"this is my excited voice. can't you tell" got a laugh from me 🤣
also *crickets* 😅
These videos are a gift for the wit, the wisdom and the charming company!
"valving" is a cute synonym for "actuating".
It is a real pleasure watching younger folks getting into a very old hobby which has generated "engineers" for centuries in the true meaning of the word. Building an engine informs a person on the intricacies that can't be known any other way. "Our engineers" designed and built our Nations such that we have enjoyed the greatest boom in Man's history. We are the engineering outcome of "The Roman Empire", Great Britain through the 18th century, and the U.S. through the nineteenth and twentieth. I've enjoyed "machine work" since the early sixties beginning with a hacksaw and files.
As a sailor, I really appreciated the conversion to nautical miles...really helped me understand just how small a part it really is 😂
Great video. Good example of the hard to explain skills a machinist needs.
Taking a simple looking part and figuring out how to actually make it. The things no one will spell out for you and have to figure out for yourself. When my kids ask me what I do at work. I can show them this. All day I make one off strange little tiny parts that are hard to explain what they even are. But the process of making them is why I love my job.
Keep it up.
Hi Quinn, as a machinist for 40 plus years I see You have the the gift of patience and detail for the next operation.Your set ups are Great.The set up as You know can take more time than the the cut.Keep making those chips,You have the Gift of Creation.
I was SO waiting for you to say "tabby, tab, tab" at 3:36.
My history of knowledge of steam engine kits:
1: "Oh neat, it's a kit that you put together."
2: "...Oh, wow, you basically have to remake every part almost, you just get the rough shapes."
3: "...Wow, you have to _figure out for yourself_ how to remake each part. It's more like a machinist's puzzle than a kit."
"1.3e-6 nautical miles"
Love it!
Here in England we had a kids tv program called Ivor the Engine and the sound of your test run sounded just like the noise Ivor made which brought a smile to us oldies great project learned a lot thanks 👨🏻🏭🇬🇧
LOL, I had a big smile on my face too. I really like the sound already.
Perhaps not the best method, but you could measure the gap in the clevis by stacking feeler gauges.
Love the vids.
Or drill rod; the shank of a new, never-chucked drill bit of the correct size would work.
Very, very cool, Quinn! (this is my excited prose)
A new Blondihacks video AND a new Clickspring video on the same day?!? It’s like Christmas came early!
What I learned today, the parallel squishy technique.
I was not looking forward to this series but have loved it. I have learned so much. You are a tallended lady with good machinist skills as well as a good educator. Thanks!
OK... I won't mention that you could have used feeler gages to measure a small narrow slot (the crevice in your clevis :)) because so many others already have. So... just ignore that first sentence please. There are many other ways to measure small insides at your disposal. Drill bit shanks and a micrometer. Even turn down a nub of metal on the lathe until it just fits the hole or slot and mic it. In general some sort of gage pin or block either of known size or a size you can measure.
The usual thing for small clevis pins is to make the hole of the center piece slightly undersize so that it is a press fit (or tappy-tap-tap fit) and holes int he outer piece as slightly oversized. This sort of arrangement is preferable to making the outer holes undersize and the inner one oversize. Also better than making all three holes the same size, loose or snug fit on the pin.
The engine is beginning to look really good.
And this is my excited font, I am super excited to see this project progress. I really enjoy watching you work on this.
I could listen to your voice all the time excited or not.
Got to love it when the parts come together. I’m enjoying the vids! Keep ‘em coming 😎
That two parallel trick to square up the brass piece vertically....NICE! I could have used this several times.
So satisfying seeing all your hard work coming together!
Another great one Quinn. Just goes to show that you don't need a huge shop or tool crib to make a workable engine!! I think you are doing a fantastic job!! Take care and be safe!!
Rex Kruger says y'all are doing a collaboration. Outstanding, 2 of my favorite makers making together!!!!
It’s gonna be cool!
Machining in nautical units; that's when you know its time to lay off the grog...
