins can be removed and reused several times.

I had excellent results over the decades by threading a tap into the dowel and grabbing it with a slide hammer and giving it the tappidy tap tap.
If it isn't hollow, drilling it and creating threads in it works, too.
A pliers often works, too. Just don't be aggressive if you don't want to damage it. And if you do damage it a bit, that hasn't been much of a problem.
how do you mean? I have dowel pins that have sheared off in the engine block, to where I can't get any grip on them at all. They are hollow however, so I am wondering if your method would work on them. I just dont understand what you mean by threading a tap and grabbing with a slide hammer. I'll try research it using the approach you've suggested.
@@antiochiaadtaurum3786 hopefully I can clarify.
Before I begin, keep in mind that one option is to drill them out. You will need to get new dowels, but they are shot anyway from the sounds of it.
Of course, there are solid dowel pins and there are the ones that I referred to as hollow, like a really short piece of copper water pipe. I like to use a thread tap and create threads in the hollow dowel. The threads created should not be very deep--definitely not as deep as you would normally want to create when making threads. Sometimes the tap will bottom out and pull the dowel right out that way. Sometimes you can hit the tap from the opposite side once it is threaded in. I recommend a brass or aluminum hammer to reduce the risk of breaking the tap. Sometimes you can install a nut/washer on the tap with an even larger dowel that fits over the one you are removing to be used as a puller to remove the dowel. If a larger dowel isn't available, even a short piece of 3/4" copper pipe can work well.
If none of that works, heat the aluminum housing with a mapp gas torch hard and grab the dowel with a vice grips and it would not surprise me if it literally falls right out.
I should also add that the slide hammer is used with an adapter to attach it to a vice grips. I thread the tap in, grab it with a vice grips / slide hammer combo and pull it right out. It USUALLY works, but some are much more stubborn and this won't work.
There is always a great since of pride when you can make your own tools and they do what you intended the tool to do. Nice work and I really enjoy watching your videos and the repairs that you make! :)
I've been an engine builder and machinist since 1991 and pulled literally thousands of dowels.. all I've ever used is a screw extractor and a tap handle to pull them out .. 9 out of 10 come out damage free .. this guys making something simple more difficult than it really needs to be.
Understand.
In old engines it goes with ease.
In the new Ktm engines it goes badly out.
@@PaulXchannel I get them out no problem . I also stock all the dowels for everything I work on .. if you spend more than 2 minutes removing a dowel you just lost money if you're working on these things for a living .
Ok
Pete I agree with you. Can also use a drill blank or shank of a drill bit the right size, put it in the centre of the dowel, clamp the dowel on the outside and pull it out. Done in seconds instead of making complicated tools on the lathe and milling machine.
@@mickl8212 I’m with u , 30 years, u use punch inside, vice grips lightly twist, damage free
There is nothing like having the right tool for the job.👍
Can't believe how few subscribers this guy has its criminal.
You really make a consistent set of use cases for why I "need" a lathe...
So you need to spend $15,000 on a lathe and mill to make a 40 cent pin.
?
When you make 37 500 pins - the money for the lathe a mill is back.
@@bsiegloff You'll notice I said "consistent"... I'm talking about across all his videos, not just this one, lol.
@@PaulXchannel 😆
@@PaulXchannel True.
May have rush out and buy some machinery so I can remove the pin I dont have.
Tried using the pilot bushing method of filling a hollow dowel pin with grease and striking it with a drift pin to hydraulicly blow it out of the case.
No workie..
Wound up ripping & tearing like an amateur for an hour and a half, then waiting a week for a $1.50 dowel.
Brilliant work.
Brilliant!! And now it's off to my lathe, Thanks
Next time I have a stuck dowel I will remember this process; it's as easy a 1,2,3,4,5,6,7,8,...99,100.101,...476,477.... and done!
