I'm watching this build right after your "little engine" build, and it's so cool watching you teach things that I watched you learn back then - like making sure the bore is well centred on the two halves of the block. It's really neat to directly see the benefit of the experience you gained in that build.
that ocean sounds suspiciously like a babbling brook smdh
i love your content! so inspiring to see a lady machinist; literally goals
You may want to lightly scrape the bores of the bearings to give the oil room. Given the high polish or finish of the bearing bores, it is possible to actually make them so smooth that the oil has nothing ton "hold" it on the bearing surface. I've had that problem in the industrial world.
A thing of beauty. Your dad joke of "bear with me" did not go unnoticed.
I've never seen a machine with the option to cancel out screeching sounds for soothing seaside sounds! I'm going to ask my machine rep. for that kit!
When this little machine is finished you should make a generator to power the lights in your shop. It looks like a fun project. Thanks for sharing your time and talents with the group.
I have a silly idea at the back of my head that won't go away, to make a steam powered web server from a model engine and an old bike dynamo or something. It would only take a handful of watts so it's very possible
@@PKMartin I love this idea. It's such a poetic juxtaposition of two of the most revolutionary technologies in human history - steam and VLSI
@@PKMartin A bicycle dynamo might be a bit small, but a permanent magnet DC golf buggy motor or similar, run through a regulator could very well power a RasPi of some sort, and they could do some basic server work using under 15W.
can water cool the server so that there’s less heat required for the steam
Lets hope this gets to you ahead of the two week window...I made some modifications to the one I built that have proved worthwhile to me. On part #23 upper linkage thread the hole instead of using the pin to hold the #26 upper valve rod. Then thread the upper valve rod to screw into the upper linkage, This gives you a place to fine tune the valve to the ports. I extended the length of #23 and shortened #26 a bit to allow for some depth of thread and enough engagement of the rod to get a fair bit of adjustment. I also added a lock nut to the mix.
On part #14 upper eccentric instead of drilling all the way through from the top I only drilled for the threaded hole and then moved the oil hole to between the brace and clamp rod hole. This allows you to reach through the eccentric with a hex key to adjust the eccentric position without disassembling the eccentric.

I’ve never done any turning, wood or metal but I enjoy your videos immensely. Your level of talent mixed with a little humour is enjoyable. “Tappy tap-tap gets me every time!👍🇨🇦👨🦳
Also, got to love the "Aaaaaaaaaaaaaaaannnnnnd Yahtzeeee!"
@@Beef4Dinner22 Don't forget to chamfer, because that's ......
@@kensherwin4544 What separates us from the animals? (Bear with me, I'm 3 videos in on this channel)
Level of skill*
I learned turning from 1973-1976. Today I am retired and have a small workshop in my basement with everything I see in your workshop. I am very surprised that a woman also lives out her hobby in this way and obviously with a lot of expertise. It's great fun to watch you. Keep it up and I have already left a subscription there. Greetings from Berlin Germany Holger
I think oil channels inside the bearing caps and on top an oiler would have been a nice feature to add.
Nice metal working, love the vids ❤
6:28 No need to apologize! You know more than a pile of us *AND* by documenting your learning process + all these builds we will be able to learn from your mistakes as well.
Yes, it must be so annoying having to try and head off the armchair specialists in the comments. Working with castings is a massive PITA and every time I watch a video about making these small engines I can't help thinking "just toss 90% of the castings and make those parts from stock, it'll be twice as easy." But wouldn't look anywhere near as nice, sadly. But stuff like conrods and slidebars and crossheads...
26:09 it already looks so cool! I was not prepared for how big-heavy-duty-machine it would look, I am very excited to see the final product
You made Main Bearings. I made a cheese sandwich. Same same. Both bought us joy! Love your videos. 🙂🇦🇺👋👍
A good cheese sandwich is not to be underestimated!
Beautiful job on those bearings - That was intensely satisfying. In my opinion, if that was the only reason a person had for buying a lathe, it would be enough.
