I am now convinced the internet has everything anyone needs to become very competent in any trade, for free. For me, the one weakness has always been knowing the types of tools and techniques that exist. That's the main advantage of working with an experienced trade person - they will teach you the most efficient means in every situation, whether or not you know to ask for it. But now with channels like David's, this weakness shrinks drastically. You'll commonly hear me say "I didn't know that existed!" or "you can use it like THAT?" while watching your videos. You're turning hobbyists into engineers, it's incredible.
This is amazing. Thank you. 10 yrs back I was making 30,000 reliable, clean, safe engines per month and never got one thank-you. Fat salary, no thanks. With comments like yours I’ll never go back. Just need to know it makes a difference. that’s all. And If my colleagues at toyota only knew the other side of life…
my god, your channel is a reminder of that thing where your self imagined level of understanding in a subject matter is inversely proportional to how much you actually know about it, I hope I worded that clearly, I cant think of the academic term for the phenomenon. I want to call it Freddy Kruger effect, which is for sure not the name of it. but yeah, Im like, "pfff, this guy ..... what can I possibly learn from this smarty pants... oh my god, my calipers can do that?!"
I love your videos David, they're honestly a guiding light for young professionals. I was wondering if you could do a video on another highly important but underlooked practical toolset, writing utensils. I would really love to hear your opinions and experience here.
A nice video. I'm quite an old hand (certainly old) but learned a new trick, anyway. Young engineers absolutely need to spend time with old machinists - designing stuff that can actually be manufactured (without spending a fortune) is an art that absolutely needs sensitivity that only experienced machinists can teach you.
I know you said you won't be going into the type of materials, but depending on the material determines the optimal rake angle of the cutting implement. It's a weird concept that a "duller" drill bit can cut better into materials like HDPE and brittle metals. I am always learning from your videos and I love how you have examples showing the technique.
If that washer was secured on top of a piece of wood then clamped down closer to the hole being drilled, then it would have less vibrations when being drilled and easier also. Good informative video And great content on your chanel.
Hehe, bonus points for having the air lines secured to the tracks! I didn't mean to give you too much greif about it last time to make you do something about it.
keyword: HEXRACK upload: grabcad.com/library/hexrack-1 I finally uploaded these. You're the 5th person to ask about them and I finally cleaned up the files. In the future, all my models go in my grabCAD profile. grabcad.com/david.m-50
Learned a couple of things and drooled over your tool organization. I thought you might cover more on the tendency of bits to grab at the end as they plunge through and the need to secure the work or your hand to avoid getting wrenched. And the difference between a general purpose twist drill and a brad bit. And that reamers exist.
I never found an affordable reamer, do you have a favorite to recommend? Also it’s time to google brad bit… thanks! Oh wow i was about to dive into tip geometry - yes this belongs on the “not covered yet” PDF
May i ask: what is one aspect of your favorite cutting lubricant that you don’t get with the next best selection? i recently switched from expensive cutting fluids to 5-W30 because i can’t detect the difference in results.
I agree for most use cases 5w-30 is an excellent lubricant. I work with space flight hardware and silicone contamination is a concern. Another benefit to it is that it’s a paste and if you’re drilling something above you, you can place it without having it drip away. It also makes clean up a lot easier. I will admit I’m biased towards it because it saved me from match drilling titanium with alcohol as my only lubricant.
A punch or a drill and a file. Filing is surprisingly efficient at removing material and slow enough to be decently precise. But with out knowing thickness it's difficult to give you the best answer
In your followup video, *please* ask folks to *absolutely* *NOT* use *quality* (i.e., expen$ive) calipers like Starrett, Mitutoyo, etc., calipers for scribing lines on workpieces -- use an "el cheapo" brand instead for that. Your Campus Machinist will probably slap you up-side the head if you try to damage/use his/her quality calipers like that! Also, a sharp scriber should be used with a scale, combination square, etc., for layouts that need to be relatively precise. Noga, and most likely similar tool makers, offers a set of deburring tools like the two that you shared, plus one that allows you to reach through a hole to deburr the backside of the hole, along with a few other deburring tools.
This is hands down the best video named how to make a hole I've ever watched

I always click on your videos thinking what can I possibly learn. Only to gain tons of useful advice for my builds. Great work
Likewise - keep it up
These videos are so great. So much info, presented visually and concisely.
Came across this video while brainrotting on YT shorts. Thank you for your brilliant work

love these series where you spend an hour going through all the options
Thank you so much for the proper demonstration on how to use a center punch! 😂 It drives me insane when I see more then one squeeze ughhh
Very informative videos please don't stop making them

you're a gem please don't stop making those informative videos.
new subscriber here. Really love how you organize your tools.
Great video mate, thanks for taking the time to put it together for us!
So glad it’s helpful! Yeah this one took much longer than I hoped 😅

feels good when folks pay close enough attention to notice those details. cheers!🥂
0:48 - what are those wall mounted green holders? I need those in my garage😂😂😂

Im learning so much from your videos! Thank you and keep going!
45 minutes on making a hole never sounded so exiting !! 😄
I'm not exiting at all. Staying right here to watch the video
@@brutongaster8184 Ooops 🙈
Exciting of course ! 🤭

Boelube is my fav lubricant for drilling + it’s clean room safe

Just amazing !! Thank you
I stopped using those Calcium Chloride desiccant things (seen in the tool drawers) because of worries about corrosion. Still not sure if I overreacted
PHILLIP!! Teach us your chemistry (i’ll point him here and get help)
4:36 center punch, looks like a Starret 18C (5"). Could be the ligher 18A version. About $70 on McMaster.
i think mine is 18A, i ordered it from a recommendation on a comment and it was only $30 on amazon :)
Weird, I'm watching this again (showing my wife) and she saw that I left a comment. Which reminds me: I need to get that center punch still.
Lots of great tips
Awesome vid, thank you!
Great video. I too like to build robot stuff and this is great knowledge
Thank you.
Fastest I've clicked on a video in long time
Such a comprehensive video! Thank you!
Where do you get that dispenser at 37:03 ?
the deceased grandpa of a friend 😅. i don’t even know the name of it.
Hey, thank you!
how do you make a square hole in steel with simple tools?
A punch or a drill and a file. Filing is surprisingly efficient at removing material and slow enough to be decently precise. But with out knowing thickness it's difficult to give you the best answer
@@jumpinjaxs 3-4 mm, thank you for your answer! is there any other ways?
what’s your best option so far and what is the shortcoming? I Can try to offer an answer from there.
th-cam.com/users/shorts0rKAYXkUngA?si=_KsvmcgjsJ5oCtLO
I second the filing comment. May need a triangle file and a good steady workbench mounted vise to hold the workpeice in a comfortable secure way
Started the video thinking I would stop before 5min but couldn't stop till the end.
This is what I need to know
I usually just use my weiner but these are some interesting ideas as well
24:58 in business 😆
lol the business driver/drill
First time I've ever been the first viewer.
Am i supposed to watch the hole thing
i was waiting for glass/ceramic hole making, but nada
i thought about that each day i filmed. what is the last project for which you drilled ceramic? mine was for a household decoration.
25:40 You need a who and a what? Okay I'm done. 🤐
😅

Engineers engineer.
