Re: Resin parts
Jon Miller <atsf@...>
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.

Re: Resin parts
Westerfield <westerfield@...>
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

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.

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.

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. Thanks, Mike Brock STMFC Owner

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. Doug Harding www.iowacentralrr.org

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
