Metal Casting - Definitions

Like Nigel I would query some of the terminolgy, but what's in a word ? I would also query the costing per casting. I have stuck with greensand molding, with good results, and the same load of sand for over 25 years. Noel.

I have always said "If it works well for you, use it".

Everyone has to find the methods and materials that they are confortable with using, and the methods and materials that make sense to their specific application and uses.

There is no "one-size-fits-all" in hobby metal casting.

The hobby can range from simple open-faced molds, to the most complex lost wax castings you can imagine, or anywhere in between.

I must say that metal casting has been one of the most enjoyable and rewarding things I have ever tried, perhaps because I failed for so long, and then finally got it down pretty good.

Some of it is that you get to play with fire !

My wife tolerates my metal casting hobby, as long as I don't set the house or car on fire.

Did you ever get a full pour in iron for the whole Green Twin Pat?

Not yet.

I have had a "work-a-lanche" ever since covid started.

I really want to cast a green twin full size, which would have a 10" diameter flywheel.

I thought you might have a que of would be builders at your door wanting a set of castings after the article.

Here is one of the white papers I have studied.

The approach is very scientific, with many options and variables considered.

There are many other white papers like this on the Steel Founders Society of America webpage.

I seriously considered starting a casting kit company at one point, but when you get into the logistics of it, it is not practical from many standpoints, lease of which is profit.

People have not shown much interest in the green twin.

One guy did build and publish a bar-stock version of the green twin in Live Steam recently, and it was pretty decent.

What I really want to cast is a Frisco Standard single.

I have not done any IC work, and am itching to learn it.

And you can't get Frisco Standard single iron castings anywhere in the world, unless you make your own.

We have the technology.
