What's the old phrase? A Quinn with one measurement knows the length, a Quinn with three is never sure. Loving this series... this is a project I've wanted to tackle myself for years but I lack the skills, equipment, time or space. Thanks for letting me live vicariously through you!
The more I watch you work, the more patient I become with fixture creation. I sometimes enjoy the process of fixture design more than their application.
I've touched things that were hot enough to melt my fingerprints flat and shiny. Fortunately I let go before enough heat got deep enough to cause real injury, but the fingertips were still a bit tingly for hours afterwards. Infrared sight would be really handy sometimes.
@@SouseMouse Yeah, common sense would be too. =/ haha I'm so, so sorry man, I legit just couldn't resist. I get it, I'm a mess of scars, from burns to a million other super dumb moves. **super crooked, black-and-blue-nailed thumbs up** =)
The little lathe that could - with a little understanding from her friend 👍 Smarty pants alert! I'd have been tempted to sneak up on the tube bore with a shallow taper which would "displace" the ovality until I got the size right. Your channel? Your glory!
I would like to take a moment to comment on your brilliance, Quinn. Not the machining stuff, but in your studied recognition that the 'boring' jokes only work for Mr. Appleton, whom I am certain is relieved to know that his are the only 'boring' videos on the subject. Carry on.
Blondi, you commented on the colour of the tube after you polished the body, what I think it maybe is a copper coloured protective paint on the pipe, in the uk Copper hot water storage tanks are sprayed with a copper coloured paint to help stop corrosion.
Fun thought, maybe the pipe has a slight longitudinal bend in it that straightens out once you fixture it in the lathe. I think that would explain the variance in length on the surface plate.
Quinn , We have to go over a few things 1A) all the guys on the east coast agree you could make most of the parts for the space program in your garage . 2B) The hold down clamp on the band saw (1/2- 13) ? Is simple brilliance most guy in the shop yell incoming and dive out of the way when the material fly's off the machine 3C) This week I had to make 16 pins for Miss drilled holes in 6061, The holes were drilled .250 I ended up make the pins .256/.258 for a tight fit so the piece could be resurfaced , Thank you for making these Videos, PeteM
Watching this I was reminded of a recent conversation with a former shipmate who went from being an MM2 to being an engineer. He still has a shop of his own, making parks for a local museum's railroad displays. At least now, from watching your videos, I know what some of the tools and processes are so I don't sound like a radioman trying to pass for a machinist's mate ;-) . . . Nice work and informative videos, as always.
Man... Actually I think i understand much better about manual machining from Quinn videos that from six years in university (where it was more of secondary point of focus but nonetheless).
I think the ocean mod is easily the best machining edit I've seen on youtube and I'm pretty sure I've seen thisoldtony use his lathe as a time machine.
I started to post this a new thread, and then found I was 2nd: You cannot imagine how many times I have needed to use a hold-down clamp (16:40) on a cutoff saw without thinking of it. My saw (High School machine shop) has a useless vice and this idea would have been great! Perhaps you taught us this in an older video that I haven't seen, but at least I have learned it now. Thanks a bunch…
I tend to do it while the machine is running though and I don’t want my fingers through something that might get snagged. That’s why I like the pliers.
One of my jobs requires me to machine the ends of SS welded tube, 76mm in diameter with a wall thickness of 1.6mm nominal. It's 305mm long. It has to have a short internal surface machined for an o-ring too. You can imagine what it's like trying to work thin walled stainless with that much sticking out of the chuck. I use two delrin plugs at either end spaced with an aluminium tube as a mandrel, but I have the same problem of runout as welded tube is not exactly round. I've often thought of doing something like this. Love your work. Good job.
As I have only just recently discovered your channel, I am delighted to watch what is my first Blondihacks video as a subscriber. I'm only sorry I hadn't discovered you content sooner. Fantastic stuff! ^_^
I don't know if it's just me or my headphones. Did you switch from ocean sounds to babbling brook? Back in high school we didn't have a fancy machine with such nice noise control. Ways cool!
