Flatcars Prototype: Lessons Learned from the Operation Session

Our Summer Operation Session was a lot of fun, but most of all it was informative. I learned three very important lessons concerning my flatcars:

  1. Frame-mounted couplers need large radii
  2. Bogies need clearance for operational reliability
  3. Bogie-mounted couplers increase reliabilty

No.1 Porter: Chain Winch

Besides other insights, the Summer Operation Session 2020 revealed that my Porter needs a better stowing place for the shunting chain.

On the one hand the chain easily drops from the loco if it isn’t properly secured, on the other hand it’s quite fidgety to fixate the chain at a given lenght. So I more or less spontaneously got the idea to tinker on a chain winch.

The first steps happend on a whin and I was sure that they wouldn’t succeed, that’s why I didn’t take any pictures. But after I realized I was onto something, I made some after the fact.

Flatcars Prototype: Floor and Trusses

After preparing the frame and floor boards, construction can continue with the underframe. The main components are the body bolsters, needle beams and trusses. Unfortunately, I don’t have got a complete set of diagrams, so I had to guesstimate concerning the longitudinal and cross trusses. However, it’s not rocket science.

Flatcars Prototype: Materials and Frame

Based on my experiences from the flatcar experiments I’ve decided to construct a prototype for 26′ flatcars. The model is going to be built from red cedar and purchased Piko bogies.

Flatcars: Experiments

Before I start the actual construction of my planned flatcars, I’d like to know first which limits the tracks will pose on them. I’ve only ever known classic model waggons, which have their couplers on beams attached to the bogies. This design ensures high operational reliability because the couplers can follow even the tightest curve radii. However, it’s not a pretty sight.

So I’d like to build a few test waggons in order to learn how the couplers perform when attached to the waggon’s body.

Joyrider: Setbacks and Corrections

Finishing the covering was another milestone for me and I was very confident that the maiden flight would turn out just fine.
Then the first complete assembly came along and with it some new challenges. Namely undercarriage and center of gravity.

Joyrider: Covering

After the details are finished I can finally focus on the covering. Some model builders seem to regard covering as an irksome work and necesarry evil, but I actually enjoy it. To me it’s like a metamorphosis: the bare framing of the aicraft, as pretty as it is, equals a caterpillar, which is yet to become a butterfly.

Nonetheless it’s a lot of work all the more if one wants to get a creases-free result. In the process, I didn’t manage to take a lot of pictures, but I’d like to give an example and point out some crucial points.

Joyrider: Last Details

By finishing the linkage the out-fitting has come to and end an I can take care of the last details. Those cover two areas: the fuselage and the wings.

The fuselage needs a couple of maintenance hatches in order to easily gain access to the drive unit, and the tailplane’s servos and fixture. The fuselages’ belly needs to get reinforced, too. And last but not least I’d like to add some details to the nose.

The wings need an additional strutting in order to stabilize the lower wings. And it will surely add to the good looks.

Workshop: New Storage Shelf

Due to well-known reasons I’ve been in home office for a couple of weeks. And since mixing private life and work is downright unhealthy, some office space had to be found in the workshop. That was the trigger to finally create some more storage area.

The most importent requirement which has to be met is a full metre of board-width in order to store raw materiels for modeling. Additionally, the lowest compartment is supposed to accomodate two pedestals which really come in handy while working but tend to be in the way in the meantime.

Bogies: Prototype

As I’ve already described, I’d like to build a consistent set of waggons to build a short train for my porter loco.  Of course, that entails waggons. Which run on bogies. Turns out, it’s not that easy to find suitable bogies for Fn3 which stay in a reasonable pricing range. So during winter 2020, I started busying myself with the construction of a bogie prototype.

A particular “thank you” goes out to Gerd, AKA “Waldbahner”, who published a nice series of posts about 5” bogies on his website. I let myself wantonly inspire by those. Extra thanks to Gerd, who kindly allowed me to use some of his pictures of his own projects.
