Building Railroad Car Suspension - Pennsylvania A3 Switcher, Part 17

[@jimsvideos7201]

Is it a coincidence that a gondola car at this scale would conveniently accommodate Sprocket? 🤔🥰

[@OutbackCatgirl]

get that cat an engineer's cap and bandanna

[@johnapel2856]

It always surprises me, in a good way, when I see all the various parts become something. I seem to go from "Uhh, do what..." to "Aha! So THAT'S how it works." Beautifully done as usual. Thanks, and Meow to Sprocket.

[@BeenThrDunThat]

I read your comment first then watched the video and I was like "aha" that's why you said that.

[@BeeGeeTheImp]

Whenever I drop a small part on the floor I always look for it in the last place. Parts tend to be found in the last place you look for them. I like being efficient that way.

[@steveman1982]

I keep searching just a bit longer after finding something. Just to mess up that saying.

[@ChrisHiblerPinball]

I have a couple of really bright lights that shine under my bench. Seeing the part that is trying to escape into the 9th dimension is much easier now.

[@nigelleyland166]

I often drop things deliberately to see what else I find while looking for it!

[@emmajacobs5575]

There was a thing in Tom Sawyer where Tom had lost a marble, so he took another marble and threw it after the first, saying ,”Brother, go find your brother” It only took three attempts doing this before he found the first marble. Of course, if it’s a rare or unique part you’ve dropped, you’ll need to make another one to throw after it …

[@AnthonyHandcock]

I was over fifty before I got the whole '...last place you look' thing. I can be very slow on the uptake sometimes 😀

[@DustyFixes]

I found your little screw! It was in my sock drawer. However, now one of my socks is missing.

[@seldendaniel8819]

I find that placing a flashlight on the floor with the beam parallel to the floor is a great way to see little parts. Sweep it back and forth and they will cast long shadows. Your work is inspirational!

[@Blondihacks]

Good tip!

[@jdos2]

Awesome work as always, Quinn- thank you! I was less worried about druids than rock stars (who's amps go up to eleven).

[@paulkinzer7661]

Watching the tapered milling come to its hoped for sharp peak was nerve-wracking until the moment of completion, which was very satisfying to watch.

[@cuptain85]

Closing in on 200k subs. Feed that algorithm folks!

[@Atomsk102]

The lower crossmember, below the bolster, is called the "Spring Plank". This Old Tony, in his video on making springs, said, "Springs come in all possible lengths and diameters, except the one you actually need".

[@me3333]

Watching you drop that screw reinforces my theory that Narnia exists in every shop no matter how clean it is. 😁

[@capnskustomworks]

We Tiny Druids shall remain!!! Hahaha! Those turned out so neat, seeing the springs go in and it becoming a whole assembly is very satisfying!

[@GunFunZS]

Had a spinal tap vibe.

[@chrisd4987]

Timely as I visited Stonehenge for the first time just last weekend

[@joshuawalker7054]

That's a cool die-filer. Looks well built!

[@davidmelton7268]

About 40 years ago, my first real job was as a service technician at a TV repair shop. I worked with a gentleman who was probably about the same age that I am now. One day, I dropped a screw from the piece of gear I was working on. He gave me the great advice of watching to see where it lands (or at least which way it bounces) before starting to bend over to pick it up. To this day, every time I drop something in the shop, I say "Thanks Bud!" as I watch it to come to rest or go scurrying under a cabinet. Somehow, there is still an amazing assortment of nuts, screws, e-clips, etc. under any piece of equipment I move! As always, great video!!

[@terminalpsychosis8022]

Looking absolutely beautiful. As a big RC car hobbyist, suspensions are notoriously challenging to get right. So many factors from design, to materials, to actual production methods... I suppose getting a scale size boiler to actually hold steam is harder, but these parts MOVE constantly, and that's very cool just in itself. Really looking forward to seeing them gorgeous wheels fully sprung. And go mohawk duckie go! ;-)

[@danielmclellan7762]

I must admit that I cheer every time she tappy-tap-taps something into place!

[@mrimmortal1579]

When searching for a part that has fallen onto the floor, turn on a bright flashlight and place it on the floor. Then sweep the flashlight around and look closer at anything that casts a long shadow. It might seem counterintuitive, but it’s easier to see a long shadow when using the flashlight at a lower angle than it is to see a small part using the flashlight from a higher angle.

[@davidtaylor6124]

Your floor must be a lot tidier than mine.

[@richtes]

@@davidtaylor6124He’s saying “You slobs need to clean up” in a useful way

[@kindabluejazz]

I always just walk around barefoot until I scream - works every time, eventually.

[@me3333]

When I am looking for a dropped something in my shop, I always start at the farthest point from where I dropped it because when/if I do find it it's never in a place that makes sense. Oh and sometimes adult language helps

[@mrimmortal1579]

@@me3333 absolutely, the adult language is a must! It’s how the lost part knows you’re not just playing hide-n-seek. Without it, I can never find anything!

