Hey everyone! The themes in the comments this time are: 1) Why no pickle? Because it isn’t necessary. It serves no purpose between annealings, and cleaning the plates up at the end took less time than a 10 min pickle would, with no rinsing and drying required. I use pickling when needed, but it isn’t here. 2) “Grrrr this is spinning, not roll forming!” Take a deep breath and remember that the world is a big place with lots of people who have different names for things than you do. Nomenclature is less rigorously standardized in this world than you might think. Nobody’s experience is universal, so keep an open mind. 3) “Why not put the torch right on the lathe?” It takes an immense amount of heat to get the copper to annealing temperature. The hearth is critical to the efficiency of this. Doing it in open air, with the mandrel and chuck there as giant heat sinks would not work unless you had a torch so big that you couldn’t survive standing next to it.

My immediate thought was it looked like spinning, and this is the first time I've seen the process called roll-forming, but I love the fact that this beautiful mongrel of a language we share with the world is living and evolving and often has many names because of the sharing and evolution.

One of the side benefits of my nearly two year obsession with home machine shop YT videos is the names for tools that denizens of different countries use! One of my favorites is the UK and Aussie term “Spanner”. For all of my 61 years in the states, they’ve been either open end wrenches or adjustable wrenches, but it’s all the same “piece of kit” (thanks again UK!). Now I’ve got to go sort through my scraps, excuse me, “bits & bobs”! Ha! Too many folks overthink this stuff!

The one thing with breakers, is they are thermo-magnetic, so they will trip due to overload and also trip due to heat build up. If it trips and you reset it and start machining again, the second trip will be at a lower amperage draw than the first. The third less than the second, etc. At some point, you end up having to let it cool down.

@jlucasound

@@ardemus It is not a "screw up". It is pushing your machine tool to its limit. A tripping breaker sets the safe limit just as well as a fuse. You just don't need to replace the breaker. Think about it. Now, if you replace the fuse with a .22 bullet, well.....That would be screwing up. Sickle has it right. (I capped the "S", sickle, because I was starting the sentence with "sickle". Great idea. I concur.) :-)

Don't let anyone mess with your bandsaw, mine came to me in the eighties, and still runs fine, even "rebuilt several times, new bearings, new blade guides" as age demands. I built my engine a decade ago, but never built a boiler, I believe I will build one, just because yours works so well, thanks for sharing!

I am not a machinist but I find watching it very satisfying. I am a woodworker and I always hear that the incremental measurement differences are like night and day. I watch several machinists on youtube and I am constantly hearing, "this dimension is not critical" or "this dimension does not matter". I think I'm becoming disillusioned. Is it possible to get to Mars with woodworking dimensions? Dan

Brilliant video. Such a lesson in machining planning and preparation. Unfolded like a game of chess. I'll say it again, this is one of the top education channels on KZread. And yes, the yahtsee caused much happiness to break out here.

Hi Quinn. You machine work is really great. Your solutions to challenges are always interesting. As you mention, not every solution will work for everyone. Your humor is really awesome. Best regards.

Quintessential knowlege for the machinist. Great video.!!!

Oh my goodness that final assembly made me unreasonably happy, it is so nice!!!! This is definitely one of my favorite videos of yours!

Your articulation and diction made this video a great listen, also shows you know what your are talking about. You are the Grace Slick of metal working instructionals.

Geez, you're good! Your voiceover instructional content is outstanding!

Stunning, just stunning! Those plates are beautiful. Really enjoying this boiler build series.

I have no idea what you are making, but I enjoyed watching you make things! I find on my lathes I get better results with larger carbide tool holders, but they are larger lathes. My Rockwell 14x40 is a dream to run, if you can get your hands on a 5hp lathe you will find that mandrel can be done in minutes. You impress me with your detailed work and quality. You make beautiful things!

Very nice video. I saw this roll forming before. Its how bells for brass instruments are made. (Trumpets etc).

@AlRoderick

I remember seeing that and I suppose that the brass alloy that they use for that purpose is chosen specifically because it doesn't work harden like pure copper does, because I think I saw them do it all in one operation with no reheating. Maybe a high lead content in the alloy? If so I hope they use a different formulation for the mouthpiece.

It is a real pleasure to watch your videos. Thanks

Hammer forming is faster, Although your fixture allowed multiple operations afterwards and all with greater precision. So, your way is more betterer! :) This was an awesome video, and somewhat mesmerizing. Thankyou!

