Re: The No-Machine-Tools Steam Plant

I tested it to about 100psi, but I usually run it around 30. The safety pops about 40 and drops it down to about 25, which is more loss than I'd like, but that's what I get for using a $7 safety meant for an air compressor. It works though, can't complain too much. That little engine will run happil...

The No-Machine-Tools Steam Plant

I've been building this up over the last few months. I started with a PMR #3 machined kit (my first steam engine) and really enjoyed it. I don't have machine tools, so while I'd like to learn to machine an engine from castings eventually, in the short term, I had to get creative to have a steam plan...

Re: Water treatment for iron boiler?

Sorry to revive an old thread, but one more question. What is the best way to store this boiler? It's impossible to ensure the whole thing is perfectly dry for storage, so I thought maybe filling it completely with distilled water would be the best option (no air = no rust, or very little). It seems...

Re: Water treatment for iron boiler?

Thank you all for the advice! I guess my boiler is steel, not iron (it is quite literally hardware-store "black iron" pipe) so it sounds like distilled water and some kind of treatment is necessary. It's a very small boiler so it's not an issue to use distilled water. Should I just put some vinegar ...

Water treatment for iron boiler?

Hi again, As some may have seen, I recently finished building the Popular Mechanics boiler, which is a combination of a copper water-tube coil and a chunk of black iron pipe as the reservoir/steam dome. All the fittings are brass. I have been using distilled water (local water is extremely hard) wit...

Re: Found 1899 indicator card in a library book

Here are some higher quality scans. I increased the contrast and played with the image a little to try to make the pencil marks more readable. You can click on each image for the full quality version (it was too big to post on the forum). https://i.postimg.cc/v4yHYbGs/1899-Indicator-Card-AULibrary-S...

Re: Making a boiler without a lathe

Well I did it, mostly. I'm not too happy with the hacked-together base, so I may rework that into something more like the traditional sheet metal enclosure eventually, but a friend had this scrap laying around so it works for now. I've got a small leak around the water glass bottom fitting that I've...

Re: Found 1899 indicator card in a library book

At the LALS/IBLS meet in 1975 Gary Kubicek and I demonstrated the Indicator Card concept using a X-Y O'scope, a long linear resistor and a pair of pressure sensors on a 9" gage 2-6-0 of 1870 prototype chasis which was on air. The scope came from the rubble of ITT Gov. Systems plant in Sylmar. The p...

Found 1899 indicator card in a library book

Maybe this isn't really that exciting, but I thought it was pretty cool and figured I'd share. I checked out a book on the steam engine indicator from the university library because of my electronic indicator project which some of you have probably read about. The book is called "Indicator Practice ...

Re: Using a steam indicator

I had actually planned a similar thing, minus the Bluetooth because I am not that brave and this is a stationary engine anyway, not a locomotive. I've had some calculus already so I figured a trapezoidal Reimann sum would be accurate enough for kicks and giggles. I think if I played my cards very ca...

Re: Using a steam indicator

So I checked out a book (which appears to be about 130 years old, funny enough) on steam indicators from the University library. I have been learning quite a lot about how one might use them on a full size engine and what "ideal" looks like, but the book said one thing that made me curious. It said ...

Re: Bucyrus steam crane

You could probably get a general idea of the mechanisms from somewhere like the Cumbres and Toltec that restores old equipment like that. They have a rotary snowplow and a piledriver, I believe they may have a crane as well.
