Oh thank God, something decent to watch. I was just down some rabbit hole of pan sauces when this came up.

[@dwaynetherock-hardjohnson5676]

Machining is just a pan sauce if you don’t think about it at all and squint your eyes

[@csours]

Now you have some chips to go with that sauce

[@TheDistur]

Don't underestimate a good pan sauce!

[@fernandofert9960]

Machining channels are a entirely self contained rabbit hole.

The reintroduction of the mystery cube is funny every time

[@JamesTM]

Every week, I see your video pop up in my feed at some point and go "Oh yeah! It's Saturday!" Inevitably, I make a point of wrapping up whatever I'm doing and making lunch as an excuse to sit down and watch. It's honestly the highlight of my weekend, no matter which project it is. I don't even have a mill, but your videos never cease to entertain and educate.

[@thesfreader3068]

Heard "Click out of one"' when you were fishing this nylon piece. Welcome to the Lockpicking Machinist !

[@DavidLindes]

hahahaha, I hadn't had that thought, but... now that I have, I can't unthink it. What fun. :)

[@chriscmoor]

This whole process is interesting. Thanks for taking us along. And a small tip for getting little fiddly bits out of little fiddly holes... use a hot glue stick. Just soften one end with a bic style lighter and when it is soft enough, jam it onto the end of the fiddly bit you lost in the fiddly hole. A few seconds to harden and it will pull the fiddly bit right out (or if the hole is threaded like this one, back it out like a screw). This also works magnificently for extracting a broken key from a lock.

[@patgreene6040]

Much as I enjoy your practical machining advice, I LOVE your sense of humor and delivery. I would love to see a collaboration video between you and This Old Tony.

[@keveburd]

Many an avalanche victim might have been saved if only they had carried their brightly colored string trimmer line.

[@DavidLindes]

Yeah, never mind that it's buried inside a part that's mostly black on the outside. 😂

[@StopaskingformynameYouTube]

You could also just have forced the nylon avalanche rescue pin out with air from your compressor, would probably kill a random passerby, but you would atleast find it after!

[@RNMSC]

Keep in mind that the random passer by in this case might just be the shop cat, and good quality shop cats are a royal pain to get to show up once their network starts passing around what happened to the last one.

[@DavidLindes]

@@RNMSC hear hear. Don't kill Sprocket, please! :D

[@Krmpfpks]

Sprocket is not allowed in the machine shop, otherwise the cat might chase the avalanche rescue pin like a laser pointer.

[@jamesgardner2101]

You kept me in suspense right up until the end- I was watching for how that block integrates with the assembly.

[@swittman9123]

It makes so much more sense in context, now!

[@samuraidriver4x4]

That high tech nylon looks a whole lot like weedwacker string.😁 Great video as always.

[@JaenEngineering]

Was thinking the exact same thing but hey, if it works it works.

[@RNMSC]

Yep, I was thinking maybe 2.8 mm nylon filament from 3d Printing, but most of that is not colored, so... Weedwaker line seems likely.

[@paulsotheron710]

There are a few machinists whose work I look forward to watching, you being one of them. Thank you for sharing your work and for the entertainment. 👍

[@russmilton4491]

The bend in the allthread was undoubtedly to accommodate the misalignment of the drilled & threaded hole after it moved during drilling

[@DavidLindes]

hahaha, nice.

[@jimpiatek5063]

You make wonderful videos, I love the “Adult Language Pause” sign

[@BetweenTheBorders]

I love hand riveting. You can make permanent metal to metal connections, attach soft materials to hard, make rotating and even sliding joints, and there's no better practice to improve your hammer control. Hitting a nail? Easy. Hitting the edge of a rivet with a ball-peen to roll the edge over without damaging the plate below? That takes practice. Plus if you have a domed finished end, it has some beautiful facets.

[@Tyrope]

Thank you for adding that unattached piece to the table at 22:48. I couldn't tell what the new part was supposed to do without it but now it all makes sense.

[@HlGHPlNG]

I'm really looking forward to finding out what that funky cube thing is. (no spoilers if you already know. I am purposely not looking it up so I can learn it from quinn when she reveals it)

[@iamarawn]

On vacation, walking in a forest. Had to check and there's a new video! Nice

[@markwarner5554]

I like how mysterious this machine is. The more of it I see, the less confident I am in my guesses as to how it works.

