Disney Railroads Discussion Board

If I wanted to make an outdoor 7 dwarfs cottage or a mushroom cottage for a garden railroad what is the best way to make the form? Would it be best to make it out of wood and then cover it with a wire screen then cover that with cement and paint it? How do I keep it waterproof to stay out in the su...

Kinda what I thought. And if you have two water glasses and a cooperative Engineer, you can try things like that. The way to know for sure would be to attach a thermometer or thermocouple to the top of the glass, and have a Temperature/Pressure chart handy to see where the boiling point is at your o...

See, that's the problem with Theory, it doesn't always work in Reality - often from unforeseen complications. I'd need to duplicate the same conditions with that little "desktop boiler" and see what it takes to get it to condense and "Sluurp!" up the water column. 5 PSI might be ...

When you're lighting off, there's plain old air at the top of the glass - that'll stay there. Well, it could slowly dissolve into the water, but that would take several hours at least. You don't have that kind of time. When it's hot and you have steam at the top of the glass and then close the top v...

Mowse: It's more likely to happen at the end of the day once you've put the fire out, and there's no more radiant heat off the backhead. You want an impartial judge, drag Byron B. in there if you can get him out of the Shop. Steve, you just said it yourself - when the water is under pressure the boi...

This discussion brings another question to my mind: how does the glass fill with the top valve closed? To be, that's like pinching a straw closed and dip it in the water... it shouldn't fill. It would only fill when the air at the top is free to escape? Heck, I know that one... Because it's not air...

Full justified, with a caveat that the printers manually jigger it where necessary, and the end of a paragraph often can't be. I've seen automatic systems that get it wrong all the time. (And of course, I make up the previous sentence with six spaces between words, and it totally ignores me...) You ...

Wait, did you mean 180 degrees? (360 being a total circle.) Nope. 90 degrees, as in one-quarter of a circle. With this offset, when one crank is inline with its piston (effectively nearly useless), the other crank is fully up (or down) and can deliver maximum torque. If they were at 180, they both ...

Ah yes. That's called "dead center." Yes! And according to physics and research, that shouldn't happen because the cranks are offset by 90 degrees for that reason! :P And why does moving backward helps? But I think I figured it out :wink: Indeed, I had to reference my own writing (http://...
