[@Sanny987]

Seeing that eccentric turn in the final shot of this video was so satisfying.

[@jimsvideos7201]

I got a chuckle from the impact gun, thank you for that!

[@jackleg693]

Don’t tell the other parts but I think this is my favourite.

[@charlvanniekerk8009]

Absoultuely love you videos and your thinking process. Thank you for being such an amazing youtuber and teacher. Your accuracy and quality withing the world of machining aswell as your amazing sense of humor is extremely admirable and a pleasure to experience. Cant wait to see the rest of this project❤

[@BeachsideHank]

When the hub finally fits inside the clamp the technical description for that is hubba hubba.☺

[@randywl8925]

I have touched a lathe once since HS shop class in 1975. Machining is so satisfying to watch. You'd be a fantastic shop teacher. No questions need to be asked, because you describe everything in such perfect detail as you are working the parts. Extremely well done video, or in my 1975 verbiage, that's groovy. 😁

[@johnptc]

Quinn........... always a pleasure to watch :) Happy holidays john ptc

[@terminalpsychosis8022]

That is beautiful. The eccentric is the coolest part of these engines. Seeing it turning like that is so saticfying. Looking forward to the valves getting hooked up.

[@haramanggapuja]

I just parked a link to your videos on my FaceBook page and linked it so my friend Piero in Cellatica might be able to catch it and watch. . . . I really enjoy the way you explain this stuff without being stuffy about it. Beautiful, careful work that's way beyond my level of competence and certainly more patient than I have ever been in seven & some decades. . . . Stay well & have fun!

[@thebotformalityknownasdale2564]

Your narration goes a million miles in to learning totally enhancing to the overall enjoyment of the videos thank you so much Dale

[@randynovick7972]

When I saw this video post, I told myself not to look until I could be back on my sofa at home, where I watch all of my favorite machining videos. It took a few days, but the reward in the viewing was worth the patience. I'm so pleased with how well the project is going. Great stuff. Many thanks!

[@PatrickPoet]

As the slitting saw finished the last bit and the vice released I realized that together they were making a mockery of my horror!

[@fdavillar]

“Villains!' I shrieked. Dissemble no more! I admit the deed! Tear up the planks! Here, here! It is the beating of his hideous heart!” Although I'm not from an English culture, I could easily get the reference to The Tell-Tale Heart. I,m telling this only to illustrate the way English language and culture had become so universal in these days.

I am not that good at remembering exactly where Quotes come from ,But I did remember this From Edgar Allan Poe.

[@larryholloway2869]

Love the videos. I learn so much from you. I hold you and mr Pete, this old Tony in the highest regard. You 3 are my shop teachers and I thank you.

Edgar Allen Poe reference did not go unnoticed. Hope you are doing well and had a nice Thanksgiving.

[@AJR2208]

Hi Quinn, Your intro inspired this comment, so, I'm passing on usual complimentary of your project and instead want to comment on your "Commentary Policy" page. I read it recently and I think it's an excellent idea as a Policy. For me, (like you said in your intro) it gave me a deeper understanding of your character. I highly recommend anyone who has not read it, to do so. It points out an attitude for viewers to carry through Any KZbin videos. Well done. Stay safe and well :)

[@rhavrane]

Bonjour Quinn, As steam passionate and collector of model steam boats and machines, but not builder, I dicsover your channel with a great pleasure and interest. I sincerely appreciate your skillness, pedagogy, and converting measurements into metrics. I live in France and have never met a woman (even my beloved wife) showing interest for steam, so imagining one buildng a steam machine... Please go on sharig with us :+) Furthermore, the funny thing and coincidence is that I have paid a specialist to add Stephenson reverse on one of my Stuart D10. Thans to your video, I know now why I have to pay a certain amount... Amicalement, Raphaël

[@toddsheffield4271]

Thank you Blondi, can't wait to see the whole thing working.

[@andersgrassman6583]

I think we will be building these steam engines also in year 2150. They are such dense projects of moments of engineering satisfaction. The excentric and the lapping of the valve ports are my favoutite moments, but even things like nice wooden cylinder clading can make you happy, even though it's not really engineering stuff. Thanks for making these videos and thinking aloud! Who would have thought one could enjoy shared machine time in your sofa!?! This is insanely satisfying devevelopement I had no idea that future would bring me, back some 50 years ago. People like you, really make the internet and affordable lathes real sources of joy. And most importantly - shared moments! It was all a bit too often lonely 50 years ago.

