Making Cylinder Heads - Big Steam Engine Build, Part 9

[@rustyshackleford928]

"This is not a critical dimension, so of course I nailed it" Cracked me up. Thank you Quinn, I learn so much here.

[@hubertheiser]

"70% of the time it never lets me down." Made may day 🙂

[@leeklemetti1887]

That 30% loomed again!

[@tomp538]

Ha! Nailing non critical measurements is like welding. The best looking weld is always not seen in the finished part. And thank you for making this video and narrating with your calming H.R. voice.

[@Thoron_of_Neto]

I worked with pipe welders before my current career field. I wouldn't say all the best looking welds don't get seen, but thats only because that's what those guys do 12 hours a day 6 or 7 days a week, every one of their welds comes out looking like ice water in the Sahara.

[@LaddGardner4]

Alignment pins -- along with the lucid explanation for their use -- much appreciated, Quinn. Beautiful video.

[@ChrisHiblerPinball]

I love the humor Quinn…”nothing to see here”. The time you put into these productions must be immense.

[@sazafrass]

Haven't finished but your intro just made me think "in the business, we call this foreshadowing."

[@RonCovell]

Great job, Quinn. It's looking more like a steam engine every episode!

[@bandana_girl6507]

"Why didn't you include alignment pins in your drawing?" "Who would ever take it apart after it's built?" "Perhaps a machinist who needs to fix something." "Yeah, but what are the chances a machinist is going to buy this?" "You sold it as a rough-cast kit." "Oh, right."

[@peterpowell4821]

I would add alignment pins to the "separates us from the animals" adage 🤣

[@mrimmortal1579]

And also the fact that we’re not afraid of the vacuum cleaner.

[@Thoron_of_Neto]

Personally, I'd add that they're "what separate us from the other animals" but that's because I'm a friggin nerd lol

[@g.tucker8682]

Damn, that thing is big! One word: pinstripes. Thanks, patrons.

[@matthasaname]

One of the things I like most about this channel is the length at which you go to hold a part and how you explain why this way is needed this time vs how you did it last time. I appreciate that nuance being an outsider. Whenever I finally get to use a lathe or a mill someday, I will surely remember the lessons I've learned about the importance of holding the work properly, securely, and with order of operations in mind. Earned a sub.

[@KerbalRocketry]

"because chamfers are what separate us from the animals" made me laugh out loud

[@metagoat]

Very satisfying to see it all carefully aligned. My granddad woulda just eyeballed it while working through a case of Budweisers.

[@neorecormon1769]

sounds like a cool grand dad :D

[@russellstarr9111]

I fully agree with pinning those parts. Wise decision!

[@brandonlewis2599]

"I really have no other explanation for this, other than I didn't think of it". And that is why I love you.

[@pst3615]

As a machinist myself I've been watching your videos for some time now and I really like your way of thinking. setting up a part is the most challenging part of machining and you're doing a great job as such.

[@ChristopherTate]

"Scoundrel Blend" A++ YES

[@jeremylastname873]

As far as a design that “lacked” alignment pins, they probably best things to meet things, and then locked them down. If you can’t make it perfect, make it adjustable. If you make it adjustable, make it lockable.

[@ssskids123]

70% of the time it never lets me down……..thank you for that!

[@georgewolf7063]

Watching you work makes me feel okay for being human, yet your machining is lovely as ever! The engine is coming along wonderfully!

[@megger607]

Thanks!

[@jrkorman]

Nice. I like the pressure turning fixture. And now that you're done, you have a tiny, little disk sander 😉

[@michaelwest4325]

As always you inspire the hobbyist to really do some professional machining!

What's that, woodworking tools saving the day? :D

[@eliseojacome3031]

Well, I was watching a different blondiehacks video about tolerances and now I’m here. 5 stars

[@campingstoveman]

Every time you make a part for your engine I remember my Grandfather in his workshop :-)

[@murrayblack4371]

I am not a machinist, but I can not stop watching your progress on this project.

[@quintrankid8045]

I second this. I am also not a machinist, but I really enjoy learning how things are made and I enjoy seeing how mistakes are handled.

