Quinn - you did a great job with all the delicate little details required for this job. It definitely requires some tricky fitting for the teeny wood strips, and the bands that hold them. Bravo!
1" = 1/135 Citroën.... Instant increase in Quinn's eccentric nerd cred 😁
My dad is a major Citroën fanatic so I've driven a few of them (mostly DS19). Nothing like lowering the suspension to the lowest setting, going through a restaurant drive through, then raising the car to it's max height when you get to the window and watch the cashier's expression LOL
First time I saw the Citroen cars with height adjustable suspension was in the early eighties, brilliant when towing a trailer or caravan, ref raise up to engage the ball hitch. I'm from the UK, I was working in Texas, USA, in the 2000s', and one guy was interested in where I was from, he mentioned that someone he knows specialised in working on European cars, and his friend said that the reason Citroens' have adjustable suspension was to accommodate the different footpath or side walk heights in different countries, I hadn't the heart to tell him otherwise.
As a jeweller I can tell you: that air dry clay is not what I use :D
Gypsum or plaster of Paris works really good, just heat it up slowly so the moisture can evaporat. The good thing about plaster is that it withstands and conducts the heat to a certain level and allows for a even joint. The air-dry clay just burns up and ruins your joint with its ash. But way more often i use two steel wires, twistet together tightly, and wrap the parts together with them. The twisting counteracts the thermal expansion.
Oh and we use bigger torches :D from tiny needletiped microburnes for soldering close to a set stone up to big oxyacetylene/oxypropane torches for melting and casting we us pretty much everything :)
Oh and before I forget it: I follow you quit some time now and I really like your work and editing style. Keep up the good work! :)
Greetings, Daniel
I was soldering a small tube onto a big tube yesterday, and had indeed seen someone do it with thin steel wire. Tried it myself, and it worked very well indeed!
"That was a normal amount of work..." 😂 This might be my favorite video so far!
Yay! Slaughtered tree chunks!!
Looks absolutely fantastic, Quinn! Love your ability to noodle things out, along with your refusal to edit out mistakes, letting us learn with you. This channel is a gift to the community, full of integrity and humor.
Your patience is your virtue. I enjoyed watching you solve the many problems. You have a great mind. On to the next project........
Quinn: [doesn't say it]
Me, softly: tappytaptap
This video was great. I have worked on large, industrial scale boilers (read: not pretty) throughout my career, and this little guy is by far and away the nicest looking. Love the mahogany and brass!
I'm glad it's not just me that notices solder and solder. 😙 Beautiful result.
Looks great for a normal amount of work in the shop!
Making and using a third hand works well in holding parts. It is a must in the welding industry.
For boiler banding... There were old story about Christmas roasted duck. Guy couldn't get whole duck, so he sew one from legs (got carried away and got six legs), accidentally got it dyed blue with food colouring... And story ended with "And I stuffed orange and some celery sticks inside it... Just because I can". I think it is excellent explanation for just about any twisted life choice.
That's looking really great. An old AC guy showed me when soldering, the molten metal will flow to the heat, so if you have a puddle of solder, move the torch to the other side of the joint and it will suck into the joint in that direction. Look for that on your next try.
02:58 - honestly had to listen to this three times before I realized you weren't saying the Americanized name for a globally popular sport 😂😂😂
Loving going back to your back catalog while I work my way through my MLA-18 kit. Thanks for all the work!
For the clay fixtures: consider getting some potter's clay next time. Anything that says "air dry" will have other stuff in it, which is why it smelled bad and flaked. You want the stuff that's just refined dirt.
Good tip! I was told to use air dry, but that was not great advice.
Even as a hobbyist model builder and cheapskate wannabe sculptor I find air dry clay to be mostly awful.
@@markfergerson2145 Oh, DEFINITELY don't use polymer clays like Sculpey and Fimo. Those are basically plastic and absolutely will not hold up to a torch. They'll probably release really really nasty fumes tool.
@@markfergerson2145 Baking won't drive off volatiles because polymer clay *is* plastic. It'll burn and release really awful stuff, same as any other plastic. You really need just clay here, or something like the special soldering clay that Rio Grande sells.
I laughed way more than I am willing to admit to the opening "Nuts" joke. Also lagging is the death scream of 8 year old online players the world over.
Sure the soldering isn't good, but that just shows how much you improved when you build your next one, be proud of how far you've come not where you used to be.
Hi Quinn. It's called 'learning on the job'. In a way us hobbyists are all serving a never ending apprenticeship. It's part of the fun. We are generally doing things as a one off as well - never been done before. At least now we have you on RUclips! ..... Cheers. BobUK.