[@wiltothecollector4420]

As always, great video with plenty of detail for this old woodworker that has never machined a piece of metal.

[@mikebaldwin9972]

Mr. Appleton should be Proud, I thank you for your approach to this project...

[@ssboot5663]

NICE BUILD! I'm not a hobby builder....but I about held my breath all the way through the video in suspense , because if I were making that part, I would have been a nervous wreck up untill I got it finished!(afraid of screwing something up) I really enjoy all your machine work videos!

[@davidmelton7268]

Another great video! Really enjoying this series. I can't think of another KZbin channel that is so perfectly packed with education and inspiration. Your positive approach and passion for the craft is clear in every shot. Keep up the great work!

[@KevinWoodsWorkshop]

You may be eccentric but you got there in the end. Great job done and looking forward to it running on steam.

[@WobblycogsUk]

Funny, I've never had the desire to build a model steam engine but watching this series is really changing my mind. I love the calm way to approach the task and teh fact you explain where you made a mistake and why. It makes me feel like I could do it as well (but I've got to buy a lathe and milling machine first, how ever will I cope).

[@AmateurRedneckWorkshop]

Another great job of machining Quinn. Thanks for the video.

[@alwaysbearded1]

Happy Holidays Quinn. I loved the Edger Allen Poe reference.

[@spannerandcode4298]

I was scratching my head at the beginning thinking how are you going to bore the clamp out with it being an oval. Then the slitting saw came out and it all made sense 🤦‍♂️ Another great video 👍

[@FoxMacLeod2501]

Quoth our dauntless star, from Poe? Mine ears, be thy true? Spoke thy not, mere KZbin machinists, prose of hearts beating, knocking from 'neath the floor, of ravens and murders, of nightmares spawned in Rue Morgue. Nay, verily; 'tis not uttered, thus not heard, never before and alas, I fear, never more. Except when it's a Blondihacks joint! Great vi-jay-oh, as always!

[@fepatton]

Totally laughed out loud at the impact driver bit! Great video as always. You're right, that eccentric does look magical!

[@RobytheFlorentine]

It's so relaxing watching your video and listening your calm voice. I think I will go in my garage and start a new project. Thanks for your time and inspiration

[@AdeSwash]

Great work Quin, enjoying the progress!

[@Phil-fj5fe]

Brilliant as always . Really love watching your channel, its so well explained, shown and demonstrated. Kind regards Phil

[@charles1379]

Hi Quinn, thanks for another entertaining and informative video.Your perspective on matters is insightful. As a hint for any onlookers the use of a parting tool to cut the groove in the Hub requires some preparation, not only does the parting tool need to be square with the axis of rotation but importantly the cutting edge of the parting tool needs to be ground square on the tool, otherwise the base of the groove cut into the hub, forming the eccentric, will not be square as it will follow the taper of the tool cutting edge..... Another point which you instinctively carried out but omitted to mention, for the newbies viewing, was to place a cloth over the lathe bed when using sandpaper on the parts. The grit from the emery paper would do untold damage to the lathe parts, if allowed to get to any mating surfaces. Thanks again

[@billbrennan8405]

Very nice job on this video . Have been sick and fell way behind in my build but putting DRO on my Clausing table mill. Thank You BB

[@franknapolitano9144]

Wonderful Out of Phase Eccentrics and the Stevenson's Linkage to make the engine go Ahead and Astern.

[@Flymochairman1]

Quinn, you are only the second person, after my Mechanical Engineering Lecturer at College, to ever say to use the file in the horizontal-to-vertical way to form a radius properly on a cast surface to smooth out a sprue or flashing, up to the end of a piece of square-stock or w.h.y. Thank you. Everyone I've ever said that to, how to file a proper radius on a piece, looks at me like I grew a second head! Thanks for the great video too. Some of those cast parts, especially the eccentric ring, look like they'd snap if you sneezed on some of them! Great stuff. Cheers and Keep Well!

[@teddycrenshaw223]

Very cool watching you build these tiny pieces

[@tazsnoop1044]

It's so good to see someone who knows how to use a file

[@YooProjects]

Very interesting video 👍Thanks. I like your style.

[@tonywilson4713]

Nice fixturing. And a really good safety point and warning on parting off. That should apply to ALL parting off operations. From Australia well done: 👍👍🦘🦘🦘🦘🦘

[@nicmasterdude]

The reverse arc filing makes so much sense! How have I never heard of this?!?!

[@PeterWMeek]

I thought that "hub isn't spinning" was pretty spectacular the first time you showed it.

