The James Webb Space Telescope launch AND Quinn's boiler making steam on the same day? Now that's what I call an Industrial Revolution.
Who would have thunk an adequate little safety valve would have been so allusive? A long road but seeing the engine run on live steam had to be VERY rewarding.
Essential milestone indeed! All the rest is housekeeping (still necessary, though). Well done, inspector signs the paperwork, drinks all round, etc.
Yay! It's Blondihacks time!! Merry Christmas, Quinn!!
Way to go Quinn, it's a thing of beauty
Apart from Quinn's depth and breadth of knowledge and sheer virtuosity on machine tools, her blow-by-blow commentary and Sahara dry sense of humor well exceed the price of admission. I'm addicted to this channel.
Choo choo!
Thanks for the reminder about CO.
And thanks for giving your viewers a (blurry) look inside one of Kozo's groundbreaking books. The wealth of excellent illustrations continues through the whole book, and series. The best.
I liked your fix on the original valve . If you have room you should ad a short helper spring . That won't seat the ball but will ease the pressure for the mane spring to seat the ball
This is where I learned what hysteresis is, which came up in conversation today about sump pump controls. So thanks again for that.
This has been a most enjoyable series this year: Watching Quinn build a thing that I will never in my life attempt to build, all the while learning so many things about the process of fabrication and machining.
Heck yeah the moment we've been waiting for!
Great Job Quinn!!! Love that you dont mind having a go at modifying and making new safety valves etc :) soon you wont be buying any parts at all! People will be asking for a Quinn Co. Steamomatic Boiler Kit soon enough!!!
That is one beautiful boiler, I really like the vertical form, and that will be great with a feed pump added to your engine. Thanks!
Every time I would see that the week's video was steam I would groan. Every week I watched with anticipation and excitement and finally contentment with the machining, theory, and humor. Congrats on the completion of this project. You are a very talented young woman. Looking forward to the next project. Paul (Patron).
Thanks and Happy Holidays.
I love that you include everything that didn't work and the progression to the things that do.
Fantastic, congratulations Quinn so good the hear your engine running on your new boiler
Hi Quinn, just wanted to say what a beautiful work you’ve done! I do wish to comment on the mention of this valve being used as a pressure regulator valve at ~5:40 point. Boiler Safety Valves are safety devices and not part of normal operations. If a Fireman is causing the the Safety Valve to lift on a regular basis it would likely end his employment. Boiler pressure should be regulated by matching the firing rate with the Steam output. I understand that a quick closing of the steam stop will cause a pressure spike and subsequent Safety Valve lifting but this would be the exception not the rule. Marine Boiler Safety valve lift pressure is set at 10% above the MAWP (maximum allowable working pressure) and adjusted by changing spring tension. The Blowdown is adjusted by moving the huddling chamber or seating ring. Valves are designed to blowdown below MAWP even while at max firing rate to be assured of protection of the personnel. There are good cutaways of Marine Boiler Safety Valves on the internet.
Though I'm a cabinetmaker by trade, I love watching you work and learn on small items. Strangely enough, another favourite UA-cam channel of mine is Cutting Edge Engineering, who tends to work on oversize machinery for a living.
Congratulations on a successful startup! It's so satisfying seeing both of these projects come together. I admit I was a little concerned (ok, a lot concerned) when you started modifying the safety relief valve but my only experience with a boiler (somewhat) like yours is a boiling water reactor; it's amazing how easily you can spook nuclear people with steam and pressure vessels, even tiny ones :)
I'm not sure why EXACTLY I'm so fond of your channel. Your a far better teacher than many, your wonderfully articulate, many of your posts are about just what I'm dealing with, and you make stuff I thought I could care nothing about, yet you have made me interested!! (E.G. steam stuff). A Joy filled holiday season to you Quinn!
Owing to family holiday nonsense I was unable to watch when this episode appeared. It's just as delightful and satisfying as I hoped it would be. Thanks and happy new year!
Merry Christmas Quinn! Was hoping for a new "Night Before Christmas" story for machinists ; ) Will view last year's. That was so creative!
Hehe, that was exhausting to produce so there may not be another one. 😁
@@Blondihacks I bet it did take a few hours to make that video
I'm watching your latest project on a boiler. I am impressed to say the least.