I thought that was a nice inclusive touch for those machinists who've only just come ashore.
I must give you kudos, as is the tradition, for that little clevis (that would be the torturous part for me due to the size of the part and the law of diminishing dexterity). This time, the cool part was hooking up air and seeing signs of life. Really looking forward to watching it putt and pop on its own. Keep the vids coming! Thanks. 😎👍
Hermoso el trabajo que haces. Pero a los locos que nos gustan ver estos videos, nos gusta el silencio o una tenue música de fondo. Te felicito por el emprendimientos y por la precisión. Saludos desde Argentina.
Yay! I’ve been waiting all week for this. I already have quarantine cabin fever and for some reason watching steam engine videos has turned into an obsession for me. Thanks!
The crickets tell me you're not the only one with quarantine cabin fever. :D
Have you found Kieth Appleton's site? Don't go there unless you have a few spare weeks. A good openness to quirky British humor helps as well.
Jim McCorison yes, I’ve spent a few hours down that rabbit hole too...
Merry Christmas, Quinn! Thank you for all you do.
You truly do have the skill for machining. Love it. Come work at our shop. Looking for a new manual machinist! 😁
Always a pleasure to see your vids on how you accomplish the projects
Your working with small brass parts made me think of Chris and his Clickspring CZcams channel, and he is back on the antikythera mechanism after much research and the publishing of a paper, yay! Can't wait until the next construction video after long delay pops up! The new one now talks about the research and controversy and data gathering and conclusions and publishing a paper about one of the wheels.
This is why I love your work and am happy to give my (meagre) support on Patreon. The tip about turning a small diameter part in in sections is GOLD! I can use that one right away.
Awesome! More alive than before, brilliant!
Love you videos! Copper allows and some stainless actually are the total opposite of steel. They anneal when quenched. Keto up the good work!
definitely the best series on CZcams ! I did my best but switch to French... bravo, voila une vidéo qui fait du bien ! merci, Blondihacks and a single malt, what else ?
Such a cool project. Major progress today! Can't wait to see the next installment.
I'm so glad I waited a few days to watch this episode. I was amply prepared for "excited voice". It was great. Thank you.
Clickspring + Blondihacks on the SAME DAY? Is the world ending?!
@UCeoSAHWsqcpkuLFFC6Teb-g Not really, he explains the advances of the last year, which he spent (with a team of experts like him) investigating aspects of the Antikithera mechanism. I don't believe that's a repost.
The valve mechanism set up is very similar to our (Pichi Richi Railway, Australia) YX141 steam loco, built about 1890. The mechanism is on the inside of the main frame, along with the excentrics , while the cylinders are on the outside.
How exciting! I am enjoying watching you build this engine, and I'm learning a lot. I always look forward to you videos :)
I love these videos. Your humor is perfect for this kind of video, too. I do CNC in wood and light aluminum on a square profile rail steel and aluminum extrusion router, but you have inspired me to look into getting a lathe. Than you so much for your hard work in producing these.
Not sure if I ever mentioned how awesome I think you are. Go you!!!
Nicely done on those small parts.
If I do this project that's one of the things that concerns me as there are so many ways to do those which means there's lots of ways to wreck them and a few ways to get them right. Leaving the stock material intact until you've done most of the machining was done will help a lot of people. Well done on that.
Getting into Click Spring territory with the small brass parts!
I noticed you using a squirt bottle for the WD-40 when drilling the .063 holes. A trick I use is to get a few 20cc medical syringes and some 16 gauge blunt needles from McMaster-Carr. They give you much more control of your fluids. It's great when you just need a drop or two. I load up a syringe with each of the fluids I use so they are ready to go when I need them. Some chemicals will cause the rubber seal to swell so depending on the fluids you use some syringes will be single use only and others can be used over and over.
Great idea!
Love that excited voice, and just think you are almost done...woo hoo. Sure is looking good.
Very nice, great to see the project coming along really well, thanks for sharing.