BH, I would have put it on a belt sander and faced it off instead of the mandrel and all that work. Just keep it perpendicular on the belt, checking with a square. Great series.
Quinn, When dealing with out of round copper, use a pair of smooth jaw pliers such as crescent or knipex and tighten down as you rotate and it'll bring the pipe back to round however because of more decimal points, this plumbing trick may not work for machining. But don't get hung up on perfect copper tube....it's so soft even a slight drop at the supply house will leave dents and dings.
Awesome, as always. Hey, Quinn, Been awhile. Hope you and yours are safe. Thanks to you and your instructional videos, if you will, my wife has graduated from bench top wood working...table saw, drill press, small wood lathe, etc. to mini-lathe brass letter openers and wood handles attached via of threading. Which states, you did a good service, for the good of any city, via the super inter web highway social media...great job on this model steam project,👍😀
Remembering price difference between 6 and 8 inch electronic calipers made from finest Chinesium, this 12 inch beast gives something between heart attack for its price and enormous envy for no reason (because in home improvement anything that couldn't be measured by six inch caliper would be totally fine measured by tape ruler)
Nice work, Quinn 😊. Trying to remember where I saw an internal lathe spider for just such an application. Maybe Kurtis from Cutting Edge Engineering... maybe 🤔. I got a good chuckle when you put that slug in your chuck. I'd be a little weary too! 🤣 Great vid! Cheers!
Wouldn't it be easier to just make a spider/a part with 3~4~6 adjustable threaded rods, which the center would go against? You could then adjust it to run true, and use it for different sizes of tubing? (I use one myself for 600~800mm pipes/tubing so i know it work quite well) 😊
If you get in a pinch and turn something down a bit too small, you can knurl it and literally increase the diameter. Not by a huge amount of course, but easily several thou. That trick also works if you have worn pistons in an overhaul situation and you're broke. You can knurl the pistons and take out enough clearance you won't get piston slap.
Gonna say it again, this channel is woefully under-subscribed. We need more (ideally young, 'cos y'know, investment in future!) people watching this kind of informative and useful content!
I'm really starting to see those little lathes in a completely different light. After watching countless hours of abomb and others I assumed to get any quality work done you needed serious sized equipment which just doesn't fit in most home shops.
I did same operation on a 5” diameter boiler shell on a Peatol/Taig watchmakers lathe with 10 thou clearance from bed. Wore a crash helmet and a car hubcap down my jeans. Successful. Used milk as cutting fluid. Can’t post the pic on here
I enjoy how you use the term trepanning for this procedure - I'm only familiar with the term from skull usage: "a surgical intervention in which a hole is drilled or scraped into the human skull" - to vacate demons or relieve inter cranial pressure. Also enjoyed the ocean sounds, I'm sure anyone undergoing scull scraping would prefer ocean sounds to the ensuing screeching!
Trepanning is used for much larger jobs as well. Parts that's several meters long, and very large diameters. They bore/trepanning the entire core to be left in the middle after finished cut. This save allot of material.
Excellent brain-, lathe- and handiwork as usual! Btw, you are allowed to grind a wrench to fit a specific tight spot. Sacrilegious, I know, but sometimes you have to!
Quinn, can you make a sonic screwdriver? I mean a functional one, maybe with wifi detector-repeater (retractable), an actual screwdriver tip (reversable flat-Philips), flashlight, pen with cup on the back, etc...
Everyone always has suggestions. Mine would be to rotate the fixture till it was in the most optimal place and shim the place that was lowest and bring it into close enough runout. I guess maybe it was close enough already.....