A good example of setup and planning/prep being 80% of machining. Love the videos.

You are very good at explaining what you are doing and why in a consise way.

I always pickle when silver soldering. It isn’t necessary when forming.

I've hammer formed end caps and the time it took is comparable to this method. However my buck and support plate were just clamped in a vice so it was a bit quicker to get the copper out for annealing. Your method gives a superior finish.

Quinn busting out the quarter round endmill to use as a form tool: “I’m going to do what’s called a pro-gamer move”

Kinda wish you did your center-finding of the device with your coaxial indicator, but only because they are super cool :D This is a fun project, it makes me want to try roll forming!

This is like metal spinning on a lathe. If you turn up the speed a bit, you can actually do it all in 1 operation by loosening the compound rotation and rotating it as you move in (obviously several passes). You can also avoid drilling holes in the work piece by using a disk to clamp it from the front and back. You can look at metal spinning videos to help understand what I mean. It looks more like wood turning with a skateboard wheel shaped roller on a stick.

I made heat exchangers for 20 years. I am glad to have found your channel.

How have I never seen this channel? THis is excellent!

I really enjoyed watching your video. You explain what you are doing and that makes it very interesting. Thanx

Hi Quinn. I have been aggravated by this fuse problem on my Mini-lathe for , I think 20 years. Then I decided I had supported the fuse manufacturer long enough and I installed a circuit breaker instead of the fuse. End of problem. You just need to pick the correct type and rate for your circumstances.

You are indeed "The Mighty Quinn" ! Nicely done.

I have to say this is easily one of my most favourite channels! You produce fantastic videos and instruction!

You taught this old dog a few tricks about copper forming and that I’ve been told is a very difficult task for anyone to achieve.

Well done, very nice job. To answer your question I'd suggest that the actual forming is about equal in time to hammering however there is probably a bit more time invested in the tooling you require for the method you have shown. Its a nice way to do it though judging by your results.

First time I found your videos. I learned a thing or two. So cool. I had to subscribe right away.

Your most elegant part and process yet. You made it look easy. I know it is not. Years ago I made a spinning tool for a CNC lathe. It was a bearing mounted steel wheel about 4 in diameter and 1/2 inch thick with full rounded corners. Hardened and polished it for good part surface finish. Had to spin a bunch of 6 inch aluminum discs much like your part but not quite a 90 degree bend. Tool required several gradual forming passes but no annealing. Made some scrap and noise at first. Ultimately used to stabilize a cone behind a jet at Mach .8.

Really nice work! Thank you for demoing this technique. I've seen it done before, but your step by step breakdown makes this seem much more possible for a newbie to try. Really appreciate your selective use of different levels of precision, depending on the requirement of the feature.

Miniature boiler.. Now you've got my attention.

Looks like someone knows exactly what they are doing 👍 The threaded studs idea was a charm.

_Anything sheet metal with compound curvature is an absolute delight!_ 😃

In case you’ve never seen the channel, The Luminary Shoppe KZread channel does a lot of this in his trade of making and restoring carriage lamps. Very interesting stuff, and all his forms or mandrels are made of wood! Oops! Sorry I used the W word! Take the time to catch a couple of his vids! A true master!

Nice trick with that radiused cutter to turn the edge. Really nice finish.

Loving the zen moments of your voice and machining

You are an excellent teacher!

Very nice job! When I did my Lion Tube Plates I'd reckon 20 to 30 minutes each to hammer form depending upon how many anneals, it goes pretty quick once you get some practice and confidence. Less time making a former. But who's counting, it's a hobby, you try things out, you learn and you enjoy it.

When Annealing, there is is a brief magical window during quenching when copper will throw off the majority of the fire scale, making cleanup much quicker. The trick is letting it cool for a few seconds after removing the heat, but just a few seconds. It's an oddly satisfying yahtzee moment when you get it just right. Gets harder to do as the pieces become thicker as it seems to be a mechanical shudder that breaks of the scale and when a larger surface as it becomes more difficult to have the whole piece at the right temperature. And yes, as other mentioned, pickling (acid bath) is more satisfying way to clean the copper than the mini spinning banshee of death aka a dremel. It also provides a moment for coffee. :)

Great video Quinn. I enjoy your sense of humor and showing the bloopers, too. We all make 'em - or you're not making much, eh?

If you come in from the front, you can make things round without pre-cutting. Like a parting cut through the front of the sheet. That only works as long as you need to go all the way through or can use a parting tool to cut it off.
