I agree with both Al and Earl. As I said these would not be for production or even 100's of items. It's a cheap solution for the modeler who wants to do just a few items and is tired of bubbles in the work. 60 bucks is cheap. Even cheaper is buy a pressure tank (HF sells them cheap also) and use your compressor to make pressure castings. Tom Madden showed me how to do this and it works extremely well. No high pressure, about 40 psi works.

I second Earl's advice. That's precisely the pump that I use. Even so, contaminants can readily clog even those. We bought a second pump because one was always failing. We solved the problwm by using a tank filled with oil with a standpipe through which the air was pumped, removing possible impurities before thay reached the pump. - Al Westerfield

That would be Harbor Freight, importer of cheap Chinese stuff. The
pumps mentioned are intended for HVAC use, typically to pump down AC
systems prior to loading with working fluid or gas. They don't take
well to contamination and you will have a lot of contaminant coming
out of the resin at those vacuum levels. A far better pump for
casting is a Welch/Sargent Douseal pump - you may remember them from
your old high school physics or chemistry class. New they cost
between $2000 and $3000, but you can readily find used ones for about
$300. They are easy to rebuild and with no plastic or rubber seals in
the vacuum path, they tolerate contaminants very well. They are
continuous duty pumps, built from BIG hunks of steel (mine weighs in
at about 100 lbs), and will run for hours without problems.

I used RTV silicone caulk to attach a 6" PVC pipe union to some 1/2"
aluminum plate and to form a seal to some 1" thick acrylic sheet for a
see through top. A needle valve in the top allows me to control
vacuum level during resin degassing. If anyone wants details on how
to set up a resin vacuum casting system, contact me off line.

Pappa Bens is moving. They closed about 6-8 months ago but should be open again in a week or two. I have no idea if the stock will be as extensive or not. The Houston Roundhouse had nearly everything I ever needed, so I miss Wayne. G&G is the scratchbuilder's paradise.

Guys -

Thanks for the nice comments!

Richard and Tony - We do not have a real hobby shop here (San Antonio,
9th largest city in U.S.), two recently closed in Houston (where I have
been buying books), and the good one in Austin is supposedly closing in
January! Looks like I will have to resort to ordering books on-line!
Was hoping to pick up the reefer book and the latest SP freight car
book at Papa Ben's in Houston last week, but it is not open at the new
location.

The photos are really wonderful. I would love to have wet prints of
all of them! The trackwork was amazing! It would be interesting to
have seen those times, but I'll bet there was some hard work done in
bad conditions at some of those buildings.

That's a quite good vacuum, Jon, far beyond what's needed for resin casting. And those microns? They are micrometers of mercury, so convert them into inches and you have it. It's less than one 10,000th.

For those who might wish to make minor parts of resin. for their steam era freight cars, HF now stocks vacuum pumps in two sizes. I doubt these will do any work beyond small parts because price equals quality.

How many do you need and are you capable of laying out the artwork?

There are several custom printers who could do it - you'd need the data

of course to do the masters. Contact me directly if interested in

pursuing this approach. (I am NOT soliciting work - I've just done

artwork for a commercial company and had decals done privately).

Need plain A end, Storzek, CN 1917 Boxcar Kit

carman_ron <rpsmith@...>
 

Hello All,

I just picked up a Dennis Storzek, Canadian National 1917 Boxcar Kit.
Missing in the Kit is the Plain (No lumber Doors) "A" End. The kit
instructions says it came with 2 "A" ends, one with Lumber Doos, one
without. The Instructions say "when the end sheathing needed renewal,
the doors in the A end were omitted." As I plan to model this car for
the late 50s, to Model the car right, I need the plain "A" end.
Anybody out there have this kit (Built or unbuilt) and not need the
plain "A" End?

Re: Digest Number 5515

Re: Cement Container Gondolas.

The DL&W, D&H, and NYC had purpose-built cement gons. These carried five of
the containers. Many years ago Red Ball had a kit for these cars.