Got half way through, admired the effort but the ends could be made flat sanding on a plate. Having the mandrel can be used for both ends and once made is a great tool ,saves time if ever making more .its a close thing if making one. Not using the de-burrer on the copper, too sticky. Bearing Bronze, Phosphor bronze in the uk has that same spiral patina on the raw stock I've not seen on other materials. . Or maybe the scrap yard sold me bearing bronze as phosphor bronze. Well unless they have a Codys lab ray gun i guess we can spin a coin. Tip extensions for indicators. shellac glued ? like clock pallets. Tube outside , pipe inside Dont quote me. L not M , will the mandrel fit M , with the correct shim everything fits perfectly well into four lines. great work
Hello, I am from Turkey. I have a lathe, very similar to yours, with the same gearbox and the same gears. It hasn't even been a year yet and I did my first threading experience 2 days ago. Although I carefully check everything, I have a problem with threading. The thread thicknesses of the screws I made are not equal. However, the nut moves easily, but when you look from above, you can see that some of the threads are thick and some are thin. If you are interested, I will explain the subject in more detail. First of all, what is your opinion? I know it has nothing to do with your current video, but I thought it might be more likely that my message will be read in your last video.
This is exactly why I am quite satisfied with my worn out Southbend 9". Having a proper back gear is great when you are working near the limits of the machine. With the addition of a VFD I can run it as slow as 16 RPM and still have more than enough torque for anything I can turn.
WOOHOO! Blondihacks time! This build is just something else. It is awesome to see the tiny little boilers haha... I modified a tea kettle and lets say its not that efficient as a boiler and then there is you. You are making the exact opposite of jank :D
I had never heard of trepanning before. So I googled it. "Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb trepan derives from Old French from Medieval Latin trepanum from Greek trúpanon, literally "borer, auger"), is a surgical intervention in which a hole is drilled or scraped into the human skull." I don't think that is what you did here but maybe I am too new to lathe work.
I wonder if the patina/corrosion stuff was some sort of coating to give a protective layer. The surface texture also looks somewhat regularly spaced, so maybe that was intentional to give a bit of texture for a physical interaction. Granted, it still looks uneven in color, so even if the layer was intentional, the thickness didn't matter too much
I'm getting that lathe as well, ocean sound setting is what I need when putting it in the living room.
24:33 easy,if you get 3 different measurements,just trust the one which is matching your expectations best. :)
My method to the max!!! LOL!!!
What's the old phrase? A Quinn with one measurement knows the length, a Quinn with three is never sure.
Loving this series... this is a project I've wanted to tackle myself for years but I lack the skills, equipment, time or space. Thanks for letting me live vicariously through you!
The more I watch you work, the more patient I become with fixture creation. I sometimes enjoy the process of fixture design more than their application.
Building steam engines taught me that sometimes the fixture is 10x as much work as the part, but that’s how it needs to be to do it right.
Yay! It's Blondihacks time!! Oooooooooh fixtures today!
All hail Metalicore the god of machining!
The holy trinity of CZcamsrs from Canada, in decending order, Blondi (the good), AVE (the bad) and ZIPTIES (the ugly) OH CANADA ! Love you guys eh!
The turbine guy first (AgentJayZ)!
6:02 Such a satisfying "ting" from the ring.
that hot or not line brings back so many memories of touching the part, thinking "its not hot" only to realize that i smell burnt bacon
I've touched things that were hot enough to melt my fingerprints flat and shiny. Fortunately I let go before enough heat got deep enough to cause real injury, but the fingertips were still a bit tingly for hours afterwards. Infrared sight would be really handy sometimes.
@@SouseMouse Yeah, common sense would be too.
=/
haha I'm so, so sorry man, I legit just couldn't resist. I get it, I'm a mess of scars, from burns to a million other super dumb moves.
**super crooked, black-and-blue-nailed thumbs up**
=)
Its really fun doing that in welding gauntlets. You don't feel anything at first and then it burns and you let go and it keeps burning for a while.
@@ScumfuckMcDoucheface Turns out that hot glass looks exactly the same as cold glass (once the red goes away).
@@spehropefhany
Same with hot metal, when a welded piece goes from red back to black it is still too hot to touch.
The little lathe that could - with a little understanding from her friend 👍
Smarty pants alert! I'd have been tempted to sneak up on the tube bore with a shallow taper which would "displace" the ovality until I got the size right. Your channel? Your glory!
I would like to take a moment to comment on your brilliance, Quinn. Not the machining stuff, but in your studied recognition that the 'boring' jokes only work for Mr. Appleton, whom I am certain is relieved to know that his are the only 'boring' videos on the subject.
