Nice article, Earl! I've been casting parts and "stuff" for a couple
of years myself and I find that everyone has a few "tricks" to share...

One question - Is that a Sargent-Welch 1402 vac pump you're using and
do you really need that much of a pump? I've 8 of them in my labs and
properly plumbed up they can draw a very serious vacuum...

Martin Brechbiel


OK, there it is. I just uploaded a pdf file to the files section
that
gives a pretty good description of how I go about making cast resin
parts. It has a really catchy name "Resin Casting." I hope some
folks will find it useful.


Feed Mills

Donald B. Valentine <riverman_vt@...>
 

Speaking of feed mills in responding to James McDonald's question
brings up another point surrounding them. Prior to the elimination of
the PIT (Process In Transit) rating, and certainly in our steam era,
feed mills in northern New England seemed to receive the bulk of
their grains via Canadian Differential Tariff routings. Much of this
was, probably for that reason, grain bulk loaded into Canadian cars
with Signode or other grain doors, these having beed discussed before
on this list. I'm not just certain of when the changeover from box
cars to covered hoppers occurred for this inbound grain, however, and
wonder if someone can shed some light on that issue. Was grain ever
loaded into covered hoppers such as the ACF 70 Ton car type, for
example? If so, I don't recall seeing any in such use. My first
recollection of grain arriving at feed mills in covered hoppers is of
it coming in PS-2's and that is rapidly getting out of the steam era
in New England.

The other issue here is grain arriving in Canadian cars. It occurs
to me that they could not be reloaded for delivery of the processed
product, i.e. grain in 100 lb. bags, to the final destination. Is
this correct? If so that would require a lot of extra switching at a
good sized feed mill to remove the empty Canadian cars and replace
them with American cars, with a preference for home road cars, for
the final delivery. While a lot of feed mills have disappeared in
this part of the world over the last twenty five years there are
still some large ones left. The H.K. Webster (Blue Seal Feeds) plant
in Richford, VT, for example, is within a stone's throw of the
International Boundary (literally) and seems to have been, and
remain, about the largest such plant in New England. While most of
the processed feed now leaves in tractor trailers I can well recall
the day when finding 25 to 30 cars sitting at that one plant was
nothing. The CPR kept an RS-2 at Richford almost solely to handle the
switching at that plant. Thus this is an industry that could provide
a lot of action on a model railroad. But I'm wondering about the car
mix for the postwar period as I really don't recall any early covered
hopper types.

Food for thought with one's layout planning.

Re: CSOX 5394 question

Donald B. Valentine <riverman_vt@...>
 

Were it not for the car type, apparently, molasses would be a
viable option for what CSOX 5394 was carrying as a lolt of it was
used in feed mills for pelletized feed and even more for the so-
called "sweet" feeds. The pellets are formed by a process of steaming
the ingredients and and pushing them through a small diameter orofice
from which the final product comes out like a string of spagetti and
is then broken up. I'm not quite sure how the "sweet" feed is mixed
but it is still heated in process and the molasses acts as a binder
to hold all ingredients together. Prodcing all this heat and steam
obviously takes more fuel than what it takes to merely heat the mill
in colder weather. Thus I strongly suspect that the CSOX tank car was
carrying exactly what one would first suspect an oil company's tank
car to be carrying. While feed mills in some parts of the nation no
doubt can use gas (LPG, LNG or even gas piped in) as a cheaper source
of fuel, I have yet to see such a feed mill in New England or the
northeast in general.

Take care, Don Valentine

Take care

Re: Rubber brake air hoses: a disappointment.

Paul Lyons
 

Denny and Group,

Denny I was really surprised by your negative comments regarding the HiTech air hoses. Surprised, because after completing a half dozen models, I absolutely love these new HiTech rubber air hoses. I think they are far superior to anything we have had to date. Yes there are a few short comings. I did not realize that they are a bit long until I read your email. So now I am going to have to go back and carefully look at some completed models to see if .050" really makes a visual difference. I?seriously question that it?will make the difference you describe in your email. On the other hand, I agree,?a real short fall is that they cannot be curved to the prototype shape. A bit unforunate, but certainly off set by the pluses.

I am mounting these hoses to the PSC bracket on most models. They look dynamite! The two big pluses of rubber air hoses?are they do not break if "hit" and they do not foul the coupler if the bracket is not set the "perfect" distance from the end and coupler box. The rubber these things are made out of is so flexable, that if the air hose is in a?SLIGHT conflict with the coupler, the coupler will just "push" it out of the way. You have to see it to believe it.

