building new siege weapons

[aww1st]

I use siege weapons as an example. I have 4 siege workshops, but an unable to build new ones. I don't understand why not. I can't figure out what the criteria is to recruit - for example sometimes I can recruite a large number of pikemen, and other times only a small number.

the criteria is the amount of resources. Or you dont have enough resources for new ones, or the reources, if you have them, are not in the province on wich you want to make the recruitment.
Also, the amount of soldiers proposed for recruitment on a given prvince depends on the amount of resources located in your capital, and also on the carying capacity.
also, the capacity of baracks (gives the amount of a group to be trained) and the level of "Military skills" ( the level give the number of groups that can be trained, one by one)
