I am currently working with carronade machines. I will tell you more about it here.
The roller itself is 2 brass tubes. One is 1.5 mm, the inside is 1 mm in diameter. We insert one into the other, solder and grind to size (in this case the width is 2.4 mm) as a result we get a diameter of 0.5 mm for the axis.
The parts in the photo below for the roller frame were cut out for me on a laser machine. Length 5 mm, width 1.0 mm, thickness 0.2 mm. I drilled 0.4 mm holes, although initially 0.5 mm was supposed. But very little is left on the edges of it, and I made the axle thinner
As a result, we get such a product. Please note that this is still a macro shot
The set offers this version of wheels for a carronade machine. Something glued together from three parts. I think the difference is obvious
The most interesting part came next. What to make the slabs for the gun from. In the original, they were cast from cast iron. At first, there was an idea to make them from black hornbeam
It should look like this. The manufacturing process is in the photo.
This is a photo for the post above. I made a scraper, made a profile from hornbeam, then cut and drilled
The idea was rejected
While I was thinking about a new idea, I started making parts for the machine. Side eyes, the trousers go through them.
Ultimately, this resulted in a new idea and here is its implementation.