I plan on bringing a couple of models with these hoses and brackets to Cocco Beach next month.

Subject: [STMFC] Rubber brake air hoses: a disappointment.






Continuing a mild obsession of both creating much more accurate
prototypical detailing for the ends of our steam era freight cars, AND
retaining good reliable handling and operating characteristics while
doing so, I have continued my quest for the ideal air brake hose/
mounting that both looks good AND stands up to more than a few moments
of routine handling. The combination of both shape-able accurate
brass air hoses, and related angle cock brackets have seemed so far to
offer the best combination of both. However, despite absolutely
beautiful modeling accuracy, and the very good anchoring offered by
the new angle cock brackets, the projecting brass air hose still
offers a stiff prominent lever arm to snag the unwary, causing the
hose to fracture at its very thinnest and fine points: the hose
connection to the angle cock, or at the thin pipe between the angle
cock and the supporting U bolt bracket. The brass hoses are certainly
more hardy than the plastic hoses (and the plastic hoses are not
easily shape-able), but they are not perfect. Rubber hoses would seem
to be almost ideal, if they could be made with sufficient accurate
detailing, and were shape-able.

Along comes the rubber hoses produced by HiTech Details. I admit I was
dubious that such fine hoses could be produced out of rubber- but they
do indeed appear to be fine, finely detailed, and with minimal effort
mountable in the new PSC angle cock brackets . However, expectations
were dashed when I noted a killer: the rubber brake hoses are the
27" length adopted by the AAR as standard sometime after 1957, NOT the
significantly shorter 22" length common to virtually every single one
of our steam era cars (my 1957 Car Builders Cyc shows 22", while my
1966 shows 27"). Mounting these hoses in proper locations on our cars
will cause them to drag along between the rails, and in my opinion,
also look terrible in the process.

Other downsides: a mounting lug allows the hoses to be mechanically
attached to the car bottom, but the lug is vertical, not angled to the
center as they should be. Also, they are not "shape-able" so that they
can assume the characteristic "curl" typical of any air hose that has
been used more than a few times.

I have contacted the manufacturer to inquire about these things, in
addition to encouraging him/her to consider producing the shorter
hoses, encompassing a generic "curl" in the process.

Brass hoses: In the meantime, I continue to use the brass air hoses.
They do look great, especially shaped and painted, but I have learned
the hard way that they are the very last thing that I install after
the car is otherwise painted, decaled, weathered, and ready to put on
the track. Every single time that I have fractured a hose, it has been
the result of personally handling, unlike the plastic hoses, which
litter the layout just by looking at them!

I pulled out of the drawer an new-old stock paper envelope of HO A-C
rubber air hoses, a remnant of a purchase made c. 1950. Out spilled a
rubber hose made from wire insulation that scaled out to be about 4"
thick, was stiff as a board, and crumbled when picked up!

Presuming a significant interval improvement in rubber technology ,
just how long will these rubber air hoses actually stand up?

Denny,
I'm still using my cuttings from Micro-bulbs or other such wiring. It's
shapeable and sturdy. Don't know about the attachment to the new bracket, but
angle cocks fit ok, you can cut them to length and seeing as they are excess
material, they are FREE.

James, I can probably tell you a lot about the car if you could send
me a scan of the photo. Unfortunately, the ORER entries for many
tank car owners were not very informative, and that's the case with
Cities Service. CSOX 5394 falls into the number series 5200-6999,
all of which were class TM and 80,000 lbs. nominal capacity, which
probably means that they were 8,000 gal. cars. I have photos of a
couple of cars in the series and they're quite different in design,
builder, etc., so it's obvious that Cities Service just lumped a
bunch of dissimilar 8,000 gal. cars into a single series. Further
complication comes from the fact that, in the 1940s, Cities Service
was in the process of renumbering many cars which originally had EORX
reporting marks into the CSOX series, so some or all of the 5200-6999
series cars were probably former EORX cars with different numbers.

"casting" and "hobbicast"

cripete <pjboylanboylan@...>
 

I think, given the recent discussion regarding
resin parts, that it is worth mentioning that the
YAHOO groups: "casting" and "hobbicast"; are
online groups similar to this one. Their 8,000
members are somewhat overlapping, but the diverse
expertise found within them embraces all aspects of
casting and molding items ( with occasional divergence
to chemical etching and other means of producing
artifacts without mechanical cutting in shaping
same).

I do not believe that you will find more helpful
people, that will respond both on and off line, to
the needs of people with questions about any or
all aspects of any process involved in casting
an object.
