ADAM I CHALLENG YOU TO MAKE A ARTICIAFIA INTLLIGANCE

[@Die-CastMetal]

I love taping holes however my favorite tool in a shop is the file...metal file specificity.

[@richardhjones5576]

You remind me of myself. Your enthusiasm and excitement for things mechanical. I felt that as a boy when first started to build soap box racers. And it has continued through my whole life. On occasion when I expressed the feeling to others I was looked at and often made to feel I was a bit odd. But here I am at 77 and still getting the jizz when building things by welding or mechanical fastening. At the moment I am about half way through building a log splitter from scratch. Earning a living through life after getting out of the Navy I was both a carpenter and a steel fabricator as a welder. But I know at the age of about 6, that what ever I ended up doing in my life I would be building things with my hands. That came from the great joy I got from playing with my Erector Sets and Tonka Toy sets I got from my Grandmother for Christmas. I raved about them so much to her she got me one more each of both of those. I was then in heaven cause I was able to build huge projects. I over heard my mother complain to my Grandmother that I did not do well in school work but for math. My Grandmother told her "Don't work, Between his math skills and his talent with his hands he will do just fine." By the way thanks for the tip. I will be making myself a set of Thread Tapping Guide Blocks

So, Jamie has been in quarantine with his dog and his wife, and if you watched Cabin Fever, you get a sense of how he's faring with the isolation. (In other words, he's doing well: exercising, reading, working, streaming, etc). Jamie and Adam speak occasionally, like they did when Grant passed away. But otherwise, Jamie is happy to be away from filming, and that does include Tested.

As Adam is fan of the saying; "Less is more.", I feel it needs to be said that in terms of pressure in tapping, less is indeed more. However with the tapping fluid, more is definitely more. I really enjoy listening to his wisdom gained over a lifetime of doing "maker work". This information is gold.

[@leonhostnik9516]

2 things that are best practice in my industry: always have 2+ of any tap you want to use, and if you drop a tap on a hard surface from table height, throw it out. Never be afraid to throw out a tap that might shatter/snap on you, that's what you have extra for

[@originalkhawk]

@No Akomplice the taps them self are not too expencive and you shouldn't drop them regularly anyway, but you would rather trow it out than start tapping a hole and have it snap, because either way you are going to have to replace the tap, it's just the diffrence in having to exctract the broken tap or not

[@leonhostnik9516]

@No Akomplice breaking a tap in something important is a nightmare. Yes, this is an industry practice, and might be excessive for your average maker, but a single new 8-32 tap is $4. Throwing away a 4$ tap to avoid having to spend an hour trying to pull out a broken one, or remaking a part, is 100% worth it to most people.

[@f123raptor]

No Akomplice Quality tools and proper care/disposal often represent a higher initial investment but one that ultimately ensures quality results and saves substantial time and material (money). That’s why people and organizations are willing to pay extra for them and to dispose of them readily if they’ve been compromised - because the tooling is almost always the smallest expense when the alternative means having to scrap a project and all of the labor and material that’s already gone into it. This is compounded when one considers the implications on a relationship with a client if a project is botched due to totally preventable issues with your tooling. Quality tools are expensive. Some can afford them, some cannot. In either case, one generally gets the quality they’ve paid for.

[@wolf310ii]

You have always 2+ of any tap, so can throw out a tap when it gets dull. The majority of taps snap because they are dull, not because they fell. If a tap has a crack, you can feel it during the cutting

[@treborrrrr]

@No Akomplice Buy once, cry once. That's a lesson that my brain is still trying to hold onto. Can't count the number of times I've bought a cheap ass tool only to have it break and having to buy another one (or mess up my work so I had to start over). Instead I could've bought a slightly more expensive tool that wouldn't break to start with.

[@davehughes7332]

"There's entire fields of study about this that really don't ever fall within the purview of making shit at home... but it's worth it to know it" - Adam Savage, 2020, perfectly encapsulating one of the many reasons I think he's an awesome human being. (I love his enthusiasm and his passion to make the world a better place, but knowing random engineering esoterica and knowing when you can just use 2 zip ties and half a roll of gaffer tape is just classic Adam).

[@devongronka855]

A lot of that probably comes from all the movie stuff he did. When you're doing stage crew and stuff, you have to think creatively about how to do the job adequately but not necessarily permanently, how to make repairs on the fly, how to build things that can be easily disassembled when the time comes (and possibly reassembled, over and over), etc. Doing stage crew for the drama club in high school was a lot of fun because of these sorts of things.

Adam, you’re always the effective teacher! One of the ways I describe the difference between coarse and fine threads when I’m teaching someone - the fine thread is like a lower gear in a transmission and the corse thread is like a higher gear. Fine thread = more input, less output but greater torque. Coarse thread = less input, more output but lesser torque.

