Sorting lathe out

4 Feb

I am finally getting around to sorting out out my Faircut Junior lathe. It’s currently fixed on to a rather battered MDF board, and it’s really difficult to adjust the belt tension,and/or change which drive pulleys are used.
Plan is to make a proper stand, which is the correct height for myself, and to use an arrangement somewhat like the following sketch to tension the belts…

Am still doing work on the free body diagrams to determine the correct relationships between belt length, belt tensions, strut length/angles, and hinge positions.