The lifting pressure of the safety valve is going to be the port area the ball is blocking but the closing pressure will be the projected area of the ball (or the ball plus carrier). With the ball in carrier design, you probably need to have more than the two filed flats so that the carrier is not acting as a pressure restriction. Perhaps more holes in the top too, so the only pressure inside the valve is from the steam passing through. (Thoughts from a bloke who has not done as much with steam as you...)
Yaaaaaay! 🎉🎉 🎉 🎇 🎇 🎇 That's awesome! Well done, I've watched along with you building it and you've done a great job. Bet you're stoked as (I was) when that flywheel turned by itself for the first time. 👏 👏 👏
A couple of methods I've used to true up a flywheel that is off center. 1) use a round file to remove material inside the hub. The outside may need to be recut to get rid of hump after adjustment. 2) bore and sleeve the center hole.
Neat!
And Merry Christmas and a Happy New Year!
Thanks, and Meow to Sprocket.
Now that is quite the Christmas present. Congratulations on first Steam.
Question you might lookup industrial safety valve and copy it to fit the size of your boiler industrial valves have a settable blow back setting. If it goes off at 60 psi you can set the blow back to close at 55 psi. I have fried industrial for over 42 years the biggest was 200,000 pph. O yes Merry Christmas, Quinn!!
Wishing you a very Merry Christmas Quinn!🎄
Steam and torque gets you coffee, I might point out 😊
Great boiler making. Merry Christmas.
This is awesome, I love that hiss-pump sound of of the engine. I kind of want to see you charge a phone with it :).
Very nice! Can't wait to see it all piped up. It is recommended to replace the steel ball after using a hammer to seat it.
Great job! So fun! I always use a least 3 recessed grub screws on flywheels, that way I can true up most any wobble
That is some achievement. Yay!!!!
My experience with safety valves for boilers are, that once they pop they don't stop.
On the plus side, it looked kind of homey to see that string of smoke slipping out of the evacuation pipe.
We always tried our hardest not to activate them, because everyone knew that they would be leaking until next shutdown and revision.
Good times! :)
@@markfergerson2145 I have asked myself the "in this day and age" argument myself many times :)
The safetyvalves construction might be hard to explain in text, but essentially in/out take valves from an engineblock, size XXXL and then a spring at 25 bar attached to it. Technically the spring was pneumatic pressure, but principle is the same.
Probably crud as you say, but also these sort of things need maintenance which always is the first thing to go during cutbacks. The valve might seat good enough in one position, then it blows and rotates a bit and will have to be battered down, I imagine.
@@PhilG999 we have the same rules in Sweden. Also, one valve must be able to deal with 4 times the production, and always at least double valves. They must be situated in such a way that when you turn of one, the second will always be on.
There is more to valves then people think :)
Congratulations 🎉 and Happy Festivus
Next, a hard-rock gold mine or a grist mill to make use of your motor? Great stuff, love your videos.
Consider heat soaking your flywheel in your kitchen oven at it's highest temperature for a couple of hours with a slow cool-down (say 50°F, wait 15 minutes, repeat until around 200)
Happy holidays Quinn! The boiler looks great. Also, THANK YOU for discussing the importance of the CO detector! I work in life safety, and love so see people who take it seriously.
A Blondihacks video on Christmas day? Its a Quinnmas miracle!
Thanks Quinn - merry Christmas
Very nice job the boiler has turned out beautiful 👍👍👍
*This* Revolution was televised! (sorry... just couldn't help myself.)
Happy Holidays Quinn!
I have really enjoyed this series with ALL the details you have given.
Props for using the the word 'hysteresis' correctly... heck props for using it at all!
OK... leaving.
The bandsaw disassembly part(s) were the best!
Nicely done. It's lovely to see that boiler all put together with the cap and chimney. It looks so official!
You made it!!! Finally well done now bigger and add a generator set and make useful power!!!
Elegant, fit for any steampunk movie.
Joyeux Noel 🎄
18:20 Legend! That must be soooo satisfying!
Congratulations Quinn! Thank you for sharing this with us. Happy Holidays to you and Sprocket.❤
A vous aussi bonnes fêtes
Its not complete but the fit and finish already surpasses the electric model. Happy holidays.
👍🏻As a carpenter for over forty years all I can say is "Way to nail it Blondie"! Happy Holidays.
