Re: USATC S-160 Consolidation

Vacuum. I melt with a Kerr Electromelt that I retrofitted with a digital PID controller. I have a propane foundry that will melt a lot more, but I restrict it to summer use. I've used it when there was snow on the ground but I'd rather not. Burn out is with a Kerr 6" x 6" x 6" oven and a kiln that i...

Re: USATC S-160 Consolidation

After a couple of previous attempts at using patterns made in 3D printed wax-like castable resin, I've made it through most of the learning curve of learning 3D modeling software, learning to use a 3D printer, and lost wax casting. I had a pretty good collection of lost wax equipment acquired many y...

Re: Steam railroading to return to Alaska!

The most recent status report is posted at http://www.557.alaskarails.org/restore/progress-reports/2019_11/index.html. Another milestone was reached a few days after the November status report cut-off. All 1143 staybolts in the replacement firebox have now been safety welded. On loan from Greatland ...

Re: Cylinder Borning

Down feed on a Bridgeport style mill will let me bore my steam cylinders, but there isn't enough spindle travel to bore the valve cylinders without some manipulation. In an old Live Steam, there was a photo of cylinder being bored on a Bridgeport style milling machine with the head turned horizontal...

Re: Lathe for turning wheels

The bench you put your lathe on will influence the lathe's rigidity. For the price of a bag or two of ready mix and maybe a little rebar or steel mesh you can have a rigid mounting surface with a lot of mass.

Re: Steam railroading to return to Alaska!

We are excited to announce that our 2019 fund raising campaign is being kicked off with a massive $60,000 donor matching challenge (including $5,000 from me). Several high dollar expenditures are in the pipeline and we are ready to contract for the work as soon as funds are available. Information on...

Re: Do wheels have to be cast iron?

In some ways steel is better. It lasts longer and has better traction than cast iron. Cast iron is the traditional material because that was the most practical way to get the spoke or Boxpox shapes. Now we can do the same thing with CNC. Some have fabricated wheels from rings, spokes, and the crank ...

Re: Steam railroading to return to Alaska!

October was another productive month. Parts are being put back together and much progress was made. The latest progress report is at http://www.557.alaskarails.org/restore/progress-reports/2019_10/index.html. Not to limit himself to the preservation of a single locomotive, Project Manager Patrick Du...

Re: Which steam pump would you build?

@Dick_Morris Do you happen to know what issue had the corrected information on the BSCSP? So far I only have up to April 85.
September 85, page 60.

Re: Which steam pump would you build?

Be advised that some errors were corrected on the BSCSP pump a couple of months after the initial article.

Re: Lathe for turning wheels

I've had 6" and 12" Craftsman/Atlas lathes and a 12"x36" Asian (Taiwan?) lathe. The Asian lathe was far heavier and more rigid than the others and a better choice for wheels. A few years ago I did a run of 32 car wheels on the Asian lathe without problems. Note that one way to decrease chatter is to...

Re: Truck history

It's been a while since I looked at it, but my recollection is that White's book on railroad passenger cars (not on the Internet, though) has information on the development of trucks.
