PROCUNIER TAPPING HEAD What Makes It Work #31 tubalcain

[@ThisOldTony]

I enjoyed that Mr. P! Keep 'em coming.

[@mrpete222]

Thanks

[@johngubler1260]

don't you mean LP... great christmas story, Thanks!

[@jimc4731]

An excellent video, Mr. Pete! That device tapped hundreds of thousands of holes in my production shop over 50 years, trouble free. No rebuilds necessary!! JIM

👍👍

[@MrPatdeeee]

Been looking for decades at advertisements of this "tapper" thangy. Didn't think much of it UNTIL our "Mr Pete" showed us how it works and how great it is. Now many will "wonts one". You are a "gem of gems" Lyle. May He continue to "gift" you with "thangs" that make this DIY video amongst the bestest of all of 'em! Oh indeed yeah! Whoeee!

[@mrpete222]

Thank you very much, I needed that

[@MrDdaland]

You come up with some of the most interesting tools that I never dreamed existed, but upon seeing them I can see their utility

[@mrpete222]

👌👌

[@Motor-City-Mike]

You'd be amazed at some of the tooling used in the past in the machining industry. One thing not too often realized - every type of machining now done on CNC machinery was done long ago on strictly mechanical machinery - by true craftsman.

[@michaelcerkez3895]

First thing in the morning to wake up to Mr Pete and a cup of coffee. Great way to start the weekend! Thanks Lyle the last couple of series have been great.

[@mrpete222]

Thanks

[@tropifiori]

Yup

[@dannyl2598]

Thank you for unraveling that mystery. I think you did an excellent job explaining that. In the beginning when you where telling how it operates I was imagining a stack of disks like a clutch, then I was amazed that it was even simpler. Kind of like opening an Easter egg. Thanks again.

[@mrpete222]

👍👍

[@Motor-City-Mike]

Some other brands of tapping heads did in fact use clutch disks! Some are/were even adjustable for clutch tension so torque to the tap could be limited - Tapmatic still makes just such a tapping head. There was plenty of "magic" in the history of machining/toolmaking!

[@dannyl2598]

@@Motor-City-Mike that so cool. Thank you for sharing that information. Happy New year.

[@Motor-City-Mike]

@@dannyl2598 absolutely! A happy and prosperous new year to you!

[@neverendingstudent]

Thank you good sir. I bought one of these at auction with the idea to resell it and didn't know how they worked. Now, thanks to you, I do and was able to test it. Much appreciated.

[@brucekiszely2995]

Neat tool, I will add this to the growing list of garage sale goodies to stalk!!, Thanks Mr Pete, 👍

[@brucewilliams6292]

What an elegant design. Thank you for the videos! Happy New Year.

[@zacharyrowe8395]

I have used these for some 20 plus years and always wondered how the worked inside. We always had a tool crib guy that would service them so i never got to see inside. Thanks for the video made my day

[@mrpete222]

👍👍

[@andyZ3500s]

Thanks for showing this to us. Looking forward to the servicing video. Now I won't be so nervous about picking up a used one. If anyone spots one make sure it has all the collets most don't. That is for the ones that were not paying attention in class!

[@mrpete222]

👍

[@aaronleiter9009]

Thank you for this video. I always wondered what they looked like internally and how they operated.

[@Watchyn_Yarwood]

You did an excellent job of explaining how it works! No need for a cut-away. Keep up the interesting and entertaining videos!

[@mrpete222]

Thanks

[@chakathewolf]

We had those in the shop at Texas A&M University. I fell in love with them! I wanted one for my own shop, but was driven back by the sticker shock.

[@PaulSteMarie]

Stalk eBay for them. If you can use a Morse taper, it will be easy, but the ones with 1/2" shank can be obtained at a moderate price if you wait long enough.

[@mannys9130]

Hey LP. 😸 Glad to see you got a ride. That's a very interesting tool I had never seen before! Hope you had a Merry Christmas and I hope you have a happy New Year.

[@craigsudman4556]

That is a fine machine Lyle, I love taking apart old machines like that...they don't make 'em like that anymore. Great video, thumbs up.

[@jodydoakes8754]

Very interesting. Keep 'em coming. Many of the old JD two cylinder tractors had a cone clutch similar to that.

[@electricman5010]

Thank you Mrpete ! ive used the Procunier as well as the tapmatic tapping heads over the years, both with excellent results. The tapmatics can be found quit often on radial head drill presses.

[@vipertech9108]

Awesome tool design! The designer was a genius. Thanks for showing how it works Mr.Pete!

