The excitement builds towards the ultimate choochification. The construction of the boiler is now but a dim memory, now overshadowed by the beauty and intricacy of the fiddly bits.
You are an awesome teacher. I will likely never build a locomotive but the lessons are great. Every time I watch your vid on Sat morning, I immediately go find something to make on the lathe or mill. That probably means I have too many projects but... Thanks!
"Mill yahtzee!"😂 I have to admit, you kinda broke my brain when you compared the mill operation to the lathe... just physically flipping perspective (like you allude to in other videos going WAY back) was cool to see explicitly pointed out. Thanks for taking the extra time to bring us along on this adventure, Ms. Quinn!
I have no idea how long has it been since you first begun working on this project, but by now it's something i look forward too every weekend, great work Quin!
I admire your skills & have watched this project from the start. I’ve really enjoyed seeing the work you’ve done. Looking forward to seeing forward to seeing some chooching asap. 😃👍
The British used Imperial up till the late 90's. They also used some goofy combo of SAE and Metric, As a Mechanic of 35+ years, I can say that the Brits make great tools, but should never be allowed to build automobiles! Great work, Quinn. You are a true inspiration. God Bless. o7
Quin, Ive been following this project almost from the start. It was exciting to see a rolling chassis on rails. Its exciting to see the project start to come to life. Im betting you kinda must know how that Dr felt when he brought FRANKENSTEIN to life. 😂😂😂😂😂😂😂😂😂😂😂😂😂
That fine line between scrap metal and useful part is all too easily crossed by a stray vibration and sharp tool . Love the videos coming along really well- it will be spectacular when all completed
Wonderful job! I am really enjoying this series. Another reason slide valves were replaced with spool valves was lubrication. When steam superheating was introduced, the oils used at that time could not withstand the hotter temperature steam and galling and other problems occurred. Improved oils with high temperature tolerance were developed. Spool valves were also more efficient for steam flow which was important for producing high cylinder horsepower (not needed for an A3). This is going to be a fantastic running model. We are all looking forward to seeing it under steam and running on the track.
As a fellow bespectacled human, I can't recommend prescription safety glasses enough! They aren't cheap (mine were about CA$500 or thereabouts) but the joy of not having to balance two sets of glasses on your nose all the time is SO worth it.
I know you release a video on this project every two weeks. How far ahead do you work? do you have several weeks of it filmed and just cut for length? I get into projects like this and I can resist just going ahead full steam. :D
@@jeremylastname873 I used one at work from Grizzly and it worked ok as well but it didn’t have the worm gear adjustment. Does the one you bought have that feature and if yes, how do I find one?
2:20 Why does adding paper (and therefore thickness) to the one on the right cause the one on the left to be clamped more firmly? That seems counterintuitive. Is there a lever-action going on that I’m not considering?
the movable jaw of the vice can pivot just a tiny bit. the paper adds thickness to intentionally cause this, but is also compressible enough that it will take *exactly* the thickness required to have both pieces clamped in/
As an English model engineer we seem to work in a mixture of metric and imperial just to make things fun all my masheans are British built with imperial dieles drawings can be both and materials seem to be mainly metric all adds to the fun
what species of valve gear will the model have? are we going to see tiny walschaertz valve gear made? is something more like baker that's more popular in models due to pin joints? or even a specialty gear for the heating and scaling issues that admits more/less steam than normal?
I can't help but wonder if there's any transparent material that would survive this sort of steam exposure and pressure variation; so you might use it as a temporary demonstration valve cover. Big problem for me is I don't know how hot your steam is, or how the pressure in the steam chest varies as the valve opens and closes. Borosilicate glass is an obvious candidate, it's very strong, no idea how you'd shape it. The glass transition temperature of polycarbonate (lexan) is 147C (ish) so, if the steam were limited to the boiling point, and the boiling point were 100C, then that could work, but I don't think the boiling point is 100C, since it's pressurized. Based on things I think I remember you saying in the past, 20 is a decent high estimate for the pressure, doing a lot of incorrect things with a graph and some math I'm really unsure of, the boiling point at 20psi would be 118.9C? But then is that the temperature of the steam in the steam chest
Just an ask, would an end stop for that little vice have been a worthwhile investment for future builds, seeing as how it wasn't worth it for this set of parts?
Hi quin must say this is getting exciting really inspired by your work. The progress has been fab and always use your guide as a How would Quin do it if I’m not sure. Deffinalty a “practice- chooch” .I have been building my own loco and achieved an “auto chooch” at the start of the month(my page has a video)I was bouncing off the walls that day in excitement after, my build thread on model engineering clearing forum
Blonde I have a question’ I’m considering buying a lathe. However I’m on a budget at the moment. I’m considering a creworks 9x30 lathe. However I am skeptical about the product , also I feel a need to buy something ahead of any potential tariffs that may also be a detriment to my purchase. I am mechanically inclined but wonder if I’m getting in over my head. I’m not sure if it’s good or not. Any suggestions???? Any other thoughts would be great…. Thanks for your content!
"Keep sprocket wide" 🤣
How about that- someone does read those. I’ve been putting ridiculous text in there for years and never knew if anyone saw it. 😝
@@Blondihacks
Yep, it is much like the subscribe
" easter egg " in This Old Tony videos !
👌🏽
You're very eloquent Quinn. The way you speak is as much a part of the enjoyment I get as I do from watching you work.
I've often wondered if Quinn should start up her own ASMR channel. I could listen for ages!
Words cannot describe how much I love this series.
Beautiful work Quinn, thank you so much for having us be a part of your project.❤
The excitement builds towards the ultimate choochification. The construction of the boiler is now but a dim memory, now overshadowed by the beauty and intricacy of the fiddly bits.
An acrylic cover for running air might be interesting when demonstrating timing later. And show them off a wee bit more.
Quinn - great to see it coming together, bit by bit!
At 18:48, behold the elusive Petit-chooch! A thing of beauty. Well done again Quinn.

