Sure, but that VB6 is for beginners. All the advanced stuff is only in books (networking, sockets, concurrency (which is an absolute nightmare in VB6), etc.). And, note, the primary purpose of that website is to
sell a book.
And, as for screw threads, tap and die simply aren't accurate enough for stuff like watchmaking (although with modern technology--carbide cutters, titanium materials, CNC machines, etc.--they might be).
The screw thread question wasn't hypothetical. I actually asked at a fairly big machinist's meetup how to do that on a jeweler's lathe. Nobody knew how.
The answer, it turns out, is that they would build a custom power feed. This is documented on p62-76 of "Practical Benchwork for Horologists." This is such an important concept that the book devotes more than 10% of the "Tools and their Uses" section to it and it's the only thing in the book with actual plans.
Yet nobody now knows. And I had to figure out where the answer might lie with very little guidance. And I had to buy the book blind to figure that out. I got lucky and the book was $20 (it's normally about $200) so I took a flyer (It's a wonderful look at the art of machining. As I explained to my wife why I found a nearly 100 year old book so entertaining--"It's engineering porn. You're not supposed to understand.")
I couldn't request it via interlibrary loan from any library in my purview. I couldn't find the knowledge online.
And this wasn't a terribly rare book. Sure, it wasn't a bestseller, but it went through 7 or 8 editions over about 70 years. There is zero reason for it to be gone other than the libraries threw it out.
