Re: Duplex steel

I thought duplex 2205 was much more expensive than traditional steel w/copper flues. What about the weight issue with it. I remember reading that boilers built with 2205 are built with thinner material due to its reduced heat transfer. but this would create a lower amount of weight on the drivers. ...

Re: O S Closing Locomotive Division

Their website hadn't been updated in years, was wondering what was going on with them. That's too bad. They made some beautiful kits.

Re: Live steam Mt Gretna Project

Wow that is awesome. I actually bought a copy of that Live Steam issue hoping that there were more pictures inside. Only one or two poor pictures and no more information. You should build it!

Re: Duplex steel

Hi Hoppercar, I wrote that article. Since that time it's become wildly popular in Australia, with many engines completed to the AMBSC Part 4 specifications regarding the use of 2205 duplex steel. No problems have come up with the material or the design since then, it's been a total success. No one's...

Re: Pre-cut cylinder gaskets now available for Allen cylinders

I should also mention that if you have a 2" bore on your existing American you should purchase the M gaskets not the A gaskets.

Re: Model Steam Pressure Gauges

Harlock, I am thinking the final size would be somewhere between 2.25-3" diameter on such a gauge. It couldn't get much smaller than a 2.25" case or you couldn't fit the bourdon tube in the back side. You are free to go up on the diameter as much as you want so I guess the question would be what is...

Re: Model Steam Pressure Gauges

Regarding the question about 15", a quick survey indicates that they run around 100 PSI resovoir with the pumps they've got, and the brakes will lock up much earlier than that so that full pressure is never applied. So 150 - 200 PSI gauge would work. There's definitely interest in a scale dual gauge...

Re: Model Steam Pressure Gauges

Hi Harlock, The next round of the larger pressure gauges are now in the works both in 300psig and 200psig ranges. As this is a spare time venture not sure exactally when they will be done. Hopefully within a few weeks. We are looking at and giving more thought on the duplex gauge. Do you think 150p...

Re: Model Steam Pressure Gauges

For all these air systems, Id love to see a miniature duplex gauge. But Im sure that would be quite the critter to squeeze together and get working. Yea even the full size Westinghouse test gauges are still a bit big for my 3" scale loco. There are some small duplex gauges made for automotive use b...
