Introducing project: a tank container collection
This week I’ve reworked my older tank container into a collection of different options, so they add some variety to the layout. For now, there are 2 ...
Another tank container
This week I’ve added one more tank into my tank container collection, codename frame2. It turned out to be much more complicated that previous design...
Another tank container assembled
I’ve assembled, primed, sanded and painted second container variant (frame2). Here are the pictures (along with frame1 variant). New variant is in red.
Project: Flatcar series 13-401
A new project: Flatcar series 13-401. A model of a flat wagon, which is widespread in USSR, Russia and other 1520mm guage countries.

One weekend build: a gondola wagon
This weekend I’ve done a short project, which was printing a gondola (model 12-1592) car in HO scale.
A gondola wagon, now with cargo
Making cargo for a gondola ended up being longer than printing the gondola itself. I had some sticks and branches lying around, that I cut to length and g...
Working on Soyuz rocket transporter
I have finally started to work on assembling 11T750 wagon for Soyuz rocket train.
Latest projects: K-701 heavy tractor and Yaroslavets river boat
So, finally an update on what I am currently doing.
Introducing Project 376 Yaroslavets riverboat
A new project is released on this website and on Printables (thingiverse and cults will follow soon).
Updates for February and March
So, here is what I’ve been doing for the past 2 months.
Slip ring ideas, two of them
The functional crane model I’m working on requires a slip ring to rotate superstructure. Currently this is implemented as a 3D-printed casing for bron...
Winch based on N20 gearmotor
Any functional crane model obviously requires a winch (or two).
Experiments with cast solder
In portal crane project the hook has to be as heavy as possible, otherwise the threads will not be tightened enough and will skip all the time (and will l...
Casting solder into resin-printed molds
Last time I tried to pur solder into a hand-cut cardboard "mold". The result was as inaccurate as one would expect. My attempts to smooth it out with epoxy...
Crane updates
The crane mechanics is close to completion
Useful parts: pogo pins
I’ve recently encountered spring-loaded pogo pins for PCB testing.
Updates on the projects
There were no updates for a long time due to my vacation, but finally here are some.