Agreed. We figure out how to do it right when we are done.
@@markfergerson2145
I figured out OTOH, but what does ZOMG BTDT mean?
@@markfergerson2145
Thanks, Mark! More learning for this old dog!
"Brass Squeak", probably the least complained about squeak noise. New clamps look great, wooden lagging tops it out.
Great vlog thanks for sharing and best regards from the UK.
John Quinn.
looks great Quinn I like the look.....Just be careful you don't back into the boiler...We don't want you....Lagging behind :D
I don’t know why it’s so satisfying to be one of the first people to watch a video when it’s uploaded.... but it is 😂
If I had more time on my hands I would be the first person to watch these amazing videos 😝
I'm just happy when I click "Like" and see the number jump by 1.
Quinn works with wood, who would have thought? I sat on some mahogany strips once, then found myself lagging behind.
That boiler is now Adorable. I cant wait to see the next one you build :).
You can buy silver solder in ribbon form. I use 1/16 titanium filler rod to hold small pieces in place, just bend up a small pointed finger weighted down by a block of whatever, solder does not stick to it and will tolerate the heat.
Good tips, thank you!
NOW you tell me... some time ago I bought four surprisingly expensive (in the UK) "hobby" brass strips to put banding round an octagonal box. I've just found a 4' length on that well-known auction site for less than the cost of one 12" strip. Kept putting off joining them together, but at least now I don't have to 😊 Win! 👍 Thanks!
I liked the video, as is the tradition. You proved that something that works in the real world can also work in reduced scale and achieve the desired comparable effect. Good job of catching that tiny nut with the point of the scribe. That was just the way I would have done it. 😎👍👀 🌞
Quinn that boiler is a work of art , little tip for you if you solder more of these blocks..News Flash your set up was very good. what you can do is flatten the solder with a hammer place it Under the block( Fluxed) the more weight on the block the better just heat it up and when the block sinks the solder pushes out the the sides your done. wipe with damp cloth and you are a rock star ..
Good tip!
I am really really enjoying this series on the pm research steam engine. Thank you so much for sharing this! I would love to see a bit more of your cat, Sprocket. Best regards from Brasilia, Brazil.
if you lay the wood strips close together cover with thin cloth ,paint with pva and l eave to dry.
you end up with a flexible sheet of lagging that you can trim and cut holes in
Dirty woodworker here, can confirm that this is a viable option. It's how tambors are made for roll-top desks and the like.
Oh, my! All the years I silver soldered tiny stainless instruments and never saw that lovely ceramic fixture plate! So many parts wired together, so much time I might have saved!
This is awesome! I really need to do this on my boiler... I made it a few years ago and its worn out already. It is super inefficient but it works ok enough for running little engines :D Thanks for the much needed help on this :D
Edit: The oddball fraction of a citroen got me laughing- Im from Europe and it didnt help but my dad being a citroen engineer did the math in his head lol
An old timey method for cutting sheet metal is with a vise and cold chisel. Clamp the cut line at the top of the vise jaws then set the chisel so one edge bevel is level with the jaw surface. Angle the chisel some so it's just off 90 degrees to the sheet and tap away. Heck, it will even curl the cut strip so you don't have to... ;-)
Very nice job Quinn, as always.
I like the horizontal banding over the vertical. You get style points if nothing else.
LOL'd on the scriber to catch the nuts. Works for me!
Fiberfrax under the wood will add a greater insulation power.
Very interesting video.
Thank you for posting Blondi.
Looks nice Quinn. Very similar to the wood lagging used on the barrels of British traction engines. These are then covered with sheet metal cladding. The lagging has to come off every 10 years for inspection and is usually replaced after this. I use 1 by 1/2 batten softwood done very like yours lots of fiddly bits for rivets, fittings and cylinder blocks etc. I use bungee cord to keep in all together. The boiler bands are very similar.
Re: dinky silver soldering jobs.
Can you still get the paste made from powdered nickel silver and the flux.
Just paint it on the cleaned surfaces, assemble / lightly clamp and heat as desired. It even works with "semi-stainless" steels with thin sections./ joining dissimilar metals. relative silver content can vary the "degree of difficulty" in such jobs
This is a great series: very educational. Thank you for your efforts, they have brightened up my "involuntary retirement" considerably.
