Pre-orders, pro or con.

lnnrr <lnnrr@...>
 

Folks, it appears that the concept of pre-ordering models months
before they are manufactured is becoming standard in some areas of
our hobby. I understand that this is a safety feature for the
manufacturers, that they can estimate the market and place the
production run at a 100% sale. Little risk of over-production.
It also says they have given up control of the manufacturing process
and so must control the market.
I, for one, am giving notice that I will no longer buy into the
pre-order cycle. When I buy a product sight unseen, I see myself
making a bet that the product will meet my hoped for quality
standards. By the time I know, it is too late. Pitch it or
ebay it, either way I lose.
If the maker has no faith in the marketability of the product and
fears it will lay unsold on the shelf, then I have no faith in
his product either. I will not make that bet again.
Yes, I will miss out on some products that I might otherwise find
desirable. But I see that as offset by having wasted no money
on disappointments.
I alone will change no makers marketing. But as more of us lose
faith in this pre-order system, those who have control of their
production will stock their shelves and prosper when we buy those
products. A critical review will mean something because we will be
aware of what we are buying.
A review that appears after a model is ordered and delivered is worthless. No longer timely. I hold hope that we as consumers
can help the makers who stock shelves have faith in their
products and in us as consumers. As for the others, perhaps
empty shelves are a portend of their future wealth.
Are there others who share feeling I have expressed here?
If so, please do not risk jail by mentioning or hinting at any
one manufacturer. The cookies there, I hear, are left over from
a wrecked boxcar still laying on a river bank somewhere.

Thanks Richard,

I recall Jon's really well done clinic at Cocoa Beach two years ago regarding the kit. That was my first visit to Cocoa Beach and I'm afraid I absorbed more about the kit and assembly rather than thinking about potential prototypes - I wouldn't have made the association. I'm glad to have the opportunity to try one of them - it's a really different looking tank car with the radial courses, and I think it would go well with the environs of the coke plant. I'll have to hunt up something for the lettering when I get back. Maybe some really heavy weathering...

Re: CBQ GS Gon

Charles Hostetler <cesicjh@...>
 

Looks a lot like the CB&Q GS gon that Sunshine has/had available.
As well as 2000 composite GA's, the Burlington had six classes of composite GS gondolas totalling about 7500 cars, built between
1922 and 1938. They were variously rebuilt and renumbered, some being converted to GT's with solid bottoms. By 1951, when the
photo was taken, there were about 6500 GS's left (2100 GS-5/5X and 4350 GS-7 / GS-8). These three classes were very similar, the
GS-8 having a power hand brake and AAR design trucks.

Thanks Tom and Rupert, I shall investigate the Sunshine offering when I get back home.

Re: bending brass grab irons

Michael Watnoski
 

Hi Rob,

I always bend my own grab irons. It seems that the commercial never match exactly. Many of them use too heavy wire or a material that is too hard to clip without chipping my good wire cutters. Also drop grabs have the wrong dimensions or wide radius bends.

I use a pair of needle nose pliers with a piece of tape on the inside of the jaws. Just set the wire against the tape and roll the jaws on a hard surface for a sharp bend. bend with fingers for a slightly larger radius.

You have found the main problem with Detail Associates wire. It develops a temper in the wire making process. Bending it adds work hardening which makes it brittle. It can be annealed by heating it slightly with a butane lighter at the bend point. Unfortunately, there is very little control of the amount of softening. You also don't want to soften the whole grab as it won't hold its shape when handling.

My suggestion is to skip the DA brass wire and use the Tichy phosphor bronze wire. This has a consistent hardness that will not change if heated. It can be bent multiple times without cracking. It holds a straight line well and bends easily. The springiness is handy for making electrical pick ups.

Hi Jim,

Avery makes self adhesive white and transparent labels in various sizes designed to be run through laser or inkjet printers. I use #8660 clear inkjet labels for Christmas letter addressing, and have never had a problem with jams in the printer. I would guess their labels are typically .002 - .004" in thickness.

Re: guitar strings

MDelvec952
 

As a musician I've used many retired guitar strings on models, .008" mostly on standard grab irons since they are much tougher than brass of the same thickness. E Strings (smallest on most guitars) come in .008, .009, .010, 011 and .012 to fill most grab iron needs, and thicker on B and G strings for brake pipe and other grabs and pipes. Guitar strings stay straight and generally don't stay sagged with most handling.

