I do not recall Col Conk soap being one of the better latherers out there, but what I do is put hot water onto the soap and soak the brush. Then I squeeze out all the water from the brush. I use pressure to gather up lots of soap and then add a little water until I get an explosion of self supporting lather. I think your not getting the right amount of soap, mixed in with the right amount of water. Then I think you might also not be airing it up right with the brush.

For me the entire affair is a little violent. Try being a little more forceful about the whole thing.