[@simthespark324]

Ah Blondi thank you I am looking to build a steam engine and literally was just looking for vids on how to do this. Couldn’t find any! Then you posted this 😁 Nice one. Loving the channel 👍

[@joeromanak8797]

I must complement you on your skills, as is the tradition. I’m really enjoying this series. Keep on making us 😊. 😎👍

[@LordPhobos6502]

I've said it before, but it's worth saying again... THANKYOU for putting in metric subtitles ❤ I do not understand imperial screws; I know the sizes won't be exactly the same, but it helps get a sense of scale when I see M3 x 0.5mm thread vs... (whatever a 5-40 is?). It makes a huge difference, and I appreciate the thought and effort 😊

[@Blondihacks]

I’m glad you appreciate it! The threads never map very well, so those are always a “rough equivalent” but the whole idea is to help metric folks have an intuitive feel for the sizes of the components on screen.

[@okbridges]

I'm watching a machining video while taking a camera apart. What could go wrong?

[@henrikstenlund5385]

it usually ends up having some strange extra parts after building it up and closing the covers

@@henrikstenlund5385 That's what we call "cost reduction."

The law of mechanical reproduction: if you take a machine apart and put it together enough times, you will eventually have enough parts for another machine.

Not only engineering but Poe too, what a unexpected combination! 😎

[@johnkinnane547]

G'day Quinn and greetings from Tasmania Australia, you did a great job of that it was interesting to watch you doing the machining on this part I have two of them to do a bit bigger than yours and the inner eccentric has been made with the bore for the crankshaft already moulded in the casting so I'm a bit luckily there. Love your channel and that unique way that you show and explain things which is great thanks for showing how you did this turned out very well kind regards John

[@theamateurmachineshop2150]

Nice work! Some very cool setups and work holding!

[@spdy3926]

Oooooooo the reference to the "Tell Tale Heart" I am surely in love with you Quinn. So fun! Only for the classical at heart.

[@spdy3926]

Oh yes. I am as well ♥ Love the intellect, truly enticing. A lesser man would cower in his lack of confidence...

[@chrisj4570g]

I’ve used parallels on edge to set things in the 4 jaw, but never on the side as you showed. Till now. Nice tip. 👊

[@leewilloughby6214]

It works nicely this way because sometimes when you use them along the opposite axis it can get a little stuck behind the part and hard to wriggle it out without disturbing the setup. They slide out easily when used as Quinn showed.

[@toolbox-gua]

Yes, I get the idea, watching you come up with a solution. Double the joy.

[@jaroslavpolac418]

Opravdu skvělá skvělá práce!!! Je vidět, že jste profesionál👍👍🌼 Rád se od Vás něco přiučím!!🖐️

i love this old tony but I think you just passed him as my fav you tube machinist.

[@alanmuddypaws3865]

Nice! I'm learning so much from this series. Thank you!

[@davidtaylor6124]

A courageous decision, doing the bore before the eccentric it was to go on! I'd never get away with that.

[@Blondihacks]

On the contrary, I did this because it was safer. It’s easier to fit an OD to an ID than the other way around.

[@ironhorse1888]

Excellent job Quinn. Lots of good tips also. Thank you !

Another great job and great video. I really enjoy watching these. I am learning a lot!

[@edhibbard1030]

I'm new to machining and loving all of your content. When you started milling the aluminum fixture, I was thinking it was quite big. Then in a later shot as you held it in your hand I was amazed at how small it really was. I need to pay closer attention on those close ups.

[@Blondihacks]

Scale is hard to judge in KZbin machining videos for sure.

[@woodywood1951]

I relay like the way you do eccentric with the dead center and the small block. Pretty smart! Hey, I just learn something new... Good job! Just because of that, I just subscribe!!! Good video, good explanation. I like it! By the way, merry Christmas!

[@TheTacktishion]

Good Job...! Nice surface finish also.... BTW you have added a number of "special" vocabulary words to the world of hobby machinist. Each time I use the dead blow hammer when putting a piece in the mill vice, in my mind I'm thinking "Tappy Tap Tap" Keep up the good work!!!

[@Vickwick58]

You are about the only machinist on KZbin who correctly pronounces "height." Almost everyone else says "hithe."

[@Blondihacks]

I think that’s a southern US thing. 😁

[@HanstheTraffer]

@@Blondihacks I think it is more of an illiterate thing.

Zen machining break AND a Simpsons reference....most excellent work!