Trabalho de um digno profissional. Parabéns 👏👏👏👏
Со всем уважением. Но слишком сложно. Имея токарный станок, можно выточить новые направляющие, не потребуется фрезерных работ. В данном случае можно взять цанговый патрон для фрез и так же извлечь направляющие. Я обычно нарезаю резьбу подходящим метчиком и обратным молотком извлекаю направляющие. Видео кинематографичное. Молодец. 👍
В точку. Как и сделал бы человек с действительно разумным подходом.
Sir, you are good at developing ideas between synchronizing tools and materials. To make work easier.🙏🏻
Super satisfactory to watch, as your other videos. Thanks!
Usually i just use a plier and put a snug fit stud in the dowel pin to make sure it dont crushed. Btw, nice video and invention.
Paul, la verdad me sorprendes, tienes mucho ingenio y facilidad para improvisar, tenemos mucho que aprender, gracias por compartir 💯
Excelent job!! Well done👍👍👍👍👍
Excelente idea , y un trabajo muy bien realizado , MAESTRO muchas gracias por compartir tus conocimientos , un saludo ! ! ! ! .
The best! As usual ....
my fav youtuber
That’s awesome 👏 presentation
Nice work my friend.Big like from Arad-Romania!
Нарезаешь резьбу внутри, закручиваешь болт в резьбу, выбиваешь направляющую длинной выколоткой. Минимум проблем и времени...
Felicidades por el trabajo.
I love the filming
From Indonesia, Good idea. Thank's
GENTIEMAN.... FANTASTIC... GENIUS....
Все гениальное ,просто.
Tu es le meilleur..... 👍👍
I just stick a matching piece of round stock into the dowel pin and then grab it with the three-jaw chuck of the lathe. A little wiggle back and forth, and out it is.
Loving your vids mate. Why would anyone thumbs down to this?
Very cool 😎
Nice!
Very clever
Nice work,i will need to machine some of these up. I rebuild Sachs Wankel motors and always the dowel pins are stuck in the rotor housing or the side plates.
I might have to make one of those good job Paul. I'm tired of wrestling with dowel pins.
For those who do not have a metal lathe use a drill to make the hole. Or if you don't want to drill and do all that stuff at the very least put a drill bit in the inside diameter of the dowel pin. One that fits nice and snug. Then duck tape the outside diameter of the dowel pin and then grip it with pliers it leaves a lot less damage to barely no damage.
Очень качественный материал.технически развитый специалист
Es realmente obligatorio usar esas guías? Hace poco arme un motor de moto sin esos porqué no pude sacarlos
Good idea.
Very nice
Its easier to pull out the pin with pliers, then buy a new pin for a few cents.
Motion pro has a dowl pin puller set. They work very well.
You can also take a wooden dowel and or a broom handle, (wood). Grind it down to a perfect fit, ID, tap it inside of whatever hollow pipe or tube you are trying to remove.
This way the pipe, tube will NOT crush, collapse so you can use channel locks.
Or a strap wrench to twist.
Works every time.
Also you can wrap some duct tape around the outside if you are trying to reuse whatever you are trying to remove.
Better to buy new though.
The milling machines i done my apprenticeship on has so much backlash you never dared to climb-mill 😁
I now have a use for my old collets
Nice.

Hello pro nice video
An ER collet chuck works perfect. Mine has an M10 for a drawbar. With a slide hammer the dowel pins move easily.
👍
A dowel pin is a standardized part which can be replaced frequently. To pull(turn) it out I use a broken stud puller. 1min against 1 hour time. Shown method with partly preheating can lead to distortion, too.
Tanto trabalho, retiro com o alicate bem de boa 👍
A good pair of diagonal cutters ( dykes) and a flat blade screwdriver usually will work .
Ottimo!
