If you look at the two examples in the pictures I included before you will note that the real one has a triangular shape to the support and the one in the grey sort of "concept" picture has a straighter square type support - the drawing I made up has the triangular type support - but you can hack out anything you would prefer. Also the 9" is getting small so 1/4" may be a bit to thick for the support and you may want to go 3/16" The holders or stays are the same for all models as they seem to work well as 1" diameter and scale that way off the 11" Utilathe drawings.. I also drew this with changeable ends for the followers - you could make them out of PTFE, Brass, Bronze or a selection of material - even a roller bearing if you got really excited about it.