[@murrayblack4371]

@@quintrankid8045 It gives me confidence to make a mistake, it can be fun fixing it.

[@solarguy6043]

Another great episode! A machinist's best friend is a hammer. Of course, it has to be a special precision machinist's hammer to get those great results. Nothing to do with skills and practice.

[@brianhostak3961]

I love the way you think out of the box !! Thank you for your time and great videos !!

[@AerialPhotogGuy]

Hi Quinn, When machining shallow bosses, try machining future pressure pads slightly larger than the finish size of the boss so you can use the pressure pad OD for measuring with a micrometer, for future reference of course. :-) I've used the above method in the past with good results but whatever works for you works. Nice work BTW :-)

[@joell439]

👍👍😎👍👍 - thank you Paterons

[@davidwhite5972]

From a maintenance engineers point of view, well done for adding the alignment pins.

[@pebrede]

As per another comment. Taper pins are a more satisfactory method of capturing alignments, in my past life we aligned several thousand horse power engines to large free standing many ton flywheels and generators to 0.0005” running concentricity and locked them in with 3/8 tapered pins, with withdrawing holes tapped into the end, for repeatable maintenance procedures. Also, if you have a rotating center with interchangeable points, use a ball in place of the pointed tip to hold the pressure pad, this will then self align and hold the part more securely. Great series and I look forward to its completion and first run. Take care.

[@nmarkose]

Can’t wait to see the final product.

[@bostedtap8399]

Ouch!, great recovery Quinn. Nice high quality work, and excellent techniques. thanks for sharing.

[@martinhughes8500]

What a lovely combination of precision, strategy, humour and humility. I feel for every mistake, blunder and miscalculation but ultimately for the sheer pleasure of producing components that fit into a functional machine. It is great watching your videos and your narrative adds so much more. Best wishes

[@slowwerthensnot]

Love the attention to details, so enjoying this series!

[@bobkelly2447]

You'll need to make a go-kart to mount that steam engine on now Quinn !!!! and a boiler that can keep it pressurized too ! it's going to go through alot of steam !!! good work as always ! thank you !

[@bobkelly2447]

of course you COULD put it in a little motor-scooter...too... that would be something to see ! only one of it's kind LOL....

[@lewisheard1882]

Ah, I see I still have lots to learn from you about machining, Quinn. Cuz I would have guessed the reason for not spot facing and drilling in the same setup would have been “because shut up, that’s why.” :D

[@jackpledger8118]

Really nice to see a machinist (engineer) accurately machine all the parts to a steam engine. I've watched Keith Appleton measure with match sticks and hammer handles while using his (calibrated eye) to align things so long I was beginning to think steam engines were supposed to built sloppily.

[@mrimmortal1579]

To be fair, Keith isn’t actually “building” steam engines, only just repairing them. Plus, he’s been calibrating that eye ever since they invented steam, so it seems to work very well for his purposes. Lastly, while it’s nice watching someone do the work with a machinist’s keen eye for tolerances, steam engines really do require a good deal less precision to run than an internal combustion engine. Granted, the higher the level of precision, the more efficiently a steam engine will run, but it will still run with a great deal of “slop” in the moving parts.

[@obe726]

Very smart way to hold those parts nice going

[@leighmackay7486]

Beyond informative you’re delightfully entertaining, Quinn. Thanks for sharing.

[@gillywild]

Getting the bottom end aligned must be really important. You see men doing it all the time >_^

[@henrikstenlund5385]

It is always useful to follow your channel and see some interesting details and methods. Thanks!

[@PeterWMeek]

You have no idea how happy I am to see those alignment pins. The only thing that could make me happier would be if they were TAPER PINS. Straight pins always have some clearance; taper pins get driven in until there is no clearance. It's not too late; but you would have to through-drill the feet of the frame to have access to both ends of those holes. For long drills (and reamers), you need a system where you can make ad hoc extensions at a moment's notice from any rod you have handy. I have such a system, but although it is quick enough to execute, it is a bit complicated to describe in a comment. I'd be happy to discuss it with you (or anyone else interested).