My most commonly used size is 1-72, although I also use 2-56, 3-48, 4-40, even 0-80! It often cuts days off of the time for a repair if I can make a new part myself using raw stock or altering a similar part I already have rather than ordering a new one and waiting.

[@billzilinek3917]

Adam, today you were called my spirit animal.....let me explain: This weekend, I decided to fix an elevation problem with my table saw (starting a home shop after 35 years away from making anything). Turns out, the mechanism was fine, but the hand wheel was made of plastic, and its central hub stripped. Replacement wheels are cheap, but made of plastic, so I began searching for a metal replacement. I can't find one that has a center borehole that's properly shaped (in a D for my saw), so I decided I would look for one with a round bore. Then came the question of how do I attach it. Do I weld it? Never welded before. Do I drill and tap it? Never did that, either. The very next day, you published this video on tapping, and helped make my decision and boost my confidence in the procedure. Hence, a co-worker of mine has named you my spirit animal. Thank you for all you do to inspire and teach us all.

[@orien2v2]

I'm mostly dealing with wood so I've been holding off on buying taps. But since the other video I saw how happy Adam was having that "mechanical connection", I told myself I NEED to try it. So I bought a set, cheap stuff, and now this video is super helpful once I finally get it this week. Thanks for following up on this topic!

[@glennjames7107]

Careful! I don't know just how cheap of a tap set you bought but, don't let that cheap tap set ruin your veiw of tapping. The process of tapping can be made unnecessarily difficult by using poor quality tools (like quite a few other tasks). The hardest part of tapping should be starting the tap straight, at least when tapping smaller size holes like discussed here. If you run into anything else that seems difficult, it's probably due to tool quality. Of course you can have a tap from a reputable maker and if it's dull, or chipped badly, can give you issues.

[@johncoops6897]

My biggest tip is about the reversing of the tap. Firstly, look at how many flutes there are on the tap. Let's say a 4-flute straight tap, that means flutes are 90 degrees apart (3-flute is 120 degrees). You MUST reverse the tap very often, and also reverse far enough. OK, once you get it started, you only want to cut a maximum of 3 to 4 flutes worth of rotation, then come back out by 2 flutes worth. So, for a 4-flute, max 1 turn in, then 1/2 turn back.... go slow! The purpose of the reverse direction is to cut off the chip that you form on the forward stroke. It's the rear edge of the previous flute that makes that cut. So you must go backwards at least 1 flute-worth of rotation, which is why they say "1/4 turn back". However going backwards a bit extra is even better. The reason people snap off taps is that they force them in, and the long spirally chips cannot clear. So the chips jam up inside the flutes and the tap grabs then jams and snaps. By making tiny cuts then reversing, you create tiny chips like sand or powder, which don't jam as much. If you are going in a deep hole, then repeatedly remove the tap completely and brush or blow off the chips. Doing these things will result in you not breaking taps, even tiny ones.

It’s not very big. But has 6 tap hole sizes from 1/2” on down. It was used by several guys that liked it so well they had a guy do a Rockwell test on it. Take measurements and map out the hole placement for CNC. They made several. And really liked them. We milled two oval slots on each linger side for grippage and stamp your initials in before heat treatment. Ground them clean and square afterward. And done.

[@jmacd8817]

Awesome vid, as usual! Sometimes when I have a smaller piece like that acrylic or aluminum, and if being normal/perpendicular to the surface is important, I will chuck the tap into my drill preas, and turn/tap by hand. This works in a couple ways; 1) it keeps you perpendicular, 2, because you're gripping the chuck, which is smaller that most tap handles, you are less likely to "ham fist" the work, break the tap, etc.

[@wolf310ii]

Point 1, yes absolutley Point 2, no not so much, because you have to apply much more force to turn the spindle (depending of the size of the drill press), wich is especially bad for small taps, with a small tap holder you have much more feeling for the tap. Also the spring in the drill press is pulling the tap upwards, wich can produce tolerance errors (the tap cuts more of the thread flanks than it should)

[@Darwinpasta]

I've done this to start big taps straight in steel. It was kinda fiddly (the chuck key did not make a great tap handle), but worked much better than the old squint and hope routine. Once the tap was started, I removed the work from the drill press and did the rest with the usual tools.

[@wolf310ii]

@@Darwinpasta Bigger taps have usually a conic hole at the end, so you can use something pointy in the chuck as a lead for the tap, and a tap crank for turning the tap

[@AlexanderBurgers]

There's actually a special tool for that, a spindle tap wrench. it's like a regular tap wrench but it's got a telescoping end that goes in the drill chuck, that way you don't have to perfectly push down the quill while tapping, you can just let the tap do the work, but you do get the alignment help.

