Finishing The Cylinders! - Pennsylvania A3 Switcher, Part 46

[@Blondihacks]

Hey everyone! I don’t usually release two locomotive videos in a row, since I know this project is not everyone’s thing. However, judging from the comments, I inadvertently created a big cliffhanger last week and I don’t want to make everyone wait two weeks to resolve it. I hope you enjoy! Update: Since conspiracy theories are abounding, the drawing says 2021 because that’s the last time I remembered to update my Fusion template.

[@MikeMichaels-f5i]

ANY video that You release are consumed with great pleasure and enthusiasm. Just LOVE Your channel, videos, work, commentary, EVERYTHING ! THANK You QUINN. 👏👍

[@mikewalsh7337]

Every episode is a cliffhanger until the project is done :) Great work - I have built cylinders in similar manner as you did, so I feel your pressure! Keep up the great work!

[@shanebergeron747]

Glad to see you were able to continue with those same parts!

[@willetherington]

What @user… said. Anything you do is awesome. Keep them coming and THANK YOU!!!!!!!

[@joshclark44]

Every video of yours is the best and the locomotive series is actually my favorite! You rock!

[@ke9tv]

"A little bit of antialiasing" - wipes coffee off monitor. Quinn, you're hilarious!

[@Blondihacks]

I’m always pleasantly surprised how well computer science jokes play around here. 😛

[@ParanoidMarvinMk2]

​@@Blondihackspeople who are fascinated by EXACTLY how things work are much more likely than average to A) go into fields like software dev or machining, and B) appreciate the other fields that share that passion. Greetings from Ontario/Quebec! Yes, I split my time, yes, I know that gives the ROC two reasons to hate me. C'est la vie.

[@joselrodriguez5999]

Yes, that was subtle and very clever! :D

[@joshclark44]

​@ParanoidMarvinMk2 you're right about that. I'm a prospective AI engineer and I've been watching machining on KZbin for at least 6 years now just because of the level of detail and precision you guys get around here!

[@berndheiden7630]

⁠@@joshclark44That goes for all professions that have to deliver precision. As a dentist I share that passion for precision that we have to reach freehand with a turbine driven high speed „drill“ (400.000 rpm).

[@RonCovell]

Quinn - Wow, that was some VERY intricate work. I could feel beads of sweat on my forehead, just watching. Congratulations for pulling it off like a champ!

[@GeneKrawczyk]

I love the reference to the video cards. I remember buying the voodoo2 LOL. Great work as usual.

[@mickeybags14]

This is by far my favorite series on KZbin.

[@BrendanRaymondKoroKoro]

Locomotives are very very much 'my thing'. I'm super happy we got 2 vids in a row! This is currently my favourite project on youtube and has been since you started the boiler 😊

[@TandaMadison]

Hmmm, already have stickers and somewhat fond of my pancreas. That steam chest looks fantastic!

In the World of great artists, their medium of choice bends to their will and in their hands becomes a thing of beauty. Michealangelo - Canvas, paint and Stone. Da Vinci - Canvas, paint and timber. Quinn Dunki - Brass, Aluminium and Steel.

[@MikeMichaels-f5i]

Well said ! 👍 Quinn is in a league of her own. A perfectionist and the epitome of a Skilled Craftsman. 👏

[@jimsvideos7201]

Also that low-polygon finish on the castings looks sharp, not gonna lie.

[@Repairman87]

Wow! That was some unexpected ATI shade! We used voodoo's in our atm's a million years ago, but they were solid for being on 24x7. Great video as always. One of the few I look forward too.

[@Kim-kl5jh]

Beautiful work on the cylinders, Quinn! These are challenging parts for sure. And it looks like you dealt with that 0.020" issue masterfully! Nicely done!

[@scottgifford467]

When you said it was going to be a shaping process, I immediately thought of some kind of liliputian Abom shaping these small parts!

[@larryriehle166]

As a model railroader I'm loving this series. I also enjoy your narrative and gratuitous sarcasm.

[@wallyschmidt77]

I'm not a machinist or a modeler. I'm just here for the gratuitous sarcasm!

[@mrsockyman]

These operations are terrifying!! The anxiety just watching probably doesnt hold a candle to what was felt at the machine 😂

[@SethKotta]

Every shop needs a small cabinet labeled "in case of scrapped 30+ hour part" with a bottle of rye whiskey inside.

[@orbatos]

Don't forget to label it as glycol poisoning antidote.

[@MikeMichaels-f5i]

😂

[@davebenedum9253]

I have never done machine work, I have never used a mill and have never used a metal lathe. But I also never miss one of your episodes. Thank you for the knowledge and entertainment.

[@AshlynnCairns]

No lie, this is probably the most entertaining thing I’ve watched.

