Still suffering from a lack of time - as I try to get into the operation of a CAD software (Autodesk Intenvor®) - I decided to build at second a bulkhead flat wagon, based on another pre-mounted and pre-treated wagon frame from Frithjof. Theses frames where soldered in a special kinda assembling jig, designed and built by him too.

Apart from this pre-mounted frame I'm going to use real ball bearings (diameter 3mm, width 1mm) in DIN axle boxes (brass castings) with custom made (lathed) brass axles. The feldbahn wheels have an inner part of resin and a steel rim. These ball bearing bedded axles run phenomenally good (as long as they are proper adjusted) ... 8) ... and have been approved on my flatcar (http://www.feldbahnmodellbau.de/viewtopic.php?f=5&t=21&start=0).

I like how it balances on two wheels ! ::)

FYI All major league baseball umpires must wear "Black" underware! Just in case they split their pants?
Very neat. I look forward to seeing what you do with this.

I got the basic frame of the flatcar modified, soldering L-shaped brass profiles to it, followed by strut sections (support/donation from Frithjof) for more stability made out of Neusilber, a kind of alloy consisting of copper, nickel and zinc.
It looks a bit scruffy at the moment, as I am not quite familiar with metal modeling techniques yet, but let's wait and see ...

FWIW I like using a blast of baking soda (In an air eraser or similar) after soldering.
It cleans very well and leaves the slightest texture.
Not sure how versed you are in soldering but flux is the secret, that and using as little solder as possible.
Often what will stick on the tip of the gun/pencil is even more than required.
Or just tinning the parts and re-heating.

... unfortunately I do not own any air eraser or something similar, my workshop is more or less "low tech", happening on my desk or kitchen table ...

... thanks for your feedback. I'll give it another try. May be my partial inadequately soldering results depend on a lack of practice ... ?