It is so refreshing to see learning channels like yours on KZbin, unfortunately there are too many of them out there which teach down right dangerous practices and people new to craft type practices aren't always aware of who is teaching them right and who is potentially leading them on the road to an accident. You have taken the time not only to show how to do it right but further explained the reason why it was the right way along with showing how not to do it. This is by far the best ever video I have seen on how to and how not to tap a hole for a threaded fastener. Kudos to you and good luck with this channel, I am now subscribed and will follow along. Kind regards and thank you from England UK.

fyi: A screw with more threads per inch is less prone to getting loose of vibrations, because the threads are less steep.

[@johncoops6897]

Yes, but a thread with more TPI is weaker in soft materials, so the threads can deform (strip) and it becomes loose that way.

[@kgsalvage6306]

Very cool. I never had anyone show or teach me how to tap. Been tapping for 40+ years. I basically do it the exact same way that you do. It's really common sense. It's funny how builders do things the same way, learning on there own.

two years late but i used to work in a machine shop with a good friend who taught me everything i know.. really, when it comes to tools and steel. 6 years later i've found myself as a technician at a museum and rediscovering things like tapping has been wonderful because i used to know how to do it! recently had to tap a piece of steel and remembered how much i enjoyed the feeling and doing it and have since wanted to set out to learn more on the subject and what to buy.. lately i've been spending hours watching your content as an old mythbusters fan and i see this video pop up!

I currently inspect taps that we produce at my shop. I work for a company called Tivoly up in Northern Vermont (plant actually sits right on the border of Canada and the US). We make so many different style taps from standard to metric, bottoms, plugs, and taper taps along with many specialty taps used for specific applications. I have to hand wire these to make sure the P.D is within tolerance most of which are within +/- .0005. I have to wire all the way up to 120 pitch which is very fine at 120 threads per inch. It's pretty awesome to see you explain this as many people do not realize the importance of these tools!! Great video Adam!

Quick tip if you're tapping a large hole: counterbore the hole slightly before tapping. It makes everything much easier

[@xenonram]

Counterbore? I think the word you're looking for is chamfer, bevel, or countersink. A counterbore is "a drilled hole that has a flat-bottomed enlargement at its mouth." (Definition from Google since I couldn't figure out how to put it into words.) It is mainly used to countersink the head of a fastener.

[@stevenpaige2005]

Glad I'm looking back at older videos. So many tips and ideas just, pooring out of this man

[@Die-CastMetal]

I’ve never successfully used a tap extractor as it was intended. I’ve always cut my broken taps out with carbide drills or end mills.

[@andy-in-indy]

End Mill for the win!

[@SeanCorriveau]

MA Ford Crazy drills were great for removing broken taps

[@Die-CastMetal]

I broke up a few taps before with a hammer and quality punch ground to a fine point. Not my finest hour but whatever works with the least amount of labor waisted. End Mill certainly is preferred when available, its all about location.

[@TomDetka]

We have a waterjet at work and have honed the art of cutting broken taps out of holes. Even works in blind holes is your careful.

[@kingfishj8]

The only time the tap extractor worked for me was *after* I had given up caring about the extractor tool itself and decided to (pardon the expression) go for broke. I was pulling a broken 4-40 tap out of a large aluminum baseplate. It bent and started shearing itself and just when I though the extractor was finished shearing off, the broken tap chunk gave and everything came out.

Also, cleaning the chips off at running drill bit at 36:09. If he had a really sharp set of drills like cle lines his finger likely would have gotten cut up.

[@xenonram]

@@CanDriveSoon Things that seem dangerous to the inexperienced are often inconsequential to a skilled craftsman. It's funny to see comments, from people not in the trades, on videos like this, where people think something is dangerous. It's like when someone puts their hand through a candle flame, or funds their thumb across a blade to see if it's sharp. People who are inexperienced with that kind of stuff freak out when they see it. Doing what he did isn't a big deal if you know what you're doing. Also, the flea of a Cle-Line set of bits isn't sharper than any other drill but set. The flute sharpness makes no difference. They're not doing any work besides acting as a bearing surface, forming a seal against the bore to ensure chips are carried up & out of the hole and not be pulled under the leading edge of the flute.

Actually that would be changing focus, not zooming. Just as an example, when you zoom you see less in your image, while changing focus does not change the width/height of your image but as you correctly say allows you to look at something more specifically.

I always wondered what the difference in strength is between coarse and fine thread. Sounds like the answer is pretty simple, even though there are "entire fields of study" on threads.

We already use the metric system. We also use imperial. Why limit yourself when one system has glaring shortcomings. For instance, have you noticed the metric system doesn't make lathe work any easier? Because imperial system has more divisibles than metric. Circles are 360°, imperial devides easily with circles. Not so much with metic. When I cut metric threads I'm changing more gears than cutting. Imperial threads are so much easier because they divide so much easier by 360.