Your skill level and videos are getting better, even the boring parts were good. When you were contemplating the use of locating pins I immediately thought of where you can get some 1.6 mm pins from. The replacement turbines for dental hand pieces come with a blank bur. I'm kicking myself now for not collecting them when I was in the industry, I must have thrown out hundreds of them.
Those bronze bushings are gorgeous, thank you for going to the trouble of sharing the process with us. Do please give Sprocket whatever she enjoys for us too; she is a good cat.
Seems like a sound choice to add the bearings. I would also be nervous about steel on iron without a pressure lubrication system. Nice visual touch also.
A little project idea: Make a little handwheel for you mill's quill fine feed. Your wrists will be gratefull. Maybe something easily removable.
The ocean sound had me rolling....😂😂😂😂😂😂
Not sure about precision machining and eyeball being in the same sentence but life is short. My motto, ‘if it’s perfect, it’s probably ok.’ Tongue in cheek!
Yay, new Blondihacks! Always a highlight of my Saturdays
Very nicely done. Next time I fire up my melt furnace I'm going to melt some copper then add 10% aluminum to make some aluminum bronze to try.
Another outstanding episode. If you end up in a pinch, and you have a shaft that's just a thou or two or three too small for a bore, you can knurl it and the shaft will "grow". Then you can turn it down just a whisker to hit the proper OD. Not great for parts that rotate, but great for static fits. To save some money on a rebuild, people sometimes knurl the old worn pistons so they won't slap around in the bore. Hopefully.....you never need that trick. You can also use it to change a sliding fit to a light press fit.
I may have squeed a little bit when i saw that this was part 4 of the new engine build! Sunday morning, a brew and a Blondihacks video...can it get much better?
"Bare with me" while making bearings, I heard what you did there!
Most of my steam experience was working on Stanley coffin nosed steam cars. The ultimate E ticket ride! And these guys haul ass if you think they are slow. At any rate the Stanley brothers created the company that would go on to become Eastman Kodak. They did what is called dry plates. The nefhew knew all the secrets and actually built a small bench mounted steam engine for making some of the original X-Ray dry plates. The photo I saw was a bit grainy and black and white. But looking back, I now believe this engine was the one used. According to PM research, they just adopted the design and went with it. The reason he used a steam engine was that motors were just then showing up and the majority of shops were line drive. He couldn’t get a line drive in that area but could get a steam line.
This is my favorite series yet.
I was always confused by steam engine people but I count myself among them now.
They’re a bunch of cranks but they do work well under pressure.😆
@@robertpearson8798 And of course they like things to be hot and steamy!
I've always thought of it in the same way as electromechanical systems. From an outside perspective it starts off as: "Why would someone get into this?" and snap-cuts to a few weeks later where they're a rabid devotee to the Machine God. Getting to see the internals here (or for electromechanical and similar, the channels "Look Mum No Computer" and "Technology Connections" I highly recommend) and/'or the process not only explains it but piques the interest.
Well, I reckon I'll revisit this when my kit arrives, I had to order an engine having watched almost half of it come together. You are doing very fine work, thanks for sharing!
Thank's Quinn for a another interesting video !
Best machining regards from Sweden .
You can "pre-lube" the bushing material prior to machining to get rid of the squeel and to condition the stock. You drop your material into cold oil. Heat up the oil to bubbling point and then leave everything to cool down on it's own. Try it sometime it works like a charm. It only works on any brass or brass mix alloys
Interesting! I have not seen that technique
Very nice work Quinn. A word on the bushings though, make a channel on the OD centre in case it gets turned and the lube hole gets blocked, unless you already have a plan to deal with this. Cheers and sunny days from MB!
Quinn, I'm blown away by how cool those turned out. Beautiful to look at, and mesmerizing to watch you get there. Great teaching and narration, as usual. ("Ocean Sounds!") :)
If you had sprung for the time travel lathe rather than the ocean sounds lathe, you could have gone two weeks ago yourself :D
Stefan lost to the Devil? Unpossible, I say. The devil has tolerances WAY outside the 1 micron Stefan demands.
