Tapping In - The Secret Machine Shop Skill!

[@tonywilson4713]

1/2 an hour on hitting things with a hammer??? Worth every second👍👍👍👍👍👍👍👍

[@TCB031]

Quinn, you are truly a gifted teacher. I've enjoyed all of your videos over the years, but your "Skills" videos are a particular favorite.

[@150flyer4]

Wow!! That was an amazing amount of tapping without making a single threaded hole!!

[@rickkucharski3211]

Having been a machinist for 40-plus years I've been using these techniques for a long time but until now never understood why they work. We just did them. We would just see some older guy doing them and follow their lead not bothering to ask why. Good job with the explanations. Very easy to follow what you were saying.

[@shadvan9494]

when i was in high school i took a machine shop class, we used hammers that had lead faces on them for tapping in vices and material. Lead is extremely soft and heavy, so a lot of force was not required. the best part is we made a mold so that when they wore out or started to mushroom out, we could unscrew them and the melt the lead down again, pour it in the mold, then drill and tap new threads in it and then reattach it to the hammer. me made most of the faces out of old tire weights.

[@oldfarthacks]

A very good method.If you want a harder face, you can also drop a blob of a harder metal such as copper or bronze or steel or titanium in the mold.

Knock off or knockoff nut - a winged nut to hold the wheels on

[@firebird8600]

​@oldmaninthecave I've heard both. First time I heard "suicide nuts" was when I worked at a tire shop where a guy had his knock-off adapters on the wrong side of the car when he brought them in. The shop old guy started yelling at the guy due to the risk of the nuts coming off that way.

[@shadvan9494]

@@oldmaninthecave I restore old cars as a hobby. mainly Second Gen Camaros. but I do love the classic European cars, like the 1957 Mercedese SL300 gullwing, Farrari GT 250 Berlinetta, and British cars, like the MG's, Asten Martin, and Jaguar's the XKE are particular favorites of mine. Harry Haga (the designer of the first and second gen camaros) used a lot of Eruopean Design cues for designing it. in particular the long hood and short rear deck of the Jaguar XKE. also, the 1970-73 Camaro with the Rally Sport option package has split front bumpers like the XKE, 250 GT, and Asten Martin DB5. You can also see the fastback and rear hip influence from the Farrari 250 in the second gen Camaro as well. I always had a thing for Knock Off wire spoke wheels. I have some pictures of an early second gen Camaro prototype with Knock Off wheels. Of course, GM being run by the Bean Counters, they said no to real knock off wire wheels. but they did offer a hub cap that was a wire wheel look-a-like. Anyway, back to the subject of Lead Hammers, I have a couple that i use on a regular basis, mainly for assembling thing that require a tight fit, but not marring the finish. they are also useful for seating thrust bearing on a small or big block Chevy. they also make a good piston install tool for driving the piston out of the ring compressor and into the block. I hold the head of the hammer in my had and use the handle to tap the piston in. the added weight from the lead makes it very easy.

[@dougkapounek9024]

A light bulb just went on.....Thank you so so so much. I was ready to throw my vice into the pit of never-ending darkness because I was trying to set up my vice and every time, well we will not enter the colorful words that were spoken. You are my "Heroine" ! ! ! Thank you again Quinn for making a novice like me finally understand. Your Queen of the Shop ....

[@FiniteEntity]

As a vicarious machinist (I currently don't have a shop, maybe I never will... I'm a temporarily or permanently embarrassed machinist), my goodness you are the best at teaching.

[@stoopsartsunlimited]

23:08 The more you hit on it, the less action. Yes, that aligns with my experience in many ways. 👍👍

[@les6516]

Thank you so much. I never knew there was so much to tapping... I am rushing off now to make a copper tapper.

[@thatspiderbyte]

don't think I could ever actually do any machining for health reasons, but I love learning about it & your videos are so interesting & informative!

[@timhooper8617]

30 mins on how to use a hammer? Worth every second! I saw lots of things I've been doing wrong, and how to rectify/avoid them in future.

[@ToBeeOrNotToBeHoney]

You just answered a question I always wanted to ask but was afraid to, snug then tap. Makes so much sense once you explain it this way...

