Is there a way to resize bones or a work-around for achieving this?

Is there a way to resize bones in Roblox like how I’m doing in the video above?
(Top left shows Pose Mode)

Currently, I can only rotate or move bones in Roblox but not Resize.

If this is not possible, is the only way around this to put a bone at each vertex and move them all outwards? (Or is there an easier way with less bones?)

It looks like you have both the cylinder and bone selected in edit mode at the same time. Try only selecting the bone then going in to edit. If that is not the case, you can inpatient them then resize it then re-parent them.