I absolutely love your self deprecating humor! Who doesn’t make mistakes? It makes us feel like it’s us in your shop. I always looked forward to having a lathe and mill in my retirement, but I had to shift gears and do hand wood working instead, but am still enjoying making mistakes, learning and most of all, creating.
Very Nice Quinn, as someone who did lagging on some (slightly) bigger boilers for about 10 years, you did a great job! Cutouts look awesome, all lines up nice! I never actually knew mahogany was used as a lagging material traditionally so I learned something too :D
Also, the rubber band trick works on the real big boilers too haha, we would just use truck straps instead to hold everything together ahaha
Alternate title for this video: "Down The Rabbet Hole" But seriously though it looks great and I admire your perseverance.
You convert a simpe boiler to a piece of art!!! Many BRAVO!!!
Looks fabulous. Well done. 👍😀
I like your sense of humor.
Kinda neat how the 1/16th in comes out cleanly(ish) to 1.6mm.
I love the part where you do precision work where it's not needed. I'm not a machinist, I'm a flooring installer. If I do a lot of apartment work where high skill is not necessary, then how well am I going to do when I'm working in a million dollar home with some difficult to work with flooring and sanding customers?
I don't care who I'm working for. I do the job with the same methods every time. Do it right
or let someone else do it. I can fix what they screwed up and make just as much money in half the time. 👍😁
I love your logic and it's good for subscribers to understand what you said.
Oh! Instantly more beautiful boiler! Kinda makes me wanna build a boiler! >.> And as a jeweler, I was always taught to use cross-action tweezers, locking hemostats, and the ever-useful binding wire! (BTW, if you ever want to get mad, try re-soldering glasses frames!) XD
Well done, Quin...again.
Interesting job Quinn.👍👍
I can't wait till we get to the point where you float your entire house, steampunk style with a home made boiler and pistons to turn props. I bet you make 15 knots.
That's the most troublesome swell foop I've ever seen, but the end result does look amazing!
Lagging? For a minute there Quinn, I... ok, honestly I didn't know what "lagging" was, but WOW amazing job, it looks great! And the jokes were so funny this time that I fell out of my chair a few times... I wish I could give you 2 thumbs up!!!
Looks nice QD.
I love your channel!!!!!!!!! I could never do what you do but I love watching your solutions
Woodworking? What will the neighbors think?
title made me think of fiberglass resin... =D Great Job with the nuts and the rest of the build.
definitely the best series on saturday evening, soon on netflix. keep on boiling !
Very well done.. Patience...Patience...Patience...
That came out great
OH MY GOSH! She used a caliper to scribe a line!!! (well nobody else said it, and I felt obligated! Never mind the fact I do it all the time! Rebels UNITE!)
I once heard Keith Fenner say 'get your best marking out calipers...' and laughed. And that's what I've called my cheap digital calipers ever since :)
Fancy! last time i insulated a boiler (for homebrewing) i just wrapped it in a towel
Last time i was working with sheet metal on the mill I found sticking the sheet down to a sheet of plywood really helped hold it (cutting 0.5mm brass for rondel dagger guards). I used two layers of masking tape and super glue
I didn't see anything in the first tranche of comments, so: jewelers often use something like a Smith LittleTorch, which has an oxyfuel flame about the size of a grain of rice, so it doesn't blow things away anywhere nearly as much. The other thing many do is use a tungsten or titanium solder pick, just a bit of wire sharp on the end with a handle, and a bunch of tiny squares of solder, like 1x1mm. (I get flat solder strip and cut it with scissors.) You point the torch at a solder bit, it balls up, you poke it with the solder pick while molten, it sticks, and then you can place it right on the joint.
Hang on, are we getting this because the steam engine build is lagging? 😁
I have to say an unrelated thank you: etched my first home circuit boards last weekend. I mostly followed your instructions, except I used cheap boards and "dry film" instead of pre-sensitized boards (which meant I could use sodium carbonate - washing soda - as the developer, removing yet another icky chemical, and could also get it cheaper, and be less worried about light since it appears to need some long wave UV - blacklight from university days). Once I realized I needed a reverse-video print in addition to being mirrored 🤦, it all worked awesome. Thanks so much for your great instructions! I can pretty much guarantee I would not have done it yet if I had to buy ferric chloride...
I really love your content and whenever you get to an inevitable confession/realization about cost:benefit analysis you make me cackle aloud, most involuntarily. You offer a delightful vacation from reality while offering countless useful techniques. Onward!
And it works as a great Whiskey Keg!
An eyeroll and a groan from me within the first 3 seconds. Gotta be a new record.