Hi Quinn, I always enjoy watching you work and your funny comments,
I think you would be super at parties!😉
Yeah, hardware, programming, model engineering, and race cars - all the good stuff. Peppa Pig makes a joke about Daddy Pig's book about concrete... I didn't really get it. Grady at Practical Engineering makes civil engineering very interesting :)
@@davidtaylor6124 Vladimir Putin, is that you??
Out of all the tubers my 4 kidos seem to understand your teaching the best. We laugh, we scream- good times. Thanks so much !!
How has it taken this long for me to find this channel?!?!?!?!?
I’d suggest studs and hex nuts instead of plain bolts, but them I’m British and we like to take half a lifetime making models 😁
Half a lifetime is simply not enough, maybe 7/8 😁
For the cap location try machined hollow dowel pins that the hold-down bolt can pass through.
You do really nice work. Pleasure to watch. Thanks for the video.
Ampco bronze is extremely handy to keep around; it's uses are various. It and it's cousin Nibral (nickel aluminum bronze) are my personal favorites for machinability, weldability, and most importantly, durability. If I'm making parts out of bronze for myself, these are the two types I personally reach for. That being said, in my real job as a CNC machinist/programmer, I just get to deal with whatever the customer specifies.... That can get interesting....
Interesting you say?
Happen to have any standout horror stories in that respect? Do love a good tale of woe.
@@jaxblonk5127 Getting to work (2nd shift at the time) to find that my 1st shift counterpart had just snapped an ~$3,500 12' long cast iron chunk of Durabar because he forgot to unclamp one of the vises before he tried lifting it with the overhead crane.
VERY NICE !! That whole series of operations went near flawless 👍 I love the bronze bearing inserts 😁😁
Excellent - really enjoyed that one :) The bronze bushes are a nice touch and improve the look and function no end. I can't believe they didn't specify them in the instructions. We're not savages. But then, they also supply those awful screws so perhaps *they* are. I don't know how they can supply such nicely done castings and then throw those screws in the box with them.
Not sure why you're questioning the idea of the bushes locating the two halves of the pillow blocks. Seems totally reasonable from here. I guess you could have done the stepped thing like on the little engine but I bet they wouldn't have bothered in production, considering it too expensive.
The only excuse I can think of is that they (secretly) want you to make your own screws, but to make the kit complete they throw in some awful ones to motivate you.
@@MrRedstoner I don't make my own unless I absolutely have to, but I'm more than happy to purchase small hex headed screws. They might even be more easily available here in Aus than in the US, which would be a first for anything other than kangaroos. We use BA down here for model engineering, but small metric can be had from a place in Germany called Knupfer.
@@davidtaylor6124 I'm from the middle of Europe, and happen to have a nice hardware store within walking distance of my house, so that's what I use in my exploits. Most often Philips head because that's what I started with, have a bunch of, and don't really care about looks.
Great viewing video, thank you... :)
great idea by adding the bronze bearings
Everytime you upload videos like this, it makes me smile. I think your sense of humor (dad-jokes) are goofy, funny and makes the meticulous parts more enjoyable.
I have never seen a metal lathe or a mill in real life, but I learn a lot from you and other youtubers. It would be fun to buy and use a small lathe but I have never had a project that requires a lathe. Well, it is that and the cost of the machine, the tools and space to store everything.
Enjoyed this video. Steeled myself for bearing this video to the end; it passed muster beyond the boring bar. Excellent subject organization, diction, and work shots.
Sprockets!!! 😻
You must have grown up in Grandpa’s machine shop. I use a lot of the same techniques, just plain old common sense and a feel for your tools limitations. Jolly good show!
For anyone who thought those castings were un-bearable. Endless puns are a condition I've learned to live with.
Awesome idea to add the bearings.
Much appreciation for taking the time to video all of your work and effort.
You're an eloquent speaker and all your videos are a walk over the ice.
Bringing me along like a monkey in a basket you take step by careful step and illustrate the why behind each progression, all while I'm barely able to peel a banana.