[@myway9804]

The vice alinement was new to me , as you said expertly moving a part in you Hand gives you an idea of the different angles it creates . THANK YOU .

[@dweijers2193]

good teachers are rare to find, good job, well done, thenks

[@donaldsutherland244]

Yes! There are so many simple techniques to learn, and, thank you for explaining the principles! -and giving us the vocabulary. Impact force. I had never thought of the concentration of energy through the application of short duration as opposed to a constant effort. It is obvious, after it's explained and demonstrated! I will now have to learn to dial in my vise, as you have shown! Again, as always, thank you for being such a generous Quinn!

[@dziggy3004]

As a novice, I haven't had to think about these items, yet! It's so obvious AFTER you explain it -- but I'm sure I would have overlooked the "offset" pivot technology many-a-time before figuring it out! Thanks! Not as FUN learning it the EASY way -- but definitely will save future frustration!

[@ObservablePhysics]

Great video in an excellent playlist! The "impulse force" bit deserves a bit more detail, lest anyone think there is any mystical "magnification of force" happening. The two cases (teeny primate muscles pushing on the hammer vs those muscles swing that hammer) are very different: Case 1: Machinist pushes down on stationary hammer. Force applied to nail = weight of hammer + contact force applied by machinist to hammer. Case 2: Machinist applies a contact force to the hammer to swing it. Hammer accelerates. Moving hammer later hits nail and applies a different contact (impact) force to it. a) Contact force applied by machinist to hammer + weight of hammer = resultant force = mass x acceleration of hammer. b) As long as the machinist applies this contact force, the hammer's acceleration continues and the downward velocity of the hammer increases. Just allowing the hammer to fall achieves this, since the weight of the hammer alone is enough to accelerate it. c) Momentum of hammer = mass x velocity. d) When the hammer hits the nail, its velocity will become 0. So will its momentum. The hammer might even rebound (with negative velocity, experiencing even more change of momentum). e) Impulse = force x time for which the force is applied. Impulse is also equal to change in momentum. The hammer's loss of momentum is equal to the impulse applied to the nail. f) The collision between hammer and nail happens in a very short time interval. F = impulse / time, so the hammer exerts a large impact force on the nail. This is the "impulse force" referred to - it isn't a magnifed version of the machinist's contact force, rather it's a completely different force, caused by the hammer's sudden change of momentum upon hitting the nail. In Case 1, with no momentum involved, that doesn't happen.

[@maxinlux6570]

Absolutely fascinating video. I own NONE of the machines that you have, and know abolutely nothing of the stuff that you do- I drive a desk in a bank to earn my crust and pay my mortgage and feed what's left of my family (kids are at Uni, they're fine)- I stumbled upon your channel 2, maybe 3 years ago, love the mechanical stuff (steam engines and such), but this particular video explains so much, even if I will never use the info- Thank you!

[@caseytailfly]

I think what you are saying is that I need to engage impulse power before the warp drive. Got it, Scotty

[@acheide]

I've had some good teachers over the years. You are with the tops.

[@injoelsgarage3934]

Quinn, Thank you for your time an an unload of knowledge for a bonehead. I need to watch this several times. Play a panio? The more you practice the better you get. Pulling my vise off and doing it. Whoo too. Thanks again Quinn your the beat teacher. Joel

[@aaronprice1497]

I think this is the earliest I've ever been to a blondiehacks video less than an hour.

[@kensherwin4544]

23:55 "This method only works ahead of time." I wish I had known this 60 years ago on SO MANY topics!

[@DavidCookeZ80]

After learning how to tap things in on a machining course and being surprised about the precision achieveable with impulse force I've found many other applications. The most notable win is against the temperature control for the shower head - just with a finger, but tappy-tap-tap is the way to get the temperature you desire.

[@MrPallingo]

Your skin and hands are quite clean for a machinist ! Teasing aside, your lessons are absolutely deep and complete, leaving no question unanswered.

[@Kim-kl5jh]

Great video! I love how you explain things - you break it down so clearly and simply. Thanks for taking the time and sharing this video with us.

