Re: Resin Casting Question

Gene Green <bierglaeser@...>
 

Al, thanks for your input.
Is the rubber you use available in the small quantities that a duffer
like me would want? What brand or part number?

For someone like myself not engaged in commercial production just
getting a few castings per mold wouldn't be much of a problem.

RE your last sentence: Would consistent shrinkage (perhaps expressed
as a per cent or ratio) mean that if the full sized masters fit
together properly, then the slightly smaller parts would also fit
each other?

Would a large part with a greater volume shrink more (again as a per
cent or ratio) than a thin or small part? What I have in mind here
are those dimples we see on the larger parts of some plastic models.

Could some solid material be embedded in parts of a large volume to
reduce the amount of liquid resin so that there would be less
shrinkage? Would defective castings, flash, scraps and leftovers led
themselves to 'stretching' the liquid resin? Does fresh liquid resin
adhere well to previously cured resin?

Thanks in advance.

Gene - I was away so can only now offer my two cents. Choosing a
rubber is all a matter of trade-offs. As Tom mentioned shrinkage,
tear strength, etc. all must be taken into consideration. I use a
rubber that doesn't shrink and sets up in 16 hours. The downside is
that it gets fewer uses than other, more popular compounds. The best
way to avoid the shrinkage problem is to cast all of the parts in one
master mold, the masters for which have been sized to assemble
properly. - Al

Guys

I need to sound off on this car. It is my opinion, as a modeler of a SE road but one that did not have this car, that this is a good choice. For those modeling the SE here is a car that they can pretty much call their own. It is about time. Check out the owners list, man o man, GA,CG, the original, best NS and the list goes on.

I sure wish that Athearn would indeed add some details to their long ago paid for car and market it head to head with this Kadee car, as someone else suggested. But, for me, this is a great choice and will save me some time in redetailing a bunch of cars the way that I do. Now, if NS would just give me some time off for some modeling.

Well, Ed Hawkins seems to be saying that it is "correct" for about 16 RRs.
The RPCyc article lists quite a few RRs but determining which are correct
for the car's particular version will take some time. I would suggest
finding a copy of the RPCyc and doing your own evaluation...then you could
tell US...or wait until someone else does it.

Re: Kadee's new offset twin hopper

Mike Brock <brockm@...>
 

Ed Hawkins writes about the new Kadee AAR Standard 34 ft hopper:

The model is reasonably accurate for Alton (later to GM&O), ATSF, C&EI,
C&I, CG, CIL, D&H, GA, GM&O, MILW, NC&StL, NS, NYC, RDG, SB, and SLOF
(later to C&EI). All of these cars had vertical angles supporting the
ends, which were flat, and side sills that were level from the bolsters
to the corner posts. As I stated earlier, some cars require some
different door locking mechanisms.
Presumably negating as Ed said earlier a Kadee painted SLSF and Santa Fe car. It is not Kadee's fault, of course, that the RRs seemed to live by a "not invented here" syndrome but to make an AAR Standard 2 bay hopper without the likes of Santa Fe, Frisco, B&O and L&N seems akin to making a Challenger steam loco for all roads except UP and NP or a USRA 2-8-8-2 without the N&W version. I am guessing that the popular PS-1 generated a collector mentality and so might this car but it still seems odd....and a bit disappointing...that the "major" users are missing in action.

Re: Another PFE reefer....

Andy Carlson
 

Actually. I should have said -25 (the -24 is a plywood
car).

The incorrect ends used on the R-40-25 were the same
end as IM used on the R-40-23. The R-40-23 had no thin
top rib, the -25 should have this thin rib which goes
missing on the IM -25. The R-40-23 has a side sill tab
which supports the side sill corner step, this should
be absent on the -25, along with the -23s poling
pocket. R-40-25s are quickly identified by the
corners, this ID suffers in HO scale when the -23
pieces are used. The car really needs a new end. The
sides (essentially unchanged from the -23-except for
the sill tab area)and newly tooled diagonal panel roof
look good to me.

Re: Sunshine mini-kit (was Kadee's new hopper)

Ed or anyone, do you know the answer to the question about
whether the Sunshine mini-kit for the alternate standard car
would be applicable (given what you know about the side sills,
ends and door locks) to the Kadee car? I assume the Kadee is
correctly dimensioned, but I don't know if the castings will then
match it since I think they were matched to the Atlas body.
I am particularly interested in NP and C&O cars for which I have
the mini-kits.

Sherman Hill's Revenge

Mike Brock <brockm@...>
 

From reading the various messages associated with the new Kadee AAR Standard two bay hopper, I'm curious about such modelers as those that do the B&O, L&N, NYC, MP, Sou, T&P and some of the minor roads like the NC&STL and South Buffalo....<G for Bill>.

RRs like the B&O and L&N commonly operated long blocks of hopper cars. Presumably modelers of both RRs have acquired large fleets of both Athearn and Atlas cars. How does one place these new, state of the art cars in blocks with those having ladder rungs so big only John Henry could get his hand around? I was chided during Prototype Rails for running two covered hoppers together...Westvaco...one with Bowser as delivered step rungs, one with scale sized replacements. So, do you just plop them in the blocks of cars?

In my case...heh, heh...I have no such blocks. Sherman Hill's revenge. Hence, an occasional Kadee car will show up but will not upstage another similar hopper car. John Henry worked for N&W or C&O or some such RR. Larry Jackman worked for UP <g>.
