No, I think you misunderstand how modifiers work.
If I understand it correctly, your skill (and tools) determines the quality of items you can potentially make. The modifiers then affects the success roll, so with a massive bonus you'll almost always manage to make the best you can make, but it won't make you a master.
You need a skill of 20 to be capable of producing decent items, 40 for fine, and 70 for superior ones.
It's supposed to be a slow going for starting characters with low skills. If you don't like that you should probably start with better characters, rather than making the game easier. Also note that making it easy means you'll reach the top a lot faster than intended, which can be boring.
