Sad to see racist yellow scare bogeyman stuff going on at every little thing. You really think Sherline had some amazing hobby lathe IP that was just so far intellectually beyond what an educational powerhouse of a country with 1.6 billion people could ever come up with?
Yes, I agree that China can copy Sherline’s IP and it’s a form of theft. An estimated 70-80% of the parts can probably be made in China. If you would like a breakdown I can provide it.
Sherline, for example, specifies spindle nose runout of 0.0005 inch or less and spindle end play around 0.0002 inch or less, using two 20-mm ball bearings with adjustable preload. That’s only about 13 µm runout. A Chinese factory can absolutely manufacture that.
Manufacturers such as SIEG took conventional lathe architecture and mass-produced it.
There is nothing original going on there lots of copying
If you can quote spindle runout, you know perfectly well that there's no meaningful IP in this market segment. That would have been achievable by any number of manufacturers a hundred years ago.
It's a pure manufacturing cost play to make something precise enough, rigid enough, and light enough[0] while being inexpensive enough for the market segment it's aimed at.
Is it a bummer that a US manufacturer went out of business trying to make money at that play? Yes. Is there anything nefarious going on with IP theft? Absolutely not.
[0] This is being sold to customers who don't hire riggers to move their machines.
They can't. But how is that unfair? It's literally a choice we made.
And it's the one thing that unites every mainstream politician against Trump - they can't agree on tons of stuff, other than that we definitely should not be using tariffs to defend local manufacturers against Chinese (or any other) imports. I've been assured that those jobs are "not coming back." Well, big surprise - they're also not going to stop disappearing.
I agree some policy choices were made to get us in this situation. Biden largely left the first Trump era tariffs in place. The disagreements are on the broadness of them