[@mrpete222]

Yes he was

[@tano1747]

Perhaps a housing incorporating rigid transparent plastic tubing would be less messy than a cut away and would allow you to still use it as a tool?

[@brianday6433]

I've been a machinist most of my adult life. And I have always wondered how those tapping heads work. Never had the chance to take one apart. I knew it worked on clutches. Never thought about a cone shape. I envisioned a double sided flat clutch. Never thought about Cork as the friction clutch either. I always wanted to build my own version, maybe smaller diameter. The great thing about the Procunier is the ability to stop or reduce the pressure while tapping hard metals. Saving broken taps in the work, Ugh. We have a Tapomatic at work and I never use it. Thanks Mr. Pete!

[@mrpete222]

Thanks

[@Blue.4D2]

Very clear explanation. Surprisingly simple mechanism. I love gizmos!

[@cojones8518]

Made perfect sense to me. Good explanation of how it worked, so don't worry about a cut-a-way.

[@mrpete222]

Thanks

[@dannywilsher4165]

You're right Mr. Pete, very ingenious!! Good job on your explanation.

[@mrpete222]

Thanks

[@russelallen5342]

Very interesting. Never took one apart, but used one a LOT, when I started at the machine shop!

[@RRINTHESHOP]

Happy New Year, Great demo. Nice unit.

[@normpeplow3813]

In early 60's i worked for Supreme Products and we made a tapper similar to this for drill presses; also a push-pull tapper for use on hand drills. Both used planetary gears. I was line supervisor for assembly for a while. Very interesting to see this again.

[@mrpete222]

Thank you, I remember those supreme tapping heads

[@blobscott]

Great video! To add to the explanation on how the tap direction gets reversed: Reversing to counterclockwise during tap removal is due to the ring gear (connected to drill chuck) driving the sun gear (connected to tap via cork clutch) through the planet gears (fixed to tapping head housing). In this configuration, the sun gear rotates the opposite direction of the ring gear. Pretty neat! The planetary gear set provides the increased reverse ratio, but also is responsible for reversing the direction of the tap.

[@MrShobar]

Well that brought back some memories. Thanks. I was eighteen when I was first introduced to this great labor and time-saving device.

[@mrpete222]

I never saw one until I was 21. And then I was amazed by them

[@rossbryan6102]

I HAVE HAD TO USE A PROCUNIER SEVERAL TIMES! LIKED THEM VERY MUCH!!

[@stewartalbert3523]

There are pneumatic gun tappers out there , depress trigger half way for forward , depress trigger full for reverse . A little tricky to use and probably expensive .

[@nevetslleksah]

Very interesting. Thanks for making the video. Thank goodness for inventors.

[@ErnieNoa3]

I always wondered how it worked. Thanks for taking it apart and showing us what is in there. I was still in Highschool when I worked in a summer job in a machine shop and had to use one. All was fine until one of the kids broke a tap and we were all fired. I only worked there for a day. My only machine shop experience.

[@donaldnaymon3270]

Great video. Great description of how it works. Thank you for sharing

[@28gwdavies]

A very interesting video yet again Mr Pete, it's funny, I never thought that at 65 years old I would still be listening to and learning from a shop teacher. Funny old world. As a teenager I had a choice of careers. I was offered an apprenticeship at British Aerospace as a machinist/toolmaker or an apprenticeship as a TV engineer. I chose the latter and yet in retirement have gone back to machinist as a hobby, I may be your oldest student!

[@mrpete222]

Thank you, I’m glad you like my channel. I think there are other is much older than you that are watching. LOL

[@BentTreeFarmPa]

Wow that is interesting. When it is broken down, it is actually not that complicated, but was probably very ground breaking in it's day!

[@mrpete222]

Thanks

[@SalvageWorkshop]

I loved the different intro for this video! I just picked up a tapping head that looks very similar, but I think it is an ETTCO, not totally sure, but I cant wait to give it a shot!

[@bcbloc02]

Planetary gear sets are awesome.

[@mrpete222]

Yes

[@robertoruiz7069]

We had two of those at my work place that i used and serviced for 25 years.They where on a 5 position quadrille head.we put a drill ,a 82 degree chamfer,a counter bore,and the taping head.Once you use one to do a bunch of holes you wonder how you ever got by without it.They are fantastic and worth way more than you pay for them. That was the best explanation I've ever seen ,with a tool I'm very familiar with. thanks

[@mrpete222]

Thank you, I’m glad you liked it

[@AmateurRedneckWorkshop]

Great video. That Procunier has a lot less parts than my Tapmatic which has at least twice as many parts. Mine has a lot of clutches and clutch springs and gears. It was broken when I got it and I took it apart to replace the broken part and it was hard to get back together.

