It’s illegal if it’s patented and, even if you win, can you afford a lawsuit? Can you actually afford to get sued? Even in my lawsuit that I won, I had to cough up before even knowing for sure that I was gonna win.
It’s still intellectual property theft and if you are selling designs copied from a company and they find out, you will incur their wrath, right or wrong.
You can’t patent skateboard trucks. The design has been around for quite some time. Like I said patent is only valid for 10 years.
Most manufacturers who manufacture them most likely use the same design, but in order to save on costs makes them out of inferior materials such as die cast zinc, cast aluminum, or whatever. So perhaps “good” ones are good due to their machining, material selection, bearing quality, etc.
My neighbor makes aftermarket parts for scooters, some of them copies of well known brands. He did it for a long time and did not get sued for it. The aftermarket part in question (it’s brake calipers for scooters) is made from cast aluminum, delaminates with age (no idea why), and costs 20,000nt a set.
They won’t sue you anymore than Martin suing luthiers for making copies of Dreadnought guitars.
This is why I want to do this. If I can acquire my neighbor’s CNC machine I can produce them in mass, sell it cheap enough to stores that I can make a decent profit. Even if I make only 50nt a piece, but I make 10 pieces an hour, it’s still a good profit.
Would making the boards need less start up money? I made them from hardwoods as a teen and made a few for others at cost. Trucks on the other hand, you need rubber and various other parts besides the metal parts and maybe more and need be mass produced to be profitable (Independent Trucks a major high end brand is made in China, not sure you can make a profit with higher factory costs in Taiwan). Boards can be hand designed and made one by one on the other hand.
