How to build the castle fast?

Hi there! I searched for an eternity on Google and on this sub for building a fast castle but can't find any advice on this. (Only find build orders for fast castle ofc)..

My question is: what is the fast castle build order for building my castle ASAP after hitting castle age? At which point should I go on stone? How many workers?

Even if it delays the castle age 1-2 minutes, I have problems to manage my economy after building a second mining camp...
