I was taught in school (by an excellent teacher, who taught in the Mare Island apprentice school) to set the compound at 30 degrees off the cross feed axis, and subsequently, all the journeymen in my apprenticeship shop did the same. I was told that the Germans at least set their compounds to 90 degrees to the cross axis and fed in with the cross feed so much and on the compound at each infeed to approximate a 30 degree infeed, I suppose that they wanted the compound to be left in position so as to be able to use it to measure axial tool adjustments.
In my opinion, carbide threading tool have little advantage in a hobby shop and are too easily chipped/broken; if one does not like to grind HSS tools, Aloris threading tools are great as they only need be sharpened on top, and last many years before replacement is necessary.
