How do you lather in a scuttle? I just purchased a Dirty Bird 1.5 scuttle and cannot seem to figure it out. I am using a Shavemac D01 and Tabac shaving soap. I load the brush and then start lathering in the scuttle and get an awful lather. If I add any water, all I get is a wet mess. If I lather in a bowl, I get a perfect lather. What gives?
