Here is another photo of the museum ship “St. Nicholas”:
There is, however, one nuance here:
“After the October Revolution of 1917, the ship was renamed Nikolai. In 1927, the ship was converted into a non-self-propelled oil barge. In 1960, the ship was sent to the ship graveyard. In 1970, the ship was restored."

The model of the ship we are making will have a steam engine. Let's start with him.
I assembled the steam engine when I was working as a mechanic in a garage, according to drawings from the Young Technician magazine. That article was called “Our Grandfathers’ Toys.” It proposed building a model of a boat with a simple steam engine with an oscillating cylinder. Actually, I made only two parts on a lathe - a piston and a cylinder, everything else was done by hand. I picked up a ready-made flywheel from some cassette recorder. At work, I drove the machine from the compressor, it worked fine. Then there was no time for steam engines; the car lay idle for a long time. Last year we decided to solder the boiler and check how it would work using steam. The boiler was soldered, but then they started building the bireme, and the steam engine was put aside again. Finally, this year it was the ship’s turn. First, we tested the machine by heating the boiler on a gas stove. In order to know the working pressure, we bought a 6-bar pressure gauge. Now we have assembled the firebox in a rough version, ready for installation on the model. But they haven't tested it yet.

What criteria should wheels meet?
The answer suggests itself to be cheapness, but this is not so.
First of all, withstand the load. Weight consists of:
- the average weight of an inflatable boat is 30-60 kg;
- engine with gasoline another 30-50 kg;
- Let's take into account the minimum of things on board: pump, gear, anchors, etc. +10-20 kg.
In total, it turns out that the structure should be designed for a weight of 70-130 kg. The load will be distributed both on the metal elements and on the wheels.
Secondly, the reliability, functionality and durability of the design. You need to understand that the area of responsibility will include a stand, a fastening mechanism and a platform. All this should ideally be made of stainless steel or a steel profile of the proper thickness. While it is better to take purchased wheels of decent quality.
