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!
I'm getting that lathe as well, ocean sound setting is what I need when putting it in the living room.
All hail Metalicore the god of machining!
That was a lot of work for something so minor. I'm impressed.
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.
The holy trinity of RUclipsrs from Canada, in decending order, Blondi (the good), AVE (the bad) and ZIPTIES (the ugly) OH CANADA ! Love you guys eh!
Yay! It's Blondihacks time!! Oooooooooh fixtures today!
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.
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.
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❤️
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!
Brilliant as usual.
And lots of Yahtzees!
As is tradition. 😜
Thanks, and Meow to Sprocket.
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.
6:02 Such a satisfying "ting" from the ring.
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).
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
That little lathe is doing just fine it has a good owner...🇬🇧🙂
Whoah! You can use mill t-slot clamps in a bandsaw! That's one of those things I just never thought to do.
Not strictly on-label usage, but it does work. 😁
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 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.
Metallicor, the god of machining.
That mandrel is a thing of beauty. So cool to see such beautiful things emerge from scrap.
this video reminded me just how much turning aluminium sucks so bad, I've not done machining in a few years and it's just flash-back central!
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.
Blondihacks Channel Moto: If at first you don't succeed, label that attempt as a "Test"
Kidding, Love your channel. Cheers
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.
This was more fun
I enjoy observing your problem-solving methods
Very nice work. Especially on these small machines. Its also nice that You show Your mistakes. Its honest.
Hello Quinn,
Really good work tonight... I enjoyed the video. Thank you.
Take care.
Paul,,
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!
That was a Great way to do that. I’ll have to remember the way you did that. 👍 Great Video Quinn.
Nice innovative design Quinn, could you have used the spider on it?.
Thanks for sharing.
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.
A belt drive is useful for these situations on small lathes, slips before anything happens to the motor/mechanism
A very well-rounded video.
Great job Quinn you are truly a mad genius
A 25 minute video making a fixture to do 2 minutes worth of facing. Such is life as a machinist.
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.
Cool series!! Very nice work!!
Certainly a good project.
Thanks for sharing.
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! ^_^
Welcome! 😁
Thanks for the video!
Life is a learning curve!
Hindsight is 20-15!
Great job Quinn, interesting set ups.👍👍
Thank you for sharing. Great series.
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,👍😀
Thanks Quinn
insanely beautiful mandrel wow
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!
We normally at work turns it down a little smaller and make a groove and put a oring in the groove
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!
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
🇨🇦 Happy May 24 weekend!! Great video as usual. Your hair is getting long and looking nice! 🇨🇦
Really nice work Quinn. Ty
You should try getting an exciting bar. Much more interesting than a boring bar. ;P
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.
Great start on a boiler. Ahlll be Baaak.
Best part of a Saturday evening!
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!
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
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...
Hello Quinn,
I love your videos. I watch them all. I have a question, do you think if the mandrel was tapered very slightly, that it would center itself and, possibly forced the copper pipe to become more evenly round? Maybe I'm just stupid. Just a thought. Again thanks for the great videos, You Rock!

wonderful job
Quinn, did you see the ad for hydroseeders? That is an awesome system. They made the right choice advertising with your channel. I am in no way affiliated. That would be a great business.
You're going to run a micro-lathe off of the steam plant, on which you will machine a nano boiler, right?
the blondihacks expandrel™, coming to a store near you
on steel tube boilers for locomotives we tack weld a bar across the inside of the tube
*sees slug is twice the size of the chuck* Me: “This is gonna be good”
I actually bought a dial indicator from Amazon that came with way more tips than I know what to do with.
If I gonna die I’d like a little warning 🤣🤣🤣🤣 best quote of all time.
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.
Another great video,
I could sit and watch you make stuff all day,
An on another note, is there two aluminium rings for sale only Turon Sunday(Well Sunday was the time I watched the clip)
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.
Seems like there is a great market for "comic machine knob label sets". They could even be traditional .lol
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)
Looks awesome!
What great fun Quinn!
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
The return of superchip!
I like it when you say "The part WE made earlier" Aw Shucks I hardly did anything. but obviously my retrospective cheer leading is important
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) 😊
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!
Exhaust pipe expander with shims fabricated for the id of the 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
That mandrel reminds me of Marvin from The Hitch-hikers Guide to the Galaxy
Wow! That was exciting. Copper is scary. Ask me how I know.
Well, Quinn, looks like the video is starting off with a bad aluminum-hair day! :)
Love the video. Have you considered getting a 1hp 3phase motor and vfd? Would give you marginal more power and way better controll
Why stop at 1HP? Is that the maximum that would be sane for such a machine?
@@NiHaoMike64 i suspect that sticking something bigger to that casting would morph it in second hand Colchester in no time, and Quinn's garage is not that big 😄
Bonjour Quinn,
Great job indeed, you create your tools, impressive ! Question, as it will be a static large boiler, Could you imagine a coal fire heat ? To my opinion, the gas is practical but the coal heater is the must when it comes to steam ;+)
Amicalement, Raphaël
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?
And you have two rings to use for Zena, Warrior Princess Cosplay.
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.....
Thank you.
Speaking of making a mess, uhm I mean, preserving material: what happens to all the shavings? As a woordworker, after a bigger project I'll usually have a pretty good pile to get the fire in my stove going, or let my pets sleep on it, or mulch my plants, but with metal? Do they just go in the bin, do you save and recast them into new slugs, or something else?
TIP.
It would be good for you to have a chip hook. Make it from aro 3/16 round steel. For your size application bend the tip end to be 3/4 in at right angle to the shank which would be about 12” long. Bend the handle in a U shape in the long end. The hook overall should be 12” FOR SAFETY
You need time to let go if it starts to get pulled into the work.
Change all dimensions to suite your application.
I feel pliers are dangerous.
The hook comes from my 50 years of automatic screw machine shop ownership.
JIM
Tapered plugs with pressure from the tailstock? I think that would have both forced the copper round, and done away with the run out
A tapered plug would require you to make a tool that follows the taper of the plug to square up the tube you will also need to tighten the tailstock ram as you get to the inside edge. If I didn't have pipe centers big enough to take that pipe, I would make an internal spider. Use carriage bolts and Quinn's bushing and slug in the tailstock idea.
I wonder if you could seal one end with plastic and tape, fill it with water like a cup, and freeze it, to make it perfectly round.
Some interesting measurements there .
Good job 👏
Great project! Where do you find your "scrap" materials, You always have such a great supply!