[@mrpete222]

Never had a tapmatic apart

[@elsdp-4560]

THANK YOU...for sharing. Watched and very much enjoyed.

[@mrpete222]

[@dragonrider93]

Love these vids when you take stuff apart. Back when I was a kid, curiosity got the better of me and I took a lot of stuff apart to see how it worked........ Merry Christmas and Happy New Year !

[@mrpete222]

My dad did not believe in buying toys for us. He would give us mechanical things to take apart. Now that I look back, that was a stroke of genius on his part. I was jealous of friends that had lots of toys.

[@MrUbiquitousTech]

Very neat engineering, sure had some smart people developing neat inventions back when. Thanks for sharing!

[@mrpete222]

Yes thanks

[@TheAyrCaveShop]

Enjoyed...always wondered what was inside of those

[@ralphgould2783]

Always wondered what was inside! Thanks Mr. Pete

[@lenlandrum4229]

I have one of these. It has a one half inch capacity. I've not use it in quiet awhile. I should get it out, clean it up and see if I could get up a trade with s local shop that might could use it. I no longer do production in my shop. I'm retired and just play in my shop.

[@prenticeemler7709]

Thanks for sharing, I bought a used one on eBay, and after using it I wondered how it works , now I know ,thanks so much for your videos ,they are very useful.

[@terrystover7365]

Always wondered how they worked. I've used them but never disassembled one.

[@pierresgarage2687]

Nice to see what's inside and how it works, very simple in fact... That saves me from disassembling mines unless they stop working... 🙂👍

[@mrpete222]

Yes

[@seekingtko3146]

same tool i used to drill Aluminum parts worked great no stripped threads

[@jordanparkinson4584]

Well explained ! Always wondered how they got the 2 x reverse Drive !

[@pdaddyblake]

Mercusier still uses friction cone drives in there bravo outdrives learned about them when I serviced mine they dont make as much noise going from forward to reverse as dog type gears👍

[@SteveSummers]

Thanks Lyle. Very interesting design.

[@Bennybob01]

Thank you for this video! I’ve always wondered how these work so you answered a question I’ve had for the 13 years I’ve been working in the trade!

[@MrFHLH]

Thanks, often wondered how they work, now I know, clever. Just wondered have you heard of a Mill Master milling machine, I am told they were the fore runner of the Bridgeport milling machine.

[@mrpete222]

Have not

[@johneric3886]

Greatwork Mr. Pete, I actually use one of those we did a huge roll tap Job. Most of our machines however are Brown and Sharpe.

[@JamesDedmon]

Interesting how it works, back when I had hair, in the first shop I worked in we had a tapping head in a dedicated drill press. In fact we used it on gears that had set screw holes in them. So being an apprentice I did a lot of tapping. Thanks for the close up of one of my modified oil cups, you did that to see if I was watching 😆

[@mrpete222]

👌

[@michaelcoceski5442]

That is such an ingenious tool, thanks for sharing.

[@kennygee6627]

Thanks! I’ve use these many times but have never been inside one. Since I was a little kid I’ve enjoyed “how it’s made“ or “how it works” type videos. There was a show in the late 60s, early 70s where they pick some random kid to reach into his pocket and see what he’s carrying. Then, they would go through each item and go to the factory and show how they were made. Marbles, jackknife, chapstick, even a piece of paper. Interesting 👍🏽

[@mrpete222]

Thanks

[@randyvilleneuve4907]

Always wanted a reversing tapping head (its hard to tun a drill press by hand) so i bought a Procunier 2E off e-bay for $140. Came with a 3/8" collets but those collets are expensive. I got 6 off e-bay for another $75 so not too bad. Have not used it yet but looks to be in good shape and its made in the USA. Thanks for the video.

[@mrpete222]

👍👍

[@railfan439]

Lyle, the old guys with the circular saw mills used a similar idea for moving the shuttle back and forth. They had a spinning disk with a wheel that would move to one side or the other of the disk, thereby reversing the shuttle movement. See you at the Bar-Z. Jon

[@justinbudreau4814]

I have been looking for the name of this device for three weeks. Thanks Pete! I saw it on a tapping/drill press and haven't been able to find it since.

[@AWDJRforYouTube]

Great unit, can't wait until your service video. 👍👍👍

[@elcheapo5302]

Ingenius! Thank you, Mr. Pete!

[@bking0740]

Do you have any videos of cutting a inside ring gear?

[@user240485]

hmm possible future shop project I think DIY tapping head. The friction fit would have to be replace with some sort of full gear system. It would be tough to create and it would have to work on the principal of a manual transmission but scale way back with only one speed. Thanks for butting another shop idea in my head.