[@Gellis12]

The further along this series gets, the more confused I get about that first piece you made. Can't want to see how it all works at the end!

[@owengrossman1414]

When I’m straightening something like the lead screw stock I put an indicator on the bottom side. This lets you determine the farthest point you can push it to and still have it return to the original position. Then any pushing beyond that point will be permanent deformation. If you’ve measured how much bend was in the stock originally you can pretty much go by the indicator to remove the bend.

[@crichtonbruce4329]

As someone who has done a lot of freehand sharpening, or with makeshift jigs I can't wait to see what all this actually does. If even Quinn is not yet sure, well, it's bound to be interesting.

[@Radiotexas]

Quinn- Not are you one of the best machinists on KZbin your photography and editing skills are top notch. For over 140 years my family have been professional photographers in both still and motion pictures so I do know something about the craft! Keep it up!

[@steveman1982]

Seeing "widia" on the end mill boxes reminded me of a company in the town I grew up in: "Widia Nederland". For a while I vacuumed the factory floor there once a week as an after school job. Quite tricky to maneuver an industrial Nilfisk vacuum around all those brittle pre-heattreated workpieces on carts. That place was incredibly dusty, it cannot have been healthy to work there. The Dutch site of that company has been closed for years now. Fun fact: widia comes from the German "Wie Diamant" which translates to "like diamond".

[@timvarner1]

Not sure how you make this so entertaining every week but by god I look forward to my Blondiehacks every Saturday. May sound like I have a dull life but nothing is farther than the truth. I just love the pure joy of making.

[@johnapel2856]

Very nice! And I did not realize that dropping tiny pieces into the chip tray was obligatory. I assumed it was just tradition. And we all know what assuming means. Right? Thanks, and Meow to Sprocket.

[@RNMSC]

Always remember, if you as a viewer need some tips on how to make the brass knobs for the adjustment mechanism, Chris over at ClickSpring has a master class of videos on how it's done on a Jeweler's grade mini-lathe. You may have to compensate for discrepancies with your lath. I will remind you to go through the videos for tips on setting up cutting tools for cutting brass, as it has some odd cutting characteristics. You may need this tool sharpener to get the cutting and relief surfaces on your cutter's correct. :-)

[@OGTtom]

Always enjoy Saturdays and i get to watch your video , thank you Quinn .

[@temporalillusion]

Riveting is riveting.

[@TheDistur]

Datum? I hardly know um! Been enjoying this project!

[@RNMSC]

The thing is, if you don't datum, you're never going to know um. Some of them are rather skittish.

[@giantpune]

21:20: I've done that more times than I'd like to admit. My go-to is the air compressor, or a shop-vac with the hose on the "air out" port. An aerosol can with a straw, like WD-40. I've even resorted to a grease gun once or twice. For larger holes, you can tear up a piece of bread to cram in. I guess bread is pliable to fill the void, but doesn't compress well. I picked that one up from grandpa removing pilot bearings.

[@mrjacob8836]

Aerospace machinist here, calling "datum" surfaces as reference surfaces is totally normal in my mind. G, D&T is one thing then there's what we actually do in the shop. :)

[@Halinspark]

My shop is lucky when I go a day without calling my lathe "the thing-rounder".

[@kensherwin4544]

@@Halinspark My 'thing-rounder' is actually set of them, with sizes on the handles such as 8", 12", and 18" with a label that says 'Crescent'. Each one has a thumbwheel on the side that controls just how round you want things to be. They also make convenient hammers.

[@mrjacob8836]

@@Halinspark lol

[@manythingslefttobuild]

Great video Quinn, looking forward to seeing the sharpener in action. At 21:36 if you have compressed air or other gasses you could have unscrewed the depth adjustment screw past the cross hole and blown it out, with or with out a custom fitting, before resorting to fire.

[@carlnelson6601]

Quinn, one thing I think your more inexperienced viewers should learn is that the big problems with derived dimensions is that is that if they weren't just a reference they would create a "double dimension" (an "over constraint" in modern parlence). It is important that any size or feature location only be specified once, in particular because it creates tolerances that aren't compatible if you start to add them up. For example, in your part if that reference were an actual dimension the tolerancess to the left edge and to the right edge from the feature would make also speciifying the total width unacceptable. Being an old guy, I taught this to a lot of young engineers and drafters over the years.

