I was going to state that, but Paul beat me to it. Over the years a LOT of model railroad tooling has been "soft" tooling, because it's cheap.  The choices are, in order of increasing hardness/durability:

Kirksite (a cast zinc alloy)
Brass
Aluminum
Mold steel (a tool steel such as P-20 used in a semi hard state, soft enough to cut with conventional milling, with no further heat treatment.)
Tool steel (which is fully hardened and then worked by Electro Discharge Machining and grinding)

Kirksite could be cast over metal patterns, same as rubber molds are made. If damaged it is not repairable. 

Brass was a favorite of people who came into toolmaking from engraving. A lot of Grandt Line tooling is brass. It is difficult to repair, due to its softness and low melting temperature.

Aluminium is a favorite for CNC machining of cavities because it cuts easy and doesn't break small cutters. The old Front Range line was completely aluminum tooling. It is slightly harder than brass and more easily repaired by welding.

P-20 was a favorite of the old model car manufacturers. It is easily damaged, but weldable.

Tool steel is the gold standard, and welded repairs should be undetectable.

While there are surface treatments that can be applied to give a more wear resistant surface to most of these mold materials, the problem is, in our world, most damage is denting from closing on stuck parts rather than abrasive wear, and surface treatments are ineffective. However, for items produced with quality tooling, the millionth part should look no different from the first.

Harvesting Dirt Collectors

Bill Welch
 

For about a year now i have been installing the Dirt Collector to the AB Valve. The Dirt Collector is included in the Tichy "AB" Brake Set and on the Styrene Sprue of the discontinued Grandt Line/Detail Associates sets. IT is in some Westerfield kits like the ATSF Bx-11/-12/-13 series of kits.

Today as I was working on my CB&Q XM-17/-18 kit I started to wonder what to do as there was no Dirt Collector in the kits resin AB brake parts I was assembling. I could use a rob a Tichy set or a GL/DA set but I would still be short when I used one of those sets. Hmm. Wait a minute, there are Dirt Collectors on the rear end of the Tichy KC brake cylinder and I have several of those sitting around so i took a closer look. If I clipped it off just so, it would leave a piec long enough to fit into a hole drilled into the resin AB valve I was using. It I trimmed the other end just so, it would be wide enough to drill a #79 hole. The photos show the result.

Now I also have a backup if I drop one of the Tichy or GL/DA parts.

Eliminating flash by facing off the mating surfaces of a mould seems like an act of desperation to me - admittedly one which I might be tempted to do if short on funds and the tooling had not yet earned a reasonable return, but I would have my limits.  I have worked on jobs where badly worn fine-tolerance parts such as shafts that run in plain bearings (NOT 'friction' bearings, that is not an engineering term!) were restored to original size by metal spraying (a bit like welding spatter but finer) and refinishing.  Lesser wear can be restored by metal plating and polishing, but both these methods are more costly than simply skimming the mating faces in a surface grinder.

Re: Nalco Weed Sprayer and tank cars

Jack’s models are of a Fairmont weed sprayer. I supplied him some photos of the Fairmont Equipment. Fairmont also built a weed burner.

 

The M&StL converted a GE gas electric, GE-25,  to a weed sprayer outfit, with sprayer boom arms at the rear, extra windows cut in the sides, and towed a tankcar full of chemicals. Worked fine until it caught on fire in 1963.

Brian/all,
  These photos seem to be "post 1960" to me.  Among other clues I notice
that in the last of them there is a guy wearing what looks to me like a
fairly modern "safety vest" (yellow/orange).

  I'm not complaining - just asking the question "probable image date?".

  If any of you haven't seen it ... search for images of Jack Burgess's
excellent model of an early weed sprayer.  I think you will find them
easiest if you look in recent (last year or two) PCR convention contest
photos.

Earlier runs often better than late runs

Andy Carlson
 

I mentioned once years ago, to my friend Terry Wegmann, that I was looking to get 2 of my most favorite kits of all time--the Bill Gould 4-course tank cars.  I told him that I was only going to purchase kits boxed and sold as Gould kits, as I felt that the parts cast and offered for sale from Tichy to have been cycled more times than earlier runs and was troubled about parts quality. I was half expecting Terry to give me his "are you crazy" response but Terry was in full agreement with my reasoning.

He mentioned an extreme example of later shots from tooling suffering over time was the Cal Scale plastic AB brake set. He said that the mold face of the two tool sides would degrade enough that flashing was getting too severe. Cal Scale's solution was to surface grind the meeting faces to solve the flashing. This repair was apparently done more than once, and Terry said that he could identify what generation of brake shots he looked at by how far from cylindrical the air reservoir component deviated.

So to me both Intermountain and Red Caboose kits should be better in the older color printed boxes than the later non-colored boxed kits. Though I have to admit I often can't see any real differences in these two brands of new vs. older.

Hi Tim,

This is a very interesting photo, but I'm not sure it represents the ERDX cars in my 1952 ORER.  The overall length of the 1952 ERDX 9000 series was 42'-6", and all the other MDT owned cars were 41'-6", and the 9000 series had a 2601 cu.ft. capacity while most other MDT cars had capacities from 1900 cu.ft. to around 2000 cu.ft.  The 1952 9000 series also is clearly listed as an AAR Mech. Designation RB, and they have a Note F that states, "Cars numbered E.R.D.X. 9000 to 9999 and M.D.T. 9955 and 9962 have sliding doors 5 ft. wide and 7 ft. high."  All other MDT owned cars had 4 ft. wide by 6 ft. and a few inches high.  Also, there were only 38 cars in the 9000-9999 series and apparently only 2 in the 9955-9962 series.

I think the ERDX 9772 in your photo is an earlier car, and it has ice hatches on both end of the roof and its lettering states "Ventilated Refrigerator".  I don''t see a built date in photo, but the capacity is clearly 2086 cu.ft. and the I.L. is 33ft. 11 in. which doesn't match anything in my 1952 ORER (MDT, FGEX, etc.).  I wish I had my Westerfield 1943 ORER to see if there were other cars of this size as that date, but it's in storage.  

Curiouser and curioser.  Does anyone else have anything to contribute?

Hi Armand,

    Can't help with the idiosyncracies of the of the various ERDX cars but as you know these cars, at least all that
I am aware of, were NOT refrigerated. They were insulated as they were used to to bring seed and other material
from the Eastern States Farmers Exchange warehouses and processing plants as far away as Black Rock
(Buffalo) NY to their local stores all over New England. I don't believe that any of their cars were over 41 ft. in length.
Decals in HO scale for the #10000 series cars are no problem. You can get them from Jim Abbott of Highball
Graphics for $8 for a set that will complete one car. If I could find my decal box that has not been seen since the
move I could bring a set the next time I'm over.

My best, Don Valentine

Hi Bob,
 
Nice photo, thanks for calling our attention to it.
 
Since the image was taken in 1932, the car would not yet be terribly old, but it already required patch panels along the entire car side.
 
Note also the car has not yet been repainted with the Circle Keystone emblem.

Hi List Members,

 

In the image linked below, we get a nice view of the LIRR/PRR yard at Sunnyside, NY. I could wish for it to be a bit sharper in terms of focus, but still an nice view. While web site claims this to be 1900/1905, it is clearly much later, likely during the 1930s in my estimate.

 

Lots of things to see - LV twin hoppers, Armour Refrigerator lines reefer, CG ventilated boxcar, just for starters!
