Oops! Yes this video was released ten hours or so early because I set the wrong value on time when I scheduled it. Oh well, enjoy an early one (or very late, depending where you are)

Also, a friendly reminder that copper boilermaking is different than HVAC work and jewelry making. They seem superficially similar, but many of the tools and techniques are necessarily different. The methods you see me using are traditional for a reason.

Very nice job, Quinn. I'm on 'pins and needles' to see how the pressure test goes!

[ChrisHiblerPinball]

Let’s just keep going….reminded me of Churchill, “when you are going through hell, just keep going”. :-)

Similar to what Nik Blackhurst said in Project Binky episode 13, this object at this point may or may not be a boiler: if it holds pressure, great, it's a boiler. If it doesn't it's an oddly-shaped, very difficult to use colander. Here's hoping for the former!

What has happened? A Blondihacks video during the day in Europe? A really good surprise! 🖖😉

[robertpearson]

Soldering new joints without disturbing older ones would be the terror-inducing part of this project for me. Ironically, I don’t think I could take the pressure. Also, this Canadian smiles a little when you say Zed, don’t ever change.

[MrPBrane]

It's impressive how much better this project is going compared to the vertical boiler, especially regarding the soldering. Seems like the mistakes there were painful at the time, but you actually learned a lot from it.

[EngineerRaisedInKingston]

The drilling and pressurising "your child" analogy had me in bits 😂 amazing progress so far!

[BetweenTheBorders]

Thanks for mentioning the risk of zinc. A lot of blacksmiths and armorers of my era are acutely (perhaps even overly) aware of "Zinc Fume Fever." A lot of this stuff isn't great to breathe in, but if you don't know about zinc, galvanized steel can sneak up on you. PPE and proper safety is everyone's business; thanks for bringing it up.

[Roblecop]

Every one of these videos gets me more and more excited to see the next step! I'm learning so much about steam engines and various manufacturing/fabricating methods from your videos. I do mechanical design for a living and it's SUPER helpful to me to see how machinists/fabricators actually do the work. The less times someone curses my name when reading my drawings/assembly procedures the better.

You can practically hear the chuffing. Thanks for the video.

Quinn, your humor always leaves me in stitches! “Just don’t play it in reverse…”. Beautiful work as always, and thanks for the details on your thoughts about how to ‘mass produce’.

[douglasharley]

a new blondihacks video?... *YAHTZEE!*

[GilgaFrank]

1:28 - thank you for saying "fewer of them" rather than "less of them". That command of grammar is what really brings in the discerning viewers.

[andrewedgecombe]

Gah! Leaving on a emotional cliffhanger! I’m not going to be able to sleep for the rest of the week!

[IstasPumaNevada]

I think the tube expansion Kozo was protecting against, was the tubes lengthening and pushing out of the end plate, then shrinking to pull back in after cooling. Don't know though.

"That is all the time I have for you today"
Quinn, you're positively spoiling us with these long videos recently!

[KimberlyB-xy]

Incredible build Quinn. I can't wait to see this complete. My only regret is I don't live close enough to come see it run for real sometime. And a HUGE thank you. Seeing this build probably saved me from going down a rabbit hole on a casual interest. There is FAR too much time, work and learning to do for something I am only somewhat interested in. However it is still fascinating and still gives me ideas and tips on other projects so very much worth the watch.

[RushCampAndPrep]

I can't be the only person that giggled every time you said "these nuts"

[jeromemiller]

Another GREAT video. You have the silver soldering down pat the way it looks! Thanks for the free instruction!
