Therefore, making this kind of steam engine for Ma Lin is still very challenging.
Putting everything else aside, he first needs to fabricate a lathe with enough precision.
His lathe is water-powered, spinning over 120 rotations per second.
It's incredibly powerful, more so than two strong men using foot power.
For such a large-diameter tube, is it more appropriate to use a lathe or a boring machine?
Thirty centimeters in inner diameter.
His tools are exceptionally outstanding.
He thought it would be more suitable to process using a boring machine and fix the tool in place.
Then rotate the metal block to be processed.
After trying, he felt that reversing the process was actually fine too, rotating the tool and fixing the metal block.
Both the tools and the rotation and sliding shafts must be very standard.
The metal block must be secured very well.
The tool's tip is made into an inverted V shape, so as the tool is pushed inward, it enlarges the hole in the metal.
