Everybody has to choose the methods and materials that they prefer to use for their engine builds. I am an old guy who prefers old-school style, and so I encourage that style just because I like it. Everyone has to figure out what is right for them, using the materials that are available in...

ie: not welded in on full sized commercial boilers.

Very nice build; I am enjoying this thread. .

On one of her boiler builds, she had some sort of failure. It could have been another video; I will check. Maybe this one: I fully understand how difficult such a task could/can be, which is why I have not attempted to silver solder a copper boiler. The boiler I built years ago was welded...

I have followed along with blondihacks from time to time, and she started building boilers. I think she botched the boiler in this video. I think she has gone on to successfully build copper boilers with high temperature silver solder. More than one of her videos include in the title "Is it...

I am told the 671 Detroit Diesel was one of the most reliable engines every built. My family has been running one in a houseboat for 50 years. They say "you can lose an injector, or even more than one, and the engine will continue to run at reduced power". Ideal for a single-engine boat where...

I am an old-school builder, so no electronics on my diesel. It would work better, no doublt. .

Its back. Just a minor glitch in the matrix I guess. .

An interesting injector video.

I am thinking along the same lines as nerd. I am sure I could build a true diesel with a high pressure injector, but not at some tiny scale. I would not attempt a diesel build with anything less than a 2.5" diameter piston, just so I could get a reasonable size for the injector and pump. The...

I operate my steam engines on compressed air, for demonstration. I have built and operated a boiler in the past, but that too was for demonstration, and it was not a certified boiler, and so not necessarily safe in the long run due to corrosion on the steel shell. Building a boiler that...

Nice detailing on the small parts. Very clean look to them. .

The problem with "The Home Foundry" is that it may be set up like its predecessor "Alloy Avenue", ie: there is a single individual who runs the entire forum. The individual who ran "Alloy Avenue" was highly reclusive, and I only emailed with him once. I was a moderator on Alloy Avenue back in...

It came back before, so I would guess that it will come back again. Some times it takes a while to get things sorted with the hosting company. .

I have known several folks who have transitioned from brass/bronze to gray iron successfully. The burner output for iron and brass/bronze is basically the same. For gray iron, one needs a clay-graphite Morgan "Salamander-Super" crucible, which is ferrous-metal rated, and 2,900 F rated. The...

That is a cool feature. .

There was a glitch over the holidays with the hosting company that got ironed out (that is my understanding of it; I am not affiliated with that site). Perhaps they will get things worked out again. I have added a considerable amount of foundry material here, just so that it will be spread...

Yikes, just when I was starting to feel that I had some sort of casual understanding of it all. . Edit: I have noticed in some industrial applications that you can get unexpected fluid and gas flow, stratification, etc. due to the momentum of the fluid or gas. I have noticed uneven flow inside...

I think much of the old steam engines (cylinders, etc) were cast in gray iron. I am not sure about things like one-piece pistons, crankshafts, connecting rods, etc. They made steel earlier than I thought (according to one source), but I am not sure when it came into normal production for engine...

As others have mentioned, there can be a great deal of difference between a calculated hypothetical maximum temperature and actual operating conditions, where many things can reduce the temperature inside the cylinder. Hypothetical calculations are just that, hypothetical; ie: not real-world...