I've learned a lot and have been inspired for much more rudimentary and smaller projects of my own. Seeing the work you do leaves me in awe, and am looking forward to part 5.
Can't wait for the next video, as I couldn't for the totality of the video you shared on this awesome channel.
I'm hypnotized by you and your skills, in my opinion you are the best machinist on YT. Merry me, and we will spend the rest of our lives making chips together.
I was actually hoping for some Rucker-esque babbitt pouring here. 🙂
I like to use FHCS (flat head cap screws) for alinement, on split caps and fixtures . The angle of the screw will shelf line up with the hole in the cap.
Great work. Your honing tool looks just like the tools i used to use on drum brake cylinders.
That’s in fact exactly what it is- a brake cylinder honing kit
2:14 Thank you very much! It’s nice of you to go over these terms for people like me who are uneducated when it comes to machining.
Oh yeah, more of the forbidden coffee grounds. They just look so deliciously/deathly tempting!
And the finish on that bronze was [chef's kiss emoji not found]. Let's just say it's highly satisfying.
As ever it's such a joy to watch you work. And the end results are beautiful. 😍
Your shouldered bearings will locate the caps nicely. Nice job!
Great work. Future engine builders can learn a lot here. Thanks for the video.
Ocean Sounds are okay, but I really lean toward rain falling in the forest. Really brings the zen to your project.
I think (but I'm not certain) that the forest rain setting is on the welder, not the lathe.
Good to see your development on approaching machining of castings, very useful.
I tip: use 3 parallels to create a horizontal face on the casting face to machine. Place 2 parallels on the vice jaws, then the 3rd resting on these, and hold up the cast face to this 3rd parallel. There are no parallels under the part.
Great work and video, and great jokes 🤣.
Thanks for sharing
What a fantastic job you made of the bushes
Nice weekend-warrior project for you: build a power down-feed for that mill. Should be as simple as a high-quality motor of some kind and some controlling electronics. Remove the handle, bolt it to the front, and boom! Unsightly wart of progress!
Very impressive so far.
Loving this build!
So many useful little bits of information, many visualizations of techniques, and some attempt at explaining why. Since watching your videos I have purchased two Micrometers, two Rose Indexs, 1" and 2". The book on building the A3 Switcher, and today a Seivert torch.
Beautiful! I can’t wait to try this in the future.
Nice work. No idea why this is so fun to watch but it is....Thank you.
Ooh, yay, been waiting for more of this series.
So good, loving this build, thank you 🇬🇧
Very cool build. Love learn in each video you do.
Those came out beautiful!!
I love this series so much 😭
Yay! It's Blondihacks time!!
Wow! Awesome job. Can't wait to see more videos.
Thoroughly enjoying this!
I always look forward to these videos coming out, and this one didn’t disappoint. 😊
Aluminium bronze can be deceptively tough, it’s a world apart from common brass! In terms of machining it shares similar traits as 316 stainless steels, it work hardens and can be a real pig for some of the more finicky processes like parting and tapping.
Beautiful!! True art!
I really enjoy these big projects. Almost feels like I'm cheating at some puzzle seeing how you figure out how to follow the drawings, but there's very little chance I'll try this particular kit in the future, so I think I'm ok there 😁
Coming along nicely, bearing blocks look great...enjoyed !
Nice work!
Nicely done Quinn
This is such a cool project.
Beautiful work. And some challenging setups.
Beautiful-! Love the fit of those bearing shells.
Very nice work
Looking forward to the next one!
Sprocket sighting around 2.43!
Excellent projects 👏👏
Great video it came out fantastic!
Excellent video Quinn.👍👍
I would LOVE to build one of these, set up a mini-line shaft, and use it to drive a vintage industrial sewing machine.
Very nice....Thanks for sharing
Outstanding development of a modification.
Thanks Quinn
That is so cool! Your such a wealth of info I've had to start taking notes!
AMAZING !!!!
One of your best videos ever. Thank you.
