Cosmas Bauer English

Cosmas Bauer English is the English-language channel of a maker who builds useful things in his workshop. He builds many of his own tools and machines rather than buying them.

The videos follow builds from start to finish, with plenty of metalwork and woodwork. Projects include table saws, a belt grinder, steel clamps, router tables and attachments for angle grinders. Some videos also look at mechanisms, such as a model of a continuously variable transmission. The style is practical and focused on the making, with clear camera work.

Some highlights include:

The build of a full table saw using simple tools, showing how a large machine can be made from basic parts.

How to make long steel F-clamps at home, including cutting, welding and threading.

An attachment that turns an angle grinder into a power file, a narrow belt sander for detailed work.

The channel has around 220,000 subscribers.

Building your own machines means thinking about forces, alignment, materials and safety. Those are the basics of mechanical engineering and design. The channel suits students who enjoy design and technology and want to see how tools are engineered, not just used. Watching a machine come together from raw materials also shows why accuracy matters: a small error early on can stop a saw cutting straight. That way of thinking about tolerances and checking work is exactly what engineering apprentices and graduates learn on the job.
