Resin Freight Car Build
« on: September 11, 2017, 08:20:07 AM »
I thought I'd cover the process I use to build a flat-sided resin freight car kit, in this case a boxcar, and document it here. I also plan to document this same process over on my steam era freight car blog.
In keeping with the first post for any build tradition, here's the assortment of parts you find when you remove them from the box. This is fairly typical of a resin freight car - although this particular car has some additional parts not usually found in a standard boxcar kit.

You'll notice in the closeup image below, things like the gear mounting for the brakewheel, and the cylinders are included in the resin "sheet" - rather than mess around with trying to clean up the resin around these parts I usually replace them with aftermarket detail parts.

In another section, you'll notice the ladders/grabs are also included in the resin sheet - I think for this car I'm going to try and substitute the ladders with etched brass ladders - for better appearance and a much more rugged model.



I won't specify which kit this is - yet.
In fact I plan to build two versions of this car, one for the "as built" configuration and paint scheme (roughly, the mid-1920s) and the other a "modernized" version that shows how these cars looked in service in the late 1940s/early 1950s. (that's the version shown in this photos)

Marty,
       I'm glued to this build.  I have about a half dozen resin car kits remaining to build.  I've built 2 and one plastic/resin kitbash.  Resin kits (being easy to flash remove) remind me of the early (old) metal cast kits (not so easy to flash remove) when I was an young adult (adult being used loosely here).  I'll be watchin Obe-Wan.   Thanx Thom...

Marty...

Great start to a thread.  I have built several resin kits over the years and found the detail to be terrific.

I have had great success using super glue and the pace of construction is also fun, as compared to wood kits that require longer drying times for some steps.

At times I am angered with warped parts and no recourse as some manufacturers are no longer out there to provided replacement parts.  I have had fair success with pulling out some warps with interior structuring but that also has its limits.

Again thanx for starting this thread.

see ya

I've had good luck removing warp from resin parts by heating the oven to about 150, then turning the heat off.  I put the 'offending' part on a piece of granite (so it's definitely flat) and let it sit in the oven for a half hour or so.

Ditto that.  I've built a few over the years with varying degrees of success.  I've got a few more in the stash to build someday.   ::)  Always looking for ways to improve.  Thanks for sharing.

I ended up working until almost 8:00pm last night, so the only thing I had time for before collapsing into bed (that 5:18 am train leaves early....!) was to clean the parts.
Different manufacturers use different mold releases - some of them are really hard to clean off completely - and you won't realize it's still there until you try to paint the model and the paint either beads up or comes off in sheets. Sylvan mold release is the toughest. No matter which manufacturer, I start by cleaning the parts before assembly, and then follow up with a pre-painting touch up cleaning. 
I've tried warm soapy water, Goo Gone, Sylvan resin prep (which I'm pretty sure is some form of Goo gone), but one thing I've found always works pretty well is Shout.


So, for this car, once I removed all the resin sheets from the tissue paper wrapping I gave each of the parts a shot of "Shout" (yes, the laundry stain pre-treat stuff) and scrubbed them gently with a toothbrush  before rinsing them under warm water. Then I put the parts aside to dry.

I've had great luck using a 10% solution of "Super Clean" (automotive cleaner section of Wal-Mart) for cleaning resin parts. That stuff also works great to clean the oven hood, so I got brownie points from the wife for that :-)  And I have a dollar store battery toothbrush that works great to clean around the cast-in details.

Surprised to see no one has ventured a guess as the prototype for this car....I thought it would be easy to figure out.

Looks very similar to the FEC 1700 series ventilated boxcar from 1920. However, the FEC had a slightly different style side door.

Tom,


Hope you came through the hurricane intact....
And you're very close but not quite right....
the answer should be very, very easy for you...

I don't use a lot of fancy tools to build these kits, mostly a razor blade, an X-acto, some sanding sticks/files, pliers (to form wire), tweezers, a small machinists square, and in the starting in the last few years, an Opti-visor....
For drilling holes for grabs and brake components and the like, I prefer my drill press - but since it's packed up like the rest of the shop, this model will require the old fashioned (but perfectly serviceable) pin vise.


Two tools that I find are really useful are shown in the photo below:
The NWSL True-Sander
Coffman right corner clamps

Of course, the ACL Class O-17 17000-18999 series ventilated boxcars. How did I miss it? Thinking to much I guess.
