Mea culpa. Bill Welch points out that I had an incorrect model photo for door number 622 the "upside down" door. My apologies. Please discard yesterday's and keep today's. Thanks. Steve Hile

Not to mention the UNION TANK CAR UTLX X-1 tank cars!! AAARGH! :-D -- *Tim O'Connor* *Sterling, Massachusetts*

A couple of things are not being accounted for in this discussion. Yes, metal shrinks as it solidifies, as does most things, water excepted. But in the investment casting process, the molds are at

Good Morning, Fellow Stay-at-Homes, I would appreciate some help. I have a carefully arranged document archive system. The following document was so carefully archived almost 20 years ago that I can't

Really nice build, Bill! Elden Gatwood

Those may well be my parts, I intended to sell part of the run to recoup some of my cost, but when Richard heard about it, he bought all I wanted to sell. Dennis Storzek

Nice work, Paul! Elden Gatwood

An example of the casting work I have done - O-scale freight truck with functioning equalisation - and genuine American black walnut bolster. I had expected to find some shrinkage in the axle-boxes

Well, we certainly have agreement here, don't we? Over the years I heard anywhere from "don't worry about it" to 7% shrinkage from pattern to investment cast part, although I dismiss both ends of that

Paul Woods wrote: Sorry, this is nonsense. The entire volume of the metal is shrinking as it solidifies and cools, and nothing in ordinary life can constrain it. The molten column AND the part

Paul, I will disagree with your statement that shrinkage does not occur in the metal casting process. If we assume the mold is filled out with molten brass, and the brass cools down to its phase

Following on on some previously posted material, attached are two formats of a document describing the post WWII boxcar doors produced by Southwest Scale Productions, with photos of both the prototype

Thanks Tim. Nice photo. Chuck Cover Santa Fe, NM

Hi Folks For the benefit of anyone not familiar with the brass investment casting process: I do CAD design work for cast brass model railroad parts, along with other methods (laser, photoetch); the

How many sets do you need, Brian? Mike Schleigh in Grove City, Penna.

I found the same website last week, They only seem to offer 0.110" wheels. Reboxx were all 0.088" IIRC. I really miss Reboxx. -- Dave Parker Swall Meadows, CA

Brian, I don't have any Reboxx wheels in my stash; but I've noticed an ad in the last few issues of RMC for "JB Wheelsets" that says "slightly different name...same great product!" There is a web
