The Home Machinist!

Beside being exact to the plan, the obvious advantage of CNC is knocking out identical copies of a shape. Learning to use one is the learning curve for us "geezers". Being honest, most of us like to have our hands on the production, too.
There's a good argument and place for both techniques.

What an achievement!

Just to report back to the group. My Mintz whistle works like a dream on my Reading A5a. It sounds like a choir at lower pressures and at 100 psi, she'll scream a bit over the harmony, but still sounds great. It's a really nice steam locomotive voice.

I'd like to know which were coal fired as opposed to oil or propane fired. Somewhat like colleague cp4449, I'd like to know the condition of the boilers today, and if the locos are static displays, under a pile of hay in a barn, or still operated.
Aren't old movies something?

Glad to hear some discussion of the theory. Thanks, guys!

I was recently advised that spacing my rails at 7 3/8" gauge was the best way to avoid issues with track joints and the like. I'd like to hear what other builders of back yard track (in the east) have to say about it.

My Mintz whistle is 9 3/8" length, and about 1 78" diameter

Just received the Mintz whistle in the mail, and I think this is going to do exactly what I want. Great tone, beautiful sound, works well on lung power. This is good.

My understanding is, it was hotter than blazes in Montreal last weekend.

All this advice and discussion is wonderful. I'm certain we are touching a number of steamer needs and questions.

I decided to give the Mintz whistle a try. Seems to have a nice sound and works on less pressure. We shall see!

Lauren Bacall was a live steamer? Never knew that!