Some warnings: Short lengths do not bend easily, so use pliers. Guitars strings are steel, so they can rust if conditions are right for it. Certain sections of used strings may have matter (sweat, finger grease, oxidation) on them that may not take paint, so clean them before bending and cutting. Bronze strings have steel cores, as do the wrapped or wound strings. The best long-term fastening in drilled holes I've found is with epoxy, and it's best to drill all the way through so the guitar string can protrude and the epoxy can form a rivethead. Some of my models are more than 20 years old and I've never lost a grab iron in epoxy, and I have with ACC. Most importantly, guitar strings make deep holes in your fingertips without warning. Those on blood thinners or prone to infection should use something else.

If it's ordinary brass, yes, softening it will work. Our brass
wire is cold drawn, consuming most of its capacity for further
deformation (which is why it breaks upon your bending it). Softening
fixes that. But it will also give you ladder rungs that are easily

Another alternative to brass wire would be phospher bronze.  This wire bends very well and makes great grab irons.  You can find some at: http://www.tichytraingroup.com as well as other sources.  Jim Barnes

Re: tank car placards for models

Jim Betz
 

Tony,

===> THANKS !!! <===

As you know I model "the transition era" for about 95% or more
of what I do. The timing of your post and blog entries are 'spot on'
for my personal needs because I am in the process of adding "depth"
to my roster of tank car models. Both in terms of the number of cars
but also in terms of "adding details" (including placards).

So even in the transition era tank cars that required placarding
were, more or less and mostly more, in captive service ... in that
they tended to be hauled either loaded (or empty) over and over
for the same 'family' of products

===> correct?

So if you have some industries on your layout that are actually
using tank cars - you would want to have cars that have both the
loaded and unloaded placards ... and you would want to 'cycle'
the cars back and forth during your op sessions. Sheesh - one
more detail to add to the set up (aka "reset") for the layout! *G*

The placard you picked up at WinteRail was "produced by the SLSF".
Was that 'the practice' for placards in the steam era? I'm asking
"were the placards in the steam era usually printed by/for the RRs
and therefore would normally have a logo on them?".
I would guess that other than cars that are in "company service"
(such as diesel fuel for the RR itself) would not necessarily have
placards on them that are the same as the car. They might or might
not depending upon where the car had travelled recently.

Has anyone ever seen any kind of "post it note material" for
consumer use that can be run thru a printer? I would have to have
some kind of peel off covering for the sticky part. But would be
ideal for model use since you could even change out the placards

Re: bending brass grab irons

Details associates packaged a lot of their brass wire about 20 years ago which
were from a bad batch. Wire from these batches would break when brought to any
near a right angle. Since the DA packaging seems unchanged over these years,
swap meet purchased DA wire may very well be a relic from these poorly drawn
wires of the past. Throw away any of these bad wires, as they are useless for
our needs.

So the better choices seem to be either .01" brass or .008 music wire (I

I think I'll give the music wire a try next.

Rob
Or try .008 brass from a different source. Brass work hardens as it is drawn
into wire; what we typically use for model building is rated "half hard". IIRC,
the hardness of the finished wire is controlled by annealing it at intermediate
points in the drawing process; it would seem DA got a batch of wire that is
harder than optimum.

As Tony said, you can anneal brass by heating it. Unfortunately, this will
return it to its dead soft state, and is not reversible by further heat
treatment as steel is.

Thanks Tony & Randy,

So the better choices seem to be either .01" brass or .008 music wire (I
assume that is stainless or something of that sort). Or to muddle along
with a high failure rate using the .008 brass.

I think I'll give the music wire a try next.

Or try .008 brass from a different source. Brass work hardens as it is drawn into wire; what we typically use for model building is rated "half hard". IIRC, the hardness of the finished wire is controlled by annealing it at intermediate points in the drawing process; it would seem DA got a batch of wire that is harder than optimum.

As Tony said, you can anneal brass by heating it. Unfortunately, this will return it to its dead soft state, and is not reversible by further heat treatment as steel is.