[@spdy3926]

I am addicted to these very informative videos. Your style, and incredibly articulate use of the English language leaves me in a very happy place. The descriptions of the work to be done, how, and why you chose the method is so unique on your channel. It is complete. 😯🥰

[@billofalltrades2633]

I love your fire bricks, I thought I was the only one to have broken fire bricks. I got mine for free so I don't complain! Great job it's looking amazing so far!

[@recklessroges]

Oh look! A nice mug. Perfect for drinking "thinking juice" while looking at a silver play button. ;-) [I appreciate the set dressing, even if I'm here to enjoy the chips & chat.]

[@georgehollowell9295]

Nice job! I had to translate your descriptions though. All my old 1880's literature refers to the 'columns' as pedestals and the 'bottom bolster' is the spring plank.

[@belatoth3763]

Dropped things act like small animals trying to hide. Specially because rolling parts lose their energy by hitting a vertical surface they look like they are trying to find shelter. The harder and smaller is the thing the longer the distance it can take.

[@BetweenTheBorders]

I think you made the right choice posting the spring video first. I think it was more interesting to see their construction in a vacuum rather than be primed to their final use. It's a minor thing, but I think this was optimal.

[@redrockroger]

Saw you testing the temperature of the newly soldered assembly with the front of your hand. I was taught in blacksmithing class to always test for heat with the back of your hand. That way, if you make an error in judgement and burn yourself, a burn on the back of your hand is much less in the way of the use of your hand than one on the front.

[@Blondihacks]

Good tip! 😄

[@TinSandwichUK]

Good seeing one project (the filer) put to good use in another.

[@wayngoodman3099]

LOVE the comment at 8:34 about Tiny Druids! They really ARE nearly impossible to get rid of!!

[@victorparadise5863]

Hi I'm Victor, I make landing gear for wooden models. And I really like watching your stuff I'm learning new techniques. Thank s ❤

[@AmateurRedneckWorkshop]

Well done I am sure that will be a smoth riding train. Thanks for the video keep on keeping on.

[@rolandjohansson7428]

I used to work as a railroad mechanic. It's fascinating to see these objects scaled down to some tenth or fifteenth of real size.

[@donaldsutherland244]

A Stonehenge reference? -and the proper way to find any fallen metal bit, is to walk around bare-foot! Thank you again for these videos, you are a gifted teacher, with a natural talent for communication!

[@vrdrew63]

I was holding my "Locomotive Breath" throughout all of your machining operations....... Just to let you know, there is something incredibly satisfying and enjoyable about one of Quinn's videos. Truth be told, I only understood about 20% (±) of what was going on here. I understand the importance of precision when it comes to pressure vessels and internal and external combustion engines. But suspensions? Uhhhhh...... Love the videos. This channel is a source of great joy and fascination in my life. Thank you.

[@rencleavus5213]

In the "shuffling madness"?

[@oldfarthacks]

When doing a job like this, precision is what keeps you and the project on track. Otherwise things tend to fly off the rails.

[@FrenziedFruitcake]

For measuring chamfers I like to use a scale loupe, its basucially a pocket shadowgraph. Get one with built in LEDs if you are interested

[@UnacceptableViews]

I wish I was half as clever as you. amazing work great job!

[@heighRick]

Thanks Quinn, helps a lot! ...appreciating the duckie for scale

[@vincejamison8078]

I've been riveted to this series. Started binge watching it since the wheel bearing episode. 😂 Keep up the great work.

[@douglasharley2440]

can't wait to see sprocket and swarfy the duck riding around in this *awesome* train you are building!

[@willclark491]

Nicely done as usual Quinn! WTB moar Sprocket though...

[@firebird8600]

Yay!! It's Blondihacks time!!!

[@evanbarnes9984]

Once druids show up, you're bound to have Nac Mac Feegle following shortly thereafter, and then you really have a problem! Good thing you got those arches laid back down quickly, otherwise you'd be stuck leaving out bowls of whiskey and engaging in the foldin' of the arms and the tappin' of the feets. (Really hoping there's another Discworld lover here!)

[@2drx4]

Top notch video and work, as is the standard for this channel. 👍

[@comradesoupbeans4437]

Really appreciate the wide shots in the recent episodes, really helps give an accurate sense of scale missing from a lot of machining videos which often feel like they're on a massive mill/lathe even if they aren't. Helps remind that smaller tooling is still plenty capable.

[@greg4367]

Greetings from San Francisco. Quinn, every Saturday I look forward to your post. It inspires me to get on with my own projects and to try to match your level of skill and competence. Well done... as always.

[@dirtdart81]

As a tiny druid, thank you for showing these manufacturing skills!

[@finnna8352]

"Little Druids" I like your sense of humor.

