For your own use, I dont see a problem, but if you started selling them, you may run into some patent or copyright issues?

Since the woodchuck and the skogger are copies of another tool, the Ci1 from Easy Wood Tools, I don't see how they could complain about someone else "stealing" their idea and marketing it.
I made my own, and bought the tips from Bitshird. I spent more for the M5x.8 tap and drill than I did for everything else to put it together. If you have the ability I recommend you make your own. Otherwise I would say buy from a reputable vendor.

You can make your own tools all day long. Just don't sell them unless they're unpatented or your own design.

here is a link to a tutorial on making your own carbide scraper

The only real challenge is getting the inserts. Most require a purchase of 10 inserts, which would probably be a lifetime supply of inserts for most turners unless your turning alabaster.

It's really pretty easy to make your own tools, The only trick is to get the radius inserts to sit firmly in the pocket of the tool holder, as far as using round stock for the tool bar, I would advise against it, with a square cornered carbide insert it can catch and put some serious strain on your wrist, that's why I use square stainless stock, I've sold quite a few inserts to guys to make their own tools, I really don't like the idea of leaving the tang portion of the tool square, unless you make you handle the way Keith Larrett made his for the original woodchuck, you remove too much wood which plays hell with your safety margins. The radius inserts need a radius at the rear to keep them steady. and they cut with a higher degree of control you just have to be careful not to over tighten them, and just a s bad or even worse is allowing the insert to spin slightly in it's seat, good way to guarantee a nasty catch, as far as copyright or patent, I did copyright my machine code, but a patent on this type tool is pretty useless, besides being hard to prove, The one thing to remember is that carbide is very hard it is extremely friable, that means it can shatter easily, Grinding and filing may not get the seat flat enough, A milling machine work best for that application, Actually hot rolled steel is better than cold rolled, and Stainless is better than hot rolled. Every credits Craig Jackson with starting the carbide revolution, but he was about 10 years too late, I have some tools that were made by an old wood turner / Blacksmith he silver soldered hand ground carbide pieces on to steel bars for hollowing tools, I'm making a set of hollowing tools that way for my self, so I'll have interchangeable tips. I encourage guys to make their own tools when possible, as long as they realize what they are getting into, and make sure their tools are safe to use.
That's why I sell inserts separately, and now I've got a better price on some,