You sound very excited lol thanks for sharing your build so far I have to say that you and Steve summers are my favourite CZcams machinists
Being a guy that works on the River Mersey the nautical measurement was most useful Quinn! TFS, G :)
This series has been my gateway drug to this channel
Love your work Quinn
Excellent as always!!
I’m enjoying every bit of it.
Wow... Really small fiddley parts... BTW: This is my excited commenting voice... can you tell? LOL 😎😁
A Blondihacks video and a new Clickspring video all in one evening? Spoiled is what we are! Deeply satisfied we is. Les in UK.
(Edit) AND a Ca Lem video in the same day, too. Wow! Where’s ToT to make it a complete party?
You can tell she's excited. It's a steam engine. Who doesn't love seeing steam engines work? Especially homemade ones?
THANK YOU...for sharing. Watched and very much enjoyed.
Turning half the pin is a must have trick :o) If you are a complete smarty pants you leave one bit bigger so it’s an interface fit in the clevis.
I could watch that piston go back and forth all day...
1.3 E-6 Nautical miles!
Quinn, that nailed it for me!
Awesome!
steve
I didn't know they make reamers that small. I have to get Set for my shop. Awesome video.
Very nice technique on the split block holding the square! Steam engine is shaping up very nicely. Cheers and seasons greetings!
Really nice job Quinn!
Loved the “tab A into slot B” comment that’s how we explained “IT” to our son, lol. Great video!
Getting close now!
I always like to see yet another way to square up tricky parts without needing half the Starrett inventory in a drawer, realy useful. Also pleased to see a very British level of exitement , keeping calm and carrying on. Oh BTW, Doubleboost (John Mills) has the technical term for that loose fit . ''PWS''
Nice idea using the parallels to square the part
Good job Quin! Enjoying your videos
This is such a cool project, you make it look so easy :)
for a machinist, She has some elegant fingers and a super excited voice!
Nice job. Thank you Quinn.
Great video, keep up the great work
I don't think I have ever heard about the two tabs...... wozzzzaa. But you got a lot of mileage out of A&B comment.
Thanks for the awesome videos! The brass looks "tender" to work with. Steam stuff and hobby machining is so cool!
I believe that the holes in the Clevis are supposed to be different sizes to give a slight press fit in the center part. But, yea, inky dinky parts.
Very clever clevi work.
Great milestone! It looks to me like the timing is off but I don't know much about steam engines. It also looks like it's adjustable, so I'm eager to see the process you'll use to adjust the timing.
Timing is not set
Nice, just in time for diner!
Looking good .
I love your excited voice (no exclamation point to finish my comment)
That is fabulous!
Thanks Quinn
You may be able to use a small punch and set the clevis pin like a rivet. It will swell in place.
Cool. Nice job
I love the videos , keep them coming. Good work.👌🎅🎄❤
Merry Christmas
Professional work 👍
Truth to tell, I thought you sounded a touch more excited describing the slip fit between the tab and the slot, just before the crickets...but I could be projecting.
I was also all excited:) Instead of locktite could you peen the pin? I mean have it out of the clevises and hold it and lightly peen one end almost like a rivet, but less. Then slip it in and hopefully, that end is slightly larger and you'll need a pair of pliers padded with copper to encourage it in the last bit.
The devils in the detail! 👏👏👍😀
The engine is properly puffing!
nice work
Congrats on the first signs of life!
Hello Quinn,
I hope you are well, nice work today and also a nice excited voice...
Take care
Paul,,
New Blondi video pop up >> click „like“ >> watch
I’m sure there are other videos about center finding (click spring comes to mind), would you mind some day showing center finding techniques for all the various ways you do it? This noob absorbs your material and like your presentations.
Well done.
I am glad you didn't call that part a 'cleevis' . As for the pin, my grandfather would say "as precise as necessary, not as precise as possible" He was a shipbuilder...
Love it 😀
Tab A into slot B. It's not for everyone, but no judgements.