Carry on.
That was a lot of work for something so minor. I'm impressed.
Brilliant as usual.
And lots of Yahtzees!
As is tradition. 😜
Thanks, and Meow to Sprocket.
*sees slug is twice the size of the chuck* Me: “This is gonna be good”
Thank you Blondi!
I couldn’t find a video in your playlist for the “Ocean” mod, perhaps it’s only available to Patrons?!?! Imperial fist shake❤️
Blondi, you commented on the colour of the tube after you polished the body, what I think it maybe is a copper coloured protective paint on the pipe, in the uk Copper hot water storage tanks are sprayed with a copper coloured paint to help stop corrosion.
That mandrel is a thing of beauty. So cool to see such beautiful things emerge from scrap.

Great start on a boiler. Ahlll be Baaak.
Thank you for sharing. Great series.
Hello Quinn,
Really good work tonight... I enjoyed the video. Thank you.
Take care.
Paul,,
Your favorite hemostats are great for clearing aluminum bird nests from the lathe.
I tend to do it while the machine is running though and I don’t want my fingers through something that might get snagged. That’s why I like the pliers.

That was a Great way to do that. I’ll have to remember the way you did that. 👍 Great Video Quinn.

This was more fun
Well done 👍
10:44 Wow, I think that's the first time I've heard the word 'stockpile' used to refer to a pile of stock. It makes perfect sense!
Thank you.
on steel tube boilers for locomotives we tack weld a bar across the inside of the tube
A 25 minute video making a fixture to do 2 minutes worth of facing. Such is life as a machinist.
She does note that the mandrel will show up in the future for other operations.
Good job 👏

insanely beautiful mandrel wow
Hi Quinn awsome lil !! Project . I had similar problem with fuses going pop on my Chinese mini late so I rep!aced it with a MCB dead simple conversion
A belt drive is useful for these situations on small lathes, slips before anything happens to the motor/mechanism
Tanks
We normally at work turns it down a little smaller and make a groove and put a oring in the groove

Seems like there is a great market for "comic machine knob label sets". They could even be traditional .lol
You're going to run a micro-lathe off of the steam plant, on which you will machine a nano boiler, right?
Nice innovative design Quinn, could you have used the spider on it?.
Thanks for sharing.
TAPPY TAP TAP

🇨🇦 Happy May 24 weekend!! Great video as usual. Your hair is getting long and looking nice! 🇨🇦
when you buy one thing and get something a million times better :D
@6:57 OK. There it is. (Yahtzee). Ya, the sacrifices of PWM verses gear reduction. Ugh. You read (red) my mind, Quinn.
This is exactly why I am quite satisfied with my worn out Southbend 9". Having a proper back gear is great when you are working near the limits of the machine. With the addition of a VFD I can run it as slow as 16 RPM and still have more than enough torque for anything I can turn.
WOOHOO! Blondihacks time! This build is just something else. It is awesome to see the tiny little boilers haha... I modified a tea kettle and lets say its not that efficient as a boiler and then there is you. You are making the exact opposite of jank :D
Nice. L pipe instead of M that will be able to handle more pressure.
I had never heard of trepanning before. So I googled it.
"Trepanning, also known as trepanation, trephination, trephining or making a burr hole (the verb trepan derives from Old French from Medieval Latin trepanum from Greek trúpanon, literally "borer, auger"), is a surgical intervention in which a hole is drilled or scraped into the human skull."
I don't think that is what you did here but maybe I am too new to lathe work.
Wow! That was exciting. Copper is scary. Ask me how I know.
Nicely done.
Have you considered doing the exact same thing to the other side of the mandrel so that you could do some dialing in?
I wonder if the patina/corrosion stuff was some sort of coating to give a protective layer. The surface texture also looks somewhat regularly spaced, so maybe that was intentional to give a bit of texture for a physical interaction. Granted, it still looks uneven in color, so even if the layer was intentional, the thickness didn't matter too much