This comment dovetails nicely with what I was going to say.
Thank you. The whole series has been very educational. I enjoyed every second.
Beauty!
I am really eager to see what you do with the feed pump...something I've been wanting to learn more about for a long time...thanks for sharing!!!
Merry Christmas to you and yours.
You mention that with a (model) steam engine creating heat with combustion feels satisfying in a way that creating heat with electric energy doesn't. I agree.
Building a model steam engine is a celebration of ingenuity. Electric energy is _new_ technology. The engineering way to convert electric energy into mechanical energy is by using an electric motor. For a steam engine it is ever so satisfying to use an energy source that _only_ a steam engine can turn into mechanical energy.
I have that same Kozo Shay book. It's a true treasure!
Merry Christmas 🎅 🎄 ❤
From Connecticut
Woot! Woot! Gratz!!!
Nicely done
Quinn, that book, Building the new Shay.
Well, in the hills between San Jose Ca,
and Santa Cruz, is a narrow gauge short
line railroad, Roaring Camp. Fell in love
with their Ephraim Shay locomotives.
(That was in 1969.)
What, a steam loco, with a crankshaft
and universal joints?

Merry Christmas 🎅
And your model(s) are so good. Really great!
You can reduce the CO production of your burner/boiler setup by increasing the air gap between the burner and the boiler. Even if the burner is very near stoichiometric mixture, the cold metal will quench the flame before all the oxidation completes, leaving you with CO instead of CO2.
Best video yet!
Koso’s books are amazing, I gave them to me for Christmas
MERRY CHRISTMAS to all.
Merry Christmas Quinn!
Just goes to show that you should never trust a blow off valve until you have tested it - you can use the same rig you used for the boiler test .
Maybe the reason for the valves not closing is the steam flow is keeping the ball off its seat because the ball is in the end of a cylinder and acting like a piston .If you set the valve up in the mill and use an end mill to cut some flutes in the bore where the ball sits this would give the steam a path around the ball .
congrats Quinn, and Merry Christmas!
$$ + patience, trial and error+ troubleshooting skill = steam project success, nice work Quinn, have a happy new year! Congratulations on the subs, everybody loves you!
Very well put together. Thank you Quinn
What a way to steam into Christmas!
Merry Christmas, Quinn!!
Yaaaaaaay. Fire in the hole!!!!
if you back out the grub screw on the center nut the nut acts as the register for the pressure applied to the spring on the stuart
So happy with this status.
Congratulations! Awesome accomplishment 👏
Very cool project. Thanks for posting
If I'd spent fifty bucks on a valve that didn't work I'd be furious, dunno how you stayed so chill for the voiceover Quinn.
Woohoo!!! Congratulations! Merry Christmas and a safe and relaxing new year 😊
The flywheel warpage is more than likely from the casting not being seasoned before machining. Most cheep castings are shipped with out seasoning. Good luck from the Shire.
Rough machine castings like that flywheel....then leave em outside to weather for a few months...
🇬🇧🙂
Thanks for sharing Quinn, Best Wishes to You and Yours for a great New Year.
Good show, this was a awesome milestone.
Hi Quinn,
Congrats on making steam with the boiler and running the engine on steam. Seasons Greetings to you and the family and you all stay safe.
So Cool!
love your videos, great machinist, very good at diagnosing & superb narrating !
I am seriously loving this project.
For increasing boiler capacity consider using one to preheat and feed the other. Thanks for all the educational content
Merry Xmas....thanks so much for the education and entertainment. Wonderful to see the boiler working.
Very cool. Merry Christmas!
There's no finer feeling than seeing your boiler make steam and your cylinder(s) turn that steam into movement. Well done, Merry Christmas and Happy New Year.
Congratulations Quinn!
Great little engine, love the time and attention to detail - watched every installment. Merry Christmas-!!
Merry Christmas Quinn
Merry Christmas, Happy Holidays Quinn! So rewarding to see your engine running on steam today. I'm surprised that the burner has a hard time keeping up with the steam needed. The engine is not even under load. Well, we'll see where you go as you take us along. Thanks for your generosity in showing us your builds.
Merry Christmas, Quinn. You are awesome! Thank You!
Yay! Merry Christmas, and thanks for your video present to us! It looks great.
Merry Christmas
