Re: types of coal

This past winter my live steam buddy and I were fooling around with coal bricketts that we made from different proportions of bituminous coal and anthracite. We used an old lead pot and steel rod as a mortar and pestal to pulverize the coal into fine sand like grains and dust, then we mixed various ...

Re: Building a model of a GG1

Yes, the copper strips are bus bars. The engine has 12 motors and I concluded that bus bars would be the best way to connect them all (I hope).

Re: Phoson 0 brazing rod

I did some further research and found that Sil-Fos 15 is not recommended if exposed to sulfur or steam as would be the case in a copper boiler, and that phosphor/copper brazing alloys (Phoson) tend to make brittle joints. So far that's all I can find, but it's enough to resurrect my concern for how ...

Re: Phoson 0 brazing rod

Ok guys, you just opened an old wound...does the sulfur in coal really affect Sil-Fos and Phoson solder, I hear so many different opinions that I don't know what to believe. I've been running my LE Atlantic on charcoal (real wood charcoal that I make myself) because I suspected that the LE boiler wa...

Phoson 0 brazing rod

I have never used this type of brazing rod, but I understand that if used on clean copper, brazing is done without flux. My question is how is oxidation of the base metal prevented when applying heat? Is it through flame manipulation, oxidizing or reducing, or some other technique? Thanks, John

Re: Release agent question

I'm not familiar with the Furan process, can you explain it Harold...reason being, I still use shellac to finish my patterns.

Re: Release agent question

I still make my patters the old fashion way, out of wood. I'm amazed at the power of the 3 D printer, but I just don't want to make the investment in time and money to learn CAD and purchase the all equipment, besides, this is my hobby, if I was doing it as a business it would be a different story. ...
