News from the Pacific Region

The North American Live Steamer, Volume 1 Number 4
Gordon Corwin of the Southern California Live Steamers club sent good news that he now has his 1-1/2 inch narrow gauge Shay operating on air.
The entire chassis with drive wheels and engine are considered 95% complete.
After a 10-hour break in test with light oil and graphite, the throttle was cracked open another notch, which brought the speed indicator up to 1725 RPM.
With a gearing ration of 2 to 1 it would take 317 RPM to make 1 mile per hour or 1268 RPM to make 4 miles per hour, which is considerable over track speed of a prototype. However, it is felt that a miniature engine of this type would have to do 4 to 5 miles per hour to be impressive.
Next on his agenda is the boiler, and then we hope to give you a later report on the progress of this very fine engineering accomplishment.
Hex Heads
It's Easy to File Hexes
The North American Live Steamer, Volume 1 Number 6
Many times it is necessary to file hexes on motion pins, bolts, etc. This was always a disagreeable job for me until I developed the method here described, and which took most of the pain out of it. This may not be a new idea, but it is certainly fast and quite accurate.
First, make a safe file from a 6 or 8 inch flat mill file, by grinding the edge teeth off smooth. This smooth edge will protect the flange of the pin, if the pin is to have a flange at the base of the hex head.
We will take a 5-40 motion pin with flange for our example. Turn the "hex head to be" in the lathe to a full 3/16 inch and the required length, say 1/8 inch. Thurn the flange, say 1/32 inch thick and 1/4 inch in diameter. Of course the shank will be 1/8 inch in diameter since it is a 5-40 and whatever the desired length.
With the work still in the three jaw chuck, move jaw Number 1 vertical. With the safe file smooth edge next to the flange, file about five or six strokes, with even pressure. Be sure to keep the file square with the work in both directions. Then move Number 2 jaw straight down, filing the next face, counting the strokes. Then move Number 3 jaw straight up and file face Number 3--and so on around the head. In other words, we are using the three, 120 degree chuck jaws as a dividing head and moving only 60 degrees, six times to get the hex.
At the end of the operation a little truing up, probably, will be necessary. As a guide th ehead can be filed to fit the size socket wrench which will be used on it.
It is not a bad idea to practice on a round lead pencil or a small round piece of wood.
This method certainly paid off in building my Shay engine as there were 27 hex heade dmotion pins with flanges to be made.

- Carl Herrera now owns this engine . He has totally restored it to its original beauty. He spent many hours repiping and repairing worn out parts . The purple paint is still the original paint but most of the black paint is new.

- The Shay really looks great, I remember it from when Francis Moseley owned it, was pleased to see you even have the cable wrapped around the sand dome.
Gordon Corwin Meets
From The Miniature Locomotive, July/August 1953
By C. S. Chovil, Secretary, Southern California Live Steamers
The Gordon Corwin annual picnic and engine meet proved very popular with S.C.L.S.. the attendance was more than in the past years, the day was perfect and the tracks of the SUNKIST LINES in good condition. Many members brought their lunches as invited, came early and stayed until the last boiler was blown down. The roster of locomotives was as follows: Jim Keith's 1 inch scale Hudson; Barny Shrive's 3/4 inch scale N.Y.C. Niagara; Irene Lewis's 1 inch scale six-wheel switcher operated by Bob Harpur; Milton Uhler's 3/4 inch Tom Thumb; John Matthew's 3/4 inch English Shunting engine "Pug"; Burt Petersen's 3/4 inch Northern; Bill wightman's 3/4 inch 2-4-4 tank engine; Andy Wightman's 3/4 inch Mogul and J.D. Hillyard's 3/4 inch Atlantic.