Simple way is use a thread tap inside the dowel and then use punch to hit it out
Another easy way put something round inside of dowel then use vide grips to remove
Also if damaged outside of dowel with pliers ect just file off burrs and refit into block/barrel upside down no worries
Genioooooooo
Super my teacher
Did a lot of screwing around , just use a tap thay work really good for Halo locator pins
split a nut and use the same method as this, no lathe required, or get a tight fitting bolt to go inside the dowel pack the dowel with grease and tap the bolt down the center of the dowel
Yeah i am going to buy a lathe machine so that i can remove my dowel pin too🤣🤣🤣
Good
Meu deus, um jeito muito mais fácil é colocando uma chave dentro do guia, e com um alicate de pressão apertar e girar o pino. Complicou demais aí!
of course i have this machines to make a dowel pin remover
A regular socket and a hose clamp or lock collar will do the same thing if you don't have all of the nice machine shop tools
usually we use the tail end of a drill bit w/ just the right clearance of the dowel and a vice grip to finish the job...
nice work as always! you could use cheap er collets to grip pins but making your own tools
is more fun!
I always use a collet of an appropriate size.
La gran temperatura q levanta eso
Parabéns pelo trabalho, acompanho do Brasil...
👍👍
For the people that hasn't got a lathe, you can just screw the correct size tap and hammer it from the other side
I'd wrap a thick cloth around the dowel pin and give it just the right squeeze with a pair of pliers or a vice grip slowly nudging it out🤔
The butt end of the proper sized drill bit would be way easier, and most likely what the normal guy has on hand......
hey paul do you know the exact bame of this pins i need it for project but doesnt find pins like this
dont mean the puller i mean the actual pins in the motor
YES YOUR A CLEVER LIL BLIGHTER 👏
IF A LOT IF FOLKS HAD THE $$$ FIR A COMPLETE TOOL SHOP
BUT THEN AGAIN
THE ABILITY TO OPERATE ALL THE MACHINES WHICH IS NOTHING LESS THAN A GIFT 👍🤙😉
TOP
It works, however, if you drill a 2 - 2.5mm hole across the dowell and insert a steel pin, then heat the part and using the big pliers twist the dowell by the pin.
👍
New dowel pins 1€?
Still a nice video to watch though 👌
How many people watching this have a lathe or a drawer full of aluminum round stock? Personally I've always just pulled them with pliers.
Never tried it but not sure you couldn't jack them out with grease or bread with a drift pin and hammer like a pilot bushing for a transmission.
Have you made the tool for getting the water pipe out of KTM frame yet?.....a few years back a friend rung and said he was trying with mole grips....I said STOP now...went off to see my local 80 year old magician and he made me the perfect tool....
Yes
Indexed drill bit and pliers!
Just pour boiling water over the casting /immerse in hot water and the dowel will pull out with pliers,same as removing gudgeon pin from a piston.Simples
What purpose of dowel pins
Mantap
все по кайфу брат!
Can use a tap inside the dowel pin and pull it. Better to replace pins anyways
Muito bom os seus vídeos... Parabéns!!!

A lathe is a stadart in a workshop
Si lo calentabas desde un principio salia igual con la pinza
out of curiosity and i mean no disrespect with the following comment, if you feel so, please know it's not my intention.
i love your work and i love how you resolve issues with great tools.
but isn't it easier to make another dowel pin? the time spent making tool is much longer than making a dowel pin (which is simpler shape).
cheers mate
Once you make it and then you still use it :)
Thanks for watching.
Why not use a Blind Hole Bearing Puller?
I have a lathe and mill as well. Way faster to just rip dowel out with pliers and quickly machine a new one. Time is money.
Обжимка?
wow
put the water pump pliers in the vice
Use a chissel and hit it flat from the side all around and great it free from the outer, collapse the dowel onto itself, they always pop right out within minutes.
Ok
Done subscribe...
Берем гайку с резьбой нужного диаметра прорезаем турбинкой и имеем такое же съемник...
Been doing it for decades with a dowel and vice grip. Works every time. Cheaper and faster too!
muy bueno pero no tengo torno jaja
Hat for?
@Paul X Do the dowel's come out of the tool easily?
Better than from the cylinder head ;)