The start up and running of this will be awesome !
Best cold opens on the internet. On TH-cam. On hobby machine channels. :)
You are an amazing teacher. Thank you.

So many beautiful fiddly pieces! (Under the current circumstances it’s refreshing to see a Canadian quarter.)
I am enjoying the videos and I am also happy to see the little Wilton being used!

Great work, Quinn. You are a true inspiration. God Bless. o7
Did we really used to be better at keeping track of things or did we used to be overconfident?
The shaft fitting into a counterbore also improves the strength of the joint.
Love the background view at 8:08 👍
So nice how it's all coming together! ❤

😂😂😂😂😂😂😂😂😂😂😂😂😂
A beautiful finish on the valves - what hobby machinist dreams are made of.
I’m loving this. I have followed the project from the beginning and watching you build each and every piece amazes me.
15:08 😂 Thanks! I would have wondered what that was in metric otherwise 😄

Pretty exciting progress!
Beautiful work Quinn. Thanks.
Outstanding machining work!
Steam locomotives are Engineering artwork! Looking great.
No problem, now you have a small paper weight which could've been a future fly valve
Great video Quinn, looking forward to seeing more of the linkage and you sort out the timing. 'Clevises' apparently.
As always great work colleague👍👍👍👍👍
Clarance and Shirley-I met them on an Airplane once.
And we have a quarter chooch!
Nice.
Thanks, and Meow to Sprocket.
Thankyou so much for your fun entertaining funny videos
This video has given me the inspiration I need to complete my project. Thanks! 😊
I know you release a video on this project every two weeks. How far ahead do you work? do you have several weeks of it filmed and just cut for length? I get into projects like this and I can resist just going ahead full steam. :D
You are an excellent model builder! Thanks for sharing 😀
I can't wait to see this come alive
Excellent work, Quinn. Needs moar Sprocket!
Keeping meat parts away from fast moving abrasive surfaces and sharp edges is always preferred.
I've been waiting a long time to see the values made, thanks :)
Great video as always. I only have one little critique: they don't come out often enough, I think I'm addicted ;)
Keep up the awesome work.
Quinn
Great valves!
Nice work Quinn.👍👍
Keep them coming! It took me a while to warm up to the steam engine videos but now I enjoy learning from them also.
Phantom Chooch ? Anywho, just commenting to feed the algorithm Quinn.
Thanks again and Best Wishes !
Fine work as always Quinn.
That tilting table is an object of serious jealousy on my part.
@@jeremylastname873 I used one at work from Grizzly and it worked ok as well but it didn’t have the worm gear adjustment. Does the one you bought have that feature and if yes, how do I find one?
@ Never mind, I found a few online, but thanks for the info.
Really nice surface finish esp on the angled faces. 👍
Awesome valves & valve clevi 😅 Great video, Quinn!
Its really coming together ❤️
Gorgeous work! Coming along nicely.

It works like a strap clamp
I can't wait to see it run for real! ❤❤
Great job, as always!
One of the tools i have is my tilt table , love to work on it. Go Sprocket , hahaha
As always, thanks for sharing.
I’ve finally seen you do something within my skill set - separating two pieces of brass with a hammer 😢
Delighted to be present for the nascent ur-chooch.
SOH/CAH/TOA!!!!!!!!!!!!!
Woohooo!!!!!!! Love it, the only thing I remember from school LOL
Thanks Quinn
Just fascinating! And those are beautiful.
Great work Quinn

amazing work 😃 thank you! 👍
Yay!! It's Blondihacks time!!!
i always look forward to your videos
A fascinating video 😊
how dare the algorithm keep this hidden from me for a whole 16 minutes
my Sat. is now complete!
....justa "choochette" this time, but we look forward to seeing this little loco in steam.. 🙂
Holy Intecracies!! Love it
congrats on the first half of a chooch 😀👍
Early signs of life are still signs of life!
Thanks! ❤
what species of valve gear will the model have?
are we going to see tiny walschaertz valve gear made?
is something more like baker that's more popular in models due to pin joints?
or even a specialty gear for the heating and scaling issues that admits more/less steam than normal?
Came for the hacks, stayed for the chooch.
Clevis plural = Clevi…which is where we get the Dutch phrase : “Clevi-clogs…”🤭❤
😭😢😉
had a good chuckle at the pacman joke
Ohhhh boy it's so close to choo chooc!
Terrific!
rip scrap valve, never had a chance to chooch 😢
@1:21 I've seen This Ole Tony do that same thing! XD

Very nice
Think your "old person cheater" is totally legit, I use it all the time, like " knife" and "fork" such a help😇
Video idea? Magnetic endstop for the vice on the angle table thingy?
Can you stack slitting saws? I have to try it to see how it would fail.
That was a wonderfully stout mill bit you got that great surface finish with? ( score one for us , ahem, “barrel-shaped” individuals…😅)
"A proto chooch" LoLoL
Just an ask, would an end stop for that little vice have been a worthwhile investment for future builds, seeing as how it wasn't worth it for this set of parts?
3:20 - here in the UK that's called a slot drill.
mini chooch acheived!
