There is a cut tube from a small bicycle on the wheels.

The structure is too slender for metal.
You can cut everything that is wooden, plastic, I think that soft metals such as aluminum and brass will not be a problem either. For steel, it is probably not due to the lack of cooling, although small details would probably also be fine to cut. Of course, you would need a different tape for metals.

I build a saw, but with a lowered arm, mainly made of metal (it will be possible to set the arm vertically and after tightening the korzustania table like yours)
The gap between the bearings can be adjusted depending on the thickness of the strip.

A two-speed motor from an automatic washing machine was used - probably not even 200W, at a rotational speed of 2800 rpm - the saw can at most speed up empty and also quite reluctantly. This one. The second - the saw drive wheels themselves - with any tighter tension, chips will fly out of the rubber. So I would love to see this machine in motion
As I wrote earlier in the days the engine will be replaced, this one was only for the test how it all turns. The test is passed so the machine will get a bigger engine and it will be ok. This one is actually a bit weak. as for this rubber, contrary to appearances, it is very durable. I watched a lot of DIY constructions of such saws on the Internet and in most cases this is the solution. Simple, cheap and effective.