[@ChrisHiblerPinball]

Squirkled! Nice. I shall adopt this term in lieu of the less elegant “honkered up”. :)

[@davidhaywood8029]

Fun fact: a squircle is actually a real thing in physics/optics (square + circle)!

[@ChrisHiblerPinball]

@@davidhaywood8029 lol. Glad I learned that today. Thank you. My mind went to something involving squirrels. Doh!

[@jeremylastname873]

Compressed air would get the safety orange plug out, and you could see it from across the room when it came out.

[@joehotpaint1]

Hi Quinn, just wanted to say I think your videos, particularly the tutorial stuff (such as the lathe and milling for beginners) are extremely helpful. Im new to all this but not new to ‘making’ stuff, im a fine artist (painting) who recently decided I want to make physical objects - such as automata, alien weapons and basically all manner of things. Im a big Thomas Kuntz admirer and he has been my main ‘eye opner’ for what i think my true calling is. But before i can make reliable moving parts out of metal i need to know how to do it and your clarity and amazing communication abilities have really helped me. In terms of the machinery i have its all hobby level ‘robustnous’ - i have mainly Proxxon stuff including their largest lathe (the PD400) and their ff230 milling machine. The lathe only has a 500w motor and the milling machine even less so i recently bought a relatively powerful mill - basically a european version of your Precision Matthews, but one size down. Its about 1HP and ive trammed it in (per your instructions!) and it has an R8 spindle. Anyway, im blathering on, thanks again, Keith Rucker could learn a thing or teo from you! Alll the best from the UK, Joe

[@csours]

Its funny how "Reference" means either "Really Important" or "Throwaway"

[@joewhitney4097]

Appears to be a fun little project. Enjoying the show. Just a thought on removing the nylon had the wire not worked, thread in one of the holes and use compressed air to push it out. 😉 Thanks for sharing.

[@PatriciaSawyer-ot4us]

Hi Quinn. Great Vids. Just wondered if anyone out there, who's just got a simple cheap lathe and no milling machine with no DRO etc, knows the old school way of using a face plate, verticle slide, "keats" angle plate etc, to machine bores or other features etc...Would be interested to hear your comments! Cheers.

Another great video. I am coming late to the video this week. I am building mine from the drawings only so thanks for the 'props'. I actually riveted the Feed Slide Stop to the Feed Slide. I agree that riveting is a strong an attractive way of joining parts. Guess I like doing things the hard way 'cos I turned the setting screws in a single piece creating knurled thumbscrews on the ends.

[@paulwomack5866]

Perhaps a tiny drill bit into the end of the nylon locking slug to make a hole, follow by a small bolt might have pulled it out? Like a 2 stage easy out, but hopefully better. But your solution worked, so it's academic.

[@pucharen]

7/16 freedom units shoud be very close to 11mm same goes for 5/8 =16mm 3/4=19 and 15/16=24mm

[@monkey_breath]

datums is actually correct in that case, since it is referring to multiple sets of data with different reference points. my father would have a small speech ready for that, and stuff like the distinction between accuracy and precision. and even if both him and therefor i am wrong about it, thanks for at least making me think of now fond memories of him.

3:56 And the "Yahtzee" has officially evolved into a recognized verb in machining! (To) Yahtzee - v. To cause the instance of separation between a machined component, and the rough stock material from which it was made. See Also : machinist’s lathe.

[@kaiheetjans9956]

2:15 In Germany we call them "Hilfsmaß" so it could be called an "aid" measurement in English. It is just an aid, so you know, you are in the ballpark.

[@DavidLindes]

Ooh, good to know. Just looked that up on Leo (a German-English translation dictionary, for anyone reading this who doesn't already know that), and it gives the translation "auxiliary dimension [TECH.]", which also seems a useful way to refer to it.

I’m afraid I’m not familiar with your use of the highly technical term “squickle.” 😂 Your videos are great as much for the humor as the information!

I would have removed the nylon piece with compressed air. Just hold finger on the other end of the threaded hole and quick psst and the nylon should fly across the workshop in no time.

[@StevenStyczinski-sy8cj]

Fly across the shop and find a new corner you didn’t know about.

[@Halinspark]

You don't even need a finger, just don't unthread the rod all the way.

[@VilleLiski]

@@Halinspark I considered the case that it would be easier to fit the nozzle to the hole that is not next to the plate. But finger could still fit and seal the hole sufficiently near the plate side.

