The original post and subsequent ones questioned the jobs listed [ Cotton weaver,Wool comber,blacksmith,out door labour,tool maker,yeast hawker,iron turner/mechanic,iron broker,marine store dealer,brass finisher,hawker.] and whether they would be likely to be undertaken by travellers. I would think that any trades entailing a 7 year apprenticeship, almost certainly in one place would not be.
Of the list wool comber, blacksmith, toolmaker and iron turner/mechanic would be the ones needing an apprenticeship, and to mind not fitting a travelling life style.
Cotton weaver, depending upon when and where, could be an apprenticed trade.
Of course, anyone can stay in one place and take jobs that do not involve travelling, sometimes for a short period of their lives, other times for life.
