Give a man a fish and you feed him for a day, teach him to fish and you feed him for a lifetime.
My personal belief is that real help is NOT posting factoids. The art of instrument repair is exactly the same as the art of playing. Learning it is a process. True help is starting with basics. A good teacher will insist on process.
Granted, there are plenty of DIY hacks for just about anything. I am greatful that we do have people preaching process and offering food for life instead of "quick" patches. There is nothing wrong with experimenting, but if one asks for help at a specialized forum, my belief is that they should get specialized help.
