Re: Hydro Test

150% is most common. Depending on the service factor some people like to go higher with a new boiler. Mostly you are looking for leaks. A 150% hydro won't reveal firebox sheets and stay bolts that are nearing failure. I have seen two locomotives fire box sheets down to 1/32" in places that passed a ...

Seems like the rear tube sheet shot forward, carrying the tubes and flues with it?
It's super heater tubes blown out of the boiler after a failure at the firebox end. Locomotive was C&O 2-10-4 3020. 1948 near Chillicothe OH I believe.

Re: Coal dust bricks again

The City Coal Yard found blacksmiths favored coal with lots of fines and live steam buyers didn't like fines. They used to screen their coal and bagged a product for both. One of our club members tried a mix using cement as a binder. He had didn't have much success. Poor burning and lots of crud in ...

My concern is with live steam not full size stuff.
SteveM was asking what car load users do with the dust. For most dust is what they want in the end.

Out of curiosity though do coal dust bricks hold some shape as they burn or do they break up?

Re: Illuminating Water Glass?

You can make your own red line water glass by painting a red stripe bordered by white stripes. General illumination directed at the glass makes it easy to see.

Re: grey iron

If it's trucks on a car they hold up fine. I've got a couple cars with 20+ years on them with iron wheels. If it's trucks on a locomotive I'd go steel.

Re: What type of Drill Rod for Axles?

What effect does the out of round drill rod have? I looked up tolerances on drill rod out of curiosity. ALRO lists concentricity within .005".

Re: VERTICAL TURRETT LATHE (CNC)? NO WAY

We have one in our shop about that size that came off a navy tender after WWII. There are only two parts turned on it but both too large to hold horizontally.

Re: Steam space.

It sounds similar to what I've got on a 10" boiler. 1/4 to 1/2 a glass is a nice water level. As the water level gets nearer the top of the glass it'll carry some water over if the engine is working hard.

Re: Help With Painting Using Mask

You can the mask over the grooves without forcing it in. Use an airbrush angled so the paint carries over the gap between the boards (not into it). Go easy with the air brush. Ray Grosser (excellent modeler) letters cars this way and they look sharp. I ran into a similar problem lettering my tender ...