[@Froobyone]

There's two of them, so Voodoo 2s in SLI mode. Love it.

[@halo6six6]

Those might be two of the finest examples of machining I’ve ever seen done by hand! Spectacular work, as always! I was here for the cliffhanger.

[@machinistrrt]

I like that rotary tilting table- wish I had one. Here's a tip: Assuming there's room under the head, use a repurposed windowshade roller to hold your waycover, place a plain roller at the base of the column,run the waycover under it and to the saddle. If you've removed the ratchet, it'll keep tension on the waycover as things move. Remember, in this economy, Poverty is the mother of invention!

[@glenn_r_frank_author]

I don't know how that operation would be don't without a tilting table like that. It would be a real pain to get it angled and clamped just right!

[@EngineerRaisedInKingston]

What an incredible achievement, Quinn. Genuinely edge of the seat moments when you were drilling the steam ports. I remember doing it on my simple 10V engine casting and how nervewrecking it was waiting for the drill to break through. Can't imagine it on this sort of scale. Well done!

[@peralmstrom]

Voodoo 2, now there's a blast from the past. Lovely work, Quinn - thanks for sharing it with us!

[@jamiemacdonald436]

The Voodoo 2 reference was 🤌

[@Blondihacks]

I wrote my share of Glide code back in the day 😬 It was a wild time

[@azyfloof]

@@Blondihacks I remember writing gouraud shading routines in QBasic back in that day :D I appreciate that reference!

[@mekagoenlaputahostia]

Oh, yeah, that brought back memories of me playing Half Life and NFS 3 on my late teens 😊

[@Tom-k7m1j]

I’m always here for a locomotive video

[@charleswelch249]

Quinn, your work is definitely very tegous, and everything you have done was more than difficult. I have enjoyed every episode in this build.

[@markmonroe7330]

Excellent presentation. Thank you. The problem solving and adaptation to your shop environment is part of what makes these personal projects fun and interesting - both for you and us. I think Kozo would be pleased with your challenge solving.

[@danstephens9500]

Great work, as always. The photo of the two cylinders side by side looks like some kind of steam punk binoculars.

[@rexmyers991]

I continue to be awed by your ability to create set-ups and Fixturing solutions that are just BRILLIANT.

[@Jim-fe2xz]

Wow! I'll bet you're glad to have those behind you! Actually I thought they looked pretty cool in rough form - almost fluted but not what you were looking for. I've been retired for quite a while but remember times when people would deviate from my drawings. It was always a balance of something I missed vs something that needed to be followed for good reason. One guy would say "drawings are just a suggestion" which may work until it doesn't. With things that fly it's important to know exactly what was built. Anyway beautiful work as always! Glad you decided to save the castings!

[@paulwomack5866]

Loved the video game rendering references on the faceted cylinder...

[@bensonyoutuber7944]

My understanding of how steam locomotives work took a big step up with this video.

[@myfavoriteviewer306]

I'm looking forward to the final project, complete with ray tracing and frame generation upgrades, of course 😂

[@thecanadiantradesman7916]

I gotta say my first encounter with a model steam engine was in my grade 7 shop class and I was in awe of the simplicity of the it but also the intricacies. I had started to make a very simple version of one and like most kids the school year had ended as did the class and motivation. Watching you videos brings me back and I'm once again in awe and love watching you build these models. I wish I had more time to invest into another hobby and start down the rabbit hole of model engineering, I guess when I get a little closer to retirement il find some time. I have the equipment albeit a bit larger than practical, as in way to big but it can still be done. Thanks again for sharing your experience and knowledge. Keep it up and look forward to the next one 👍

[@jimmcwhirter3798]

I now have serious angle-table envy! What a beautiful piece of tooling. And the video card references were great!

[@joselrodriguez5999]

Even for those that are not into little locomotives your videos are a master class in workholding and precision machining. Enjoy every minute!

[@Hyce777]

25 hours into just... itty bitty cylinders. Ugh. I do not like the look of my future! Lol. These are the most complicated bits of the full size locomotives, and I assume it's similar in the small scale. Seems to be a smart solution - always fun to see! As well, not sure if you follow automotive things or if you saw the interview, but James May of Top Gear / Grand Tour fame mentioned you directly, which was very neat to hear as a viewer! :)

[@Blondihacks]

Wait what?! I love May and Top Gear. Where did he mention me?

[@Blondihacks]

Oh I found it! The Donut guys. Wow, unbelievable.

[@Hyce777]

@@Blondihacks Glad you found it; my buddy Leighton told me so I didn't have the video handy. Supremely cool! I'm jealous. :D

[@Antti_Nannimus]

You demonstrated very impressive skills and accomplishment in those steam-chest components, and it seems clear you have reached some kind of elevated Next Level of mastery now!