In addition the LV and DL&W had regular gondolas of various sizes converted
to this service(all the LV cars were); the cars carried five or six
containers, depending on car capacity. I don't think, someone out there can confirm,
that either D&H or NYC had other than the purpose built cement container cars.
they all were pretty much out of service by the early '60's, here in the
east, when the big tractor trailer bulk cement carriers ate the railroads lunch.

I have a number of these cars in operation, along with many "regular" cement
hoppers.

ADMIN: Photos in the STMFC archive

Mike Brock <brockm@...>
 

There seems to be some confusion with regard to photos uploaded into the STMFC archives.

1. Photos should only be placed in the Photo area.

2. Photos that ARE uploaded must be approved by STMFC management...uh...me or my assistant, Jeff Aley...to ensure that there is no copyright violation. If you wish to upload a photo, go through the Yahoo procedure and you will receive an inquiry regarding ownership of the photo.

3. Photos found in the files area stand the risk of being removed during periodical checks.

Re: Meat Packers

Steve some great photos. The one of the ex Lackawanna stockcars was not fully loaded, can only see a partial image. Could you
reload that photo? You might also want to join the Bullshippers yahoo group,
http://groups.yahoo.com/group/Railway_Bull_Shippers_Group/ where discussion is focused "This group collects and shares information
about railroad livestock and meat transportation and the rolling stock, facilities and operations which supported it. This group
covers any railroad in North America, plus the meat packing business."

I would also suggest, as all your files are photos ie jpgs, that you reload your photos in the group photo section. You used all
the available space in the file section, while the group photo section has 100gb's available. Yahoo recently changed the photos
section, allow much more space and permitting original size images to be viewed (ie no more reducing of image sizes).

I, for one, am very interested if what you are posting.

I bought a couple of sets from Short Line Products a few years ago. Their address is P.O. Box 267, Pequannock, NJ 07440.

The sets provide enough decals for 6 cannisters for the DW&L, the LV, the D&H, and the NYC. Hope they are still available.

Meat Packers

S hed <shed999@...>
 

I've created a new folder called "US Meat Packers" and put some of my Armour, Morris, and Wilson stuff in there. And most of my stuff concerns Oklahoma City that I have collected from various sources.

If someone has information about Cudahy, Switft, Oscar Meyer, or any other meat packer than that would be a great folder to put it in.

Re: WWII 50 foot Steel Box

devansprr
 

Wow!

Many thanks to all for the good input. Found some of the Proto's on
ebay, interesting that the cars with the WWII heralds were the rarest
(and none of the NYC cars in original paint).

For cars out of production, e-bay seems a good indicator of accuracy -
the less frquently you see them, the more accurate they are. I would
think manufacturers and delears could take that lesson learned as a
key marketing data point. Inaccurate cars will end up in clearence sales!

Ted's CofG car may make a good early Box car resin attempt - although
I plan on learning about resin building with a few F&C gons first -
smaller WWII gons seem to be almost non-existant in plastic, even
though there were a LOT of them. With F&C 2 for 1 deals at Timonium,
some of them run $10 to $15 each - not a disaster if the first few
turn out lousy (and hopefully only a few!)

Appreciate the heads up on the N&W resin - might be a good kit if I
get good at Resin cars - it is certainly a unique looking car.

I checked rib side cars - there 50' is just about to be released -
will keep an eye out for them - probably one of the larger WWII 50'
steel fleets. There appear to be at least 10 Proto's that are era
accurate (with length, height, doors and heralds as the only
criteria), but many were from fleets of 25-100 cars - would be quite
rare when there were 27,000+ PRR X29's on the rails. (I'll skip the
roster "balance" topic for now ;-)

The RPI site has good info on paint schemes, but not much on how close
each Proto car was to the prototype - candidates with WWII heralds
include GTW, Southern, LV, Erie (I see another thread on the accuracy
of these), SLSW, P&LE, SP, NYC, KCS and UP. Do any of these jump out
at anyone as way off, or a good match? Hard to justify more than a few
- 50' steel boxes were only 3.5% of the WWII boxcar fleet.

Thanks to all,
Dave Evans