That’s always my goal
Hello Quinn,
I like your approach of making non precision parts using precision methods to allow you to practice your skills… smart move…
Take care.
Paul,,
Very nice workmanship
Thanks for the pointer on the cheese plate - I’ve been looking for one. $125 is very reasonable and will make lasering stuff easier
OMG! That jewelry fixture plate just blew my fuckin mind. I had no idea those existed.
Woodworking with Quinn, Sounds like a new RUclips Channel :)
That looks beautiful. Unfortunately I use up all my hobby time watching other people's hobbies on RUclips.
Usually when lagging is happening it's anything but zen, but this was nice.
Quinn, Great Video ! ! !
For your ongoing educational Delight, My SMALL Jeweler's Torch head uses a drilled Ruby for the orifice, and throws a 3600 degree flame that has a 1/8" blue cone!
My Largest Torch for that "Micro Torch" has a 3/64" orifice, (Though they do actually make "Micro Rose Bud" Torches for "Large WORK" ! ! !
The small one is used to solder "gold/silver chain links".
I have solder 28 gauge gold wire successfully, but That is my smallest work yet.
My Large Tip earned my Several Thousand Dollars in one job setting: 3 groups of 500 each Brass Trombone Valves, manufactured under contract for a large Japanese Trombone manufacturer.

Girls and their toys! Boiler banding and the music played I thought, "looks like a job for Ron Covell!", then I scrolled down to type a positive comment and SAW RON COVELL'S COMMENT! Very funny and weird.
That is plain & simple stunning! The wood looks marvelous, the brass makes it really look more like sculpture than a boiler. Really sweet work!
Looks great! Really smart stuff, and the fixture plate does look like a beauty.
Your lagging turned out grand! An inexpensive workaround to pricey thin silver solder is hammering your silver solder quite thin and sandwiching it along with flux for an excellent bond, clamping achieved with a well placed scriber. You're an inspiration to modelers and machinists!
I don't know anything about lagging, but damn if that didn't turn out looking fantastic. 😮 That mahogany took up the oil really nice. Great video as always!
Quinn, next time try some Linseed oil mix with a tiny bit of turpentine for finishing the wood. I’m a wood boat guy and all my varnish prime ingredients are those two things.
Beautiful job, nice attention to detail. I wish I had the patience to build projects like this, awesome.
Hi Quinn, I am surprised you couldn't find a better selection of strip brass, not counting boiler banding. Hobby Shops usually have K & S Metals displays, lots of choices. Also, on the woodworking side, the RUclipsr Stumpy Nubs recently did a vid on tung oil, worth taking a look. Thanks for your work, Rich
It seems that I was lagging behind as I got to watch this only now. The mill and the lathe can both testify that I was otherwise engaged! Anyways, nice job! I use a mixture of air drying oils to cover woodon knife handles, it also contains tung oil (and various citrusy oils, smells fantastic!)
Nice work Quinn, good attention to detail with your explanation. I never have any questions of your work. Keep up the good work. I love your videos.
Cheers from Connecticut 😉
That looks fantastic. What a great job. Thanks for sharing.
Hi Quinn, I would recommend you finish both sides of the wood strips. if you leave one side unfinished and exposed to heat & humidity you have a very high chance of cracking and making the potatoes strips....
That is a handsome boi.
Now I want all the things lagged.
THANK YOU...for sharing. Now that was a great idea, looks really nice.
yep been on the making something and my boss knows they make it but we need it yesterday. thanks for sharing!!!
nice job . Correct about keeping skills sharp even when it really doesn't matter .
Boy that really turned out looking beautiful. I like the rolling of the brass with a piece of scrap and cardboard. I never thought of that I’m gonna have to try it next time. Thanks again
Looks very nice!
Very nice Quinn! I am really enjoying you building something that I would have loved to have when I was young! Quite excited to see the whole thing doing it's kafuffle.
My, what a pretty boiler you have there!
Love the special conversion of measurement - suitable, since you are the goddess of small hobby machining ;)
For those small parts that aren’t exposed to a very high temp regular soft solder paste works great and requires way les heat. I use this all the time in my engines, only using silver solder when required.
G'day Quinn that was very informative I like the lagging around the boiler, thanks Quinn regards John
“Nut clearance” sounds like something we could use on the internet😀
Wow colour me impressed :D
Its really refreshing to see you work! Proper engineering, and I say that because you use proper procedures on all tasks(No shortcuts). Ive only recently seen your videos, just by browsing, and again really impressed :D Look forward to check more videos out ;D Thanks