[@johnapel2856]

Wow. That was incredible. Beautifully done! And I am rather fond of my pancreas, so if I ever get to see this locomotive in person, mum is the word. Thanks, and Meow to Sprocket.

[@petedepledge3359]

I, on the other hand, had a disagreement with my pancreas a while ago and we parted company. 20 thou? About the thickness of a couple of stickers I think, eh Quinn? 😂

[@mikestevens8046]

That was pretty awesome. Thanks for sharing

[@WesleyHarcourtSTEAMandMORE]

In some very old stationary engines they had cast iron covers over the cyliner insulation. The covers had grooves or fluted depressions in them. Kinda looks like that on your culinders where you cleaned them up. I like it 🤓

[@dwightbrown2808]

Those were amazingly intricate. So many do or die operations.

[@danblair5113]

Anti-aliasing! Loved that. Loving this whole series.

[@heighRick]

Amazing effort Quinn, what a watch! Thanks for bringing us along with you on this, helps a lot!

[@jwbrit]

I forget you are/were a computer person until you pull out a comment like the low poly/voodoo callback. That both brought back memories and made me laugh out loud.

[@thedabblingwarlock]

Loving how these are coming along. They're looking good.

[@Al-os2cg]

This took me back to my drawing office days of the, in triplicate carbon copy, Request for Design Deviation or RDD record book, the shop floor would have a moment( we all make mistakes) and the deviation would be carefully noted for the design file. The relevant drawing would be Sepia printed modified by scratching off the line work or just the dimension reference, and the new dimension and feature pencilled back in. 😂. I loved my time as a design draughtsman. Keep up the good work.

[@andrewschnabel3843]

wow you knocked it outta the park again! great job and thanks for the motivation

[@terrykohlman7355]

Keep the loco videos coming! Thanks

[@crichtonbruce4329]

So, so, so, impressive Quinn. I breaks my heart you need to powder coat that beautiful shiny brass, I love the look of brass.

[@michaelohman4980]

My sentiments exactly! They'd contrast beautifully against the heavy black of the side plates, however incorrect it maybe,...

[@jikemenkins7098]

Hell yeah Quin!!! I can remember playing Doom, Quake, and Quake 2 on a hand-me-down PC from my older brother with a VooDoo II

[@garychaiken808]

Great job. Thank you 😊

[@RustyInventions-wz6ir]

Very nice work madam. This engine is looking great. You set very high standards. Thanks

[@iainmcculloch5807]

Beautiful work, and a nice recovery. I'm really looking forward to seeing them run under steam.

[@manythingslefttobuild]

Great video Quinn, the cylinders look amazing.

[@johnpurcell7728]

Voodoo2, ATI, GeForce. Takes me back to the early days of my career. Too bad you couldn’t work in a Creative or Tseng Labs reference too! Excellent work, as always.

[@adamharrisdrums6539]

that was tense! stunning work, well done.

[@volkeresper9519]

Wonderful work, Quinn! Love it

[@JBLewis]

Thought of you on my recent trip to London, where we visited the engine room at Tower Bridge. They still have one of the four steam engines turning very slowly under air power. I understood the engine much better than I otherwise might have after watching your videos the past few years.

[@terrytopliss9506]

My fingernails are down to the knuckle Quinn,very intense. Well done and thank you for the video.👍👍

[@Obiwank-u4v]

Quinn, this is awesome, thanks for your work and skill and (at very few times) the "good enough" attitude. You were commenting on "tolerances" not being marked. Kozo mentions tolerances in the K-27 book, Section 2.1 that he's not really designing for interchangeable parts, rather, good fitting parts doing their job. I think he's used to working to tenths, though. George Thomas says the same thing--"try to hit the dimension, else it gets too hard to keep track."

[@OGTtom]

Great work Quinn , thank you for posting

[@Vormulac1]

Voodoo 2 cards were awesome, I had a pair SLI'd together - what a beast 😊

[@davidtaylor6124]

Fantastic job on those. I messed up the port location on my current project (despite having a DRO and using an edge finder) and had to mill the entire port face out and silver solder a new one in. I didn't notice a difference silver soldering to cast bronze. The only benefit to this was that I now have milled transfer ports for most of the distance.

[@kencarlile1212]

Woo, congratulations! Awesome!

[@felixcosty]

Thanks for the video. This is a part where a 3D print would help. You use the 3D part to do setups for angles.

[@larryschweitzer4904]

That's one very nice tilt table! I tried to find it on line but no luck. Nice job on the cylinders.

[@jrmintz1]

Fascinating! Your patience and meticulousness is beyond belief!

I know what I'd say in person: "You know what, I reckon those cylinders are the slimline version. They look waaaay better than the normal ones, and they're clearly streamlined and lighter. Great choice!"
