Hi all,

What does this have to do with small scale live steam?
Honestly, it's not exactly on topic, although there was an O-Gauge layout there
- but
Walt,
The way these things are supposed to work is that the steam in the top
leg is slowly condensing on the cooler metal and glass, and is supplying
water which is slowly going down through the bottom fitting and back to the
boiler.

Ive followed this with interest..becuase Ive had the Plastic plate in Mamods
blow out while running ,very scary[but not real dangerous!] the type of
water glass on the Merlin /Beck locos is easy to make. Body from 3/8 sq
brass . milled channel in center with bolt holes around outside, recess
Du'h. Of course, you're correct about that. It's a function of
pressure.

Would it be possible to use Pyrex microscope slides to make that kind of
sight gauge? The Pyrex should have more than enough heat tolerance and the
lab slides are very uniform in thickness, etc. True that would not eliminate
the meniscus thing, but with a red line behind it, it should not be a

What about the joint between the pipes and block.
Walt and the List:
According to Properties of Saturated Steam data from the 1991 Brooks
Instruments catalog, saturated steam temperatures for various pressures
(psig) will be:

0.0 212.00
20.3259.28

Gary,,
You Knitpicker you--at least he incorporated some good ideas Some
credit for the poor fellow! Thanks for the history.

So Merlin loco works knew how to
do it almost 20 yrs ago!
I wouldn't think I would bestow credit on Tom Cooper aka Mr. Merlin. Most
likely it was
Hi,
To my knowledge, the last loco Tom Cooper marketed in America was based on
the Barclay Locomotive Works Aileen. By coincidence, Mr. Andrew Barclay,
founder of said locoworks in Kilmarnock(sp) has a grandson living in the
states. He visited me at The Depot today Andy and I have been friends
Steve,
My fuzzy logic (Balvenie fortified) seems to think there is some sort of
temperature gradient, otherwise all the water would flash to steam unless the
increasing vapor pressure keeps the water from shifting phase, requiring
greater heat input per unit to increase the temp to make more
Walt,
I believe that your statement the increasing vapor pressure keeps the water
from shifting phase, requiring greater heat input per unit to increase the
temp to make more steam is correct. As the boiler continues to be fired the
temperature and pressure both rise until the safety blows.
Thanks Walt,
Very interesting-I like the description of your Cooper Aileen. My Hunslet
cost $500 new, it is powerful too--a 2-6-2, and long running. Has
required some repairs--my fault! --I like the description of your Cooper
Aileen.

Hallo Michael,
Really enjoyed the pics, like assembling an Aster or O.S--A-Hem!!
