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.

@mattsadventureswithart5764 3 года назад

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.

@tomt9543 3 года назад

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!

You can replace the fuse socket in those mini lathes with a fuse breaker of the same specs. So when you blow it, it's just a button click and you're back to work!

@ardemus 3 года назад

Obviously, blowing the fuse is a 1 time thing... 2 time thing... 3 time thing... won't happen again. No reason to spend the money on a breaker for something that only happens if I screw up. I won't keep screwing up.

@robertoswalt319 3 года назад

I did that on my bench top mill. It provides me with confidence that I won't be dead in the water if I blow a fuse in the middle if the night.

@danielabbey7726 3 года назад

Yes, that's a great idea!

@richardspees841 3 года назад

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 3 года назад

@@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.) :-)

@AlRoderick 3 года назад

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.

@johnyoungquist6540 3 года назад

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.

You just need to pick the correct type and rate for your circumstances.

@GoCreateHobbyMachineShop 3 года назад

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.

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.

@DavidHerscher 3 года назад

@excitedbox5705 2 года назад

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.

Turning Alu the same rule of thumb applies: if it ain't doin what you want, feed it harder.

Nicely done. Hammer forming is probably slightly slower but not much. I use a pickle bath to get rid of the oxide. When you silver solder remember that if you get it too hot you will get tiny bubble holes which are not fun.

@Deathsneeze 2 года назад

I just found your channel, and so far I'm loving every single video of yours I've watched and I've learned quite a bit! As a thank you, one trick I have learned when working with copper is that you can generally use a spring loaded punch a few times to get a part fixtured for brazing. Also, I haven't seen any video of you actually brazing so forgive me if I'm off on this one, but I would strongly recommend picking up an oxy-acetylene torch for doing silver solder brazing, it will greatly reduce the amount of time needed to heat parts and also reduce the total amount of heat you put into a part. It also works out to be a lot cheaper to use O/A or even air/acetylene than a mapp gas torch, mapp starts getting expensive fast with how long you need to run the torch compared to acetylene

Hi Quinn. Thanks for this. I had no idea so much annealing would be needed but the end result looks very good and something to be proud of. BobUK.

Great job. I really liked your roll forming. I learned a lot about copper that I didn’t know. Really cool stuff thanks Quinn

Your closing question (which method is faster) is exactly what I hoped to glean from this demonstration. Maybe Ron Covell can weigh in on that. Great results, though, which would be a lot tougher to get with hammer and buck. Thanks for another informative video!