[@johnapel2856]

I always enjoy the basics lessons you show. I always pick up something new. Thanks, and Meow to Sprocket.

[@sherbertstrawberries]

Brilliant - VERY well explained, Thank You

[@yagwaw]

Definitely helpful, thanks a lot, Quinn.

[@lindonwatson5402]

6 seconds but 30 minutes 43 seconds?? foreshadowing quinn enjoymentage

[@claytonecramer]

Well worth watching. I wondered why my parallels would often slip out while milling and my results were never quite as square as they should be.

[@TommyWyche]

Your videos are very informative and helpful. I am an amateur, just trying to make my parts and tools. You put things in simple terms that everyone can understand. I didn't expect to find this good quality of videos on KZbin. Thanks!

[@Ranger_Kevin]

That explanation of the offset-problem was really helpful, I always fall for that because the damn vise mounts are never in the same plane as the fixed jaw. Somehow, in my head I was always thinking it was pivoting somewhere like 2/3 of the way down the length of the jaw. Thank you.

[@pingwax.]

Cool topic, very helpful for visualizing what's happening. This is another one of those things that seems trivial until you actually have to do it yourself; this is a nice reference!

[@AmateurRedneckWorkshop]

Nice instruction. Thanks for the video keep on keeping on.

[@gbalock]

Great video Quinn. The timing is perfect since my lathe and mill will be arriving in a couple months.

[@jeffpalser4928]

very worthwhile episode. Not just for beginners!

[@kevinmullner4280]

Gütentight. The first word i learned in my life. Kudos from good old Germany.

[@N.Cognito]

I learned to indicate my vise from Tom Lipton at Ox Tools, you did a very good job explaining what happens when you tap in a vise.

[@linmal2242]

Tap, tap. Yes as an old woodbutcher who used to make jigs for overhead router jobbies, little adjustments were always the go. Used to machine components in special wood components to thous ! Had to be special wood and home made jigs ! And production of thousands per hour, manually!

[@linmal2242]

And shimming and tapping our router bits to get size on the holes that we were boring, fast!

[@rickstirling7045]

Excellent presentation. Well done!

[@giacomo7625]

I haven't watched your video for a long time, and now I can see a huge leap in quality. I find the sharing of your experiences valuable, with a detailed explanation of the dynamics: causes, effects, precautions, remedies and strategies: All very clear and understandable: it is very useful to me. Thank you.

[@Si-Al-Ti]

Hi Quinn! 😊 I'm looking for other machinist KZbin channels run by women, since I only know of you. I thought maybe you would know some? I'm not really trusting the search function and algorithms here on KZbin to find exactly what I'm looking for. There are so many talented female makers and woodworkers on here, but so far, I've only found one (yours!) who's main focus is machining. Thank you so much for all the great build series and lessons on technique! Really appreciate it

[@Sparweb_Projects]

I seem to picked up some of these tricks over the years, but nowhere near your level of skill. And I could never explain it as thoroughly as you can. Thanks & Love your channel!

[@johnsherborne3245]

Setting the vice true ; very impressive indeed. Thanks for a really useful tutorial.

[@joergengeerds360]

as a suggestion, if you put your finger on the DTI tip, you can dampen the hammer impact on the dti

[@bobhudson6659]

Try doing that and then take your hand off the tip - without taping or moving anything else and see where the needle rests the 2nd time around. But I also tried your suggested methods years ago - without success. Also need really small fingers/really delicate touch - small fingers I don't have but sometimes OK with the touch. Retired machinist in Land Down Under.

[@joergengeerds360]

@@bobhudson6659 when I'm in my shop, i can put the finger on the DTI and it will not move, and will stay put at it's current reading (0.01mm and 1/10th DTI). finger on/off doesn't change the reading. hence it it a great way to damped the impulse from the hammer

[@avoirdupois1]

Important tips! Thanks for the overview.

[@LadyDewBuild]

I have learned so much from you, but alas I sold my lathe and mill for, reasons. But still love your great ability to teach

[@Farmerupyonder]

Great video! Thx for clearing up so many questions in one consice video.