[@ironhydroxide2]

@26:45, you could have left the tailstock boss a bit large, turned the tailstock boss at the same time as the part, then measured further out. Granted it's aluminum vs cast, but would get you quite close before final fitment.

[@DavidLindes]

Isn't this timestamp just the end of the video? Uhm... why? :) :)

This has become best part of my weekend. And now I’m looking for everything in my shop that could use alignment pins.

I genuinely love this channel so much. I'm not even a hobby machinist, because I already have too many hobbies, and as much as it appealed to me in college, I didn't change my major to do more of it, because aviation was my dream. I still catch as many of your videos as I can because of your humor, and the sheer relaxation that comes from watching you do these machining projects! Thanks for making these!

Good move,pinning the parts.Many years ago, I built a Tiny Power “M” side crank engine with a Stevenson’s reversing link. I soon realized,if I ever needed to work on it,reassembly would be a nightmare. I decided to to do what you did. You won’t regret it.

[@coolmakers3150]

Quinn, I am so addicted to your videos! Your knowledge, workmanship and delivery of information it top notch! You blew my mind with the blind hole alignment pins! And then offsetting them so the parts will only go back together one way! I love the way you put together and execute your order of operation. Great work!

[@howder1951]

Nice work Quinn, I love the size of this baby. The spot face makes the cast surface pop, for me anyway. Enjoyed, cheers!

[@fna-wrightengineering]

Awesome work as always, Quinn. The alignment pins are a very good idea... Given how complete the plans seem to be, I'm genuinely surprised they're not an included feature. In this, as in all your videos, I enjoy and appreciate you taking us through both the forethought and hindsight of your thought process.

[@marcusFZ6]

That little thread that you added to the middle plate on much bigger engines is called the stuffing box. A very long time ago when I was just learning about large 2 stroke diesel engines, I fell asleep inside the stuff box area whilst doing a cylinder change-out. Yes the area was large enough to get inside and install the springs and seals. Funny little story on crosshead engines. Engine in question was a Sulzer RND90

[@knickebien1966]

[@michaellinahan7740]

Quinn, thanks for another great video. I think this episode epitomises why all us 'backyard engineers' do what we do; it is the problem solving and having to think on our feet to complete the job as efficiently (not always) as possible that gives us the enjoyment factor even though there is an occasional curve ball thrown.

[@billdenis7478]

Noticed that some of your super glue at 14:11 was still wet. Next time you use super glue accelerator on one piece and glue on other, you will get complete bonding. Super glue is activated by moisture, no moisture no activation, also storing super glue in your refrigerator will extend its life tremendously

[@leeklemetti1887]

Thank you Quinn, I am still learning. This is a wonderful build.

[@HyperactiveNeuron]

Too many bosses leads to micromanagement 🤣 The super super glue would totally happen to me. Oh that and absolutely nailing a non critical measurement.

[@eugenefisher2965]

At 11:10, toget an idea of contact before using superglue, try pre-pressing with silly putty first to determine contact points, where the silly putty is thin would indicate closest contact. Removing the silly putty from the casting surface completely before superglue might be tricky.

[@ForfeMac]

Considering the silicone oil in silly putty wouldn't be conducive to glue adhesion, something like modeling clay would probably be better.

thoughts on straight pins vs taper pins for alignment? I guess having the tool steel and having to turn them yourself lends to using straight pins. Looks so good! If anyone sees a partially blended face, no you didn't. 😁

[@josephpadula2283]

Most of the equipment that I work on with alignment pins are taper pins And drilled in at an angle too not straight down.

[@richmiller2711]

When you use the tailstock like that, it helps to either super glue or use double stick tape to put a piece of emery cloth on the drive part. The emery cloth id slightly soft and makes up for uneven surfaces. use automotive wet-dry paper for plastic parts or precision parts. good video, as usual. Oh, ya, use the thin 3m tape for smoother parts and more precision. I've been doing it with tape and super glue for a looong time. thanks for your videos.

[@ratdude747]

One bit of constructive criticism: when dealing with dowel pins, when possible make the press/loctite side a through hole. That way if you ever break a pin, it's easy to hammer it out without having to drill/EDM/etc. to get the pressed in half out.