[@steveboylan526]

Thank you for showing the bolsters. I feel better now! Now back to the cellar and my truck columns ...

[@ChrisHiblerPinball]

Pretty darned cool. It's nice to see it shaping up. The engineers from "days of yore" were pretty smart!

[@StanErvin-yo9vl]

High Quinn. Very interesting wormhole I seem to have fallen into concerning your ongoing build.. Thank you!

[@Peter-od7op]

I love how you teach. My son and I have been follow you and he has learned alot. I would like to donate to you.

[@Blondihacks]

That’s terrific! I have various donation options on my website at Blondihacks.com on the right hand side.

[@iain3411]

Very simple truck arrangement that works very well. Will look very nice when painted.

[@mrrberger]

7:07 test heat with the back of your hand. Spent years in a hot forge and was taught from day one to test using the back of your hand. It avoids involuntary grab at a heat shock, you naturally curl your hand away. You will be left with your sense of touch if you muck up as well.

[@miketripletfab4098]

I am really enjoying following this build series I live a quarter of a mile away from where these were built back in the day!

[@bernieshort6311]

It’s very interesting watching you make these parts and educational your explanation of how it all works. Nice one Quinn.

[@mattl3729]

Tiny Druids LOL You'd need tiny Romans to clear those out and then they'll just colonize everything- that's the real problem.

[@csmcstrsshd]

Oh Quinn, that mockup assembly at the end is so satisfying! Excellent work, and lovely to see a plan coming together.

[@joewhitney4097]

Wow, a lot of intricate parts for this project. Fun to watch your build on this. Thanks for sharing.

[@curtdunlap6818]

Quinn, you really rock it!

[@aknott11]

I'd literally just thought "ooh, Brasshenge" when you mentioned the tiny druids.

[@Wyllie38]

We did some model piece of a stone crusher for work the other month. Doing M2.5 hole on a machine that’s 4.5x1.5x1.5 meters is always fun. 6000rpm is definitely not ideal rippems

[@clivelee4279]

Excellent work , proper production engineering , a tip for squaring the end of stock , use the lathe , grip it in the three jaw ( obviously it needs to fit through the bore of the spindle ) the machining marks are not concentric but it’s square .

[@mperry9025]

Thanks Quinn

[@voodoochild1954]

Quinn, that was an awesome bit of milling! Beautiful job.

[@Kim-kl5jh]

Beautiful work on the columns and bolsters, Quinn. Those parts all look so beautiful in brass!

[@LewHarriman]

Always such fun asides in the middle of such fine, fine and very specific advice. (Sure glad you didn't have to pause to eject Druids... I'll bet that would have been a difficult task.😏)

[@jamesnorlin1273]

In aerospace machining, we’d pretty much always give either the diameter of the finished countersink (minor diameter if on a contoured surface). It might be specified by the flushness requirement for the fastener for assemblies. Either way, a micro stop is your friend.

[@624Dudley]

Thanks Quinn 👍

[@UpLateGeek]

Excellent work, as always. Very satisfying seeing the high level of precision going into such unassuming parts. Can't wait to see the rest of the assembly in action!

[@jimsvideos7201]

For the chamfer, try a ball bearing; doing the math in Fusion360 is probably the fast way but given the chamfer angle and ball diameter you should be able to get dialed pretty quickly.

[@petem6291]

Quinn, I like that method of checking the counter sink /dia. of the chamfer with the gauge pin so simple.

[@raymitchell9736]

☕ I like to watch your videos while drinking coffee... The 4 columns and the tiny little druids remark you made was so funny... well, I needed to clean my laptop screen anyway. 💻 I am learning so much from your videos, not just machining, but about railroad engineering and technology. I do firmware engineering (for a living) and there is a degree of precision needed for those things, but what occurred to me is that if I had learned machining first, that it would make me a way better woodworker (as a hobby)... but most interestingly the same can't be said the other way around... well perhaps that's a bit unfair to say for some master woodworkers, so I'll scope it by saying "the way I approach woodworking wouldn't translate to being a good machinist" And secondly, I'd need a lot more space for a shop that I could separate the two. But I'm not going to lie, I am fascinated by what you do and I hope to one day find the time, money, space, and win the lottery. LOL

[@vicmiller7191]

I thought Duckies liked Druits? So you have a way to bring them for a visit, LOL. This was a real nice example for jig setup. The finished product will be nothing but spectacular.

[@tuoppi42]

Have you considered wrapping the the parts while soldering in something sacrificial to protect them from oxidation? Also increases the thermal mass for the parts that aren't being soldered. Not that the result wouldn't be nice, but might save some effort.

[@azlandpilotcar4450]

Tiny druids can be baited and trapped using the sort of mistletoe found on bonsai.

[@bradhayworth2926]

Spinal Tap has a great little tune that will draw the druids out and have them dancing around tiny Stonehenge. Just make sure it doesn't get trampled. 😂