With proper skill and application even a hammer is a precision instrument

This is an excellent video. Something after nearly 50 years of machining (and teaching) I’ve never heard of before! One question: what do you mean by the term “delta“?

[@donaldknapik2706]

Great video! These are some of the same skills I’ve used setting elevator main rails in construction and tramming motors in repair.

Fantastic explanation of the tapping in process thank you for the education Cheers.

[@knucleon8483]

I always learn something new in these videos - I wouldn't have thought to use rapid (or on my little CNC, a slow move) to tap the vise in real time. I usually just jog dial back and fort with the DTI but this might save me some time!

[@funkbungus137]

lol, growing up helping my uncle on the farm he used Gutentight as his standard for how torqued down something had to be on this or that piece of equipment.

[@TheCubefreak14]

One comment I want to add for squaring up the mill vise. If you're brand new to it, when you get the vise on and the bolts into the slots, pull or push them tight up to the slots in the mill table. This can limit the error that someone whom is not used to walking a vise in and potentially make it easier to get it dialed in. This was a trick one of my instructors had taught me. Great video though Quinn! Also, why is your lathe trying to be in the blue man group? 😁

[@tkat6442]

Thank you, thank you, thank you!!! I have a particular application for what you just taught me in this video! I'm in the middle of a vacation trip now, but as soon as I'm back home, I'm going to practice the techniques you've described here, and I will be a better machinist as a result! Video saved!

[@tkat6442]

Btw, I just tried to do a search to see whether or not there are other videos or articles on line about this topic, and I couldn't find any! Idk if I used the right search words or not, but all I could find was information concerning creating threads in a hole.

Well done a wealth of info presented planely. Thank you.

Thanks Quinn

[@denniswhite3487]

Wow. Great practical knowledge that saves me time I learn this stuff very slowly without input like this. Thank you!

[@garageofpower2891]

A lot of the finger type indicators have a lever that you can use to flip the direction of the indicator tip, which will take it off the part.

[@oldfarthacks]

You can also slip a shim of a soft material, such as a couple of layers of paper towel between the part and the indicator.

[@jbrownson]

I looked for this video when I started machining a year ago or so and couldn’t find one. Thanks!

[@garyf5192]

Really fine tutorial.

[@Rangemaster26]

You might want to try making a hammer head out of lead. Lead has absolutely no bounce and being heavier it takes only a very subtle "tap" and being soft it won't mar your work. Sure, it will distort faster but if you take it easy on them they'll last for quite a while. And when they get really ratty, they're easy to make and you can use the lead over again to make another head.

[@toddkerns4493]

Wow, that was a brilliant video! I learned a lot.

[@bobblankenship9544]

[@BeeGeeTheImp]

This is an excellent tutorial. Thank you.

[@WestHamBubbleBoy]

Wow thanks for that tappy tap tap lesson Ms Blondy. I won't be thinking of sheep tonight.😂😂😂 Just kidding. I appreciate the way you explain in such detail everything you do. I also like the fact that you show us when a mistake, an error, a moment of lost concentration is made. For example, were you thinking about that open cupboard, screaming, close me, close me please, I feel exposed when you made that error? 🤭

[@orbatos]

I've had something very similar happen in university systems, not something I wrote , but there uphill battle to get management to engage with the use was a hell of a headache.

[@jimlock3514]

Excellent! Thank you!

[@nelsonbrum8496]

I prefer using deadblow hammers with replaceable plastic heads to tap down parts. Less bounce to the hammer, less tendency for part bounce. I prefer the Lixie brand, I have light aluminum and heavy cast heads in 1" and 1.5" sizes.

[@TonyMotana_]

Could you do a video on the use of bore micrometres and how to read them?

[@Hossimo]

I don't even machine but love watching your every week videos. As soon as I have some cash and a little space in the garage; I'm going to need more cash. It might have been helpful to visulize jaw lift with an indicator on the 1x2x3 block?

[@tomcook5813]

I prefer lead hammers, that’s another fun part of the hobby, many facets of interest 😊

[@exapod23]

Question about the lathe tapping: if a "light" tap moves the part, is it possible that the cutting forces will move the part out of alignment?

[@marknerren402]

This is awesome. Two things indicated in one week!