[@robertburns2415]

Nicely done How are you enjoying your new home?

[@joedyhicks9415]

If you have access to air pressure- getting that piece of nylon out of that hole would have been a snap, downside would be that it would enter into low earth orbit and you would have to make another one anyway.

Could you have removed the bit of orange plastic with compressed air? At risk of sending across the shop like a cork.

[@nickrivera2391]

Off topic from this video, but is there any chance of getting a video (or are there resources available?) on how to choose the best type of steel for a project? I’ve watched the materials video, and lots of other peoples’ similar materials videos, which are great for learning about all of the common “flavors” available, but I haven’t found too much available for the hobbyist that goes into detail on how to choose the best alloy for the job, particularly with low, medium, and high carbon steels, or tool steel. Kind of a “Materials 102” class.

[@metamorphiczeolite]

Not a "Materials 102", but some background reading could include the Materials section at McMaster Carr. Informative.

[@davidcahan]

U may have mentioned this in previous videos but I'm curious, about how long (in hours) does it take you to make each video? (and by "make" I mean to the point that it's ready to upload to KZbin)

[@millwrightrick1]

Back in the 80s, learning g blueprin reading, I never came across a dimension in brackets. Live and learn.

[@RNMSC]

I think the most likely place that I'd expect to see them in production drawings would be on surfaces that are the hypotenuse of two specified surfaces. Possibly most useful for jobs where the angles and the right angle surfaces are critical, as is the surface of the job adjustment angle, but the actual dimension of that surface is going to be different across the entire surface, and since it's there to be a means of adjusting the action of the ways, it's more important that it be nominally a dimension. Additionally it's likely to be a surface that will experience wear, and knowing what it is expected to be nominally, you can make decisions regarding whether the well used jib is still acceptable. (Note, I'm not sure if it's Jib, or Gib in this case. I tend to think of a Jib more as a type of sail on sailboats, but it's entirely possible that the component got it's name from that sail as a result of the shape or shapes involved. I think I've also seen it spelled as a Gib in some places, yet pronounced as a Jib, similarly to how some people pronounce GIF files. Regardless of which is the correct pronunciation according to the file format creator. Or for that matter how does one pronounce 1.21 Gigawatts...)

[@Halinspark]

​@@RNMSCIt's also good for parts like this one where the width is important, the centerline off the fixed jaw is important, and the other dimension just has to be whatever it is to account for tolerance.

[@BeekersSqueakers]

If reference dimensions are non-critical, do they really need to be in the drawing? I've always just left those types of dimensions out. The only time I can think where I might've used one was for rounding corner radii. The corner just needed to be rounded so that it wasn't sharp. It didn't matter what the actual radius was. I usually just add a note saying to round but radius is non-critical. Are there other situations where they might be useful?

[@jonduke4472]

On the too long nylon.. Do we think fluid impulse would have worked to coax it out? Can't be certian but it didn't seem wedged to hard just inaccessible. If anyone tries it just remember to point the exit hole away from face.

[@kencarlile1212]

OK, that change from reference not meaning reference but the opposite of reference is really baking my noodle.

Coolness. 🙂

[@mrtnsnp]

Drum roll please: rivets are a riveting subject.

[@beartastic-ftw]

I think fusion 360 calls it a driven dimension, not a derived? (Or, did, back before autodesk killed the free version at least)

[@WHJeffB]

Same with Solid Works... SW will prompt you to choose whether a redundant dimension is the driven dimension, or if it's the primary one (terminology may not be correct, I'd have to open SW and force the incidence to get the correct verbiage).

[@HlGHPlNG]

Killed the free version? I still use it almost daily. When they changed a while back from "free for students" to "free for hobbyists" they made it so you can only have 10 editable projects at a time, but that has been a nonissue for me. I just toggle the projects I'm not currently working on to 'read only'.

[@beartastic-ftw]

@@HlGHPlNG call back after trying CAM or other advanced features.

[@HlGHPlNG]

@@beartastic-ftw Yes, I suppose they 'killed it' for people trying run CAM or some other advanced things, but for someone that is using it for modelling for 3D printing, and circuit design, it's still got everything I need. ...and having tried some of the other free options for modeling, I think Fusion is still the hands down winner (for the things I need it for)
