Hi,
at the moment I build a roadbikeframe with stainless chainstays.
Therefore I had to build some backpurging tools and realized that arc stability gets better when I backpurge the thin tubing (also crmo). Normally I had the impression that the arc tends to wander when I have full root penetration and the inner of the headtube for example is melted up (that´s where the inner surface gets lumpy, and when backpurged stays shiny and nice).
Is that something someone else experienced?
So maybe I will allways backpurge now, even on crmo.