[@Motor-City-Mike]

I have no idea of what you have available in terms of materials or machinery but the clutch drive could be duplicated using Nylon or a plastic with characteristics similar to the cork (there are quite a few) for the clutch cone itself. Of course if you'd enjoy developing a small, reversing gear train feel free to ignore me, lol!!!

[@scotttipps8155]

I have 2 of these given to me by my old shop mentor. Unfortunately they both have Morse tapers as opposed to a straight shank and I can't use them. Thanks for the inside view

[@mrpete222]

👍👍

[@Dancer148]

Thanks, I always wanted to know how that worked before buying one. Allthough my handtapping gets jammed frequently and multiple reverse is needed I wonder if the small taps won't break with that tapping tool.

[@ohmbug10]

Thank you for the awesome video Mr. Pete. I would have loved one of these for the countless machine screw holes I made on industrial electrical control panels. 😀

[@mrpete222]

👍👍

[@paulinmt2185]

I'd love to find one of these. It might keep me from busting so many small taps ;-) Thanks for the look-see.

[@mrpete222]

Yes

[@ronaldkearn3322]

That video was super! What a fantastic tool! Can you imaging that tool in some factory just tapping? Worth its weight in gold.

[@jerrywilson9730]

Keep them coming, always enjoy! How could you get 11 thumbs down???? Some people need to get a life!

[@mrpete222]

Lots of nasty people out there

[@German_MDS]

Very clever device. I wonder how well that cork will hold the cones in case of the tap getting stuck in the threads. I asume it would have been a consumable part.

[@stevewalker7822]

What a very unique tool.

[@michaelcraig6408]

Doesn't the cone have to be offset a little to catch the cup and reverse it?

[@GaryT1952]

Fascinating Mr. Pete, thank you

[@joeheilm]

Very interesting! I would have never expected cork. Great stuff. Cheers

[@miken3260]

I bought what I thought might be a tapping head very cheaply at a flea market. It had the arm coming off it to stop against the drill press column. It turned out it was only a speed reducer and was too small for drills with over a 1/4 inch shank.

[@V8Lounge]

I've never seen something like that here in germany. Very interesting. Thank You for the video.

[@danedewaard8215]

Truly amazing! Thank you for the excellent video!

[@mrpete222]

[@vecair]

Whats going to keep those two pins you tapped in to the tube with the acme nut from working their way into the tube over time? They will do that.

[@piccilos]

I have one of these, the collet but on mine is extremely difficult to remove

[@mrpete222]

Thanks

[@jonhare392]

Thanks Mr Pete!

[@barlowchiro]

So you can just put one of this in your drill press chuck? You don't have to remove the chuck and install this?

[@Bronco541]

an ingenious piece of machinery; excellent series too; I love learning how stuff works! 700$!? that's a bit much (for a new one)... much more affordable to either buy used or just go the old fashioned handheld way... Hell you can buy a brand new drill press for that price (or less even)

[@mrpete222]

Yes, I would never buy one. Way too much money.

[@BiddieTube]

I have at least one of those, not sure what brands or sizes. Have always been afraid to use it because could not understand why the tap does not brake in the event that tapping becomes too tight. From this video, it appears that "Tapping Torque" is determined by how hard one pushes down on the drill press handle, and if not pressing too hard, when the tap gets too tight, or bottoms out in a blind hole, the cork clutch cone will slip. I am sure I got it, but if you read this, PLEASE Confirm. Now, when those heads turn up, lost in the crib somewhere, I will put them in the shop and give them a try on "Government Work" until I become familiar and confident in the feel of using them. I will dissemble, inspect, clean and lube them before using since now, thanks to this video, I completely understand whats inside and how it works. Thanks :)

[@mrpete222]

Yes, you are right

[@RetroSteamTech]

Thanks Mr Pete. Never seen one of those before, very interesting 👍

[@PeterWMeek]

Looking forward to the "servicing" video. I have one of these and it needs servicing. I hope I can get away without replacing that cork cone.

[@mrpete222]

Yes

[@Smallathe]

Very interesting!!! Happy new year!!!

[@dan-og1hd]

I have always wanted to see how these things work, I've used old Japanese ones in the past and now I use a Tapmatic, it"s surprising the revs that these things will run at

[@mrpete222]

Yes 👍

[@keithparady2594]

How hard would it be to make one of those

[@danballarin]

I got one of these from my work because they were going to throw it away! Unfortunately I think all the collets did go in the trash!!! they are about $45 a piece, so I will have to see about making my own adaptors.
