Re: grey iron

So one follow up question. I have a bunch of misc iron castings of unknown origin. How can you tell ductile from gray iron with these existing castings, - E.G. do the two materials look different after machining? Is there some kind of scratch test, or spark test, I could do?? OK, two questions :) T...

Re: Whistles

There is an excellent article in Live Steam Magazine on the construction and tuning of steam whistles. I built a four chime one from the article and it sounds pretty nice. It is made using 1 1/2" brass tubing - it's about 10 - 11 inches long.... There is one on the Green Goddess that does that gurgl...

Re: grey iron

would coal or charcoal be best for heating it up? I believe either would do fine. Coal coke would be the best and maybe even too much heat if you blast air through it. Like a blast furnace or blacksmith's hearth. You could get it too hot. Iron will distort with too much heat - but that's pretty hot...

Probably, wood ashes would make a better insulating cover than sand.
I would be afraid of sand - it can melt. Then you'll have a glass coated casting.

Re: grey iron

Fred, If iron cools too fast, especially from molten, it crystallizes and becomes very hard. The guys are saying to heat it up to red heat and let it cool as slowly as you can. That will 'draw' it back down to a softer state. Same as annealing tool steel after quenching it from red heat - draw it ba...

Re: looking for NG wheel castings

Fred, RMI has 5" and 5.5" and they are 1.25" thick. The wheels that are not specified for 1.5" scale are for the NG equipment either 2.5" of 3.75" scale NG. They also have the traditional flange depth (.188") and a .250" flange depth as well. We bought some of the 5" NG steel wheels from them and th...

What would the maximum rim width that these would finish? Greater than one inch wide?

Re: grey iron

McMaster-Carr has both gray iron and ductile iron in billets up to 12" diameter.... It is oversized and is already pickled so there is very little scale. Nice stuff to machine.

Re: Night Running & Lights?

You know that red cab lighting would be good because red does not effect your night vision. Looking back and forth from the cab implements and gauges to the track will make for an amount of night blindness until your eyes adjust. Red lighting eliminates that. Make your cab a 'red light' district...

Re: Engine stand

Yep, Modified one of the HF lifts and it has no problem with the RGS 20. Widened the stance and replaced those little iron wheels with larger ones rated for >250 lbs. Used 3/4 inch angle (flange up) for 'rails'. And Greg is correct; you could not purchase steel to build one for the price at HF. The ...

Re: Need EBT two bay hopper dimensions.

Tristan, You are most correct with your RMI observation.... The arch bar trucks 'look' really great but 'scale' is not what RMI is after but I will reiterate; they look great. Scale - not so sure.... You are going to be turning some heads with your pattern venture for the Vulcan truck casting patter...
